The local ice cream parlor sells an average of 11 milkshakes a day for $3.99
Greeley [361]

In a week, the parlor would make about $300 from milkshakes

The total amount the ice cream parlor makes in a week is dependent is the product of the number of days in a week , the number of milkshakes sold in a day and the price of a milkshake.

Total amount = number of milkshakes sold in a week x price of a milkshake

There are 7 days in a week, in a week the parlor would sell : 11 x 7 = 77 milkshakes

price of a milkshake = $3.99

77 x $3.99 = $307.23

A survey of 32 different gas stations in Texas found the average price of gasoline to be $3.19 a gallon with a sample standard d
Leni [432]

Answer:

The value of test statistic is -4.1247

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = $3.26 a gallon

Sample mean, \bar{x} = $3.19 a gallon

Sample size, n = 32

Sample standard deviation, σ = $0.096

First, we design the null and the alternate hypothesis

H_{0}: \mu = 3.26\text{ dollars a gallon}\\H_A: \mu < 3.26\text{ dollars a gallon}

We use one-tailed t test to perform this hypothesis.

Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

t_{stat} = \displaystyle\frac{3.19 - 3.26}{\frac{0.096}{\sqrt{32}} } = -4.1247

Thus, the value of test statistic is -4.1247

BRAINLIEST ASAP! PLEASE. HELP ME :) I need help with part 2 of the question.
tino4ka555 [31]

Part 2:

-4a + 2 + 11a = 5a + 3 + 2a

~Combine like terms

7a + 2 = 7a + 3

~Subtract 2 to both sides

7a = 7a - 1

~Subtract 7a to both sides

0 = 1

Therefore, there are no solutions.

Best of Luck!

Write the area A of a square as a function of its perimeter P. ...?
Svetradugi [14.3K]
The answer is A = P²/16

The perimeter P of a square is sum of its sides s: P = s + s + s + s = 4s
The area A of a square with side s is: A = s * s  = s²

Step 1: Solve s from the formula for the perimeter.
Step 2: substitute s from the formula for the perimeter into the formula for the area.

Step 1:
P = 4s
s = P/4

Step 2:
A = s²
s = P/4
A = (P/4)²
A = P²/4²
A = P²/16
