Answers

Answer 1

The volume of the display case is 2161 1/8 cubic inches.To find the volume of a rectangular prism-shaped display case, we multiply its length, width, and height.

Given that the display case is 30 1/2 inches wide, 10 1/2 inches long, and 32 1/4 inches tall, we can calculate the volume as follows:

Volume = Length * Width * Height

Using the given measurements:

Volume = 10 1/2 inches * 30 1/2 inches * 32 1/4 inches

To simplify the calculation, we can convert the mixed numbers to improper fractions:

Volume = (21/2) inches * (61/2) inches * (129/4) inches

Next, we multiply the fractions:

Volume = (21/2) * (61/2) * (129/4) = 17289/8

The resulting fraction, 17289/8, is an improper fraction. To convert it back to mixed number form:

Volume = 2161 1/8 in³.

there are 14 gods and goddesses but only 12 thrones of olympus. which two do not have thrones on olympus and why?

Answers

The twelve thrones of Olympus are occupied by the major gods and goddesses in Greek mythology, including Zeus, Hera, Poseidon, Demeter, Athena, Apollo, Artemis, Ares, Aphrodite, Hephaestus, Hermes, and Dionysus. However, there are two gods who are not given a place on the throne - Hades and Hestia.

Hades, the god of the underworld, is not included in the twelve thrones because he rules over the dead in the underworld. As a result, he does not need a place on Olympus. Hestia, the goddess of the hearth, voluntarily gave up her seat to Dionysus, as she preferred to live a peaceful and uneventful life on earth. She is regarded as one of the "lesser" gods but still holds great importance in Greek mythology, as she is responsible for the protection of the home and family.

Overall, while the 14 gods and goddesses play important roles in Greek mythology, only twelve are given seats on Olympus. Hades and Hestia have their own roles to play and, for different reasons, do not have a place on the thrones.

the frequency of people with red hair (a recessive trait) in population a is 49% and is 25% in population b. a long-term famine in population a causes a number of people in population a to migrate to population b, where they mate randomly with members of population by. geneticists estimate that in each generation, after migration, 10% of people in population b consist of population a emigrants. what will be the frequency of individuals with red hair in population b after 10 generations of migration?

Answers

So the frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%.

We need to use the Hardy-Weinberg equation, which describes how the frequencies of alleles in a population will change over time.
The equation is:
p^2 + 2pq + q^2 = 1
Where:
p = frequency of one allele
q = frequency of the other allele
p^2 = frequency of homozygous dominant individuals
2pq = frequency of heterozygous individuals
q^2 = frequency of homozygous recessive individuals
In this case, the recessive trait is red hair, so we'll use q to represent the frequency of the recessive allele.
In population a, q = 0.49, so p (the frequency of the dominant allele) = 1 - q = 0.51.
In population b, q = 0.25, so p = 0.75.
After the emigrants from population a migrate to population b, the new frequency of the recessive allele in population b will be:
q' = (0.1 x 0.49) + (0.9 x 0.25) = 0.286
This is the new value of q after one generation of migration. To calculate the frequency of red-haired individuals after 10 generations, we need to use the equation:
q^10 = (0.286)^10 = 0.0002
So the frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%.
The frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%. This is based on the assumption that the emigrants from population a mate randomly with members of population b and that the population sizes remain constant over time.

The correct answer is (c) Reject the null hypothesis. There is enough evidence to oppose the car manufacturer's claim.

How to find the null hypothesis

The null hypothesis (H0) is that the true average speed is 145 mph, and the alternative hypothesis (H1) is that the average speed is not 145 mph.

Using a z-test, we can calculate the z-score as [tex](150-145)/(19 \sqrt(87)),[/tex]which is approximately 3.67.

For a two-tailed test at the 1% significance level, the critical z-scores are -2.576 and 2.576.

Since the calculated z-score is beyond this range, we can reject the null hypothesis.

