Answer: 33.3%

Step-by-step explanation:

From the given table, the number of books which is a nonfiction paperback =23

The total number of books = 69

Then the probability that a randomly selected book is a nonfiction paperback is given by :-

$\text{P( nonfiction paperback)}=\frac{23}{69}=0.33333....$

In percent, $\text{P( nonfiction paperback)}=0.33333.....\times33.333\%\approx=33.3\%$

Hence, the probability that a randomly selected book is a nonfiction paperback is 33.3%

We have given the 2 by 2 frequency table.

The probability that a randomly selected book is a nonfiction paperback =

(Number of nonfiction paperback books) / Total number of books

= 23 / 69

= 0.3333

The percentage of nonfiction paperback books is 33.33%

Solve the equation. 8x2 – 4 = 28

Flura [38]

Hello,

Your answer would be 2, -2.

$8x^2 - 4 = 28$

$8x^2-4+4=28+4$

$8x^2 = 32$

$\frac{8x^2}{8}= \frac{32}{8} 
$

$x^2 = 4$

x = +/4

x = 2 or x = -2

2 , -2 would be the answer! :)
