Step-by-step explanation:
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:
Using substitution:
4x+2y=12
y=8x+1
4x+2(8x+1)=12
distribute
4x+16x+2=12
combine like terms
18x+2=12
subtract 2 from both sides
20x=10
divide each side by 20
x=10/20
reduce
x=1/2
plug in x for the y= equation
y=8(1/2)+1
multiply
y=4+1
add
y=5
answer:
(1/2,5)
Answer:
My best answer is option number 4.
Step-by-step explanation:
Because the first 3 answers follow a specific pattern in addition and division, i.e. they only go up to 4 different numbers, whereas with the 4th option, that changes. Not only that, but if you look closely, the 4th option adds 6 to itself 5 times, that's the same as 6x5, which equals 30, so if you divide 30 by 5, its almost pointless seeing as how you already know it's gonna get you 6.
Answer:
2t
Step-by-step explanation:
The expressions are not the same because different terms are negative. We can visualize the difference by rewriting the expressions as 13t + (-2t) and (-13t) + 2t. In the first expression, 13t-2t, the 2t is negative because it is being subtracted, and subtracting a number is the same as adding a negative.
