A bakery recorded the number of muffins and bagels it sold for a seven day period. For the data presented, what does the value of 51 summarize?

A) mean of bagels

B) mean of muffins

C) range of bagels

D)range of muffins

The value 51 summarizes A) the mean of the bagels.

Step-by-step explanation:

Step 1:

There are 7 sample values for muffins and bagels.

To take the mean of a given set of numbers we add all the terms and then divide the sum by the number of terms that were added.

The range of a function represents all the possible numbers in that set. The range cannot be represented by a single number so the answer cannot be option C or option D.

Step 2:

The mean of the muffins =

The mean of the bagels =

So by calculating the means of the two sets of values, we have the number 51 represents the mean of bagels which is option A.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is c.
