Acustomer service survey was conducted of 500 customers: 250 men and 250 women. the data on one of the questions show that 175 men and 160 women rate the customer service as excellent. what percentage of men gave an excellent rating? what percentage of women gave an excellent rating? what was the total percentage of customers giving an excellent rating?

men 70% women 64%

Step-by-step explanation:

Given that men and women were selected, either had the option of giving the customer service an excellent rating or not. As such , where there were 250 men and 175 men gave an excellent rating, this represents

= 175/250 × 100%

=70%

It means 70% of the men gave an excellent rating.

Likewise, where there were 250 women and 160 women rate the customer service as excellent. This represents

= 160/250 × 100%

=64%

It means 64% of the women gave an excellent rating.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
