The percentage is 25, a trick you can use to find the percentage when you have a decimal is to move the decimal point two places to the right like if you have .25 you move the decimal point two places to the right. another example is .38, you move the decimal point two places to the RIGHT and get 38 which is the percentage :)
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.
It is 2x-1 that is your awnser
Answer:
h = 12
Step-by-step explanation:
3053.63=πr^2h
Let r=9 and approximate pi as 3.14
3053.63=3.14 ( 9)^2 h
3053.63=3.14*81*h
3053.63=254.34h
Divide each side by254.34
3053.63/254.34=254.34h/254.34
12=h
If the weight of the boxes that Caleb lifted is equal to c, then each box that Sergio lifted weighed c + 10. The total number of pounds that Sergio lifted is equal to the product of the number of the boxes and the weight. That is,
12(c + 10)
Thus, the answer is letter C.
