Answer:

  • 347 kids
  • 144 adults

Step-by-step explanation:

Let x represent the number of adults using the pool. Then 491 -x is the number of kids using the pool, and the total revenue is ...

  2.25x +1.25(491 -x) = 757.75

  x +613.75 = 757.75 . . . . . . . . . eliminate parentheses, collect terms

  x = 144 . . . . . . . . . . . . . . . . . . . . subtract 613.75; number of adults

  491-x = 347 . . . . . number of kids

347 kids and 144 adults used the pool.

Answer:

Mean is 83.7%

And, the standard deviation is 0.033

The computation of the mean and the standard deviation is as follows:

Let us assume the P be the sample proportion

Mean is 83.7%

And, the standard deviation is

A rectangle's width is 5 feet less than its height. If the area of the rectangle is 564 square feet, what is its length, in feet
larisa86 [58]

We can set up an equation: x * (x + 5) = 564, where x is the length of the rectangle we are trying to solve. Using the quadratic formula to solve this, we eventually come up with approximately 21.38 as a value for x. We can verify this by typing 21.38 * (21.38 + 5) into a calculator and seeing that it approximately equals 564.
