Assume that when adults with smartphones are randomly​ selected, 46​% use them in meetings or classes. If 9 adult smartphone use
MArishka [77]

Answer:

0.2027 is the probability that exactly 3 out of 9 adults use their smartphones in meetings or classes.

Step-by-step explanation:

We are given the following information:

We treat adult using smartphones in meetings or classes as a success.

P(Adult using smartphone) = 46% = 0.46

Then the number of adults follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 9

We have to evaluate:

P(x = 3)\\\\= \binom{9}{3}(0.46)^3(1-0.46)^6\\\\= 0.2027

0.2027 is the probability that exactly 3 out of 9 adults use their smartphones in meetings or classes.

Luda [366]

Answer:

1/4 page per minute

Step-by-step explanation:

To find the unit rate, we need the amount of page she read in 1 minutes. To do this we divide the pages by the minutes. Let x equal the pages she reads per minutes.

5/20=x

we can simplify  the fraction by divide both the numerator and denominator by 5

(5/5)/(20/5)=x

Do the division