Therefore, there is enough evidence to oppose the car manufacturer's claim.

16 oranges and 13 lemons cost $9.29 while 19 oranges and 6 lemons cost $9.05. a pair of equations appropriate for determining the price of each is:

Answers

Let's use x to represent the cost of one orange and y to represent the cost of one lemon. We can then set up a system of two equations:16x + 13y = 9.29 19x + 6y = 9.05 These equations represent the total cost of buying a certain number of oranges and lemons in two different scenarios.

To understand why we need two equations, let's consider the first equation: 16x + 13y = 9.29

This equation tells us that if we buy 16 oranges and 13 lemons, the total cost will be $9.29. But we don't know the individual prices of oranges and lemons yet. That's where the second equation comes in: 19x + 6y = 9.05

This equation tells us that if we buy 19 oranges and 6 lemons, the total cost will be $9.05. Again, we don't know the individual prices yet.

By setting up a system of equations, we can solve for x and y, which represent the prices of oranges and lemons, respectively.

One way to solve this system is by elimination. We can multiply the first equation by 19 and the second equation by -16, which will allow us to eliminate y:

304x + 247y = 176.51
-304x - 96y = -144.8

Adding these two equations together gives: 151y = 31.71
Dividing both sides by 151, we get: y = 0.21
Now we can substitute this value of y into one of the original equations to solve for x. Let's use the first equation:
16x + 13(0.21) = 9.29
16x + 2.73 = 9.29
16x = 6.56
x = 0.41

So the cost of one orange is $0.41 and the cost of one lemon is $0.21.

Answers

The expected value is 0.8, variance is 0.48, and standard deviation is 0.693 with the given probability.

a. The probability of getting one success in two trials with p=0.4 is given by the binomial probability formula:

f(1) = 2C1 * (0.4)^1 * (0.6)^1 = 0.48

b. The probability of getting zero successes is:

f(0) = 2C0 * (0.4)^0 * (0.6)^2 = 0.36

c. The probability of getting two successes is:

f(2) = 2C2 * (0.4)^2 * (0.6)^0 = 0.16

d. The probability of at least one success is:

P(at least one success) = 1 - P(no success)

= 1 - f(0)

= 1 - 0.36

= 0.64

e. The expected value of a binomial distribution with n trials and probability of success p is given by:

E(X) = np

In this case, n = 2 and p = 0.4, so:

E(X) = 2 * 0.4 = 0.8

The variance of a binomial distribution is given by:

Var(X) = np(1-p)

So:

Var(X) = 2 * 0.4 * 0.6 = 0.48

The standard deviation is the square root of the variance:

SD(X) = sqrt(Var(X)) = sqrt(0.48) = 0.693.

What is the equation, in standard form, of a parabola that contains the following points (-2, 18), (0, 2), (4, 42)?

Answers

So the equation of the parabola in standard form is y = (5/4)x^2 - (7/4)x + 2.

One way to approach this problem is to use the standard form of the equation for a parabola, which is y = ax^2 + bx + c. We can set up a system of three equations using the three points given and solve for the coefficients a, b, and c.

Starting with the point (-2, 18):

18 = a(-2)^2 + b(-2) + c

18 = 4a - 2b + c

Using the point (0, 2):

2 = a(0)^2 + b(0) + c

2 = c

Using the point (4, 42):

42 = a(4)^2 + b(4) + c

42 = 16a + 4b + c

Substituting c = 2 into the second equation, we get:

2 = 2

This is always true, so it doesn't provide any additional information.

Substituting c = 2 into the first and third equations, we get:

18 = 4a - 2b + 2

42 = 16a + 4b + 2

Simplifying each equation:

9 = 2a - b

20 = 4a + b

Solving this system of equations, we get:

a = 5/4

b = -7/4

Substituting these values for a and b, and c = 2, into the standard form equation for a parabola, we get:

the international nanny association reports that in a random sample of 528 in-home child care providers (nannies), 20 work for either a nationally known, a locally known, or an internationally known celebrity (2011 international nanny association salary and benefits survey). find a 95% confidence interval for the true proportion of all nannies who work for a celebrity.

