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:
Exact form is 
the decimal form is 5
Step-by-step explanation:
Answer:
1. 8.4 in 2. 33.6
Step-by-step explanation:
Distribute the 2 into the 2x and -y
Then add “like terms” which are 3x and 4x... 3y and -2y
Which then becomes 7x+y
There are no more “like terms” so that is your final answer
Y=2/3x-3. Follow the formula y=Mx+b. M is the slope, and b is the y intercept.
