Based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).
What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
When the sample size is less than 30, the formula which is used is,
[tex]\overline x\pm t.\dfrac{s}{\sqrt n}[/tex]
Here, n is the sample size, [tex]\overline x[/tex] is the sample mean, s is the standard deviation.
Economist, takes an SRS of 12 gas stations. The sample size for the given problem is 12,
[tex]n=12[/tex]
Thus, degree of freedom,
[tex]df=12-1\\df=11[/tex]
In the t table, for df 11, the value of t is 1.796.
An economist studying fuel costs wants to estimate the mean price of gasoline in her state on a certain day.
On that day, she takes an SRS of 12 gas stations and finds the sample mean price (in dollars per gallon) is,
[tex]\bar x=2.29[/tex]
With a standard deviation of
[tex]s_x=0.20[/tex]
Put the values in the above formula,

A circle has a radius of 8. Find the area of a sector of this circle that is intercepted by central angle measuring pi over 7
Answer:
14.4 square units
Step-by-step explanation:
Keep in mind that the area here is a fraction of the area of a full circle of radius 8.
(area of sector) = (fraction)(pi)(8)^2
The fraction is the given central angle (pi over 7) divided by 2pi:
pi 1
--------- * ----------- = 1/14
7 2pi
Multiply the formula (fraction)(pi)(8)^2 found above by this fraction:
area of sector = (1/14)(pi)(8)^2 = 14.4 square units

Marcello gets paid $18 per hour at his job. He takes a $4 uber ride to get to work and a $4 uber ride to get home. If he works 8 hours, what is his total profit for the day?
Answer:
$136
Step-by-step explanation:
x = per hour
y = total profit
4 + 4 = 8
Equation:
y = 18x - 8
y = 18(8) - 8
y = 144 - 8
y = 136

A pizza pan is removed at 9:00 PM from an oven whose temperature is fixed at 425°F in a room that is constant 74°F. After 5 minutes, the pizza pan is at 300 °F
A) at what time is the temperature of the pan 130°F ?
B) determine the time that needs to elapse before the pan is 180°
Answer:
9:11:48 p.m
9.8 minutes
Step-by-step explanation:
We Obtian the slope of the relation :
Slope = Rise / Run
(0, 425) ; (5, 300)
x2 = 0 ; y2 = 425 ; x1 = 5 ; y1 = 300
(425 - 300) / (0 - 5)
125 / - 5
= - 25
The intercept :
y = mx + c
425 = - 25(0) + c
425 = 0 + c
c = 425
The equation becomes :
y = - 25x + 425
Temperature at 130
130 = - 25x + 425
130 - 425 = - 25x
-295 = - 25x
x = 11.8
9:00 + 11.8 = 9:11:48 p.m
B.)
180 = - 25x + 425
180 - 425 = - 25x
-245 = - 25x
x = 9.8 minutes

Answer:
88 degrees.
Step-by-step explanation:
Since AB is equal to BC, ABC is an isosceles triangle. Therefore, the angle of B will be 180-39-39=102 degrees. As the angle of a straight line is 180 degrees, take 180-102-32=46 degrees. This 46 degrees is angle B. Since DEB is an isosceles triangle, 180-46-46=88 degrees. 88 degrees is angle E which is your answer. Edit: (Just added on the explanation.)
