pls help Jiya is renting a truck to move into her college dorm. The rental company charges $55 for the first hour and then $10 per hour after that. If it will take Jiya 7 hours to move, which explicit formula describes how much it will cost her to rent the truck?

a.a7=55+(7+1)10
b.a7=10+(7-1)55
c.a7=10+(7-1)7
d.a7=55+(7-1)10

Answers

Answer 1

Use an Explicit formula to calculate how much it will cost Jiya to rent the truck for 7 hours .The correct answer is option (d) a7=55+(7-1)10

The rental company charges $55 for the first hour and then $10 per hour after that, we can use an explicit formula to calculate how much it will cost Jiya to rent the truck for 7 hours.

The explicit formula for the total cost of renting the truck for a given number of hours can be written as:

a(n) = c + (n-1)d

where a(n) is the total cost of renting the truck for n hours, c is the cost of the first hour, and d is the additional cost per hour.

Using this formula, we can find the cost of renting the truck for 7 hours:

a(7) = 55 + (7-1)*10

Simplifying the expression in the parentheses, we get:

a(7) = 55 + 6*10

Multiplying 6 by 10, we get:

a(7) = 55 + 60

Adding 55 and 60, we get:

a(7) = 115

Therefore, the explicit formula that describes how much it will cost Jiya to rent the truck for 7 hours is:

a7=55+(7-1)10

Simplifying the expression, we get:

a7 = 55 + 6*10

a7 = 55 + 60

a7 = 115

Therefore, the correct answer is option (d) a7=55+(7-1)10.

An air-conditioning specialist recommends 2 air vents for every 300 f t squared of floor space. At this rate, how many air vents are required for an office building of 21,000 f t squared?

Answers

An office building of 21,000 f t squared would require 140 air vents according to the recommendation of 2 air vents for every 300 f t squared of floor space.

Based on the recommendation of 2 air vents for every 300 f t squared of floor space, we can calculate the number of air vents required for an office building of 21,000 f t squared by dividing the total floor space by 300 and multiplying the result by 2.

21,000 / 300 = 70
70 x 2 = 140

Therefore, an office building of 21,000 f t squared would require 140 air vents according to the recommendation of 2 air vents for every 300 f t squared of floor space.

It is important to note that this is just a recommendation and the actual number of air vents required may vary depending on factors such as ceiling height, insulation, and other building characteristics. It is always best to consult with an HVAC specialist to determine the appropriate number and placement of air vents for optimal air circulation and comfort in a building.

The probability that a student has gone to China is 0.48.
The probability that a student has gone to both United Kingdom and China is 0.14.

What is the probability that a student in Mr. Beal class has been to United Kingdom or China?

Answers

To find the probability that a student in Mr. Beal's class has been to either the United Kingdom or China, we need to calculate the union of the probabilities.

The probability of a student going to the United Kingdom is 0.23.
The probability of a student going to China is 0.48.

However, we need to adjust for the fact that the probability of going to both the United Kingdom and China is already included in those individual probabilities. So, we need to subtract the probability of the intersection (going to both countries) from the sum of the individual probabilities.

Probability of going to the United Kingdom or China = Probability of going to the United Kingdom + Probability of going to China - Probability of going to both (United Kingdom and China)

= 0.23 + 0.48 - 0.14

= 0.57

Therefore, the probability that a student in Mr. Beal's class has been to either the United Kingdom or China is 0.57.

Sketch the triangle ABC and solve it using the law of cosines. Round off your answers to the nearest integer. b = 60, c = 30, ∠A = 70∘
Ams: a = 57, ∠B = 81∘, and ∠C = 29∘

Answers

Answer:

Sure. Here are the steps on how to solve for the sides and angles of triangle ABC using the law of cosines:

Draw a sketch of triangle ABC.

Label the sides and angles of triangle ABC.

Label the known and unknown values.

Use the law of cosines to solve for the unknown side or angle.

In this case, we know the following:

Side b = 60

Side c = 30

Angle A = 70°

We need to solve for side a and angles B and C.

The law of cosines states that

a^2 = b^2 + c^2 - 2bc cos A

where a, b, and c are the sides of the triangle and A is the angle opposite side a.

