What can you say about the end behavior of the function ? A. The leading coefficient is positive so the left end of the graph goes up. B. f(x) is an even function so both ends of the graph go in the same direction. C. f(x) is an even function so both ends of the graph go in opposite directions. D. The leading coefficient is positive so the left end of the graph goes down.

idk sry

step-by-step explanation:

your answer would be b

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;
