Answer:

Step-by-step explanation:
step 1
Find the surface area of the smaller rectangular prism

where
B is the area of the base
P is the perimeter of the base
h is the height of the prism
![SA=2[(2.5)(1.5)]+2(2.5+1.5)(1.5)](https://tex.z-dn.net/?f=SA%3D2%5B%282.5%29%281.5%29%5D%2B2%282.5%2B1.5%29%281.5%29)

step 2
Find the surface area of the cube

where
s is the length side of the cube

step 3
Find the lateral area of the cylinder

where
D is the diameter of the base
L is the length of cylinder

step 4
Find the area of the base of cylinder

we have
----> the radius is half the diameter

step 5
Find the surface are of the composite figure
we know that
The surface area of the composite figure is equal to the surface area of the smaller rectangular prism plus the lateral area of the cylinder, plus the surface area of the cube, minus the area of the two bases of cylinder
so

There are 5 sides on a pentagon. penta=5 sides
Answer:

For the interpretation we consider a value for d small is is between 0-0.2, medium if is between 0.2-0.8 and large if is higher than 0.8.
And on this case 1.713>0.8 so we have a large effect size
This value of d=1.713 are telling to us that the two groups differ by 1.713 standard deviation and we will have a significant difference between the two means.
Step-by-step explanation:
Previous concepts
The Effect size is a "quantitative measure of the magnitude of the experimenter effect. "
The Cohen's d effect size is given by the following formula:

Solution to the problem
And for this case we can assume:
the mean for females
the mean for males
represent the deviations for both groups
And if we replace we got:

78÷18=4.3333333
so it's 4.33333 many pancakes with one cup
so then you multiply 4.33333... by 12 which equals 52
So you can make 52 pancakes with 12 cups of flour
They should be 54 students who know how to salsa
