Answer:
Number of apartment = 9
Step-by-step explanation:
Given the ANOVA result :
ANOVA ____ df ____ SS
Regression __ 1 ___ 41587.1
Residual ____ 7 ___
Total _______ 8 __ 51984.5
Number of apartment building in sample (n) :
Degree of freedom (df) = n - 1
The degree of freedom = total = 8
Hence,
8 = n - 1
8 + 1 = n - 1 + 1
9 = n
Hence, number of apartment building in sample = 9
Answer:
A. (1, -2)
B. the lines intersect at the solution point: (1, -2).
Step-by-step explanation:
A. The equations can be solve by substitution by using the y-expression provided by one of them to substitute for y in the other.
This gives ...
3x -5 = 6x -8
Adding 8-3x to both sides, we get ...
3 = 3x
Dividing both sides by 3 gives ...
1 = x
Substituting this value into the first equation, we can find y:
y = 3(1) -5 = -2
The solution is (x, y) = (1, -2).
__
B. The lines intersect at the solution point, the point that satisfies both equations simultaneously. That point is (1, -2).
For b) you already have two possibilities, since you have the intercepts.
<span>(20358, 0) and (0,15834) are two possible points, although not very likely. </span>
<span>Solve for y: y= (-7/9)x + 15834 </span>
<span>Any multiple of 9 will give whole number answers. </span>
<span>Let x= 9 </span>
<span>Then y= (-7/9)(9)+ 15834 </span>
<span>Y= 15827 </span>
<span>If you want more reasonable answers, let x= 9000 </span>
<span>Then y= (-7/9)(9000)+ 15834 </span>
<span>Y= 8834 </span>
