Answer:
B) 15.85%
Step-by-step explanation:
normalcdf(minimum,maximum,μ,σ)
normalcdf(39,189,264,75)
≈0.1573
≈15.73%
Therefore, the closest answer is B
Answer:
7/10
Step-by-step explanation:
1/5=6
10%=3
30-6-3
21
21/30=7/10
Step-by-step explanation:
step 1. I guess we assumed the two lines across the transversal are parallel
step 2. 3x + 1 = 85 (definition of alternate exterior angles)
step 3. 3x = 84 (subtract 1 from each side)
step 4. x = 28. (divide both sides by 3)
Answer:
Hence the value for the mean is 80 and the standard deviation for the original sample is 8.
Step-by-step explanation:
Mean = 83-3 = 80.
Here the standard deviation didn't change = 8.
