A sample of employees at a local community services center participated in a study on the effectiveness of intervention training. The sample was divided into two groups. One group received training on intervention techniques during a family crisis and the other group did not. The data in the histogram are satisfaction scores from families that were assisted by the trained employees. On what scale is the IV measured?

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

f

step-by-step explanation:

f

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
