Answer:

y = 1

Step-by-step explanation:

Given:

a^{3y - 5} = \frac{1}{a^2}

Apply the negative exponent rule

a^{3y - 5} = a^{-2}

The bases will cancel each other

3y - 5 = -2

3y - 5 + 5 = -2 + 5

3y = 3

\frac{3y}{3} = \frac{3}{3}

y = 1

Please help<br><br> -3/4(8n + 12) = 3(n-3)
Dennis_Churaev [7]

Step-by-step explanation:

-  \frac{3}{4} (8n + 12) = 3(n - 3)

- 3(8n + 12) = 12(n - 3)

\cancel{- 3}(8n + 12) =  \cancel{12}(n - 3)

- (8n + 12) = 4(n - 3)

- 8n - 12 = 4n - 12

- 8n - 4n =  - 12 + 12

- 12n = 0

n = 0

The number of responses to a survey are shown in the Pareto chart. The survey asked 1052 adults how they would grade the quality
Goryan [66]

Answer: (a) P(no A) = 0.935

              (b) P(A and B and C) = 0.0005

              (c) P(D or F) = 0.379

              (d) P(A or B) = 0.31

Step-by-step explanation: <u>Pareto</u> <u>Chart</u> demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.

The Pareto chart below shows the number of people and which category they qualified each public school.

(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:

P(no A) = 1-\frac{68}{1052}

P(no A) = 1 - 0.065

P(no A) = 0.935

b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:

P(A and B and C) = (\frac{68}{1052})(\frac{258}{1052})(\frac{327}{1052})

P(A and B and C) = \frac{5736888}{1164252608}

P(A and B and C) = 0.0005

c) Probability of an D or an F is the sum of probabilities of an D and of an F:

P(D or F) = \frac{269}{1052} +\frac{130}{1052}

P(D or F) = \frac{399}{1052}

P(D or F) = 0.379

d) Probability of an A or B is also the sum of probabilities of an A and of an B:

P(A or B) = \frac{68}{1052} +\frac{258}{1052}

P(A or B) = \frac{326}{1052}

P(A or B) = 0.31