Plugging in the known values, we get

a^2 = 60^2 + 30^2 - 2(60)(30) cos 70°

a^2 = 900 + 900 - 3600 cos 70°

a^2 = 1800 - 3600 cos 70°

a = sqrt(1800 - 3600 cos 70°)

a = 57

Therefore, side a is 57.

To solve for angle B, we can use the law of sines. The law of sines states that

\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}

Plugging in the known values, we get

\frac{57}{\sin 70°} = \frac{60}{\sin B}

\sin B = \frac{57 \sin 70°}{60}

\sin B = 0.774

B = \sin^{-1}(0.774)

B = 81°

Therefore, angle B is 81°.

To solve for angle C, we can use the fact that the sum of the angles of a triangle is 180°.

A + B + C = 180°

70° + 81° + C = 180°

C = 29°

Therefore, angle C is 29°.

Therefore, the sides and angles of triangle ABC are a = 57, b = 60, c = 30, A = 70°, B = 81°, and C = 29°.

What are the domain and range of f(x) = (one-sixth) Superscript x + 2?

Answers

Answer:

The domain of a function is the set of all possible values for the input variable (x), while the range is the set of all possible values for the output variable (f(x)).

For the function f(x) = (1/6)^x + 2, the domain includes all real numbers, since any value of x can be raised to any power.

To find the range, we can look at the behavior of the function as x approaches positive and negative infinity. As x approaches negative infinity, (1/6)^x becomes very large, so f(x) approaches 2. As x approaches positive infinity, (1/6)^x becomes very small, so f(x) approaches 2 as well. Therefore, the range of the function is (2, infinity).

If Un+1 = 2U₁ + 6 and Uo = 10 find U₁

Answers

Answer:U₁ = 2
.

Step-by-step explanation:

Un+1 = 2U₁ + 6 (Equation 1)

Uo = 10

We want to find U₁. We can start by using Equation 1 with n = 1 to get:

U2 = 2U₁ + 6

We can then use the value of Uo = 10 to find U₂ as follows:

U₂ = 2U₁ + 6

U₂ = 2U₁ + 2(3)

U₂ = 2(U₁ + 3)

We can then use the value of U₂ to find U₃:

U₃ = 2U₂ + 6

U₃ = 2(2U₁ + 2(3)) + 6

U₃ = 4U₁ + 12 + 6

U₃ = 4U₁ + 18

We can keep using this process to find Un in terms of U₁, until we reach the value of n we need. For example, we can find U₄ as follows:

U₄ = 2U₃ + 6

U₄ = 2(4U₁ + 18) + 6

U₄ = 8U₁ + 36

So we have:

Uo = 10

U₂ = 2(U₁ + 3)

U₃ = 4U₁ + 18

U₄ = 8U₁ + 36

and so on.

To find U₁, we need to use the equation for U₂:

U₂ = 2(U₁ + 3)

Substituting U₂ = 10 (from the given value of Uo), we get:

10 = 2(U₁ + 3)

Simplifying, we get:

5 = U₁ + 3

Subtracting 3 from both sides, we get:

U₁ = 2

Therefore, U₁ = 2.

consider an infinitely long three-sided triangular enclosure with side lengths 2 cm, 3 cm, and 4 cm. the view factor from the 2 cm side to the 4 cm side is

Answers

The view factor from the 2 cm side to the 4 cm side of the infinitely long three-sided triangular enclosure is approximately 0.5.

The view factor (F) from Surface A to Surface B can be calculated using the formula:

F = A / (A + B)

where A and B are the areas of Surface A and Surface B, respectively.

The area of a triangle can be calculated using Heron's formula:

Area = sqrt(s * (s - a) * (s - b) * (s - c))

where s is the semi-perimeter of the triangle and a, b, and c are the side lengths of the triangle.