Answers

The 95% confidence interval for the true proportion of all nannies who work for a celebrity is approximately 0.0145 to 0.0613.

The confidence interval:  

In this case, we have a random sample of 528 in-home childcare providers (nannies) and we want to estimate the proportion of nannies who work for a celebrity.

To do this, we calculate the sample proportion (p-hat) by dividing the number of nannies working for a celebrity by the total sample size.

Here we have

Sample size (n) = 528

Number of nannies working for a celebrity (x) = 20

First, we calculate the sample proportion (p-hat), which is the proportion of nannies working for a celebrity in the sample:

=> p-hat = x / n = 20 / 528

Next, we calculate the standard error (SE) using the formula:

SE = √(p-hat × (1 - p-hat)) / n)

SE = √((20 / 528) × (1 - 20 / 528) / 528)

Now, we can calculate the margin of error (ME) using the critical value associated with a 95% confidence level.

Since we have a large sample size, we can use the z-value:

z-value for a 95% confidence level ≈ 1.96

ME = z-value × SE

Finally, we can calculate the confidence interval:

Confidence Interval = p-hat ± ME

Substituting the values:

Confidence Interval = [ 20 / 528) ± (1.96×√(20 / 528)×(1 - 20 / 528) / 528) ]

Simplifying:

Confidence Interval ≈ 0.0379 ± 0.0234

Therefore,

The 95% confidence interval for the true proportion of all nannies who work for a celebrity is approximately 0.0145 to 0.0613.

you collect a basketball that's worth $150. Each following year it doubles in worth from the previous year. Write a function that shows the worth,w(t), at any given time,t.

Answers

Answer:

150(2)^t

Step-by-step explanation:

The function that represents the worth, w(t), of the basketball at any given time, t, can be written as:

w(t) = 150(2)^t

where t is the number of years since the basketball was collected.

This function uses the formula for exponential growth, where the value of the basketball doubles each year. The initial value of the basketball is $150, and the value is multiplied by 2 for each year that passes. Therefore, after one year, the basketball is worth $300 (2 times $150), after two years it is worth $600 (2 times $300), and so on.

By plugging in different values of t, we can calculate the worth of the basketball at any given time.

four hundred draws will be made at random with replacement from the box (a) estimate the chance that the sum of the draws will be more than 1,500. (b) estimate the chance that the ticket [3] will be drawn fewer than 90 times.

Answers

In both cases, the estimates depend on the specific characteristics of the box and the probabilities associated with each draw.

To estimate the chance that the sum of the draws will be more than 1,500, we need to know the distribution of values in the box and their probabilities. Without this information, we cannot provide a specific estimate.

(b) Similarly, to estimate the chance that the ticket [3] will be drawn fewer than 90 times, we need to know the distribution of values in the box and their probabilities. Without this information, we cannot provide a specific estimate.

Question 2

The prices vary by no more than $. The middle half of the prices vary by no more than $. The admission prices differ from the mean price by an average of $

Answers

The range is $14.

The interquartile range is $8.5.

The mean absolute deviation is $4.

What are measures of spread and central tendency in the prices?

The Data set of the admission prices are: [tex]20, 20, 16, 12, 15, 25, 11[/tex]

The range = Maximum value - Minimum value

The range = $25 - $11

The range = $14

To get interquartile range, we will calculate first and third quartiles.

Arranging data in order, we get: [tex]11, 12, 15, 16, 20, 20, 25[/tex]

The first quartile is the median of the lower half of the data which is:

= (11+12)/2

= $11.5

The third quartile (Q3) is the median of the upper half of the data which is:

(20+20)/2

= $20

IQR = Q3 - Q1

IQR = $20 - $11.5

IQR = $8.5

To find the mean absolute deviation, we will calculate the mean.

