I am not sure but I think the correct answer is c
<span>It can be assumed that the sample mean would would be approximately normal by the mean distribution theorem. The mean distribution theorem states that a large enough sample size will have a distribution and mean approximately the same as the population mean. A sample of 250, half the size of 500, is of sufficient size to assume the distribution mean will be approximately normal like the population mean.</span>

Answer:
The number of car washed per club is:
The art club = 533 cars
The music club = 633 cars
The drama club = 414 cars
Step-by-step explanation:
The art club, music club, and drama club at Glendale High School raised money last summer by washing cars.•
For the art club
The art club raised about $3,200 and charged $6 per car.•
$6 = 1 car
$3200 = x
6x = 3200
x = 3200/6
x = 533.33333333 cars
Approximately = 533 cars
The music club earned approximately $3,800, charging $8 for each car
$8 = 1 car
$3800 = x
8x = 3800
x = 3800/8
x = 633.33333333 cars
Approximately = 633 cars
The drama club took in nearly $2,900, at a cost per car of $7.
$7= 1 car
$2900 = x
7x = 2900
x = 2900/7
x = 414.28571429 cars
Approximately = 414 cars
The number of car washed per club is:
The art club = 533 cars
The music club = 633 cars
The drama club = 414 cars
Answer:
The speed of the pass that clocked is 30.31 yards per seconds
Step-by-step explanation:
Given as :
The speed of the pass = 62 miles per hour
Let The speed in yards per second = x yps
So, ∵ The speed = 62 miles per hour
Or, The speed = 
or, The speed = 
∵ In 1 hour = 3600 seconds
So, The speed = 0.0172 miles per second
Now, Again
Since 1 mile = 1760 yards
So, 62 miles = 1760 × 62 = 109,120 yards
∴ The speed in yard per second = 
I.e The speed in yards per second = 30.31 yards per seconds
Hence The speed of the pass that clocked is 30.31 yards per seconds Answer
