Answer:
x=10
Step-by-step explanation:
1/5(x)-2/3=4/3
Add 2/3 to each side
1/5(x)-2/3+ 2/3=4/3+2/3
1/5x = 6/3
1/5 x = 2
Multiply each side by 5
1/5x *5 = 2*5
x = 10
Answer:
Mean of the binomial distribution μ= 6
Variance of the binomial distribution λ² = 4.2
Step-by-step explanation:
<u>Explanation:-</u>
The probability a Gallup poll showed that 30% of Americans are satisfied with the way things are going in the United States.
p = 30% = 0.3
q =1-p = 1- 0.3 =0.7
a sample of 20 Americans is selected as part of a study of the state of the nation
size of the sample 'n' =20
we will use binomial distribution
<u>mean</u>:-
Mean of Americans who are satisfied with the way things are going in the United States (μ) = np
μ= 20 X 0.3
μ= 6
<u>Variance</u>:-
Variance of Americans who are satisfied with the way things are going in the United States λ² = n p q = 20 X(0.3)(0.7)
λ² = 4.2
Answer:
70%?
Step-by-step explanation:
I think this because half of 40 is 20 so that's 50 percent then 4 is 10 percent times that by 2 its 70 percent I think bit dont trust me I'm just doing this in my head..
