Answer:
C. $0.19/ounce
Step-by-step explanation:
We know that 16 ounces = 1 pound but we have 5 pounds,
So, we do 5 times 16.
We get 80 (ounces) and we divided ounces by total cost ($15.25)
We get our answer:
$0.19/ounce
Let X be a discrete random variable with geometric distribution.
Let x be the number of tests and p the probability of success in each trial, then the probability distribution is:
P (X = x) = p * (1-p) ^ (x-1). With x = (1, 2, 3 ... n).
This function measures the probability P of obtaining the first success at the x attempt.
We need to know the probability of obtaining the first success at the third trial.
Where a success is defined as a customer buying online.
The probability of success in each trial is p = 0.3.
So:
P (X = 3) = 0.3 * (1-0.3) ^ (3-1)
P (X = 3) = 0.147
The probability of obtaining the first success at the third trial is 14.7%
Answer:
Step-by-step explanation:
At the lying lemon used car company each salesperson makes $5.75 per hour and receives 6 1/2% commission on sales. Converting
6 1/2% to decimal, it becomes 6.5%
If a Salesperson worked for 8 hours, the amount that he would earn would be
8 × 5.75 = $46
If the salesperson sold a car for $9290, his commission would be
6.5/100 × 9290 = 0.065 × 9290 = $603.85
Total amount that the sales person would earn is
46+ 603.85 = $649.85