For Surface A:

a = 2 cm

b = 3 cm

c = 4 cm

s = (a + b + c) / 2 = (2 + 3 + 4) / 2 = 4.5 cm

Area_A = sqrt(4.5 * (4.5 - 2) * (4.5 - 3) * (4.5 - 4))

= √(4.5 * 2.5 * 1.5 * 0.5)

=√(5.625) ≈ 2.37 cm²

For Surface B:

a = 2 cm

b = 4 cm

c = 3 cm

s = (a + b + c) / 2 = (2 + 4 + 3) / 2 = 4.5 cm

Area_B = √(4.5 * (4.5 - 2) * (4.5 - 4) * (4.5 - 3))

= √(4.5 * 2.5 * 0.5 * 1.5)

=√(5.625) ≈ 2.37 cm²

Now we can calculate the view factor (F):

F = Area_A / (Area_A + Area_B)

= 2.37 / (2.37 + 2.37)

≈ 0.5

Therefore, the view factor from the 2 cm side to the 4 cm side of the infinitely long three-sided triangular enclosure is approximately 0.5.

A Bernoulli distribution is a probability distribution of a single random experiment that can have only two outcomes, success or failure. Therefore, flipping a coin and rolling a 5-sided die cannot be Bernoulli distributions as they have more than two possible outcomes.

However, the time between visits to a doctor's office can be considered a Bernoulli distribution if we define success as visiting the doctor within a certain time frame and failure as not visiting the doctor within that time frame.

of all the lightbulbs manufactured at a certain factory, 95% of the lightbulbs work and 5% are defective. if six lightbulbs are selected at random from the shipment, what is the probability that at least one of them is defective?

Answers

To calculate the probability that at least one of the six lightbulbs selected from the shipment is defective, we need to first calculate the probability that all of them work and then subtract that from 1. Therefore, the probability that at least one of the six lightbulbs is defective is 0.2649 or 26.49%.

The probability that a single lightbulb is defective is 0.05 and the probability that it works is 0.95. Therefore, the probability that all six lightbulbs work is:
0.95 x 0.95 x 0.95 x 0.95 x 0.95 x 0.95 = 0.7351
To calculate the probability that at least one of the six lightbulbs is defective, we need to subtract this from 1:
1 - 0.7351 = 0.2649
Therefore, the probability that at least one of the six lightbulbs is defective is 0.2649 or 26.49%. In other words, there is a little over a one in four chance that at least one of the six lightbulbs selected is defective.

what is the area of a quadrilateral with vertices at p(3, 4), m(8, 4), n(5, 0), and the origin (0,0)?

Answers

The quadrilateral has a area of 10 square units.

Because the vertices of the quadrilateral are p(3, 4), m(8, 4), n(5, 0).

This quadrilateral can be divided into two triangles.

For the first triangle, we can say that p(5) is the base and m(4) is the height.

Area of the triangle=1/2x5x4

The bases of the second triangle are p(5) and n(0).

Area of ​​the second triangle = 1/2x5x0

Suppose you are interested in uncovering the relationship between snowfall (in inches) in the month of December and the flow rate of Yosemite Falls in April (in cubic meters per second) over the span of years from 2005 to 2010 (inclusive). You observe the following snowfall and Yosemite Falls flowrate data: December Snowfall (X)=[16,19,18,16,20,17] and April Flowrate (Y)=[22,23,21,18,26,21]. What is TSS?
Group of answer choices
About 4.37
About 6.27
About 13.33
About 22.46
None of the above are close

Answers

Answer:

The correct answer is About 6.27.

TSS stands for total sum of squares. It is a measure of the variation in the data. It is calculated as follows:

TSS = Σ(y - y^)^2

Where:

y is the observed value

y^ is the predicted value

In this case, the observed values are the December snowfall data and the predicted values are the April flowrate data.

TSS = (22 - 20.81)^2 + (23 - 21.7)^2 + (21 - 20.09)^2 + (18 - 19.28)^2 + (26 - 23.36)^2 + (21 - 20.55)^2

TSS = 6.27

Step-by-step explanation:

Final answer:

The Total Sum of Squares (TSS) can be calculated by first finding the mean of the dataset, then subtracting this mean from each data point, squaring the result, and summing all these squared differences. The TSS for the provided dataset is approximately 34, not among the given choices, thus 'None of the above are close' is the correct answer.

Explanation:

In this problem, we're asked to calculate the Total Sum of Squares (TSS), a statistical measure used to understand the variability in a dataset. For the given set of April Flowrate (Y) values, we first calculate the mean (average), which is (22+23+21+18+26+21) / 6 = 21.83 (rounded to 2 decimal places).

