Answer:
Option C) supplementary
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If two angles are supplementary, then their sum is equal to 180 degrees
In this problem
The measure of angles are
60° and 120°
Their sum is equal to
60° + 120°=180°
therefore
The two angles are supplementary

Answer:
Approximate probability that is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean = 2.2
Standard deviation = 1.4
Sample size ( n ) = 52
Let be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that is less than 2 =
= Putting
= ( Using Z table )
= 0.1515
The answer is a positive 0.33
