Answer:
13
Step-by-step explanation:
(f∘g)(4) is another way of writing f(g(4)).
First, find g(4).
g(x) = 2x − 3
g(4) = 2(4) − 3
g(4) = 5
Now substitute into f(x).
f(x) = 4x − 7
f(g(4)) = 4g(4) − 7
f(g(4)) = 4(5) − 7
f(g(4)) = 13
Given that a cube has a surface area of 150 square centimeters, then the length of its side is: 150=6l2
Answer: Our required percentage would be 57%.
Step-by-step explanation:
Since we have given that
Probability of applicants with a Math SAT of 700 or more were admitted = 34%= P(A|E)= 0.34
Probability of applicants with a Math SAT of less than 700 were admitted = 16% = 0.16 = P(A|E')
Probability of all applicants had a Math SAT score of 700 or more = 38% = 0.38=P(E)
Probability of all applicants had a Math SAT score of less than 700 = 100-38=62% = 0.62=P(E')
So, using Bayes theorem, we get that
Probability of admitted applicants had a Math SAT of 700 or more P(E|A) is given by
Hence, our required percentage would be 57%.
F(x) = 3x + 7.....g(x) = 4x - 2
A. (f + g)(x)
3x + 7 + 4x - 2
7x + 5 <====
B. (f * g)(x)
(3x + 7)(4x - 2) =
3x(4x - 2) + 7(4x - 2) =
12x^2 - 6x + 28x - 14
12x^2 + 22x - 14 <===
C. f[g(x)]
3(4x - 2) + 7 =
12x - 6 + 7 =
12x + 1 <===
Answer: B.
