Answer:
Direct Variation. Since k is constant we can find k when given any point by dividing the y-coordinate by the x-coordinate.
= (7a + 2b)(7a + 2b)
= (7a +2b)^2
I think 3x-4y-6=0

Answer: 0.0899.
Step-by-step explanation:
Given: CNNBC recently reported that the mean annual cost of auto insurance is 1048 dollars, the standard deviation is 282 dollars.
Sample size : n= 55
Let
be the sample mean.
The probability that a sample of size n =55 is randomly selected with a mean less than 997 dollars:


Hence, the required probability = 0.0899 .
