Answer:

Breaking up the multiplicand 8 into (5+3) allows us to apply the associative property of multiplication.  See below.

Step-by-step explanation:

5*7 = 35.  We want the product 8*7.  Note that 8 = 5+3.  Thus, 8*7=(5+3)(7) = 35 + 21, or 56.

insens350 [35]

Answer:

<em>OPtion B. Both the mean and median will increase, but the mean will increase by more than the median.</em>

<em />

Explanation:

You should not need to do calculations to determine <em>how buying the horse affects the mean and median.</em>

Without the horse, there are 8 animals. When the data are ordered, the <em>median</em> is the average of the 4th and the 5th weights: (7 + 27)/2.

With the horse, there are 9 animals. The median will be the 5th weight: 27

Then, the median increases from (7 +27)/2 to 27.

What about the <em>mean</em>?

The horse's weight is well beyond the weight of the other 8 animals. The range increases from 160 - 2 = 158 to 900 - 2 = 898.

Then, when you calculate the mean inlcuding the weigth of the horse, there will be a high increase.

Thus, without further calculations, you can conclude that "<em>B. Both the mean and median will increase, but the mean will increase by more than the median"</em>

Answer:

Step-by-step explanation:

Given that there are 8 candidates for student government: Hal, Mary, Ann, Frank, Beth, John, Emily, and Tom.

The three candidates that receive the highest number of votes become candidates for a runoff election.

i.e. 3 persons out of 8 to be selected for becoming candidates for a runoff election.