We then subtract this mean from each Y value, square the result, and add them together to get TSS. The calculation would proceed as follows:

(22-21.83)² = 0.0289(23-21.83)² = 1.3589(21-21.83)² = 0.6889(18-21.83)² = 14.7889(26-21.83)² = 17.4489(21-21.83)² = 0.6889

The total sum of these squared differences gives us the TSS:

0.0289 + 1.3589 + 0.6889 + 14.7889 + 17.4489 + 0.6889 = 34.0034

So, the TSS for the described data set is roughly 34, which is not among the provided answer choices, so the correct answer is 'None of the above are close'.

.in a production scheduling LP, the demand requirement constraint for a time period takes the form
a) beginning inventory + production + ending inventory ⥠demand
b) beginning inventory + production + ending inventory = demand
c) beginning inventory + production - ending inventory = demand
d) beginning inventory - production + ending inventory ⥠demand

Answers

The correct option for the demand requirement constraint in a production scheduling LP is option (c): beginning inventory + production - ending inventory = demand.

In a production scheduling LP, the demand requirement constraint represents the balance between the available inventory and the demand for the product. The constraint ensures that the production and inventory levels are sufficient to meet the specified demand.

Option (c) represents this relationship accurately by stating that the beginning inventory, production, and ending inventory, when subtracted from each other, should equal the demand. This equation reflects the concept of maintaining a balance between the production output and inventory changes to meet the demand

Option (a) is incorrect because it uses the greater than or equal to (≥) symbol, which does not accurately represent the constraint.

Option (b) is also incorrect because it uses the equality (=) symbol, which implies an exact balance between the inventory and demand, disregarding the changes in inventory.

Option (d) is incorrect because it uses the greater than or equal to (≥) symbol, which does not accurately represent the constraint.

Therefore, option (c) is the correct representation of the demand requirement constraint in a production scheduling LP.

The irrational number can be multiplied by -~ 41 to get a product that equals 1 is 1/[tex]-\sqrt{41}[/tex] the correct option is A.

We are given that;

The number= [tex]-\sqrt{41}[/tex]

Now,

To find the irrational number that can be multiplied by sqrt(41) to get a product that equals 1, we need to find the multiplicative inverse of sqrt(41). The multiplicative inverse of a number is the number that when multiplied by the original number gives 1 as the product. For example, the multiplicative inverse of 2 is 1/2, because 2 * 1/2 = 1.

To find the multiplicative inverse of sqrt(41), we can divide 1 by sqrt(41). We get:

[tex]1 / \sqrt{41} = \sqrt{41} / \sqrt{41} \times \sqrt{41}) = \sqrt{41} / 41[/tex]

To simplify the expression, we can rationalize the denominator by multiplying both the numerator and the denominator by sqrt(41). We get:

[tex]\sqrt{41} / 41 \times \sqrt{41} / \sqrt{41} = (\sqrt{41})^2 / (41 \times \sqrt{41}) = 41 / (41 \times\sqrt{41}) = 1 / \sqrt{41}[/tex]

Therefore, by the fraction the answer will be 1/[tex]-\sqrt{41}[/tex].

t (minutes) = 0, 4, 7, 9.
r(t) (gallon per minutes) = 9, 6, 4, 3.
Water is flowing into a tank at the rate r(t), where r(t) is measured in gallons per minute and t is measured in minutes. The tank contains 15 gallons of water at time t = 0. Values of r(t) for selected values of t are given in the table above. Using a trapezoidal sum with the three intervals indicated by the table, what is the approximation of the number of gallons of water in the tank at time t = 9? (A) 52
(B) 57 (C) 67 (D) 77 (E) 79

Answers

The approximation of the number of gallons of water in the tank at time 9 min. is 52 gallons.

Using the trapezoidal sum, the approximation of the number of gallons of water in the tank at time t = 9 is given by:

Approximation =[tex][((t_1 - t_0) / 2) * (r(t_0) + r(t_1))] + [((t_2 - t_1) / 2) * (r(t_1) + r(t_2))] + [((t_3 - t_2) / 2) * (r(t_2) + r(t_3)))][/tex]

where [tex]t_0 = 0, t_1 = 4, t_2 = 7, t_3 = 9[/tex].

