What is the mean of the data set?
andre [41]
You find the mean by adding each value then dividing the sum by the number of values there were so in this case you'd say 301 + 222 + 287 + 310 + 346 which is 1466 then divide by 5 because there are 5 values and your answer is 293.2!

I hope this helps

Martha has $180. She needs a total of $2,000 to start investing in stocks. She earns $60 per day working, of which she saves $50
DIA [1.3K]
So she earns $60 per day working, but only saves $50. To solve this equation you have to multiply $50 to each day she works. If the total has to be exactly $2,000 then you must multiply 50 x 36.4 and that equals $2,000.
Your answer should be 36.4 days.

An architect increases the radius of a circle window by 20 percent. By what percent
ale4655 [162]

Answer: 44%

Step-by-step explanation:

For a circle of radius R, the area is written as:

A = pi*R^2

Where pi = 3.14

If we increase the radius by 20%, the new radius will be:

R´ = R + 0.20*R = 1.20*R

The new area will be:

A´ = pi*(1.20*R)^2 = (1.20)^2*pi*R^2

   = 1.44*pi*R^2

And pi*R^2 = A, the original area, then_

A´ = 1.44*A = A + 0.44*A

This means that the percentage in which the area increased is:

0.44*100% = 44%
