How do u find the area o a pyramid
2 answers:
First, find the area of the base. This base can be any polygon, but for the example, I am going to be using a square for the base. Multiply the length of the base times the width of the base.
Next, find the area of the lateral faces. These lateral faces are simply the triangles on the side that lead up to the point of the pyramid. You can do this by doing base times height of the triangle, then divide it by 2. You have to do this separately for shapes with different lengths for different sides of the bases, but with a square, you can multiply this number by 4, since there are 4 equal sides to a square.
l × w = base
b × h ÷ 2 = lateral face
I am not a professional, simply using prior knowledge!
Note- It would mean the world to me if you could mark me brainliest!

Answer: See explanation
Step-by-step explanation:
1. Use the five steps of hypothesis testing.
Step 1: The aim of the research is to conduct the five steps of hypothesis testing.
Step 2:
Null hypothesis: H0 u= 4
Population mean: H1 u = 4
Alternate hypothesis: u ≠ 4
Population mean: u ≠ 4
Step 3 and step 4 are attached.
Step 5: Based on the calculation, the calculated value of t is less than the t critical value, therefore, the null hypothesis will be failed to be rejected.
2. Sketch the distributions involved
This has been attached.
3. Explain the logic of what you did to a person who is familiar with hypothesis testing, but knows nothing about t tests of any kind.
The distribution is "t".
The means is tested by using T-test.
Chi-square is used to test the single variance.