Substituting the given values of r(t), we get:

Approximation = [((4 - 0) / 2) * (9 + 6)] + [((7 - 4) / 2) * (6 + 4)] + [((9 - 7) / 2) * (4 + 3))]

= (2 * 15) + (1.5 * 10) + (1 * 7)

= 30 + 15 + 7

= 52

Therefore, the approximation of the number of gallons of water in the tank at time t = 9 is 52 gallons. The answer is (A) 52.

The subject of the linear formula v = u + at is the isolated variable, which in this case is v.

Which variable is the subject of a formula?

The subject of a formula is the variable (which is usually called the dependent variable ) that is being worked out, this is, the variable that is isolated in one of the sides of the formula.

In this case, we have a relation:

v = u + a*t

So v is equal to u plus the product between a and t.

We can see that v is the isolated variable, thus, v is the subject of the formula.

Ezra's ice Cream Shop has two stores, the old store and the new store. Both stores sell ice cream and milkshakes. One year's sales at the two stores are shown in the table. (Hint: make a totals margin to help find theconditional probabilities)

Customers at the old store bought milk shakes about___%of the time.
Customers at the new store bought milk shakes about____%of the time.
Of all the milk shakes sold at Ezra's Ice Cream Shops,___% we’re at the old shop

The options are 80,20,74,26,41,59

Answers

Customers at the old store bought milkshakes about 20.46% of the time.

Customers at the new store bought milkshakes about 26.29% of the time.

Of all the milkshakes sold at Ezra's Ice Cream Shops, 59.29% were sold at the old store.

To calculate the percentages, we need to find the conditional probabilities based on the given information.

Let's calculate the percentages step by step:

Customers at the old store bought milkshakes about:

Milkshakes sold at the old store = 13,400

Total sales at the old store

= 52,100 (Ice Cream) + 13,400 (Milkshakes) = 65,500

Percentage

= (Milkshakes sold at the old store / Total sales at the old store) x 100

Percentage = (13,400 / 65,500) x 100 ≈ 20.46%

Customers at the new store bought milkshakes about:

Milkshakes sold at the new store = 9,200

Total sales at the new store = 25,800 (Ice Cream) + 9,200 (Milkshakes) = 35,000

Percentage = (Milkshakes sold at the new store / Total sales at the new store) x 100

Percentage = (9,200 / 35,000) * 100 ≈ 26.29%

Of all the milkshakes sold at Ezra's Ice Cream Shops, the percentage sold at the old store:

Total milkshakes sold at both stores = Milkshakes sold at the old store + Milkshakes sold at the new store = 13,400 + 9,200 = 22,600

Percentage = (Milkshakes sold at the old store / Total milkshakes sold) x 100

Percentage = (13,400 / 22,600) x 100 ≈ 59.29%

the concept of hedonistic calculus is associated with

Answers

The concept of hedonistic calculus is associated with utilitarianism and the philosophy of maximizing pleasure and minimizing pain. It is a method for calculating the overall happiness or utility of actions based on the intensity, duration, certainty, propinquity, fecundity, purity, and extent of pleasure or pain they produce.

Hedonistic calculus is a term coined by the philosopher Jeremy Bentham, who was a proponent of utilitarianism. Utilitarianism is an ethical theory that states that the right action is the one that maximizes overall happiness or utility for the greatest number of people. The goal of hedonistic calculus is to measure and compare the happiness or pleasure derived from different actions or situations.

According to Bentham, pleasure and pain are the only relevant factors in determining the moral value of an action. Hedonistic calculus involves quantifying these pleasures and pains in order to assess their overall impact. Bentham proposed seven criteria to evaluate the intensity, duration, certainty, propinquity (nearness in time), fecundity (likelihood of leading to more pleasure or pain), purity (absence of pain mixed with pleasure), and extent of the pleasure or pain produced by an action.

By assigning values to each of these criteria, hedonistic calculus aims to determine the net amount of happiness or utility generated by a particular action or decision. The idea is to maximize pleasure and minimize pain, with the ultimate goal of promoting the greatest happiness for the greatest number of individuals.

Overall, hedonistic calculus provides a systematic approach to assess and compare the consequences of actions based on their impact on pleasure and pain. It serves as a framework for utilitarians to make ethical judgments and decisions by considering the net balance of happiness produced by different choices.
