Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces
so
![SA=b^{2}+4[\frac{1}{2}bh]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7Dbh%5D)
where
b is the length side of the square base
h is the height of the triangular face
Remember that
Each lateral triangular face is a triangle 45°-90°-45°
so
we have
so
substitute in the formula
![SA=6^{2}+4[\frac{1}{2}(6)(3)]=72\ ft^{2}](https://tex.z-dn.net/?f=SA%3D6%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%286%29%283%29%5D%3D72%5C%20ft%5E%7B2%7D)

Step-by-step explanation:
Hello!
What you want to test is if there is a difference between the number of courses taken by students of different years, you can determine 4 populations of students:
Population 1: Freshmen
Population 2: Sophomores
Population 3: Juniors
Population 4: Seniors
To each population you measured the study variable, setting 4 different variables. To compare these variables the best way is to make one test where you compare the four populations at the same time, so the hypothesis is:
H₀: μ₁ = μ₂ = μ₃ = μ₄
H₁: At least one of the population means is different from the others.
The most appropriate test to use to compare the population mean of the 4 groups is an ANOVA.
I hope you have a SUPER day!
Answer:
Step-by-step explanation:
The factoring of 64 is ...
64 = 2·2·2·2·2·2
= (2·2)·(2·2)·(2·2) = 4·4·4 = 4³
= (2·2·2)·(2·2·2) = 8·8 = 8²
= 2·2·2·2·2·2 = 2⁶
