Tom has a bag of marbles: 3 red and 4 blue. He reaches in the bag and records
the result. He DOES NOT replace the
marble. He reaches in again and pulls out
another red marble. What is the
COMPOUND probability that Tom will pull
out a blue and a blue? (Show your work

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

i think it would be c
