Question 4 Multiple Choice Worth 4 points)
(05.07 MC)
A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table:
Year
Annual Salt Intake
(grams)
2012 3.554
2013 3,598
2014 3 603
2015 3,655
2016 3.718
2017 3.794
The study found that the data after the year 2012 can be modeled by the function f(x) = 52.3x + 3.548, where x is the number of years since 2012 and f(x) is the
total amount of salt ingested in grams Describe the significance of 3.548

answer: 40.95

step-by-step explanation:

-6 is the correct option from the above given options

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
