Answer:
°F = 356
Step-by-step explanation:
°C = (°F - 32) ÷ 1.8
180 = (°F - 32) ÷ 1.8
180×1.8 = °F - 32
324 = °F - 32
°F = 324 + 32

a sprint duathlon consists of a 5 km run, a 20 km bike ride, followed by another 5 km run. the mean finish time of all participants in a recent large duathlon was 1.67 hours with a standard deviation of 0.25 hours. suppose a random sample of 30 participants was taken and the mean finishing time was found to be 1.59 hours with a standard deviation of 0.30 hours. suppose we were to make a histogram of the finishing times of all participants in the duathlon. would the histogram be a display of the population distribution, the distribution of a sample, or the sampling distribution of means?
The histogram would be a display of the population distribution. A population distribution represents the entire set of data, which in this case is the finishing times of all participants in the duathlon.
The given information about the random sample of 30 participants and its mean finishing time of 1.59 hours with a standard deviation of 0.30 hours is used to estimate the population distribution. This sample is used to make inferences about the larger population. The sampling distribution of means, on the other hand, refers to the distribution of sample means from multiple samples taken from the same population. It is used to study the variability of sample means and to make inferences about the population mean. In this case, we are not provided with multiple samples, so the histogram would not represent the sampling distribution of means.
The mean finish time of all participants in the recent large duathlon was given as 1.67 hours, and the standard deviation was 0.25 hours.
In conclusion, the histogram would be a display of the population distribution of finishing times of all participants in the duathlon.

If U And V Are Orthogonal, What Is The Magnitude Of U Times V?
If U and V are orthogonal then the magnitude of U times V will be U.V = 0 or |UxV| = uv.
U and V are two orthogonal vectors.
since the angle between them is θ = 90⁰
let u and v be the magnitudes of the vectors U and V respectively.
so first dot-product: If two non-zero vectors are orthogonal than the dot product of these vectors will be zero. Dot product of two vectors is expressed by:
U.V = uv cosθ
since these vectors are orthogonal so,
U.V = uv cos90⁰ = 0
And Cross-product: Magnitude Cross product of two orthogonal vectors will be equal to product of magnitude of these vectors.
|UxV| = uv sin θ
|UxV| = uv sin 90⁰ = uv
Therefore, U.V = 0, |UxV| = uv.

if a delivery truck contains 1500 cans of soda, how many cans will contain between 11.95 and 11.98 ounces of drink?
There will be 40 cans that contain between 11.95 and 11.98 ounces of drink.
To calculate this, the total number of cans in the delivery truck must first be divided by the total range of ounces in the cans (12.00-11.95 = 0.05). 1500/0.05 = 30000.
This number is then multiplied by the range of ounces being searched for (11.98-11.95 = 0.03). 30000*0.03 = 900.
Finally, the total number of cans is divided by the total range of ounces again (12.00-11.95 = 0.05). 900/0.05 = 40 cans.
Therefore, 40 cans contain between 11.95 and 11.98 ounces of drink.

The present value of the payments is smaller than the amount of the loan, so you will not be able to pay off the loan.
The present value of the payments refers to the current value of the future payments, considering the time value of money. In this case, the payments are made over a period of 8 months, and each payment is listed. To determine if the payments will be enough to pay off the credit card, we need to calculate the present value of these payments and compare it to the initial loan amount of $5,000.
Since the interest rate on the credit card is 1.5% per month, we need to discount each payment back to its present value. By discounting the payments, we can see the equivalent value of these payments in today's dollars. If the present value of the payments is equal to or greater than $5,000, it would be enough to pay off the loan. However, if the present value is smaller than $5,000, it means the payments will not be sufficient to pay off the loan.
In this case, without specific information about the discount rate used to calculate the present value, we cannot make an exact determination. However, based on the given information, which states that the present value of the payments is smaller than the amount of the loan, it suggests that the payments will not be enough to pay off the credit card debt.

