Candace surveyed every 10th student that walked onto campus. She asked them if they were planning to read any books over the summer. She ended up surveying 50 people. 15 of them said yes. If there are 1000 students at her school, predict about how many will be reading over the summer. ​

not whoever wrote this question. every 10th person is surveyed. she surveyed 50 people. that mean 500 people and 50 surveyed people. then at the end the teacher said there is 1000 students. your teacher wrote you a bad question with no right answers.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
