lianna [129]

Answer:

102 in^3.

Step-by-step explanation:

Volume of the ice cream container = 10*14*12 = 1680 in^3.

Volume of the sherbet container = 11*18^9 = 1782 in^3.

So the answer is 1782 - 1680

= 102 in^3.

Assume that when adults with smartphones are randomlyâ€‹ selected, 63â€‹% use them in meetings or classes. If 7 adult smartphone

nlexa [21]

Answer:

5.78% probability that exactly 2 of them use their smartphones in meetings or classes.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they use their smarthphone in meetings or classes, or they do not. The probability of an adult using their smartphone on meetings or classes is independent of other adults. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

63% use them in meetings or classes.

This means that $p = 0.63$

7 adult smartphone users are randomly selected

This means that $n = 7$

Find the probability that exactly 2 of them use their smartphones in meetings or classes.

This is P(X = 2).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{7,2}.(0.63)^{2}.(0.37)^{5} = 0.0578$

5.78% probability that exactly 2 of them use their smartphones in meetings or classes.

If an area of a rectangle with width x can be represented with the expression A(x)=x(14-x), what is the perimeter of the rectang

AlekseyPX

To solve for the perimeter first figure out the length and width from the formula of area for the rectangle
A = LxW
A = (14-X)•X
L = (14-X)
W = X
P = 2L + 2W
P = 2(14-X) + 2(X)
P = 28 - 2X + 2X
P = 28.
The perimeter of the rectangle is A. 28.
