Determine f(0)
To solve for f(0), we make use of:

Because:
is true for 
So, we have:




Answer:
A = 100
B = 50
C = 30
Step-by-step explanation:
You can make this equation to solve:
2x+x+x-20=180
4x-20=180
+20 +20
4x=200
divide both sides by 4
200/4 = 50
x=50, B = x = 50
2x = 100 = A
x-20 = 30 = C
The correlation coefficient (r) of the height and weight is 0.40391008.
Rounded, It will be 0.4
That means that the correlation between the height and weight is a positive weak correlation.
Answer:
143
Step-by-step explanation:
x + 17 = 37
180 - 37 = 143
0.182, 0.181, 0.175. Large is the better buy because it has the lesser unit price.
