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%

To add/subtract fractions you need to have a common denominator...

(2/2)(4n/15)+(5/5)(n/6)

8n/30+5n/30

(8n+5n)/30

13n/30

Solve for w. -22w-5)+5w-5(w+4) Simplify your answer as much as possible.

Anna [14]

Answer: −22w−25

Step-by-step explanation: Distribute:

=−22w+−5+5w+(−5)(w)+(−5)(4)

=−22w+−5+5w+−5w+−20

Combine Like Terms:

=−22w+−5+5w+−5w+−20

=(−22w+5w+−5w)+(−5+−20)

=−22w+−25

6.- Find the area under the standard normal distribution: to the left of z=-1.55.

Kisachek [45]

Answer:

$P(z$

Step-by-step explanation:

For this case we want to find this probability:

$P(z$

Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.

We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)

And we got:

$P(z$

The other possibility is use the normal standard table and we got a similar result.
