HELPP IF WRONG ILL REPROT A store employee conducted a survey of 590 randomly selected customers. According to the survey, 177 of the customers often use coupons.

How many people would you expect to use a coupon if all 5,000 people in the community visited the store?

Question 7 options:

5,310 people

1,250 people

3,750 people

1,500 people

Solution given

:total n[U]=590

customers using coupon n[C]=177

the percentage of all customers who often use coupons=177/590×100%=30%.

If n[U]=5000

no of customer using coupon be x

we have

30% of 5000=x

x=30/100×5000

x=1500

So1500 people would you expect to use a coupon if all 5,000 people in the community visited the store.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
