Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.

Step-by-step explanation:
That's just the numbers biggest to smallest.
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72
Answer: a) 84 and b ) 2084
Step-by-step explanation:
Given : Sample standard deviation : s= $22.82
(Population standard deviation is unknown ) , so we use t-test.
Critical value or the 95% confidence intervals :
Formula to find the sample size :
a) E = 5
i.e. Required sample size : n= 84
b) E = 1
i.e. Required sample size : n= 2084
