Answer:
B. 80
Step-by-step explanation:
3 consecutive integers: x-1 , x , x+1
(x-1) + x + (x+1) = -27
3x = -27
x = -9
smallest: -9-1 : -10
largest: -9+1 : -8
product of the smallest and largest of the three integers: (-10)*(-8)=80
Answer:
Mean = 2
Standard deviation = 1.356
Step-by-step explanation:
We are given;
Probability of taxpayers that make mistakes when filling out forms: p = 0.08
Sample size; n = 25
In binomial distribution;
Means is;
μ = np
Thus;
μ = 25 × 0.08
μ = 2
Formula for standard deviation here is;
σ = √(np(1 - p))
σ = √(25 × 0.08(1 - 0.08))
σ = 1.356
There are 6 possible outcomes on a dice. Meaning when you roll it it could be any of them. Because 3 is one of the 6 the answer would be 1/6
