Answer:

f(x²) = x² +5
(f(x))² = x² +10x +25

Step-by-step explanation:

Put the argument in place of x and evaluate the desired expression.

1. f(x²) = x² + 5 . . . . . . straight substitution for x

2. (f(x))² = (x +5)²

= (x +5)(x +5) = x(x +5) +5(x +5) = x² +5x +5x +25

(f(x))² = x² +10x +25

6. A sporting goods store receives an order of 100 baseball caps, of which 22 are green. If 1 of

Taya2010 [7]

Answer:

$\text{A. }39/50$

Step-by-step explanation:

The probability that a randomly selected cap will not be green is equal to the number of non-green caps divided by the total number of caps.

Since there are 100 caps total and 22 are green, there must be $100-22=78$ non-green caps.

Divide this by the total number of caps (100) to get the probability that a randomly selected cap will not be green:

$\frac{78}{100}$

Simplify by dividing both the numerator and denominator by 2:

$\frac{78}{100}=\boxed{39/50}$
