(f · g)(x) = f(x) · g(x)
f(x) = 3x + 2; g(x) = x^2 + 1
(f · g)(x) = (3x + 2)(x^2 + 1) = 3x^3 + 3x + 2x^2 + 2 = 3x^3 + 2x^2 + 3x + 2
In standard form it would be x + 2y = 8.
x + 2y = 8
2y = -x + 8
y = -1/2x +4
Answer:
Step-by-step explanation:
-9x + 1 = -x + 17
-8x + 1 = -17
-8x = -16
x = 2
Considering the situation described, the confidence interval is given by:
(0.35, 0.51).
<h3>What is a confidence interval?</h3>
It is given by the <u>estimate plus/minus the margin of error</u>.
For this problem, we have that:
- The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.
Then, the bounds of the interval are given by:

Answer:
<em>The coordinate of the midpoint is 1/2</em>
Step-by-step explanation:
<u>Midpoint</u>
The midpoint of a segment defined in a one-dimension system is
Where x1 and x2 are the coordinates of the points.
The given segment has endpoints x1=-7 and x2=8, thus:
The coordinate of the midpoint is 1/2
