Dennis has less than 70 min. to spend on some homework questions. he spent 10 min. on the first two questions. the rest of the questions will take 5/2 min. each. what statement describes the solution to this inequality? a. dennis can complete fewer than 4 questions.
b. dennis can complete fewer than 24 questions.
c. dennis can complete fewer than 32 questions.
d. dennis can complete fewer than 60 questions.

b is correct

Step-by-step explanation:

i took the test on k12

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;

5
