Gekata [30.6K]

The value of x in the equation (x - 5)² = 25 is 10.

<h3>How to solve an equation?</h3>

(x - 5)² = 25

Take the square root of both sides

Therefore,

√(x - 5)² = √25

x - 5 = 5

add 5 to both sides

x - 5 + 5 = 5 + 5

x = 10

GenaCL600 [577]

Answer:

3

Step-by-step explanation:

Mean = (3+7+-1+1+0+5+-3+2+-1+6+5+-2)/12

= 1.833

median is middle of ordered numbers -3/-2/-1/-1/0/1/2/3/5/5/6/8/7 here between the 6th and the 7th since with even number sample, there is not a unique middle. This would be 1.5

Standard deviation = √ 123.67/12

√10.3

=3.21

the change score that is 2.2 standard deviations below the mean.

1.83 - 2.2(3.21)

= 5.232
