Please help. The topic is angles. Anything you know helps
Lorico [155]

Answer:

all of them except straight and reflex

Step-by-step explanation:

when angles are supplementary it means that they add up to 180

an acute angle is supplementary to an obtuse angle

an obtuse angle is supplementary to an acute angle

a right angle is supplementary to a right angle

but a reflex angle is over 180 so it's not supplementary to anything

and a straight angle is already 180 so it has no supplements either

The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.8
Ber [7]

Answer:

0.85

Step-by-step explanation:

Given two events A and B, the probability that either A or B occurs is given by:

p(A\cup B) = p(A)+p(B)-p(A\cap B)

where

p(A) the probability that A occurs

p(B) is the probability that B occurs

p(A\cap B) is the probability that both A and B occur at the  same time

In this problem, we know the following facts:

p(o) = 0.83 is the probability that the car requires an oil change

p(b)=0.17 is the probability that the car requires a brake repair

p(o\cap b) = 0.15 is the probability that the car requires both an oil change and brake repair

Therefore, the probability that either o (car requiring oil change) or b (car requiring brake repait) occur is:

p(o\cup b)=p(o)+p(b)-p(o\cap b)=0.83+0.17-0.15 = 0.85
