For a binomial probability distribution, it is unusual for the number of successes to be less than μ − 2.5σ or greater than μ +
kirill [66]

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)

3x(5x+2)(x-4)=0 what do the X's equal to
Lorico [155]

After solving the equation 3x(5x+2)(x-4)=0 we get values of x: x=-3, x=-2/5\,\,and\,\,x=4

Step-by-step explanation:

We need to find the value of x from the equation: 3x(5x+2)(x-4)=0

Solving the expression:

3x(5x+2)(x-4)=0

Using the Zero Factor Principle: if ab=0 then a=0 and b=0

So, 3x=0, 5x+2=0\,\,and\,\, x-4=0

x=-3, x=-2/5\,\,and\,\,x=4

So, After solving the equation 3x(5x+2)(x-4)=0 we get values of x: x=-3, x=-2/5\,\,and\,\,x=4
