Answer:
c
Step-by-step explanation:
t(a+2)= 3+a+2/a+2-3= 5+a/a-1
Answer:
Associative property
Step-by-step explanation:
(a)
12+0.72(8)
12+5.76
17.76 qts of antifreeze
(b)
100(12+8(.72))/(12+8)
100(12+5.76)/20
100(17.76)/20
5(17.76)
88.8%
A = P(1+rt)
A (Future) = 450(2) = 900
P (Principal) = 450
R (Rate) = 14% = .14
T (Time) = Unknown
Create the equation:
900=450(1+.14t)
Distribute the 450:
900=450 + 450(.14t)
Multiply the 450(.14t)
900=450 + 63t
Subtract the 450:
450 = 63t
Divide by 63:
t=7.142857
Answer:
It will take 7.1 years.
Answer:
77%
Step-by-step explanation:
Given the following :
Probability of winning both games = 50%
Probability of winning just the first game = 65%
Let the probability of winning the ;
First game = p(A) = 65%
Second game = p(B)
Both games = p(A and B) = 50%
What is the probability that the team will win the 2nd game given that they have already won the first game
The above question is a conditional probability question :
Probability of winning the second Given that they've already won the first = p(B | A)
p(B | A) = (A and B) / p(A)
p(B | A) = 50% / 65%
p(B | A) = 0.5 / 0.65
p(B | A) = 0.7692307
= 76.9% = 77%
