Answer:the probability that exactly five customers make a purchase is 0.033
Step-by-step explanation:
The formula for binomial distribution is expressed as
P(x = r) = nCr × q^(n - r) × p^r
Where
p = probability of success
q= probability of failure
n = number of sample
From the information given,
39 percent of all customers who enter a store will make a purchase. It means that the probability of success, p = 39/100 = 0.39
The probability of failure q, would be 1 - p = 1 - 0.39 = 0.61
n = 6
The probability that exactly five customers make a purchase is expressed as
P(x = 5) = 6C5 × 0.61^(6 - 5) × 0.39^5
P(x = 5) = 6 × 0.61× 0.39^5 = 0.033
Answer:
Step-by-step explanation:
Pepita and Francisco each spend a equal amount of time on homework. he table shows the fraction of time they spend on each subject.
We know Pepita spent
on English and Science.
Hence, Pepita spent
on Math.
Francisco spent
on Math and Science, so he spent
on English.
The table is
.02 because 1÷53=.0188 and rounded to the nearest hundredth would be .02
Answer:
x ≤
Step-by-step explanation:
multipy both sides by twelve
move the variable to the left side and change the sign
collect like terms
divide both sides by -17 and flip the inequality sign
