Answer:
Step-by-step explanation:
The first step is to distribute the 2m and 3 to (
), like so:


Then, add like terms:

Answer:
answer A. 0.5
Step-by-step explanation:
hello
as A and B are independent P(B/A)=P(B) =0.5
in short, the information provided by the event A does not impact at all the event B. so knowing A or not does not impact the probability of B.
you can use the formula as well P(B/A)=P(A and B) / P(A)=(P(A)xP(B))/P(A)=P(B)
hope this helps
To find the answer you add 7 and 8 which is 15.
Then you divide 60 and 15 which is 4.
Now you multiply 7 and 4 which is 28 and multiply 8 and 4 which is 32.
You have an equivelant ratio of 28:32 now.
The longer piece is 32-m.
Answer: Choice C. an = 8 + 9(n-1)
===========================================
Work Shown:
a1 = 8 is the first term
a7 = 62 is the seventh term
an = a1+d(n-1) = nth term of arithmetic sequence
a7 = a1+d(7-1) ... plug in n = 7; solve for d
62 = 8+d(6)
62 = 6d+8
6d+8 = 62
6d = 62-8
6d = 54
d = 54/6
d = 9 is the common difference
an = a1 + d(n-1)
an = 8 + 9(n-1) is the nth term of this arithmetic sequence
