Answer:
Mean of the binomial distribution μ = 2.38
Standard deviation of the binomial distribution σ = 1.2533
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given Population proportion
p = 34 % = 0.34
q = 1- p
= 1 -0.34
= 0.66
q = 0.66
Mean of the binomial distribution
μ = n p = 2.38
Standard deviation of the binomial distribution
σ = √n p q = 1.2533
Answer:
see below
Step-by-step explanation:
Let r = number of rides
total amount of money spent has to be less than or equal to 50
costs are admission and food and rides
rides cost 1.50 each
50≥ admission + food + rides
50 ≥ 15 +10 + 1.50r
Combine like terms
50 ≥25 + 1.50 r
Subtract 25 from each side
50-25 ≥25-25 + 1.50 r
25 ≥ 1.50 r
Divide by 1.5 on each side
25/1.5 ≥ 1.5r/1.5
50/3 ≥ r
Changing this to a mixed number
16 2/3 ≥r
We can only take a whole number of rides
r = 16
Beverly has not spent all of her 50 dollars since there was a fraction for the rides
cost = 15 +10 + 1.50r
15+10 + 1.5*16
25+24
49
She has 1 dollar left
