Answer:
90°
Step-by-step explanation:
X=180°-(45°+45°){being square property}
X=180°-90°
X=90°
Answer:
Step-by-step explanation:
Let X denote the random variable that obeys the normal distribution.
Given that:
<u>For morning flights</u>
Mean = 15
standard deviation = 5
Sample size = 10
The Z - score is calculated as:
Z = 3
<u>For evening flights</u>
Mean = 20
standard deviation = 3
Sample size = 10
Z = 3.33
Hence, from the above z-scores, we will realize that the evening flight is more late than usual.
Add 5 to both sides then divide both sides by -10.
