Hey there!
- Factor pair basically 2 factors that you multiply the given numbers to each other to get a given product (answer)
“Factors of 72”
- So we have to find MULTIPLES that gives you 72
Answers ⬇️
▸ 1 • 72 = 72
(SAME thing with 72 • 1 = 72)
▸ 2 • 36 = 72
(SAME with 36 • 2 = 72)
▸ 3 • 24 = 72
(SAME with 24 • 3 = 72)
▸ 4 • 18 = 72
(SAME with 18 • 4 = 72
▸ 6 • 12 = 72
(SAME with 12 • 6 = 72)
▸ 8 • 9 = 72
(SAME with 9 • 8 = 72)
Good luck on your assignment and enjoy your day!

Answer:
13 years
Step-by-step explanation:
First we will have to see how much she owns her aunt:
800-448= 362
8% of 348 = 27.84
362 ÷ 27.84 = 13 years
I might be wrong but hopefully this helps :)
I think it’s B I’m not sure
Answer:
Z-test is a statistical test used to check weather two means are significant or not for unknown variance and large sample size.
Z = (M - μ) ÷ √(σ² / n)
where, M = Sample Mean = 66.075
μ = Population Mean = 90
σ² = Population Variance = 15
Now, Calculating the value of Z-test:
Z = (66.075 - 90) ÷ √(225 ÷ 40)
Z = -23.925 ÷ 2.37171
Z = -39.06936
The value of Z is -39.06936.
The value of p is < .00001 at 90% confidence level.
If the p-value is less than value of α, We accept the null- hypothesis otherwise reject.
The result is significant at p < .10.
Thus, we accept the null hypothesis.