Mean = sum of values / number of values

Mean = ($11 + $12 + $15 + $16 + $20 + $20 + $25) / 7

Mean = $17

|$11 - $17| = $6

|$12 - $17| = $5

|$15 - $17| = $2

|$16 - $17| = $1

|$20 - $17| = $3

|$20 - $17| = $3

|$25 - $17| = $8

MAD = Sum of absolute deviations / Number of values

MAD = (6 + 5 + 2 + 1 + 3 + 3 + 8) / 7

Responses

x2+2x−132x2+16


−x2+2x−13x2+8


x2+2x−13x2+8


−x2+2x−132x2+16

Answers

Answer:

x2+2x−132x2+16

Step-by-step explanation:

First, let's simplify the expression by combining like terms:

x - 7x^2 + 8 - x^2 - x + 6x^2 + 8

= -7x^2 + 5x^2 - x^2 + x + 16

= -x^2 + 2x + 16

Now we need to factor the quadratic expression -x^2 + 2x + 16. We can use the quadratic formula or complete the square to find the roots, but it turns out that the expression doesn't factor nicely. However, we can rewrite it as -(x^2 - 2x - 16) and then use the quadratic formula to find the roots of the expression inside the parentheses:

x = (-(-2) ± sqrt((-2)^2 - 4(-16)))/(2(1))

x = (2 ± sqrt(68))/2

x = 1 ± 2sqrt(17)/2

x = 1 ± sqrt(17)

So we have:

-x^2 + 2x + 16 = -(x - (1 + sqrt(17)))(x - (1 - sqrt(17)))

Therefore, the expression is equal to -x^2 + 2x + 16, which corresponds to the option:

x^2 + 2x - 13 / 2x^2 + 16

Write in factored form then identify the zeros y=(x+1)^2-4

Answers

To write the given quadratic equation, y = (x + 1)^2 - 4, in factored form, we can start by expanding the equation using the square of a binomial:

y = (x + 1)(x + 1) - 4

y = (x^2 + 2x + 1) - 4

y = x^2 + 2x + 1 - 4

y = x^2 + 2x - 3

Now, to find the zeros of the equation, we set y = 0 and solve for x:

x^2 + 2x - 3 = 0 To factor this quadratic equation, we need to find two numbers whose product is -3 and whose sum is 2. The numbers that satisfy this condition are 3 and -1:

(x + 3)(x - 1) = 0

Now, setting each factor equal to zero, we can find the values of x:

x + 3 = 0  =>  x = -3

x - 1 = 0  =>  x = 1

Therefore, the factored form of the equation y = (x + 1)^2 - 4 is (x + 3)(x - 1) = 0, and the zeros of the equation are x = -3 and x = 1.

Perform the following area application
If 600 bricks measuring 12" by 18" are required to build a wall 10 ft. high (one brick thick), how long is the wall?
_________ft.

Answers

The first step is to calculate the total area of 600 bricks.

Area of one brick = 12 inches x 18 inches = 216 square inches

Area of 600 bricks = 600 x 216 = 129,600 square inches

Next, we need to convert the height of the wall from feet to inches since the area of the bricks is in square inches.

10 feet = 120 inches

Now, we can divide the total area of the bricks by the height of the wall to find the length of the wall.

Length of the wall = Area of 600 bricks / Height of the wall
Length of the wall = 129,600 square inches / 120 inches
Length of the wall = 1080 inches

Finally, we can convert the length of the wall back to feet by dividing by 12 since there are 12 inches in a foot.

Length of the wall = 1080 inches / 12 inches/foot
Length of the wall = 90 feet

Therefore, the length of the wall is 90 feet.

To solve this problem, we need to use the formula for calculating area which is length x width. We also need to convert units from feet to inches and vice versa as necessary to ensure we are working with the same units throughout the problem.

The length of the wall is 90 feet.
