51 because you find the area of both rectangles then add them

51m^2

Step-by-step explanation:

First, separate the shape into two, the bottom half of the shape would have an area of 18 square meteres because the sides are 6 meters and 3 meters.  You would find the area by multiplying those two sides.

For the top half of the shape, you would multiply the two sides as well and add teh totals together. The one side is clearly 3 meters, but to find the otehr side you would add 5 + 3 + 3 which would give you 11.

11 x 3 = 33

6 x 3 = 18

18 + 33 = 51

answer: i believe it’s 245.04

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;
