A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Use a 0.100.10 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one minute?

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
