A. Write an expression for the area of the shaded region.

tekilochka [14]

Answer:

A. $25x² - 64$

B. $(5x + 8)(5x - 8)$

Step-by-step explanation:

A. The area of the shaded region = area of the whole large square - area of the 4 smaller squares

= (5x*5x) - 4(4*4)

Area of shaded region = $25x^2 - 64$

B. The expression, $25x^2 - 64$ , is the difference of two perfect squares, 25x² and 64. Therefore, apply the rule of factoring difference of two perfect squares.

Thus, $a^2 - b^2 = (a + b)(a - b)$

Therefore, the expression of the are of the shaded region can be expressed in factored form as:

$25x^2 - 64 = (5x + 8)(5x - 8)$

Alan recorded the points he scored on the basketball court in ms2 school yard. What is the mean absolute deviation of his scores

Alecsey [184]

Answer:

The mean absolute deviation is: 7.44

Step-by-step explanation:

Given

$Scores: 98, 78, 84, 75, 91$

Required

The mean absolute deviation

First, calculate the mean

$\bar x = \frac{\sum x}{n}$

$\bar x = \frac{98+78+84+75+91}{5}$

$\bar x = \frac{426}{5}$

$\bar x = 85.2$

The mean absolute deviation (M) is:

$M = \frac{1}{n}\sum|x - \bar x|$

So, we have:

$M = \frac{1}{5}(|98 - 85.2|+|78 - 85.2|+|84 - 85.2|+|75 - 85.2|+|91 - 85.2|)$

$M = \frac{1}{5}(|12.8|+|-7.2|+|-1.2|+|-10.2|+|5.8|)$

Remove absolute brackets

$M = \frac{1}{5}(12.8+7.2+1.2+10.2+5.8)$

$M = \frac{1}{5}*37.2$

$M = 7.44$
