I think is....
d=(−6−(14))2+(4−(−2))2+(−9−(1)^2

d=(−20)2+(6)2+(−10)2^2

d=400+36+100

d=5–√36d=536

d=23.151674

You would plug in twenty eight point nine to the q. So it would be five point one plus twenty eight point nine divided by three point four, which equals thirteen point six.

Twelve percent of U.S. residents are in their forties. Consider a group of nine U.S. residents selected at random. Find the prob

miskamm [114]

Answer:

The probability is 28 % ( approx )

Step-by-step explanation:

Since, there are only two possible outcomes in every trails ( residents are in their forties or not ),

So, this is a binomial distribution,

Binomial distribution formula,

Probability of success in x trials,

$P(x)=^nC_x p^x q^{n-x}$

Where, $^nC_x=\frac{n!}{x!(n-x)!}$

p and q are probability of success and failure respectively and n is the total number of trials.

Let X be the event of resident who are in his or her forties.

Here, p = 12% = 0.12,

⇒ q = 1 - p = 1 - 0.12 = 0.88,

n = 9,

Hence, the probability that two or three of the people in the group are in their forties = P(X=2) + P(X=3)

$^9C_2 (0.12)^2 (0.88)^{9-2}+^9C_3 (0.12)^3 (0.88)^{9-3}$

$=36(0.12)^2 (0.88)^7+84(0.12)^3 (0.88)^6$

$=0.279266611163$

$\approx 0.28$

$=28\%$

Point W is located at (0, 7), and point X is located at (4, 0). Julianne wants to find point F on WX such that the ration of WF

aniked [119]

The coordinate of point F will be (1.6,4.2) for the given line segment.

<h3> What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given the F intercept 2 and 3

x = [2(4) + 3(0)]/(2+3)

x = 8/5 = 1.6

Similarly

y = [2(0) + 3 (7)]/(2+3)

y = 21/5 = 4.2

Hence "The coordinate of point F will be (1.6,4.2) for the given line segment".
