A man is considered overweight if he has a body mass index of 27.8 kg/m2 or greater. This point is used because it represents the sex-speci c 85th percentile for males 20-29 years of age in the 1976-1980 National Health and Nutrition Examination Survey. In 1994, of 700 men 20-34 years old, 160 were found to be overweight, whereas, in 1980, of 750 men 20-34 years old, 130 were found to be overweight. At the 1% signi cance level, do the data provide sucient evidence to conclude that for men 20-34 years old, a higher percentage were overweight in 1994 than 14 years earlier?

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 .

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry
