<h3>Part A:</h3>
- 1 and 4: Corresponding angles
- 1 and 3: Vertical angles
- 1 and 2/2 and 3/2 and 4: Supplementary angles
- 3 and 4: Alternate interior angles
<h3>Part B:</h3>
With the knowledge that m∠1 = 81°, let's use these relationships to find the rest of the angles:
- 1 and 3 are vertical: their angle measures are the same, so m∠3 = 81°
- 1 and 4 are corresponding: their angle measures are <em>also </em>the same, so m∠4 = 81°
- Finally, 1 and 2 are supplemental: their angle measures add up to 180°, so 81 + m∠2 = 180, making m∠2 = 99°
Answer:
Reject H0 if x > cv
Step-by-step explanation:
The hypothesis :
H0 : μ ≤ 425
H1 : μ > 425
Standard deviation, s = √2500 = 50
Sample size, n = 100
xbar = 433.5
The test statistic, Z :
(xbar - μ) / s/√n
(433.5 - 425) / 50/10
Z = 8.5 / 5 = 1.7
The decision region ;
|Z| > Z0.01 ; Reject H0
From Z table ;critical value, Z0.01 = 2.33
1.7 < 2.33 ; We fail to reject then Null and conclude that thee is no significant evidence support the claim that population mean income has increased.
