39 percent of all customers who enter a store will make a purchase. suppose that 6 customers enter the store and that these customers make independent purchase decisions. (1) use the binomial formula to calculate the probability that exactly five customers make a purchase.

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

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
