Molodets [167]

Answer:

Jimmy reads 0.5 hours.

Step-by-step explanation:

Given:

Number of hours read by Laura = 2 hours

Now Given:

Conner read twice as long as Laura.

So we can say that;

Number of hours read by corner will equal to 2 times Number of hours read by Laura.

framing in equation form we get;

Number of hours read by corner = $2\times 2 =4\ hours$

Also Given:

Heather read only one- forth the time that of Conner.

So we can say that;

Number of hours read by heather will be equal to $\frac{1}{4}$ times Number of hours read by Corner.

framing in equation form we get;

Number of hours read by Heather = $\frac{1}{4}\times 4 =1\ hours$

Again Given:

Jimmy read half the amount of time that heather read.

So we can say that;

Number of hours read by Jimmy will be equal to $\frac{1}{2}$ times Number of hours read by Heather.

framing in equation form we get;

Number of hours read by Jimmy = $\frac{1}{2}\times 1 =0.5\ hours$

Hence Jimmy reads 0.5 hours.

Assume that when adults with smartphones are randomly selected, 48% use them in meetings or classes. If 8 adult smartphone use

Lisa [10]

Answer:

The probability is 2.2%

Step-by-step explanation:

The probability that a randomly selected adult uses the telephone in classes is always equal to 0.48.

If x represents the number of adults selected from among the 8 that the telephone uses in classes, then x is a discrete random variable that follows a binomial distribution, with:

p = 0.48

q = 0.52

n = 8

We want to find the probability of x = 5

$P(x) = \frac{n!}{x!(n-x)!} *p ^ n *q ^{n-x}\\\\ P(x = 5) = \frac{8!}{5!(8-5)!} * 0.48 ^ 8 * 0.52 ^ 3\\\\ P(x = 5) = 0.02218$

The probability is 2.2%
