b)8
c)16
d)18
i need the answer plz i would really appreciate it geometry it’s very hard

8

Step-by-step explanation:

Ok... So this is about as simple as it gets. If you look at BE and ED, you can see the little red lines on them. That means that they are congruent. So if BE=8, then so does ED.

If you need help with anymore problems (or my explanation just doesn't make sense) just let me know.

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;
