Write the equation of a line perpendicular to the line y = 2x - 3 that goes through point (4,3). Convert the line to Slope-Intercept Form.
Answer:
y=-1/2x+5
Step-by-step explanation:
a line perpendicular to a given line will have a slope that is the negative reciprocal of the given one. this means the slope of the line perpendicular to the given one would be -1/2.
How I got this: 2 as a fraction would be 2/1, so the reciprocal would be 1/2, but we want the NEGATIVE reciprocal, so we multiply the fraction by -1, which gets us -1/2.
Now we know the slope of the equation that passes through (4,3) which is perpendicular to the given line.
y=-1/2x+b
b is the y-intercept, so we use the point (4,3) and the slope we were given to find out b.
when the point's x value is 0, the y value is the y intercept.

Construct Income Statement(s) for a firm with an accounting break-even point of $1,000,000 and a degree of operating leverage of 3. Assume a corporate income tax rate of 10%. Show calculations that prove that the accounting break-even point is $1,000,000 and the DOL is 3 for your statement(s).
Answer:
The following is an income statement using the Contribution format.
...........................Income Statement for Rivieremia Corp................................
Sales ........................................................................$1,500,000
Less Variable Costs................................................($1,200,000)
Contribution Margin..............................................$300,000
Less Fixed Costs....................................................($200,000)
Operating Income .................................................$100,000
Less Tax....................................................................($10,000)
Net Income...............................................................$90,000
Tax = 10% * 100,000 = $10,000
Proving breakeven is $1,000,000.
The breakeven point for a company can be calculated by dividing the Fixed cost by the contribution margin ratio.
Contribution margin ratio = Contribution margin / Sales
= 300,000/1,500,000
= 20%
= Fixed Cost/ Contribution Margin ratio
= 200,000/20%
= $1,000,000
Degree of Operating Leverage = Contribution Margin/ Operating Income
= 300,000/100,000
= 3

A rectangular restaurant kitchen has a perimeter of 54 meters. Its area is 162 square meters. What are the dimensions of the kitchen?
Answer:
length = 18m
width = 9m
Step-by-step explanation:
a = lw
162 = lw
p = 2l + 2w
54 = 2l + 2w
27 = w + l
27 - w = l
162 = (27 - w)w
162 = -w² + 27w
-162 = w² - 27w
0 = w² - 27w + 162
0 = (w - 9)(w - 18)
9 = width
18 = length
a = (18)(9)
a = 162
27 = 18 + 9
27 = 27
Thus proves our answer.

Ms. Anguiano is enjoying a bicycle ride on a country road
that runs east to west past a haunted house. Define a
coordinate system (x-axis) so that increasing "x" means
moving east (POSITIVE). At noon, Ms. Anguiano is 6 miles
(mi) east of the haunted house. A half-hour later, she is
8 mi west of the haunted house. What is her
displacement ? HINT: EAST IS POSITIVE, WEST IS
NEGATIVE.
Answer:
The rate is 13 miles per hour
Step-by-step explanation:
* Lets explain how to solve the problem
- Jim lives three miles east of State College
- At noon, he leaves his house and begins to walk due east at a
constant speed of 2 miles per hour
- Annie lives four miles north of State College
- At noon, she leaves her house and begins to bicycle due north at a
constant speed of 8 miles per hour
- The east is perpendicular to the north
* Lets solve the problem
∵ At noon means 12 p.m
∵ They moved till 1 p.m
∵ Jim walked for 1 hour and Annie bicycled for 1 hour
∵ The rate of Jim is 2 miles per hour
∵ The rate of Annie is 8 miles per hour
- The distance = rate × time
∴ Jim walked = 2 × 1 = 2 miles
∴ Annie bicycled = 8 × 1 = 8 miles
- Lets calculate the distance of Jim from the State College till his
position at 1 p.m
∵ Jim lives three miles east of State College
∴ His distance at 1 p.m = 3 + 2 = 5 miles east
- Lats calculate the distance of Annie from the State College till her
position at 1 p.m
∵ Annie lives four miles north of State College
∴ Her distance at 1 p.m = 4 + 8 = 12 miles North
- Lets find the distance between them at 1 p.m
∵ The north ⊥ east
- Use Pythagoras Theorem to find the distance
∴ The distance = √(5² + 12)² = √(25 + 144) = √169 = 13 miles
- The rate = distance/time
∵ The distance between them is 13 miles in 1 hour
∴ The rate = 13/1 = 13 miles per hour
* The rate is 13 miles per hour

