Answer:
5
Step-by-step explanation:
plug everything in:
48+4h=68
-48 -48
4h=20
divide by 4 to isolate h
h=5
Answer:
688x6=4128(because you had to divide by 6 to get the mean of the 6 outliers so you do the opposite to find the total)
267x100=26700(again you had to divide by 100 to get the mean, so do the opposite to find the total)
26700-4128=22572(total after removing the outliers)
22572/94=240.13 is the mean without the outliers
Step-by-step explanation:
D 32% because 0.32 turns out to be 32%
Answer:
Owen can afford to keep and drive the car for 4 days.
Step-by-step explanation:
The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:
R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330
= $77.25d + $21 ≤ $330
This simplifies to $77.25d + $21 ≤ $330, or
$77.25d ≤ $309
Solving this by dividing both sides of the above equation by $77.25, we get
d = ($309)/($77.25) = 4
Owen can afford to keep and drive the car for 4 days.
Based on the regression line, and the data points, the sum of squared residuals is 22.
<h3>What is the sum of squared residuals?</h3>
The squared residual can be found as:
= (y - 3 + 2x)²
For point (4 , 8)
= (8 - 3 - 2(4))²
= 9
For point (2 , 5)
= (5 - 3 - 2(2))²
= 4
For point (1, 2)
= (2 - 3 - 2(1))²
= 9
The sum of squared residuals is:
= 9 + 4 + 9
= 22

The regression line = 3 + 2x has been fitted to the data points (4,8), (2,5), and (1,2). The residual sum of squares will be:
