Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

  1. 14=x/100*70
  2. 14/70=x/100 (Divide each side by 70)
  3. 1/5=x/100 (Simplify 14/70)
  4. 100/5=x (Multiply each side by 100 to isolate x)
  5. x=20 (Simplify 100/5)
  6. 20% (Rewrite as a percent)

hope this helps!!

If Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Then the mean of the sample is 3.75.

<h3>What is Mean?</h3>

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency.

Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week.

Fourteen people answered that they generally sell two cars; nineteen generally sell three cars; twelve generally sell four cars; nine generally sell five cars; eleven generally sell six cars.

Then the mean of the sample will be

\rm Mean = \dfrac{1}{N} \times \Sigma _{i}   \ \ x_if_i

Then the table is given below.

Then we have

\rm Mean = \dfrac{1}{65} \times (244)\\\\\\Mean = 3.7538\\\\Mean \approx 3.75

a rectangular prism has a volume of 33 3/4 cubic inches and a height of 2 and 1/4 in what is the area of the base​
tensa zangetsu [6.8K]

Answer:

The area of the base is 15 in²

Step-by-step explanation:

33 3/4 = 33.75

2 1/4 = 2.25

To calculate the area base of a rectangular prism we have to use the following formula:

a = area

v = volume  = 33.75 in³

h = height  = 2.25 in

v = a * h

we solve a

a = v / h

we replace the values that ​​we know        

a = 33.75 in³  / 2.25 in

a = 15 in²

The area of the base is 15 in²
