At this point, the vector "intvector" will contain all of the integers read from input minus five.
int x = 0;
vector<int> intvector;
while (x != 0)
{
cin >> x;
intvector.push_back(x - 5);
}
First, we create a variable to store the integer from input, "x", and a vector to store the integers minus five, "intvector". Then, we create a while loop that runs until the value of "x" is equal to zero. Inside the loop, we read an integer from input and store the value in "x". Then, we subtract five from "x" and add the resulting value to the vector "intvector". This loop will run until the value of "x" is equal to zero. At this point, the vector "intvector" will contain all of the integers read from input minus five.

A given exam has a normal distribution with a mean of 70 and a standard deviation of 10. A sample of size 25 is selected. What percentage of the time would you expect the mean of this sample size to be greater than 68? %
The percent of the time you would expect the mean of the sample size of 25 to fall between 66 and 74 is 68.27%, to be less than 70 is 50%, and to be greater than 68 is 84.13%.
a. If a population has a mean of 100 and a standard deviation of 20, then the mean of the sampling distribution of a sample size of n=252 will be 100. This is because the sample means of a sampling distribution will always be equal to the population mean.
b. The standard deviation of the sampling distribution of a sample size of n=25 is 4. This is calculated using the formula: σx = σ/√n, where σ is the population standard deviation (20) and n is the sample size (25).
c. The percentage of the time you would expect the mean of the sample size to fall between 66 and 74 is 68.27%. This is calculated using the Z-score formula, which is (x-μ)/σ, where x is the upper limit (74), μ is the population mean (70), and σ is the population standard deviation (10). The Z-score for the upper limit is (74-70)/10=0.4. We then use the standard normal table to find the area between -∞ and 0.4, which is 0.6827.
d. The percentage of the time you would expect the mean of the sample size to be less than 70 is 50%. This is because the Z-score for a mean of 70 is 0, and the area below 0 is 0.5 or 50%.
e. The percentage of the time you would expect the mean of the sample size to be greater than 68 is 84.13%. This is calculated using the Z-score formula, which is (x-μ)/σ, where x is the lower limit (68), μ is the population mean (70), and σ is the population standard deviation (10). The Z-score for the lower limit is (68-70)/10=-0.2. We then use the standard normal table to find the area between -∞ and -0.2, which is 0.8413.
The percent of the time you would expect the mean of the sample size of 25 to fall between 66 and 74 is 68.27%, to be less than 70 is 50%, and to be greater than 68 is 84.13%.

Answer:
Which tools you need to useThe measure of one of the small angles of a right triangle is 45 less than twice the measure of the other small angle. Find the measure of both angles
The measure of both angles is 45.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Right triangle:
One angle = 90
Other angles:
One = 2x - 45
Another = x
Now,
The sum of the three angles = 180
90 + x + 2x - 45 = 180
Add like terms.
90 + 3x - 45 = 180
Add 45 on both sides.
90 + 3x = 180 + 45
Subtract 90 on both sides.
3x = 225 - 90
3x = 135
Divide 3 into both sides.
x = 45
Now,
Other angles:
One = 2 x 45 - 45 = 45
Another = 45
Thus,
Both angles are 45.

4. Computing costs to rent an LCD projector. Cesar is renting an LCD projector. The rental company charges a $10 flat fee for administrative costs plus $18 per day for the projector. If Cesar
had a bill of $82, how many days did he keep the projector?
If Cesar had a bill of $82 for renting an LCD projector, he kept the projector for 4 days, based on the linear equation.
How the number of days are determined?To determine the number of days the projector, we deploy linear equation, which is in the form of y = mx + b, where m is the slope, x and y are variables, and b is the y-intercept.
The flat fee for administrative costs = $10
The variable cost per day = $18
The total bill for renting the projector = $82
The number of days = x
Linear Equation:10 + 18x = 82
18x = 72
x = 4
Check:
10 + 18x = 82
10 + 18(4) = 82
10 + 72 = 82
82 = 82
Thus, setting a linear equation, we can determine the number of days the projector was rented as 4 days.

inequalities.
y<-5/6x+2
y>1/3x+3
Shaded region is between the lines corresponding to both inequalities.
Point that satisfy both inequalities is (-6/7 , 19/7)
What is inequality?Inequalities are the mathematical expressions in which both sides are not-equal. In inequality, unlike in equations, we compare two values.
Given inequalities
y<(-5/6)x+2
equation of the line becomes
y = (-5/6)x + 2 ------(1)
y>(1/3)x+3
equation of the line becomes
y = (1/3)x + 3 --------(2)
By the inequalities
(1/3)x + 3 < y < (-5/6)x + 2
shaded region should be between the lines.
Solving equation 1 and 2
(-5/6)x + 2 = (1/3)x + 3
(-5/6)x - (1/3)x = 3 - 2
(-5 - 2)x/6 = 1
-7x = 6
x = -6/7
Putting value of x in equation 2
y = (1/3)(-6/7) + 3
y = -2/7 + 3
y = (-2 + 21)/7
y = 19/7
Point is (-6/7 , 19/7)

