X is 3 because 3 sqaured is 3x3=9
Answer:
Do you want to know the surface area of the triangle or the perimeter of the triangle?
Step-by-step explanation:
If you are looking for the Surface area, plug your numbers in this formula: SA=(p x h)/(2) + B where SA is the surface area of the pyramid, p is the perimeter of the base, h is the slant height of the pyramid, and B is the area of the base.
Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let 
be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis : 
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Typically, you would use inches.
<h3>
Answer: a = f/p</h3>
===============================================
Explanation:
We'll solve for 'a' doing these two steps in this exact order
- Multiply both sides by 'a'
- Divide both sides by p
We do this because we're following PEMDAS in reverse to isolate the variable we want.
The steps look like this
p = f/a
pa = f
a = f/p
Note how ultimately the 'a' and p variables swap places when going from p = f/a to a = f/p
