Test

175.1

Step-by-step explanation:

Find the area of the semicircle:

(pi • radius²) / 2. [Radius is half of diameter]

(3.14 • 4²) / 2

(3.14 • 16) / 2

(50.24) / 2

25.12

Find the area of the parallelogram:

(base • height)

(30 • 5)

150

Add the areas of both shapes to get total area

25.12 + 150 = 175.12, round to the nearest tenths, 175.1

Hope this helps!

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;
