Hi there!

Solve for x
x + 5y = 15

Subtract 5y from both sides.
x = 15 - 5y

----------------------


Solve for y
x + 5y = 15

Subtract x from both sides.
5y = 15 - x

Divide both sides by 5.
y = 3 - \frac{1}{5} x

Answer:

Step-by-step explanation:

g(-4) = 4   ,  x < -2

g(-2) = (x - 1)²     ; -2≤x< 1

        = (-2-1)²

         = (-3)²

g(-2) = 9

g(0) = (x -1)²      ;  -2 ≤ x < 1

      = (0 -1)²

       = (-1)²

       = 1

Find the indicated IQ score. The graph to the right depicts IQ scores of​ adults, and those scores are normally distributed with
larisa86 [58]

Based on the mean, standard deviation, and the graph, the indicated IQ score would be 115.

<h3>What is the indicated IQ score?</h3>

First, find the z value:

P(Z<z) = 1 - tail value

= 1 - 0.1587

= 0.8413

According to the z-value, this gives a value of:

z = 1

The indicated IQ score is:

= mean + z value z standard deviation

= 100 + 1 x 15

= 115
