Answer:
13(3d - e + 15g).
Step-by-step explanation:
Distributive property example,
a(x + y + z) = ax + ay + az
By this property we have to convert the given expression into a distributive property form.
39d - 13e + 195g
Take the common factor out from each term of the expression,
39d - 13e + 195g = 13(3d - e + 15g)
Therefore, distributive property form of the given expression is 13(3d - e + 15g).
Answer:The correct option is a)
The upper limit of successes that would be deemed to be usual is 5, so more than 5 successes would be unusual.
Step-by-step explanation:
The mean of a binomial distribution
μ= np where n=10 and p= 0.2 q= 1-p, q= 1-0.2=0.8
μ= 10×0.2=2
σ=√npq
σ=√10×0.2×0.8=1.26
Is unusual for the number of success to be greater than μ + 2.5σ.
= 2+2.5(1.26)
=5 approximately.
So it is unusual for it to be greater than 0.5. The right option Is a)
