Answer:
x^3 + x^2 + 4x - 20.
Step-by-step explanation:
I have assumed there is a + between the 3x and the 10.
f(x) * g(x)
= (x^2 + 3x + 10)(x - 2)
= x^3 + 3x^2 + 10x - 2x^2 - 6x - 20
= x^3 + x^2 + 4x - 20.
Answer:
i think so!
Step-by-step explanation:
Bob's age is 22
And her sisters age is 14
If you'll add 22&14 the answer would be 36
And if you'll subtract 22&14 the answer would be 6
Answer: The proportion that will qualify is 0.0314 or 3.14%.
First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.
(128 - 141) / 7 = -1.86
Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.