A team of scientists are conducting research on the effect of word fonts used in road signs on accident rates. Across the population, there is an average of μ = 40 accidents per year due to unclear road sign fonts, with a standard deviation of σ = 10. The distribution is approximately normal. The team believes that certain fonts are difficult to read and may cause accidents, and it wants to implement a change to road sign fonts nationwide. The team is recommending a new font to replace the old fonts in road signs. After a series of studies, the team finds that the new font decreases accidents. However, the effect size is rather small (d = - 0.2). If the change to road sign fonts is implemented and there truly is an effect, it is expected that the new average rate of accidents will be: μ = 38 (i.e., hypothesized mean of the treatment group). In other words, this change should decrease accidents by 2, on average. [50 points total]
A.) Because implementing such large-scale changes is very costly, the government wants to be sure that the investment will be impactful. For a hypothesis test, they want the α-level to be small to minimize error. It is decided that α = 0.01, and a one-tailed test will be used. [50 points]
-What type of error is minimized by setting a stricter (smaller) α-level?
-With a one-tailed hypothesis test at α = 0.01, use the unit normal table to find the zscore that marks the critical region.
B.) A sample of n = 100 people are selected to go through a road trial with new fonts in the road signs. Again, the treatment is expected to decrease accidents by 2 on average. If the researchers use a one-tailed hypothesis test with α = 0.01, what is the power of the hypothesis test? [10 points]
C.)An external consultant is worried that there may not be enough power to detect such a small effect with such a small sample size. The consultant recommends that the researchers select a sample of n = 400 people instead. With this new sample size, and assuming a one-tailed hypothesis test with α = 0.01 again, what is the power of the hypothesis test?
D.)Based on your answers in 3(b) and 3(c), calculate the probability of making a Type II error in both cases and explain what the values mean.
E.) Explain how sample size influences power. Discuss what this means in terms of the conclusions you might make in hypothesis testing. (You can use your answers in 3(b) and 3(c) as an example.)

Answer:
a. What are the units of measurement of the variable of interest?
C. Dollars
Based on the units, what type of data is this, quantitative or qualitative?
The data is quantitative
b. What can be said about the number of measurements between $1,400 and $2,600?
That at least 3/4 or 75% of the measurements are between $1,400 and $2,600.
c. What can be said about the number of measurements between $1,100 and $2,900?
That at least 8/9 of the measurements are between $1,100 and $2,900
Step-by-step explanation:
a. What are the units of measurement of the variable of interest?
C. Dollars
Based on the units, what type of data is this, quantitative or qualitative?
Since the units is in dollars, therefore the data is quantitative.
b) We solve this question using Chebyshev's theorem.
Chebyshev's theorem states that:
1) At least 3/4 of the data lies within two standard deviations of the mean. This means, the interval endpoints :
Mean ± 2Standard deviation
2) At least 8/9 of the data lies within three standard deviations of the mean. This means, the interval endpoints :
Mean ± 3Standard deviation
For the given questions:
b. What can be said about the number of measurements between $1,400 and $2,600?
Mean = $2000
Standard deviation = $300
We would apply the first rule of Chebyshev's theorem.
1) At least 3/4 of the data lies within two standard deviations of the mean. This means, the interval endpoints :
Mean ± 2Standard deviation
$2000 + 2($300)
$2000 + $600
= $2600
$2000 - 2($300)
= $2000 - $600
= $1400
For question b, the first rule of Chebyshev's theorem works.
Therefore, at least 3/4 of the measurements are between $1,400 and $2,600.
c. What can be said about the number of measurements between $1,100 and $2,900?
Mean = $2000
Standard deviation = $300
We would apply the second rule of Chebyshev's theorem.
2) At least 8/9 of the data lies within two standard deviations of the mean. This means, the interval endpoints :
Mean ± 3Standard deviation
$2000 + 3($300)
$2000 + $900
= $2900
$2000 - 3($300)
= $2000 - $900
= $1100
For question c, the second rule of Chebyshev's theorem works.
Therefore, at least 8/9 of the measurements are between $1,100 and $2,900
