I need help solving this pls help

37ft²

Step-by-step explanation:

area of traingle= 1/2★ base★height

base= 1.5+1.5+4 = 7ft

height= 6ft

so area of traingle= 1/2★7★6 = 21ft²

area of square= side★side

side of square= 4ft

so area of square= 4★4= 16ft²

total area of shape= area of traingle + area of square

= 21+16

= 37ft²

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;

i belive false if so your welcome if not well idk
