Find the constant of variation, k, for the above table. What does this represent?

Answers

Answer 1

Answer: we see that wne price increase, tax increse
direct variation
y=kx
price=x
tax=y

when x=1
y=0.06
0.06=k1
0.06=k

k is 0.06
it reprsent the rate of change

A container contains balls numbered from 1 through 55. A ball is drawn randomly and replaced. Then a second ball is drawn randomly. What is the probability that the first ball is number 9 and the second ball is number 41?

Answers

Answer:

1/3025

Step-by-step explanation:

Prob. of getting a 9 is 1/55; likewise for 41. multiply the 2 probs. together. (1/55)^2=1/3025≈0.00033057851

Final answer:

The probability of drawing ball number 9 first and then drawing ball number 41 from a container of balls numbered 1 to 55, with replacement is 1/3025.

Explanation:

The question pertains to the field of probability in Mathematics. It is asking for the probability of first drawing ball number 9 and then drawing ball number 41 from a container that contains balls numbered from 1 to 55. Since the ball is replaced after the first draw, the total number of possibilities remains the same for both draws. Therefore, the individual probability of drawing either one of those balls at a certain draw is 1/55.

Given that these are independent events, we multiply the probabilities. Hence, the probability of drawing ball number 9 first and then drawing ball number 41 is: P(9 and 41) = P(9) x P(41) = (1/55) x (1/55) = 1/3025.

Find the product.

a^4(3a ^2 - 2a + 1)

Answers

   a⁴(3a² - 2a + 1)

We just have to multiply each term inside the parentheses by a⁴ .

   a⁴(3a² ) = 3a⁶

   a⁴( - 2a ) = -2a⁵

   a⁴( 1) = a⁴

Now, just addum up : 3a⁶ - 2a⁵ + a⁴

Answer:

3A^6-2a^5+a^4
