Lets look at the information we have:-
$7.50 per hour
How many hours to earn $116.25?
To answer this we will divide. Lets do it:-
116.25 ÷ 7.50 = 15.5
15 and a half hours.
CHECK OUR WORK:-
15.5 × 7.50 = 116.25
We were RIGHT!!
So, to earn $116.25 when getting paid $7.50 per hour you would need to work for 15 and a half hours.
Hope I helped ya!!!

Answer:
-7
Step-by-step explanation:
-20 × -7 = 140
140 × -7 = -980
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 17
For the alternative hypothesis,
µ < 17
This is a left tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 80,
Degrees of freedom, df = n - 1 = 80 - 1 = 79
t = (x - µ)/(s/√n)
Where
x = sample mean = 15.6
µ = population mean = 17
s = samples standard deviation = 4.5
t = (15.6 - 17)/(4.5/√80) = - 2.78
We would determine the p value using the t test calculator. It becomes
p = 0.0034
Since alpha, 0.05 > than the p value, 0.0043, then we would reject the null hypothesis.
The data supports the professor’s claim. The average number of hours per week spent studying for students at her college is less than 17 hours per week.
Answer:
- Area of the circle is 113.04 ft²
Step-by-step explanation:
Given:
- Diameter of circle = 12 feet
To Find:
Using formula:
<em>Where,</em>
- π = 3.14
- Diameter = 12 feet
- Radius = 12/2 = 6 feet
On substituting the required values, we get:
Hence,
- Area of the circle is<u> </u>113.04 ft²
