Answer:
0.85
Step-by-step explanation:
Given two events A and B, the probability that either A or B occurs is given by:

where
the probability that A occurs
is the probability that B occurs
is the probability that both A and B occur at the same time
In this problem, we know the following facts:
is the probability that the car requires an oil change
is the probability that the car requires a brake repair
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:

Find the length of the field first. To do this, write a formula for the perimeter, P, of the field: P = 210 ft = 2(45 ft) + 2L.
Then 2L = 210 - 90 = 120, and L = 60 (feet).
The area of the field is thus WL = (45 ft)(60 ft) = 2700 sq ft
Answer:
D.
Step-by-step explanation:
the graph has a y intercept of -3
try substituting any point in one of the equations that fit the graph in this one that is D.
try(1,1)
1<1-3
1<-3
it is false so shade the outside of the graph
hope it helps
Answer:
C. 576 ft.
Step-by-step explanation:
If the garden has a perimeter of 72feet and the lengths of each of the sides are lengthened by a factor of 8.
Perimeter of the enlarged garden = perimeter before enlargement x enlargement factor
That’s 72 x 8
576feet
We will take the common terms in the expressions-
Here in the expression, 3y is a common term.
So,


So, the answer is
