Answer:

-1.99, 1.99

Step-by-step explanation:

Use a table to find the z-scores.

For the first z-score:

P(x < z) = 0.0233

z = -1.99

For the second z-score:

P(x > z) = 0.0233

P(x < z) = 1 − 0.0233 = 0.9767

z = 1.99

The rectangle below has an area of 81-x^2 square meters and a width of 9-x meters. What expression represents the length of the
oksian1 [2.3K]

For this case we have that by definition, the area of a rectangle is given by:

A = w * l

Where:

w: Is the width of the rectangle

l: is the length of the rectangle

According to the data of the statement we have:

A = 81-x ^ 2\\w = 9-x

So, the length is given by:

l = \frac {A} {w}\\l = \frac {81-x ^ 2} {9-x}

We factor the numerator:

l = \frac {(9 + x) (9-x)} {9-x}

We simplify:

l = 9 + x

So, the length is 9 + x

Answer:

9 + x
