The alternative and null hypotheses is given below,
Null Hypothesis, H0: μ1 - μ2 = 0
Alternative Hypothesis, Ha: μ1 - μ2 < 0
Compound Variance is given as,
sp = sqrt( s12n1+s22n2)
sp = sqrt(16973 + 112.3673)
sp = 1.9632
Test statistic of z is,
z = (x1bar - x2bar)/sp
z = (69 - 71)/1.9632
z = -1.02
P-value Approach, P=0.1539 as long as P>= 0.
As P-value >= 0.01, failing to rule out the null hypothesis.

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?
f(150) represents the average number of days houses stay on the market before being sold for $150,000.
Houses sell on the market for an average of $150,000 and stay on the market an average of 150 days before being sold.
Houses sell for an average of $150,000.
f(150) indicates houses stay on the market an average of 150 days before being sold.
Answer:
This is the average number of days the house stayed on the market before being sold for $150,000.
Step-by-step explanation:
f(p) is defined as the average number of days a house stays on the market before being sold for price p (given in $1000).
We want f(150); this means p=150. Since p is in thousands of dollars, this means the price of the house was $150,000.
This means f(150) is the average number of days the house stayed on the market before being sold for $150,000.
Answer:
The statement that best describes f(150) is D
Step-by-step explanation:
D. f(150) indicates houses stay on the market an average of 150 days before being sold.
Because houses stay on the market for 150 days before being sold.

Timothy walks from home to a mailbox. After
walking 15 min, he puts a letter in the mailbox.
Then he walks home at the same speed. The
graph shows his distance from the mailbox
as a function of time. What is his walking speed?
A 280 ft/min © 260 ft/min
B 270 ft/min
D 250 ft/min
Answer:
D. 250 feet per minute
Step-by-step explanation:
According to this question, Timothy walks at constant speed. From Physics we know that speed is the magnitude of velocity and is determined by the following definition:
[tex]v = \frac{\Delta x}{\Delta t}[/tex] (1)
Where:
[tex]\Delta x[/tex] - Distance between home and mailbox, measured in feet.
[tex]\Delta t[/tex] - Travel time, measured in minutes.
[tex]v[/tex] - Walking speed of Timothy, measured in meters per second.
The distance is represented by the vertical axis of the graph, whereas the travelling time is from the horizontal axis.
If we know that [tex]\Delta x = 3,750\,ft[/tex] and [tex]\Delta t = 15\,min[/tex], then the walking speed of Timothy is:
[tex]v = \frac{3,750\,ft}{15\,min }[/tex]
[tex]v = 250\,\frac{ft}{min}[/tex]
The walking speed of Timothy is 250 feet per minute. Hence, the right answer is D.

Peter makes $15 an hour working at the grocery store and $12 an hour babysitting. He needs to make a minimum of $325 for a new bike. Which inequality best represents the situation, where g represents the number of hours at the grocery store and b represents the number of hours babysitting?
Answer:
15g + 12b ≥ 325
Step-by-step explanation:
g represents the number of hours at the grocery store
b represents the number of hours babysitting?
We are told that he need to make a minimum of: $325 for a new bike
Minimum means at least $325
Therefore, our inequality equation that best represents the situation is:
15g + 12b ≥ 325

Answer:
42,46
Step-by-step explanation:
2n+2n+4=88
4n+4=88
4(n+1)=88
n+1=88/4
n+1=22
n=22-1
n=21
Therefore
2n=2*21=42
2n+4=2*21+4

At Superior Engraving, a trophy costs $12.50 and engraving on the trophy costs $0.40 per letter. At another store, Duluth Trophy, the same trophy costs $14.75 and engraving costs $0.25 per letter. How many letters must be engraved for the costs to be the same at both places?
Answer:
The answer is 15 words
Step-by-step explanation:
Taking the problem as a algebraic expression, we get
[tex]12.50 + 0.40x = 14.75 + 0.25x[/tex]
Now, subtracting 12.50 + 0.25x from both sides, we get
[tex]0.15x = 2.25[/tex]
Therefore,
No of words = 2.25/0.15 = 15

Answer:
[tex]y = \frac{7}{4}x - \frac{5}{4}[/tex]
Step-by-step explanation:
Equation of line K: [tex]y = \frac{-4}{7}x + 1[/tex]
m₁ = -4/7
The slope of line I = -1 / m₁ = -1÷(-4/7)
= [tex]-1 * \frac{-7}{4}[/tex]
= 7/4
( -5 , -10) ; m = 7/4
y - y1 = m(x - x1)
y - [-10] = [tex]\frac{7}{4}(x -[-5])[/tex]
y + 10 = [tex]\frac{7}{4}(x +5)\\[/tex]
y + 10 = [tex]\frac{7}{4}x+5*\frac{7}{4}\\[/tex]
[tex]y = \frac{7}{4}x + \frac{35}{4} - 10\\\\y = \frac{7}{4}x + \frac{35}{4} -\frac{40}{4}\\\\y = \frac{7}{4}x + \frac{35-40}{4}\\\\y = \frac{7}{4}x - \frac{5}{4}[/tex]

Find the values of x and y.
what was the ratio of the number of sedans to the number of suvs produced by company x last year? 1) last year, if the number of sedans produced by company x had been 8 percent greater, the number of sedans produced would have been 150 percent of the number of suvs produced by company x 2) last year, company x produced 565,000 sedans and 406,800 suvs
The ratio is 25:18.
This problem is related to the ratio and proportion.
here it's miles given that if the number of sedans produced by organisation x have been extra by using 8% then the quantity would be one hundred fifty % of the quantity of SUVs.
1) Let that the number of sedan produced be x and number of SUVs be y.
Now according to question,
[tex]x+\frac{8}{100}*x =\frac{150}{100}*y[/tex]
⇒[tex]\frac{108x}{100}=\frac{150y}{100}[/tex]
⇒[tex]\frac{x}{y} =\frac{150}{108}[/tex]
∴ x : y=25 : 18
2) Now again the ratio =[tex]\frac{565000}{406800}[/tex]
=[tex]\frac{5650}{4068}[/tex]
= [tex]\frac{25}{18}[/tex]
So, the ratio of the number of sedans to the number of SUVs is 25:18.

The company in the example on page 301 decides to increase the capacity of its large bottles from 32 fl oz to 40 fl oz. It plans to keep the ratio of capacity to cost the same. How much should the company charge for a bottle that holds 40 fl oz
Answer:
Cost of new bottle = 1.25a
Step-by-step explanation:
Given:
Volume of old bottle = 32 fl oz
Volume of new bottle = 40 fl oz
Computation:
Assume price ratio of old bottle = a
So,
Price ratio of new bottle [Compare by capacity] = [40/32]a
Cost of new bottle = 1.25a
