Let x be the discrete random variable whose value is the number of successes in n trials.
The probability distribution function for x of the binomial distribution B(n,p) is defined as
Given that the random sample size is
let x represent number of customers who purchase running shoes
Let "p" be the probability of customers in a sporting goods store purchase a pair of running shoes.
It is given that 70% of the customers in a sporting goods store purchase a pair of running shoes.
Thus
Thus the Probability distribution of x is given by
, where
Answer:
1. By substitution property of inequality
5(9.5)+4.565
2. By using multiplication in equality then we get
47.5+4.5x65
3. The five friends will have 3 snacks to split.
Step-by-step explanation:
Given
Five friends have total money= $65
Cost of each movie ticket= $9.50
Cost of each snack item= $4.50
Let ,five friends have total snacks = x
Total movie tickets=5
Because total number of friends=5
The inequality expressionis given by
I Step:
Reason: By using substitution property of inequality
65-47.5[/tex]
( by subtarction 47.5 from both sides)
( by dividing 4.5 on both sides )
Because they can buy maximum 3 snacks .
Beacause the number of snacks is natural number so we can't take in rational numbers.
<h3>Hence, the five friends will have 3 snacks to split.</h3>
