Nancy measures the amount of strawberry juice that is added to her two-liter seltzer water. The average is two tablespoons, but she allows one teaspoon more or less. What is the mean?

A. one teaspoon
B. two tablespoons
C. one tablespoon
D. two liters
E. three tablespoon

The mean for Nancy is 2 tablespoon

Step-by-step explanation:

Average tablespoon to be added to 2 litres of water=  2 tablespoon

ceiling value (bigger of the two values)= one more than average tablespoon= (2+1) 3 tablespoon

Floor value (smaller of the two values)= one less than average tablespoon= (2-1) 1 tablespoon

Mean value of the tablespoon= (floor value+ceiling value)/2

Substituting the values of floor value and ceiling value

Thus the value is 2 tablespoon

Mean tablespoon allowed by Nancy in the two litres of seltzer water is 2 tablespoon.

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
