A survey was given to people who own a certain type of car. What percent of the people surveyed were completely satisfied with the​ car?

Answers

Answer:

65%

Step-by-step explanation:

To find the specific percentage of people who were completely satisfied, you first need to find the total number of people who took the survey. This number turns out to be (by adding the number of people per each category together) 2,500 people.

Then, to find the percentage that were completely satisfied, divide 1,625 (people completely satisfied) by 2,500 (total people), to get 0.65.

This converted to a percentage is 65%.

Which equation applies the associative property of multiplication?

A: 4/9 x (-3/8) x 9/4 = 4/9 x 9/4 x (-3.8)

B:​ −12/5 x (7/12 x 1/9) x 8/5 = (−12/5 x 7/12) x (1/9 x 8/5)

C: ​(−4/11 − 2/3) − 3/4 = −4/11 − (2/3 − 3/4)

D:​ 1/2 x (5/8 + 3/6) = (1/2 x 5/8) + (1/2 x 3/6)

Answers

Answer: B

Explanation:

The associative property of multiplication is a rule that states the result of three numbers being multiplied is the same regardless of the order of the numbers. In choice c, -12/5, 7/12, and 1/9 are being multiplied by each other on both sides of the equation, but they are in different orders, hence Choice C applies the associative property of multiplication.
