Answer:
f(g(x)) = x^4 + 12x^3 + 14x^2 -132x + 123
Step-by-step explanation:
Here, we simply will place g(x) into f(x)
So every x in f(x) is replaced by g(x)
Thus, we have;
(x^2 + 6x + 11)^2 + 2
= (x^2+6x-11)(x^2 + 6x -11) + 2
= x^4 + 6x^3 -11x^2 + 6x^3 + 36x^2 - 66x -11x^2 -66x + 121 + 2
= x^4 + 12x^3 + 14x^2 -132x + 123
0.4% can be written as 0.004 in decimal.
Step-by-step explanation:
Let the total amount she wants to save be 'a'
Starting amount = 0.4% of the total amount
= 0.4% of a
= (0.4/100) a
0.4% = 0.4/100
= 0.004
0.4% can be written as 0.004 in decimal.
Answer:
6.68% of the female college-bound high school seniors had scores above 575.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 500
Standard Deviation, σ = 50
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:
P(scores above 575)
P(x > 575)
Calculation the value from standard normal z table, we have,
6.68% of the female college-bound high school seniors had scores above 575.
Isolate the w
w/3 = 5
Note the equal sign. What you do to one side, you do to the other.
Multiply 3 to both sides
w/3(3) = 5(3)
w = 5(3)
Multiply
w = 15
15 is your answer for w
hope this helps
