Answer:
There is a probability of 76% of not selling the package if there are actually three dead batteries in the package.
Step-by-step explanation:
With a 10-units package of batteries with 3 dead batteries, the sampling can be modeled as a binomial random variable with:
- n=4 (the amount of batteries picked for the sample).
- p=3/10=0.3 (the proportion of dead batteries).
- k≥1 (the amount of dead batteries in the sample needed to not sell the package).
The probability of having k dead batteries in the sample is:

Then, the probability of having one or more dead batteries in the sample (k≥1) is:

Step-by-step explanation:
Answer: $40 and 10 x cents.
Step-by-step explanation:
$75.50 and 18 cents - $35.50 and 8 cents = $40.00 and 10 cents per mile. For x miles, we multiply $40.00 and 10 cents by x miles.
Also, we could convert dollars to cents by multiply it by 100 Since $1 =100 cents.
7568 - 3558 cents = 4010 cents. For x miles, 4010X cents.
It is 9 and 8:3.It is because 8 and 3 do not have any factors that are the same especially because 3 is a prime number.A prime number is a number that has only a factor of itself and 1
