Aspinner is spun twice. it has a 3,5,7, and 9 on it. how many outcomes could produce a product greater than 21?

answer choices:
12
10
11
13

11

Step-by-step explanation:

What numbers on both spins would create a PRODUCT GREATER THAN 21?

3 and 9

5 and 5

5 and 7

5 and 9

7 and 7

7 and 5

7 and 9

9 and 9

9 and 3

9 and 5

9 and 7

So, as we can see, we have 11 possibilities of getting a product GREATER than 21 (not 21...).

Correct answer is 11.

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;
