use a ti 84 or something
y hat= 5.425x + 76.406
r= 0.78598
the value of r shows a linear strong positive relationship between hours studied and test score
x=4 yhat= 98.106
Answer:
9 hours
Step-by-step explanation:
12 people take 15 hours to complete one job. First let's ask how long it would take 18 people working at the same rate to complete the same job? We can use proportions to answer this
Now we know that one job takes 18 people 22.5 hours, so 2/5 of the job would take
The answer is 0.51 because 6 is the closest to 10 so we add 1 to the 0 in the 2nd place and get 1 :) Hope This Helps! :) :D Please give this thanks and the brainiest answer/crown. :) PREEETYYY PLEASE :) :):D xD
