In order to solve this, we need to select the function that meets our constraints. Since x^2 - 5 occurs when x is less than 3, and the x-value we are given is -4, we use the first function.
f(-4) = (-4)^2 - 5
f(-4) = 16 - 5
f(-4) = 11

Answer: A confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)
Step-by-step explanation:
Confidence interval for mean: Mean ± Margin of error
Given: The  online store found the mean wholesale cost of one shipment of vases was ĉ = 54 dollars, with a margin of error of 5  dollars.
A confidence interval for the mean cost (in dollars) for one shipment of vases

Hence,  a confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)
 
        
             
        
        
        
7 = 7
20 = 2 x 2 x 5
Least common multiple is 2 x 2 x 5 x 7 = 140
Other multiples are multiples of 140 = 280, 420, 560, 700
