The greatest common factor of 7 and 10 is 1 because no number, not the smallest number possible,2, can go into both, it can go into 10, but not 7.

The answer is 1.
7 x 1 = 7
and 10 x 1 = 10
They don't have other factors in common besides 1.

Marizza181 [45]

Answer:

0.0803 = 8.03% probability that the number who have a high school degree as their highest educational level is exactly 32.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they have a high school degree as their highest educational level, or they do not. The probability of an adult having it is independent of any other adult. This means that the binomial probability distribution is used 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.

30.4% of U.S. adults 25 years old or older have a high school degree as their highest educational level.

This means that $p = 0.304$

100 such adults

This means that $n = 100$

Determine the probability that the number who have a high school degree as their highest educational level is a. Exactly 32

This is P(X = 32).

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

$P(X = 32) = C_{100,32}.(0.304)^{32}.(0.696)^{68} = 0.0803$

0.0803 = 8.03% probability that the number who have a high school degree as their highest educational level is exactly 32.

What is the value of this expression when n approaches infinity?

topjm [15]

ANSWER

C. 35

EXPLANATION

The given expression is:

$15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} }$

As

$n \to \: \infty$

$\frac{k}{n} \to0$

where k is a constant.

This implies that,

$15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} } = 15 - 35 - 0 + 55 + 0+ 0 =35$

The correct answer is C

Assume y varies directly with x. when y=2 2/3 when x=1/4, what is y when x=1 1/8? NEED HELP QUICK!!

snow_tiger [21]

3y=8x

Explanation:

If y varies directly with x then

y=c⋅x for some constant of variation c

If (x,y)=(14,23) is a solution to this equation, then

23=c⋅14

→c=23⋅41=83

So

y=83x

or (clearing the fraction)

3y=8x
