Answer: 32°
Explanation:
180 - 88 = 92° (Adjacent Angles on a straight line)
180 - 124 = 56° (Adjacent Angles on a straight line)
180 - 92 - 56 = 32° (Sum of angles in a triangle)
Answer:
Z= 0.253
Z∝/2 = ± 1.96
Step-by-step explanation:
Formulate the null and alternative hypotheses as
H0 : u1= u2 against Ha : u1≠ u2 This is a two sided test
Here ∝= 0.005
For alpha by 2 for a two tailed test Z∝/2 = ± 1.96
Standard deviation = s= 15
n= 10
The test statistic used here is
Z = x- x`/ s/√n
Z= 2058- 2046 / 15 / √10
Z= 0.253
Since the calculated value of Z= 0.253 falls in the critical region we reject the null hypothesis.
There is evidence at the 0.05 level that the doors are too short and unusable.
8x=160
Divide both sides by 8
X= 20. He has to sell 20 games
