Determine whether the point (3,3) is in the solution set of the system of inequalities below.

Radda [10]

Answer:

The ordered pair is not a solution of the system D

explanation:

y < -3

y ≤ 2/3x - 4

y > -3

y ≥ 2/3x - 4

y < -3

y ≥ 2/3x - 4

y > -2

y ≤ 2/3x - 4

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)

Verify each case

Case A) we have

----> inequality A

----> inequality B

Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results

Inequality A

----> is not true

therefore

The ordered pair is not a solution of the system A

Case B) we have

----> inequality A

----> inequality B

Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results

Inequality A

----> is true

Inequality B

----> is true

therefore

The ordered pair is a solution of the system B

Case C) we have

----> inequality A

----> inequality B

Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results

Inequality A

----> is not true

therefore

The ordered pair is not a solution of the system C

Case D) we have

y > -2 ----> inequality A

----> inequality B

Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results

Inequality A

----> is not true

therefore

The ordered pair is not a solution of the system D

USA Today reports that about 25% of all prison parolees become repeat offenders. Alice is a social worker whose job is to counse

Answer:

P(x = 0) = 0.004

P(x = 0) = 0.047

P(x = 0) = 0.211

P(x = 0) = 0.422

P(x = 0) = 0.316

Step-by-step explanation:

We are given the following information:

We treat a person who does not become a repeat offender as a success.

P(Success) = P(person who does not become a repeat offender) = 0.75

Then the number of people follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to evaluate:

$P(x = 0)\\= \binom{4}{0}(0.75)^0(1-0.75)^4 = 0.004$

$P(x = 1)\\= \binom{4}{1}(0.75)^1(1-0.75)^3 = 0.047$

$P(x = 2)\\= \binom{4}{2}(0.75)^2(1-0.75)^2 = 0.211$

$P(x = 3)\\= \binom{4}{3}(0.75)^3(1-0.75)^1 = 0.422$

$P(x = 4)\\= \binom{4}{4}(0.75)^4(1-0.75)^0 = 0.316$

A farm has chickens and goats. Each chicken has 2 legs and each goat has 4 legs. The total number of chicken legs and goat legs

Inessa05 [86]

I’m going with 22 because 10x2 is 20 then 10x4 is 40 then 40+20 is 60 so the answer would be 22 because I would also have to add the other 2 to the problem. I’m so so so sorry if I did this wrong

Anna made 400 quarts of lemonade. She poured the lemonade into containers. Each container holds 4/7 of a quart. How many contain

julsineya [31]

400÷4/7=700
you want divide the totals amount of lemonade among pitchers that only hold 4/7 of the lemonade. if the container held 1 qt, you would divide the total by 1
