A residual is a measure of how well a line fits an individual data point. Testing the two other points can really help to see how well the line fits.
Answer:
24
Step-by-step explanation:
Multiples of 16 are 
Find product of each of the multiple of 16 until a number is obtained, the product of whose digits is a multiple of 12.
Here, 24 is a multiple of 12.
So,
24 is the least positive integer such that it is a multiple of 16 and the product of its digits is a multiple of 12.
The answer is:
Justin weighs 165 pounds.
Greg weighs 180 pounds.
If:
j - Justin's weight
g - Greg's weight
Then the system of equations is:
j + 15 = g ⇒ g = j + 15
1/2g = j - 75 ⇒ j = 1/2g + 75
We can replace j in the first equation:
g = <span>1/2g + 75 + 15
g - 1/2g = 90
1/2g = 90
</span>⇒ g = 90 ÷ 1/2 = 180
<span>
Thus, Greg weighs 180 pounds.
Now, using the first equation, we will calculate Justin's weight:
</span>j + 15 = g ⇒ j = g - 15
g = 180
Thus
<span>j = g - 15 = 180 - 15 = 165
</span>
Therefore, <span>Justin weighs 165 pounds.</span>
Answer:
B. 8.4
Step-by-step explanation:
y=1.8x+1.2
x= weeks
y= pounds lost
Sub in for weeks
y=1.8(4)+1.2
y=8.4
