For the equation b=2a+4, a and b are integers. The following three assumptions can be made about a and b for the equation above.
Ifa>0,thenb>0.
Ifa=0,thenb≠0.
Ifa<0,thenb<□.
What number is missing from the expression b<□ in the third assumption?

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;

if the probability is 1/12, 75 people will receive a $25 gift card
