The manager of a pizza chain in albuquerque, new mexico, wants to determine the average size of their advertised 16-inch pizzas. she takes a random sample of 25 pizzas and records their mean and standard deviation as 16.10 inches and 1.8 inches, respectively. she subsequently computes a 95% confidence interval of the mean size of all pizzas as [15.36, 16.84]. however, she finds this interval to be too broad to implement quality control and decides to reestimate the mean based on a bigger sample. using the standard deviation estimate of 1.8 from her earlier analysis, how large a sample must she take if she wants the margin of error to be under 0.5 inch?

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

the answer is 40.
