Answers
Question:
For a population with a mean of μ=45 and a standard deviation of σ=10. What is the corresponding z score if it has a score of X = 44?
Answer:
[tex]z = -0.10[/tex]
Explanation:
Given
[tex]\mu = 45[/tex]
[tex]\sigma = 10[/tex]
[tex]x = 44[/tex]
Required
Calculate the z score
This is calculated as:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
So:
[tex]z = \frac{44 - 45}{10}[/tex]
[tex]z = \frac{-1}{10}[/tex]
[tex]z = -0.10[/tex]
If taxes reduce consumer and producer surplus as well as create a deadweight loss, do we need them? Explain why or why not.
Answers
Answer:
Tax revenue is the dollar amount of tax collected. For an excise (or, per unit) tax, this is quantity sold multiplied by the value of the per unit tax. Tax revenue is counted as part of total surplus. Because the tax alters the quantity that is sold in the market, it will result in a deadweight loss.The effect of the tax on the supply-demand equilibrium is to shift the quantity toward a point where the before-tax demand minus the before-tax supply is the amount of the tax. A tax increases the price a buyer pays by less than the tax. A tax causes consumer surplus and producer surplus (profit) to fall.

Suppose y is inversely proportional to x. If y = –8 when x = –2, find y when x = 32
Answers
Answer: 1/2
Explanation:
When y is inversely proportional to x. This implies that:
y = k/x
If y = –8 when x = –2, then the constant of proportionality will be;
y = k/x
-8 = k/-2
k = (-8 × -2)
k = 16
when x = 32, the value of y will be:
y = k/x
y = 16/32
y = 1/2
PLEASE HELP!!! Which sequence of transformations results in figures that are similar but not congruent
A. 90 degrees clockwise rotation, translation 5 units to the left
B. Reflection over the X axis, dilation with a a scale factor of 1/2
C. Translation 3 units down, reflection over the y axis
D. Reflection over the x-axis, translation 7 units to the left
Answers
When you get a question like this, choose the option that includes “dilation.” Dilation changes the size of the shape while keeping similarity.

This histogram shows the distribution of exam scores for a class of 33 students. which of the following is the most reasonable estimate for the median 50, 75, or 85?
Answers
Answer:
[tex]Median = 75[/tex]
Explanation:
Given
[tex]n = 33[/tex]
See attachment for histogram
Required
Determine the median
Median is calculated as:
[tex]Median = \frac{n+1}{2}th[/tex]
[tex]Median = \frac{33+1}{2}th[/tex]
[tex]Median = \frac{34}{2}th[/tex]
[tex]Median = 17th[/tex]
From the histogram, the 17th entry fall in the class: 70 - 80
In this case: the median is the average of 70 and 80
So:
[tex]Median = \frac{1}{2}(70 + 80)[/tex]
[tex]Median = \frac{1}{2}(150)[/tex]
[tex]Median = 75[/tex]
