Sharvay spends $15 to buy 17 pieces of candy. M&M’s cost $0.75 and candy bars cost $1. How many M&M’s and candy bars did Sharvay buy?

8 M&Ms and 9 Candy Bars

Step-by-step explanation:

$15 dollars could buy 15 candy bars, and there are 17 pieces of candy total.

Prioritizing the number of bars:

0.75 * 2 = 1.50

1.50 * 2 = 3

At least $3 were spend on M&Ms, meaning 4 M&Ms and 12 candy bars, which is only 16 candy pieces...

8 M&Ms and 9 candy bars is equivalent to 17 total candy pieces.

X is a cluster and Y is an outlier; Y could have been because the student turned in 1 assignment and did not study; and there is an increasing association between these two, meaning that as the number of assignments turned in increased, the score on the test increased.

Step-by-step explanation:

Part A:  A group of points in a scatter plot is called a cluster.  A point that is very different from the rest of the data is called an outlier.  Since this outlier was about assignments completed and test scores, this could have been caused by someone not studying.

Part B:  The association is increasing; this is because the points tend to increase on the y-axis as the x-values increase.  This means that as students submitted more homework assignments, their grades on tests increased.
