Thec at 95% is : 738.55 [tex]\leq N\leq[/tex] 759.45
We have the following information available from the question is:
A random sample of 36 drivers use on average 749 gallons of gasoline per year
The standard deviation of the population is 32 gallons.
We have to find the 95% confidence interval.
Now, According to the question:
x(bar) = 749
[tex]\sigma =32[/tex] gallon
n = 36
Confidence interval = 95%
Interval will be:
x(bar) - EBM [tex]\leq N\leq[/tex] x(bar) + EBM
where, EBM z [tex]\frac{\sigma}{\sqrt{n} }[/tex]
z = 1.'96 (For 95%)
x(bar ) - z [tex]\frac{\sigma}{\sqrt{n} }[/tex] [tex]\leq N\leq[/tex] x(bar) + z [tex]\frac{\sigma}{\sqrt{n} }[/tex]
[tex]749 - 1.96[/tex] [tex](\frac{32}{\sqrt{36} } )\leq N\leq 749+1.96(\frac{32}{\sqrt{36} } )[/tex]
749 - 10.453 [tex]\leq N\leq[/tex] 749 + 10.453
738.55 [tex]\leq N\leq[/tex] 759.45

Ms. Ponse is saving for a new iPhone. She has $150 saved and will be saving $50 per month. If the phone costs $799, how many months will it take her to save enough money?
Answer:
It would take Ms. Ponse 13 months to save up for the phone.
Step-by-step explanation:
If Ms. Ponse already has $150, then that would be the y-intercept (b) in the equation.
So, our equation so far is y = mx + 150
And since Ms. Ponse saves $50 per month, that would be the slope (m).
Now our equation would be y = 50x + 150
And we need to make our y equal to $799, since that's the goal for how much we need Ms. Ponse to save up.
799 = 50x + 150
We now need to solve for x.
x = # of months
799 = 50x + 150
- 150 - 150
799 - 150 = 50x
/50 /50
12.98 = x
And it's safe to assume that 12.98 isn't actually a number of a month, so we have to round up, meaning that it will take Ms. Ponse 13 months to buy the new iPhone.

A zucchini plant in Darnell’s garden was 13 centimeters tall when it was first planted. Since then, it has grown approximately 0.6 centimeter per day.
a. Write a rule to describe the function.
b. After how many days will the zucchini plant be 0.208 meter tall?
h(d) = 13d + 0.6; 1.6 days
h(d) = [tex]\frac{d}{0.6}[/tex]+13; 5 days
h(d) = 0.6d + 13; 13 days
h(d) = 0.6d; 35 days

Given:
The inequality is
[tex]x+19\leq 23[/tex]
To find:
The value of x and then graph on the number line.
Solution:
We have,
[tex]x+19\leq 23[/tex]
Subtracting 19 from both sides, we get
[tex]x+19-19\leq 23-19[/tex]
[tex]x\leq 4[/tex]
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.

The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. Which measurement is closest to the area of the head of this nail in square millimeters?
Answer: [tex]\boxed{\ 28.26}[/tex]
My step-by-step explanation:
We would use the formula πr2 (pi x radius x radius)2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2
And so we find: 6mm÷2=3mm3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:
πr2= 3.14 x 3 x 3= 28.26mm2Hope this helps you!
Which inequality is true when x=7?
A. x + 6 ≥ 18
B. x – 6 > 18
C. 11 + x < 18
D. 11 – x ≤ 18
Answer:
d
Step-by-step explanation:
when you plug in 7 where all the xs are, the only one that is true is d because 11-7 IS less than 18, but all the other ones are wrong.
Find the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.
Answer:
Step-by-step explanation:
The distance between two points is
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(8-3)^2+(2-8)^2
d^2=5^2+(-6)^2
d^2=25+36
d^2=61
d=7.8 (rounded to nearest tenth)

Matthew walks 5/8 mile to the bus stop each morning. How far will he walk in 5 days.
Given:
Matthew walks 5/8 mile to the bus stop each morning.
To find:
How far will he walk in 5 days.
Solution:
According to the given information,
Distance covered by Matthew in 1 day (morning) [tex]=\dfrac{5}{8}[/tex] mile
Using this, we get
Distance covered by Matthew in 5 days (morning) [tex]=5\times \dfrac{5}{8}[/tex] mile
[tex]=\dfrac{25}{8}[/tex] mile
Therefore, we will walk [tex]\dfrac{25}{8}[/tex] miles in 5 days.

A study gathers data on the outside temperature during the winter, in degrees Fahrenheit, and the amount of natural gas a household consumes, in cubic feet per day. Call the temperature x and gas consumption y. The house is heated with gas, so x helps explain y. The least-squares regression line is yhat = 1344 – 19x. 1. On a day when the temperature is 20F, the regression line predicts that gas used will be about
Answer:
The answer is "964 cubic-feet".
Step-by-step explanation:
Given regression equation:
[tex]\to Y = 1344 - 19X\\\\\to X= 20 \ F[/tex]
Putting the value of x into the above equation:
[tex]\to Y = 1344-19\times20\\\\[/tex]
[tex]= 1344-380\\\\= 964 \ cubic-feet[/tex]
