Answer:
l=15 m
Step-by-step explanation:
Given that a blueprint of a plot of land has a scale of cm to m.
i.e. if it measures 1 cm in blue print actual dimension is 1 m.
The length of land measures 15 cm on the blueprint.
For 1 cm actual length = 1 m
So for 15 cm actual length = 15 m
So we get
if l represents the length of the actual piece of land,
l=15 m

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
