Answer:
the length of the other altitude of the given parallelogram will be 6 units and option B is the correct choice.
Answer:
Option B) 0.1032; fail to reject
Step-by-step explanation:
We are given the following information in the question:
We used two tailed z-test to perform the hypothesis.
Level of significance, α = 0.05
We have to calculate the p-value.
We calculate the p-value from the normal standard z-table.
p-value = 0.1032
Since,
p-value > Level of significance
We fail to reject the null hypothesis and accept it.
Option B) 0.1032; fail to reject null hypothesis
Answer:
865
Step-by-step explanation:
We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.
Now we have the following formula:
n = [z / E] ^ 2 * (p * q)
where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.
Replacing these values we are left with:
n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]
n = 864.36
865 by rounding to the largest number.
Answer:
144 cubic inches
Step-by-step explanation:
a=lxwxh a=6*6*4
actual cost is 950+23,500=24450
he sold them for 25000 so his profit is 25000-950-23500=550