An aerospace engineering student performs an experiment in a wind tunnel to determine the lift coefficient of an airfoil. The student takes 61 measurements of the vertical force using a force balance, yielding a sample mean value of 44.20 N and a sample variance of 4.00 N^2. Determine (a) the percent probability that an additional measurement will be between 45.56 N and 48.20 N, (b) the range (in N) over which the true mean value will be, assuming 90 % confidence, and (c) the range (in N^2) over which the true variance will be assuming 90 % confidence.
The mean of these five values is 9.6. This means that the average value of the five numbers is 9.6.
The formula for calculating the mean is:
Mean = (Sum of all values) / (Number of values)
For example, if you had the following numbers: 4, 8, 10, 12, and 15, you would calculate the mean by adding the values together and then dividing by the number of values:
Mean = (4 + 8 + 10 + 12 + 15) / 5 = 9.6

A man is disabled in an accident and wants to receive an insurance payment that will provide him with $2400 at the
end of each month for 20 years. If the payment can be placed in an account that pays 6% compounded monthly, what
size payment should he seek?
He should seek a payment of $
(Simplify your answer. Round to the nearest cent as needed.)
The man should seek a payment of $725.08
How to determine the size paymentThe amount of money he wants to receive can be calculated using the formula for compound interest:
A = P * (1 + r/n)^(nt)
where A = $2400 ---- final amount
P = principal
r = 6%, -- interest rate
n = 12 --- number of times the interest is compounded
t = 20, number of years (20).
So, we have
2400 = P * (1 + 6%/12)^(12 * 20)
This gives
P = 2400/3.310

Which best describes the solution set for the inequality below?
3x + 7 ≤4x-8 or-2x + 3≥1
Ox≤1or x ≥ 15
Ox≥1 orx≤ 15
Ox≥1
Ox≤ 15
The solution for the given inequalities is x≥15 or x≤1. Therefore, option A is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequalities are 3x + 7 ≤ 4x-8 or-2x + 3≥1.
Here, 3x + 7 ≤ 4x-8
Subtract 3x on both the sides of an inequality, we get
7 ≤ x-8
Add 8 on both the sides of an inequality, we get
15≤ x
x≥15
Here, -2x + 3≥1
Subtract 3 on both the sides of an inequality, we get
-2x≥-2
Divide -2 on both the sides of an inequality, we get
x≤1
So, x≥15 or x≤1
Therefore, option A is the correct answer.

the management of your team wants you to run descriptive statistics on the points scored by your team in the games played at your team's venue in 2013-2015. calculate descriptive statistics including the mean, median, variance, and standard deviation for points scored by your team played at home. make the following edits to the code block below:
in order to calculate the descriptive statistics for the points scored by the team at home in 2013-2015, the mean, median, variance and standard deviation must be calculated using the appropriate formulas.
Descriptive Statistics
Mean: This is a measure of the center of the distribution, calculated as the sum of all values divided by the number of values. In this case, it is the average number of points scored by the team at home in 2013-2015. Formula: Mean = (Sum of all values)/(Number of values).
Median: This is the middle value of the data set after it is sorted in numerical order. It is the value that separates the upper half of the data set from the lower half. In this case, it is the middle value of the points scored by the team at home in 2013-2015. Formula: Median = (Sum of the lower and upper halves of the data set)/2.
Variance: This is a measure of how spread out the data set is, calculated as the sum of the squared differences between each value and the mean, divided by the number of values. In this case, it is the variance of the points scored by the team at home in 2013-2015. Formula: Variance = (Sum of the squared differences between each value and the mean)/(Number of values).
Standard Deviation: This is a measure of how spread out the data set is, calculated as the square root of the variance. In this case, it is the standard deviation of the points scored by the team at home in 2013-2015. Formula: Standard Deviation = Square Root of Variance.
Therefore, in order to calculate the descriptive statistics for the points scored by the team at home in 2013-2015, the mean, median, variance and standard deviation must be calculated using the appropriate formulas.

You deposit $1000 into an account that pays interest compounded monthly. What interest rate do you need to double your money in 10 years? (as a percent, so change it back, write to two decimal places)
The interest rate required to double your money in 10 years with monthly compounding is approximately 133.27%.
How did we get the value?To calculate the interest rate required to double your money in 10 years with monthly compounding, you can use the formula:
rate = ( (2 * principal) / principal * (1 + n)^(t12) )^(1/t12) - 1
where
principal = $1000
t = 10 years
n = number of compounding periods per year (12 for monthly compounding)
Plugging in the values we get:
rate = ( (2 * 1000) / 1000 * (1 + 12)^(1012) )^(1/1012) - 1
rate = ( 2 * (1 + 12)^120 )^(1/120) - 1
rate = ( 2 * 169860981.54 )^(1/120) - 1
rate = 1.3327
So, the interest rate required to double your money in 10 years with monthly compounding is approximately 133.27%.
