Fiona buys different amounts of gas at $2.25 per gallon. She has a graph that shows the amount she should pay as a function of the amount of gas she buys.
What constraints are there on the domain of the function?

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

step-by-step explanation:

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for

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;
