<em><u>Answer</u></em>

In order to use the distributive property I first get the amount of the water fell in ;

<u>One </u><u>year</u>

1.68mm

<u>A </u><u>half</u><u> </u><u>a </u><u>year</u>

½× 1.68mm

= 0.84mm

<u>One </u><u>and </u><u>a </u><u>half </u><u>years (</u><u>Using </u><u>the</u><u> </u><u>distributive</u><u> </u><u>property</u><u>)</u>

1.68mm + 0.84mm

<u>1</u><u>6</u><u>8</u><u>m</u><u>m</u> + <u>8</u><u>4</u><u>m</u><u>m</u>

100. 100

(168÷100) + (84÷100)

(168+84) ÷ 100

252 ÷ 100

<u>2</u><u>5</u><u>2</u>

100

= 2.52mm

Therefore the variation in the water level in the time period was 2.25mm

BabaBlast [244]

Answer:

C

Step-by-step explanation:

This is a sample proportion where p^ represents the sample proportion.

If we have p^ = 0.6, it means about 60% of the sample are in agreement with or significant to the case study.

The case study here is 'customers that play racquetball' and p^ was 0.16.

This means that 16% of the customers of the sample said they play racquetball.
