Let's actually find the line of best fit...
m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)
m=(11*836-130*55)/(11*385-3025)
m=2046/1210
m=93/55
b=(Σy-93Σx/55)/n
b=(55Σy-93Σx)/(55n)
b=(7150-5115)/(55*11)
b=185/55, so the line of best fit is:
y=(93x+185)/55
A) The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.
Which means that those who do not practice at all will win about 3.36 times
B) y(13)=(93x+185)/55
y(13)≈25.34
So after 13 months of practice one would expect to win about 25.34 times.
Answer:
7 is the right aswer
Step-by-step explanation:
Answer:
x =(4-√24)/4=1-1/2√ 6 = -0.225
or
x =(4+√24)/4=1+1/2√ 6 = 2.225
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
if x=6, 6-3=3 , so it is possible if x is 6
Answer:
Step-by-step explanation:
To obtain the graph of f(x)-1 you only need to move down one unit the graph of f(x). What do you think is the best answer? I think is 4.
