The department of labor would like to test the hypothesis that the average hourly wage for recent college graduates is less than $20. a random sample of 24 recent college graduates averaged $19.30 per hour with a standard deviation of $3.20 per hour. the department of labor would like to set ? = 0.10. use the critical value approach to test this hypothesis.

associative property of multiplication

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
