Answer:
Step-by-step explanation:
The first line has a slope of -5/3 found using the points in the slope formula.
Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form

Step-by-step explanation:
(a)
P-value of income and size is 0.0003 and 0.0001 respectively. Both are less than 0.05 level of significance. So these are significant ot the model. Option D is correct.
(b)
The model is
House_size = -1.6335+0.4485*income + 4.2615*family_size -0.6517*school
Here we have income = 85600/1000 = 85.6
family_size = 6
school = 13
So the predicted house size is
House_size = -1.6335+0.4485*85.6 + 4.2615*6 -0.6517*13=53.855
the predicted house size (in hundreds of square feet) is 53.86. hence, option B is correct.
3)
Here we have income = 100000/1000 = 100
family_size = 10
school = 16
So the predicted house size is
House_size = -1.6335+0.4485*100 + 4.2615*10 -0.6517*16=75.40
Residual : observed value- predicted value = 70 - 75.40 = -5.40
Option C is correct.
Answer:
a). 1/13
There are 4 5s. so 4/52
b). 3/13
12 total jack, king, and queen. 12/52
c). 15/26
30 cards are not face cards so 30/52
