Which of the following expressions describes the solution set m ≥ -3? All real numbers that are negative three or less.
All real numbers that are negative three or greater.
All real numbers that are less than negative three.
All real numbers that are greater than negative three.

"All real numbers that are negative three or greater" because ≥ means 'greater than or equal to' in this case.

Step-by-step explanation:

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;

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