how many gallons of paint to cover 1000 square feet
It would take approximately 2.86 gallons of standard interior latex paint to cover 1000 square feet with one coat, but this estimate may vary depending on several factors.
To determine the amount of paint needed to cover 1000 square feet, several factors must be considered, including the type of paint being used, the surface being painted, and the number of coats required.
Assuming a standard interior latex paint with a coverage rate of approximately 350 square feet per gallon, it would take approximately 2.86 gallons of paint to cover 1000 square feet with one coat. However, it is important to note that this is just an estimate and may vary depending on the specific circumstances of the project.
Factors such as the porosity and texture of the surface being painted, as well as the color and quality of the paint being used, can all affect the coverage rate. Additionally, if multiple coats are required or if there are areas that require more than one coat for complete coverage, more paint will be needed.
It is always recommended to consult with a professional painter or refer to the manufacturer's instructions for specific guidance on how much paint is needed for a particular project.

Enter your answers as a com ma separated S lf there s no answer enter E. Explain why this is so. (Select all that apply.) When every trial will be a failure, there is no variability in X. 0 when every trial will be a success, there is no variability in X. When the probability of success is the same as the probability of failure, there is no variability in X. O There are no values of p for which V(X)-0. (b) For what value of p is V(x) maximized? [Hint: Either graph V(x) as a function of p or else take a derivative.]
The value of p for which V(X) is maximized is 0.5. If the variance of a binomial random variable is equal to 0, it indicates that all trials will yield the same result. The value of p for which V(X) is maximized is 0.5.
(a) There are no p values for which V(X) = 0. When every trial is a failure, there is no variability in X. Also, when every trial is a success, there is no variability in X. When the probability of success is the same as the probability of failure, there is no variability in X. Hence, if the variance of a binomial random variable is equal to 0, it indicates that all trials will yield the same result. It implies that the probability of success is 0 or 1.
In other words, the binomial experiment is not random, and every trial has an identical outcome. As a result, there is no variability in X.
(b) The value of p for which V(X) is maximized is 0.5. The variance of a binomial distribution is given by V(X) = npq, where p is the probability of success, q is the probability of failure, and n is the number of trials. V(X) is maximized when the product npq is maximum.
Now, p + q = 1.
Therefore,
q = 1 - p.
Hence,
V(X) = np(1 - p).
Taking the derivative of V(X) to p and equating it to zero, we get
dV(X)/dp = n - 2np = 0.
Thus,
p = 0.5.
Hence, V(X) is maximized when p = 0.5.
The variance of a binomial distribution depends on the probability of success, failure, and the number of trials. If the variance of a binomial random variable is equal to 0, it indicates that all trials will yield the same result. The value of p for which V(X) is maximized is 0.5.

5. A store sells bags of pecans for $3.00, bags of walnuts for $3.50, and bags of almonds for $4.00. One day, 15
bags of nuts were sold, and $53 was earned for the sales. Two more bags of walnuts were sold than pecans.
Write a system of equations to represent this situation, define your variables, and then solve the system using
substitution. How many bags of each type of nuts were sold?
Answer:
x = 4
y = 6
z = 5
Step-by-step explanation:
Let
bags of pecans = x
bags of walnuts = y
bags of almonds = z
x + y + z = 15
3x + 3.5y + 4z = 53
Two more bags of walnuts were sold than pecans.
Walnuts = x + 2
x + y + z = 15
3x + 3.5y + 4z = 53
x + x + 2 + z = 15
3x + 3.5(x+2) + 4z = 53
2x + z = 15 - 2
3x + 3.5x + 7 + 4z = 53
2x + z = 13 (1)
6.5x + 4z = 46 (2)
Multiply (1) by 4
8x + 4z = 52 (3)
6.5x + 4z = 46 (2)
Subtract (2) from (3)
8x - 6.5x = 52 - 46
1.5x = 6
Divide both sides by 1.5
x = 4 bags
y = x + 2
= 4 + 2
= 6
y = 6 bags
Substitute the value of x into (1)
2x + z = 13 (1)
2(4) + z = 13
8 + z = 13
z = 13 - 8
= 5
z = 5 bags
Check:
x + y + z = 15
4 + 6 + 5 = 15
