The National Center for Health Statistics (NCHS) reports that 70%70% of U.S. adults aged 6565 and over have ever received a pneu

Marianna [84]

Answer:

11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they received a pneumococcal vaccination, or they did not. The probability of an adult receiving a pneumococcal vaccination 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.

70% of U.S. adults aged 65 and over have ever received a pneumococcal vaccination.

This means that $p = 0.7$

20 adults

This means that $n = 20$

Determine the probability that exactly 12 members of the sample received a pneumococcal vaccination.

This is P(X = 12).

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

$P(X = 12) = C_{20,12}.(0.7)^{12}.(0.3)^{8} = 0.1144$

11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.

8-2x=-8x+14<br><br><br> answer choices <br> x=-1<br> x=-3/5<br> x=3/5<br> x=1

navik [9.2K]

Hello there!

8 - 2x = -8x + 14

Let's start by subtracting 8 to both sides

8 - 2x - 8 = -8x + 14 - 8

-2x = -8x + 6

Let's add 8x to both sides

-2x + 8x = -8x + 6 +8x

6x = 6

Divide both sides by 6

6x/6 = 6/6

x = 1

The correct answer is option D

I hope this helps!

Write an equation in slope-intercept form perpendicular to the given equation through the given point

Irina18 [472]

Answer:

y = (1/3)x - 4

Step-by-step explanation:

Any line perpendicular to the given equation y = -3x + 4 will have a slope which is the negative reciprocal of -3; that is, +1/3.

Start with the general slope-intercept form y = mx + b.

Insert the coordinates 6 and -2 into y = mx + b: -2 = (1/3)(6) + b, or

-2 = 2 + b. Thus, b = -4, and the desired equation is

y = (1/3)x - 4
