Jeannine runs for 45 minutes every day for exercise. it takes her 8 minutes to run a mile, and she spends 5 minutes stretching halfway through the run. if x represents the number of miles she runs, then 8x + 5 ≤ 45 represents the time she runs each day. what is the fewest number of miles jeannine must run to complete her daily

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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;
