Answer:
m∠4=160°
m∠6=20°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠6+m∠4=180° ----> equation A (by consecutive interior angles)
m∠6=(1/8)m∠4 ---> equation B
substitute equation B in equation A
(1/8)m∠4+m∠4=180°
Solve for m∠4
(9/8)m∠4=180°
m∠4=180°(8)/9
m∠4=160°
<em>Find the measure of m∠6</em>
m∠6=(1/8)m∠4
m∠6=(1/8)(160°)=20°
Answer:
a) There are no evidence that Calvin is correct.
b) There are evidence that Calvin is correct.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1 ounce
Sample size, n = 23
First, we design the null and the alternate hypothesis
P-value = 0.086
a) Significance level = 5% = 0.05
Since
P-value > Significance level
We fail to reject the null hypothesis and accept it. Thus, the chips bag contain one ounce of product. Thus, there are no evidence that Calvin is correct.
b) Significance level = 10% = 0.10
Since
P-value < Significance level
We reject the null hypothesis and accept the alternate hypothesis. Thus, the chips bag contain less than one ounce of product. Thus, there are evidence that Calvin is correct.
