387,562
The 8 is in the ten thousands place, so it equals 80,000.

7,328,562
The 7 is in the millions place, to it equals 7,000,000.

The sum is the value of two numbers added together (the answer to an addition problem).

80,000 + 7,000,000 = 7,080,000

yaroslaw [1]

Answer:

3.93% probability that both say service is poor

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The customers are chosen without replacement, and the order in which they are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

What is the probability that both say service is poor?

Desired outcomes:

Two saying it is poor, from a set of 66. So

D = C_{66,2} = \frac{66!}{2!(66-2)!} = 2145

Total outcomes:

Two customers from a set of 331. So

T = C_{331,2} = \frac{331!}{2!(331-2)!} = 54615

Probability:

p = \frac{D}{T} = \frac{2145}{54615} = 0.0393

3.93% probability that both say service is poor

Find three consecutive even numbers whose sum is 1674.
Norma-Jean [14]

Answer:

556, 558, and 560

Step-by-step explanation:

1674/3 = 558 (An even number, yay)

So 558 + 558 + 558 = 1674

Subtract two from the first one and add two to the last (still equal)

556 + 558 + 560

adding them equals 1674 so the answer is

556, 558, and 560
