The mean height of the basketball players is 80.3 inches

For given question,

we have been given the list of heights, in inches, for a sample of college basketball players.

We need to find the mean height of the basketball players.

We know that, for given sample of data

mean = sum of all observations ÷ total number of observation

First we find the sum of given heights.

78 + 83 + 82 + 78 + 78 + 80+ 81 +79+ 79 +83+ 77 +78+ 84+ 82+ 80+ 80 +82+ 84+78+ 80 = 1606

Total number of observations = 20

Using the formula of mean,

⇒ mean height = 1606/20

⇒ mean height = 80.3 inches

Therefore, the mean height of the basketball players is 80.3 inches

Answer:

x^{2}-2+\frac{20}{x+7}

Step-by-step explanation:

x + 7) x³ + 7x²- 2x + 6 ( x²- 2

        <u> x³ + 7x²</u>

                     -2x + 6

                     <u>-2x - 14</u>

                           +20

Therefore, we can write the expression in the remainder quotient form as,

x^{2}-2+\frac{20}{x+7}
