Answer:
A.
m = -1
Step-by-step explanation:
Slope Formula: 
Simply plug in your 2 coordinates into the formula to find slope <em>m</em>:
m = (6 - 4)/(2 - 4)
m = 2/-2
m = -1
Answer:
(u + 1)(u - 1)(u² + 8)
Step-by-step explanation:
<u>Here is the steps:</u>
- u⁴ + 7u² - 8 =
- u⁴- u² + 8u²-8 =
- u²(u² - 1) + 8(u² -1) =
- (u² - 1) (u² +8) =
- (u + 1)(u - 1)(u² + 8)
Step-by-step explanation:
First, find the expected value.
μ = 0 (0.28) + 1 (0.37) + 2 (0.22) + 3 (0.08) + 4 (0.05)
μ = 1.25
Now find the standard deviation.
σ² = (0−1.25)² (0.28) + (1−1.25)² (0.37) + (2−1.25)² (0.22) + (3−1.25)² (0.08) + (4−1.25)² (0.05)
σ² = 1.2075
σ = 1.099
If we were to select many boxes of bulbs randomly, the number of defective bulbs would typically vary about 1.099 from the mean.
