LOOK AT THE PICTURE PLEASE

So if a maraca is 14 dollars, and you buy 12, 14 * 12 =168 dollars for maracas in total...

Claves cost 5 dollars, and there are 6 sets. So 5 * 6 = 30 dollars for claves in total

And the drum thing cost 16 dollars. so 16 * x = 16x for the price of drum

S 168 + 30 + 16x = 326?

answer: options

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;
