I really need help with this is u answer it correct i can give u the crown .

93.6

Step-by-step explanation:

Andre:

6*10.4= rectangle area (62.4)

Triangles

(3*10.4)/2= 15.6

The two triangles are the same

62.4+(15.6*2)= total area= 93.6

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;
