<span>A. 0.1
The residual is the difference between the observed value and the predicted value for a data point. You obtain it by subtracting the predicted value from the observed value. So the predicted value is:
y = -0.2x + 1.9
y = -0.2*5 + 1.9
y = -1 + 1.9
y = 0.9
Therefore the residual is:
r = 1 - 0.9
r = 0.1
And the value of 0.1 matches option "A".</span>
The correct answer would be 6
Answer:
−2 degrees Celsius and −2 degrees Celsius and 2 degrees Celsius and 2 degrees Celsius
Step-by-step explanation:
Answer:

Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v =
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 =
( multiply both sides by 5 )
45 = k
v =
← equation of proportion
When w = 4 , then
v =
= 11.25
