Nikki gathered data about the length of time she spent listening to the radio and the number of commercials she heard. she organized the data in a scatter plot, where x represents the minutes spent listening and y represents the number of commercials. then she used the graphing tool to find the equation of the line of best fit: y = 0.338x − 1.387. based on the line of best fit, for approximately how many minutes will nikki need to listen to the radio to hear 20 commercials?
a=10
b=55
c=63
d=72

Option C

63

Step-by-step explanation:

Using the given equation y = 0.338x − 1.387 and since you're given the the number of commercials, you substitute this for y hence

20= 0.338x − 1.3877

20+1.3877=0.338x

0.338x=21.3877

x=21.3877/0.338=63.27514793

Rounding off, x=63. \the question says x represents the minutes spent hence the answer is 63

what is the model?

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4
