Step-by-step explanation:
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.
Well GPA is grade point avarage. So unless the entire class is getting all C's (2.00) the answer would be....
D)3.65
14x-5=65 ( vertically opposite angles)
14x=65+5
14x=70
x=5
z= 180-65= 115
