Answer:
No. See the explanation below.
Step-by-step explanation:
No. When we have the lineal model given by:
For n observations, where y represent the dependent variable, X represent the independent variable and 
are the parameters of the model, we are assuming that 
is and independent and identically distrubuted variable that follows a normal distribution with the following parameters 
.
So then the expected value for any error term is 
So then if we find the expected value for any observation we have this:
Now we can distribute the expected value on the right by properties of the expected value like this:
By properties of the expected value 
if a is a constant and X a random variable, so then if we apply this property we got:
And if we see that'ts not the result supported by the claim for this reason is FALSE the statement.
Answer:
B
Step-by-step explanation:
3 -4 | 2
0 -1 | 7
3/2 -2 | 1
R1/3 ----> R1 (divide Row 1 by 3)
1 -4/3 | 2/3
0 -1 | 7
3/2 -2 | 1
R3 - 3/2 R1 -------> R3 (multiply Row 1 by 3/2 and subtract it from Row 3)
1 -4/3 | 2/3
0 -1 | 7
0 0 | 0
R2 / -1 -------> R2 (Divide Row 2 by -1)
1 -4/3 | 2/3
0 1 | -7
0 0 | 0
R1 + 4/3 R2 --------> R1 (Multiply Row 2 by 4/3 and add it to Row 1)
1 0 | -26/3
0 1 | -7
0 0 | 0
Answer:
1
Step-by-step explanation:
if the diameter is 2, the radius will be half of the diameter. so it will be 1. so the radius will be 1
I believe its $79. 2.00 times 21 is 42, 1.50 times 34 is 51 and 1.00 times 65 is 65. divide the sum of these three numbers and you get 79.
