Answer:

<h2>The answer is A</h2><h2>A. S = 1/2p - L</h2>

Step-by-step explanation:

Step one:

given the perimeter function

P = 2S + 2L

we are expected in this problem to change the subject of the formula to S

Step two:

firstly, let us isolate the term that has S

2S=P-2L

divide both sides by 2

2S/2= (P-2L)/2

S=P/2-L

S = 1/2p - L

A health statistics agency in a certain country tracks the number of adults who have health insurance. Suppose according to the

Fynjy0 [20]

Answer:

a) 15.4% probability that a randomly selected person in this country is 65 or older

b) 0.023 = 2.3% probability that the person is 65 or older

Step-by-step explanation:

To solve b), i will use the Bayes Theorem.

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

(a) What is the probability that a randomly selected person in this country is 65 or older?

22.7% of people in the county are under age 18

61.9% are ages 18–64

p% are 65 or older.

The sum of those is 100%. So

22.7 + 61.9 + p = 100

p = 100 - (22.7+61.9)

p = 15.4

15.4% probability that a randomly selected person in this country is 65 or older.

(b) Given that a person in this country is uninsured, what is the probability that the person is 65 or older?

Event A: Uninsured

Event B: 65 or older.

15.4% probability that a randomly selected person in this country is 65 or older.

This means that $P(B) = 0.154$

1.4% of those 65 and older do not have health insurance.

This means that $P(A|B) = 0.014$

Probability of not having insurance.

22.7% are under 18. Of those, 5.4% do not have insurance.

61.9% are aged 18-64. Of those, 12.8% do not have insurance.

15.4% are 65 or over. Of those, 1.4% do not have health insurance. So

$P(A) = 0.227*0.054 + 0.619*0.128 + 0.154*0.014 = 0.093646$

Then

$P(B|A) = \frac{0.154*0.014}{0.093646} = 0.023$

0.023 = 2.3% probability that the person is 65 or older

10) Find the distance between (2, 3) and (-3, -2) A) 2 B) 5 C) 50 = 5 2 D) 25

PSYCHO15rus [73]

Answer:

The answer is

<h2> $5 \sqrt{2} \: \: \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2, 3) and (-3, -2)

The distance between them is

$d = \sqrt{( {2 + 3})^{2} + ({3 + 2})^{2} } \\ = \sqrt{ {5}^{2} + {5}^{2} } \\ = \sqrt{25 + 25} \\ = \sqrt{50} \\ = 5 \sqrt{2}$

We have the final answer as

$5 \sqrt{2} \: \: \: \: units$

Hope this helps you
