Reactivate

C) Girls varied more in how they liked peanut butter than the boys did.

D) There is not enough information to know if any of the above are true

Option C) Girls varied more in how they liked peanut butter than the boys did.

Step-by-step explanation:

From the options the most appropriate will be option C which says: Girls varied more in how they liked peanut butter than the boys did..

This is because in the experiment, henri found out that the girls had a mean of 7 with a range of 9 and the boys had a mean of 8 with a range of 5.

The range of the girls responses are far higher than that of the boys.

So it means their ratings were more varied and not within similar ratings scale.

after simplifying it i got: -36.25 as my answer. hope that !

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
