SAME SCENARIO - DIFFERENT QUESTION

Eliza intends to buy a new vehicle. She wishes to estimate the average fuel efficiency (in miles per gallon) of all family sized SUVs currently available on the market. Eliza selects a random sample of 15 family sized SUVs on the market and looks up their fuel efficiency on a trusted website. The results of the random sample are shown below:

27, 28, 30, 28, 28, 31, 29, 33, 28, 28, 31, 33, 41, 41, 25

If Eliza were to take another random sample of 15 SUVs from the same population, would she be likely to get the exact same value for the mean?

Question 2 options:

Yes, it is likely that Eliza will get the exact same value for the sample mean


No, it is not likely that Eliza will get the exact same value for the sample mean

The difference of x and y is 14. The value of x is 3 more than twice the value of y. Write two equations and graph to find the value of x.

Store A sells boxes of rice for $2.50 each.

Store B sells rice by the pound for $2.50 per pound.

The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.

The domain of c(n) = 2.5n is all the real numbers.

For each store, drag the restriction needed on values of n for c(n) to model each situation.

Solve the equation:
3x + 1 over 4y2
