Cost of a bottle of juice is $ 1.62

Equation for determining the cost of juice is 1.56 + 20x = 33.96

Given,

The cost of a bag of chips = $ 1.56

Number of juice bottles bought by Sarah = 20 pack

Total cost before tax = $ 33.96

Cost of one bottle of juice = x

We have to find x:

Then the equation will be:

1.56 + 20x = 33.96

Add -1.56 to both sides:

1.56 + 20x - 1.56 = 33.96 - 1.56

We get,

20x = 32.4

Now find x,

x = 32.4 / 20

Then,

x = 1.62

That is, the equation for finding the cost of a bottle of juice is 1.56 + 20x = 33.96.

The cost of one bottle of juice is $1,62

The expression to illustrate the information when Maria bought the tickets is C = (5 × $20) + ($2 × 5) and the total amount paid is $110.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. A mathematical expression shows the value of something by combining numbers, variables, and operators. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing. For instance, the mathematical equation for "4 added to 2" will be 2+4.

From the information, Maria bought 5 tickets for $20 each. Each ticket had a $2 fee.

The expression that can be used to illustrate this will be:

C = (5 × $20) + ($2 × 5)

where C = Total cost

C = $100 + $10

C = $110

Therefore the expression to illustrate the information when Maria bought the tickets is C = (5 × $20) + ($2 × 5) and the total amount paid is $110.

Step-by-step explanation:

Monthly Payment Formula

[tex]\sf PMT=\dfrac{Pi\left(1+i\right)^n}{\left(1+i\right)^n-1}[/tex]

where:

Given:

Down payment = $0

⇒ P = $39,950

[tex]\implies \sf PMT=\dfrac{39950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]

[tex]\implies \sf PMT = 668.3892086[/tex]

Therefore, the monthly payment is $668.39.

Down payment = $2,000

⇒ P = $39,950 - $2,000 = $37,950

[tex]\implies \sf PMT=\dfrac{37950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]

[tex]\implies \sf PMT = 634.9279215[/tex]

Therefore, the monthly payment is $634.93.

Down payment = $3,000

⇒ P = $39,950 - $3,000 = $36,950

[tex]\implies \sf PMT=\dfrac{36950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]

[tex]\implies \sf PMT = 618.197278[/tex]

Therefore, the monthly payment is $618.20.

Down payment = $5,000

⇒ P = $39,950 - $5,000 = $34,950

[tex]\implies \sf PMT=\dfrac{34950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]

[tex]\implies \sf PMT = 584.735991[/tex]

Therefore, the monthly payment is $584.74.

Answer:

y = - [tex]\frac{\sqrt{111} }{20}[/tex]

Step-by-step explanation:

using Pythagoras' identity in the right triangle formed by the radius 1 and the given point, then

y² + (- [tex]\frac{17}{20}[/tex] )² = 1²

y² + [tex]\frac{289}{400}[/tex] = 1

y² = 1 - [tex]\frac{289}{400}[/tex] = [tex]\frac{111}{400}[/tex] ( take square root of both sides )

y = ± [tex]\sqrt{\frac{111}{400} }[/tex] = ± [tex]\frac{\sqrt{111} }{20}[/tex]

since the point is in the third quadrant then y < 0

y = - [tex]\frac{\sqrt{111} }{20}[/tex]

The amount of Alfalfa hay is 385.71 lbs

The amount of Clover is 572.45 lbs.

A percentage is a number or ratio that can be expressed as a fraction of 100.

We have,

Alfalfa hay = 18 % CP

Clover = 4% CP.

The total amount of ration is 600 lbs of a 13% CP.

Let x pounds of alfalfa hay have been used.

The amount of clover will be 600 - x lbs.

The CP amount in 600 lbs mixture will be equal to the sum of CP amounts in x lbs alfalfa and (600 - x) lbs clover.

13% of 600 = 18% of x + 4% of (600 - x)

We need to find x.

13/100 x 600 = 18/100 x (x) + 4/100 x (600 -x)

78 = 18x / 100 + 24 - 4x/100

78 - 24 = 18x/100 - 4x/100

54 = 14x / 100

14x = 54 x 100

x = 5400/14

x = 385.71 lbs

Thus,

The amount of Alfalfa hay= 385.71 lbs

The amount of Clover = 600 - 385.71 = 572.45 lbs.

The volume of the shed ordered by Lorie to hold her gardening supplies is (option a) 1423.5 cubic ft.

Given,

Lorie ordered a shed to hold her gardening supplies.

The length of the shed, l = 18.25 feet

The width of the shed, w = 15 feet

The height of the shed, h = 5 1/5 feet = 26/5 = 5.2 feet

We have to determine the volume of the shed:

From the given data we can assume that the shed is like a cuboid. So to determine the volume, we can use the cuboidal formula.

That is,

Volume = length × width × height

V = l × w × h

V = 18.25 × 15 × 5.2

V = 1423.5 feet

The probability that a person chosen at random uses both internet connections is 1/9

Total number of people = 27

Number of people who use ADSL lines = 16

Number of people who use wireless internet = 15

Number of people who use neither of the two = 3

Let the number of people who use only ADSL lines and wireless internet be denoted by A and B respectively.

Then A + B + A∩B + 3 must be equal to 27

A + B + A∩B = 24

further, we can see that

B + 16 = 24

B = 8

Also, (B + A∩B) = 15

Considering the definition of probability and its properties:

Probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.

The probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

P(A)= number of favorable cases÷ number of total cases

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

The intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.

A complementary event, also called an opposite event, is made up of the inverse of the results of another event.

The probability of occurrence of the complementary event A' will be 1 minus the probability of occurrence of A:

P(A´)= 1- P(A)

The conditional probability P(A|B) is the probability that an event A occurs, knowing that another event B also occurs. That is, it is the probability that event A occurs if event B has occurred. It is defined as:

P(A|B) = P(A∩B)÷ P(B)

In first place, let's define the following events:

You know:

The probability that a student is a freshman or a mathematics mayor is:

P [(F∪M)']= 1- P(F∪M)

7/51= 1 - P(F∪M)

7/51 - 1= -P(F∪M)

-44/51= -P(F∪M)

44/51= P(F∪M)

So, the probability that the student is both a freshman and a mathematics major is calculated as:

P(F∪M)= P(F) + P(M) -P(F∩M)

44/51= 23/51 + 30/51 - P(F∩M)

44/51- 23/51 - 30/51= - P(F∩M)

-3/17= - P(F∩M)

3/17= P(F∩M)

Finally, the probability that the student is both a freshman and a mathematics major is 3/17.

The probability that a student is a mathematics major, knowing that he is also a freshman, is calculated as:

P(M|F) = P(M∩F)÷ P(M)

So:

P(M|F) = 3/17÷ 30/51

P(M|F) = 3/10

Finally, given that the student selected is a freshman, what is the probability that he is also a mathematics major is 3/10.
