For several years, Graham has gathered data on students who own a computer and on their performance on a typing-speed test. He creates the linear model y = 3.8x + 17.4 where y represents the typing speed, in words per minute, of a student and x represents the number of years the student has owned a computer. According to Graham’s model, what is the approximate speed of a student who has owned a computer for three years?
21 words/min
29 words/min
56 words/min
64 words/min

Respuesta :

Answer:

B 29 words/min

Step-by-step explanation:

I just put it into desmos and went to the third number line

Based on the Graham's model, a student who has owned a computer for three years will have an approximate speed of 29 words / min.

What is the approximate speed according to the Graham model?

The Graham model is:

y = 3.8x + 17.4

x is the number of years so the approximate speed is:

= 3.8(3) + 17.4

= 11.4 + 17.4

= 28.8

= 29 words per min
