Answer:
1. what is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.

80/40=2
Therefore the common ration is 2
8*(1/x) = 4*(1/8)
8/x = 4/8
64 = 4x
x = 16
Answer: about $6.90
Step-by-step explanation: 106% of 3.35
100% of 3.35 is 3.35
6% of 3.35 is 0.201
Add them together and you get 3.551
When you round to the nearest cent, you get $3.55
After add 3.55 to 3.35 and you get $6.90
Answer: 256 CAD
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the price in US dollars of the iphone (320) and multiply it by 0.80 ( Canadian dollar to US dollar exchange rate)
Mathematically speaking:
Since:
$1 US = 0.80 CAD
$320 x0.80 = 256 CAD
