Answers
The answer to your question is that the mean of the sampling distribution of the proportion is equal to the proportion of factorization the population, which is 0.95 in this case.
when we take a random sample from a population, the proportion of individuals with the characteristic of interest in the sample may not be exactly the same as the proportion in the overall population. However, if we take many random samples from the population and calculate the proportion of individuals with the characteristic in each sample, the distribution of those sample proportions will follow a normal distribution with a mean equal to the population proportion and a standard deviation determined by the sample size.
Therefore, in this case, since the proportion of the population with the characteristic is 0.95, the mean of the sampling distribution of the proportion will also be 0.95. This means that if we take many random samples from the population and calculate the proportion of individuals with the characteristic in each sample, the average of those proportions will be very close to 0.95.

The two linear equations are:
1) y = -x + 5
2) y = (-1/2)*x - 1
How to get the linear equations?Remember that two linear equations are parallel if and only if have the same slope and different y-intercept.
So to find a linear equation:
y = m*x + b
Parallel to:
x + y = 4
y = -x + 4
The slope needs to be m = -1 and the y-intercept b ≠ 4
So our line will be:
y = -x + b
To find the value of b, we use the fact that this line passes through (2, 3), replacing the values of the point in the line we get:
3 = -2 + b
3 + 2 = b
5 = b
The linear equation is y = -x + 5
For the second case, we want to find a line perpendicular to:
2x - y = 5
y = 2x - 5
Two lines are perpendicular if the product of the slopes is -1, then:
m*2 = -1
m = -1/2
So the perpendicular line is something like:
y = (-1/2)*x + b
To find the value of b we use the fact that this line needs to pass through (6, -4)
Replacing these values we get
-4 = (-1/2)*6 + b
-4 = -3 + b
-4 + 3 =b
-1 = b
The line is:
y = (-1/2)*x - 1

an investment strategy has an expected return of 14 percent and a standard deviation of 8 percent. assume investment returns are bell shaped
Answers
An investment strategy with an expected return of 14 percent and a standard deviation of 8 percent has the potential for higher returns, but also comes with a higher level of risk. It is important to carefully consider the trade-off between risk and return before making an investment decision.
An investment strategy with an expected return of 14 percent and a standard deviation of 8 percent means that the investment has a higher potential for return, but also a higher risk.
The standard deviation is a measure of the variation or dispersion of a set of data values. In this case, the standard deviation of 8 percent indicates the degree of variation in the investment returns. A higher standard deviation means that the investment returns are more spread out and there is a higher chance of extreme values, both positive and negative.
In terms of investment strategy, it is important to consider the trade-off between risk and return. While a higher expected return is desirable, it often comes with a higher level of risk. Therefore, it is important to carefully consider the standard deviation and the potential risks associated with an investment before making a decision.
In conclusion, an investment strategy with an expected return of 14 percent and a standard deviation of 8 percent has the potential for higher returns, but also comes with a higher level of risk. It is important to carefully consider the trade-off between risk and return before making an investment decision.

The width of bolts of fabric is normally distributed with mean 952 mm (millimeters) and standard deviation 10 mrm (a) What is the probability that a randomly chosen bolt has a width between 941 and 957 mm? (Round your answer to four decimal places.) (b) What is the appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8749? (Round your answer to two decimal places.)
Answers
a. Using the calculated z-score, the probability that a randomly chosen bolt has a width between 941 and 957 mm is approximately 0.5558.
b. The appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8749 is approximately 963.5 mm.
What is the probability that a randomly chosen bolt has a width between 941 and 957mm?(a) To find the probability that a randomly chosen bolt has a width between 941 and 957 mm, we can use the z-score formula and the standard normal distribution.
First, let's calculate the z-scores for the given values using the formula:
z = (x - μ) / σ
where:
x is the value (941 or 957)μ is the mean (952)σ is the standard deviation (10)For x = 941:
z₁ = (941 - 952) / 10 = -1.1
For x = 957:
z₂ = (957 - 952) / 10 = 0.5
Next, we need to find the probabilities corresponding to these z-scores using a standard normal distribution table or a calculator.
Using the standard normal distribution table, we find:
P(z < -1.1) ≈ 0.135
P(z < 0.5) ≈ 0.691
Since we want the probability of the width falling between 941 and 957, we subtract the two probabilities:
P(941 < x < 957) = P(-1.1 < z < 0.5) = P(z < 0.5) - P(z < -1.1) ≈ 0.691 - 0.135 = 0.5558
Therefore, the probability that a randomly chosen bolt has a width between 941 and 957 mm is approximately 0.5558.
(b) To find the appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8749, we need to find the z-score corresponding to this probability.
Using a standard normal distribution table or calculator, we find the z-score corresponding to a cumulative probability of 0.8749 is approximately 1.15.
Now, we can use the z-score formula to find the value of C:
z = (x - μ) / σ
Substituting the known values:
1.15 = (C - 952) / 10
Solving for C:
C - 952 = 1.15 * 10
C - 952 = 11.5
C ≈ 963.5
Therefore, the appropriate value for C such that a randomly chosen bolt has a width less than C with probability 0.8749 is approximately 963.5 mm.

If 3x+2y=48 and 2x+3y=12, then the value of x-2y, to the nearest tenth, is..
Answers
9x + 6y = 144
4x + 6y = 24
-----------------
5x = 120
Dividing both sides by 5, we get:
x = 24
Substituting this value of x into either of the original equations, we can solve for y:
3x + 2y = 48
3(24) + 2y = 48
72 + 2y = 48
2y = -24
y = -12
Therefore, x - 2y = 24 - 2(-12) = 24 + 24 = 48.
Rounding to the nearest tenth, we get:
x - 2y = 48.0.

When the pile is 22 feet high, the height of the pile changes to 20/1089π.
Given (dV)/(dt) = 20, h = 22 feet , dh /dt =?
The volume of cone is V = 1/3 * pi * r ^ 2 * h
d=3h
2r = 3h
r = (3h)/2
V = 1/3 * pi * r ^ 2 * h
= 1/3 * pi * ((3h)/2) ^ 2 * h
= 1/3 * pi((9 * H ^ 2 )/4) * h
= (9pi)/12 * h ^ 3
Differentiate w.r.to t
(dV)/(dt) = (3pi)/4 * (3h * h^ 2) * (dh)/(dt)
(dV)/(dt) = (9pi)/4 * (h ^ 2) * (dh)/(dt)
(dV)/(dt)=20, h=22 feet
20 = (9pi)/4 * (22 ^ 2) * (dh)/(dt)
(dh)/(dt) = 80/ (9pi * (22^ 2))
