Answer:
4. ± 3.012
Step-by-step explanation:
Hello!
Assuming that for both variables X₁ and X₂ n₁= n₂ = 16
You need to test at 1% if the variable is significant, this means, if the slope for X₁ is different from zero (β₁≠0) using the t-statistic and the critical value approach.
The hypotheses are:
H₀: β₁= 0
H₁: β₁≠ 0
α: 0.01
The degrees of freedom "n₁-3" are determined by the number of parameters that you estimate for the multiple regression, in this case there are three "β₁" "β₂" and "δ²e"
The rejection region for this test is two-tailed, the critical values are:
±
I hope this helps!
You would just have to write it in word form but I am not sure
We know that
[area of larger triangle]=[scale factor]²*[area of smaller triangle]
[scale factor]=√[area of larger triangle/area of smaller triangle]
[scale factor]=√[49/16]-----> 7/4
Part A) <span>what is the ratio of the corresponding side lengths?
the ratio </span>of the corresponding side lengths is equals to the scale factor
the answer Part A) is
the ratio of the corresponding side lengths is 7/4
part B)what is the ratio of the perimeters?
the ratio of the perimeters is equals to the scale factor
the answer Part B) is
the ratio of the perimeters is 7/4
Answer:
Step-by-step explanation:
t=C/ c
C=quantity in a cup
c=quantity in a teaspoon
Yes it does, it is proportional because it increases by the same amount at a constant time (which is each week's paycheck). The constant is the 150. i may be wrong sorry if so.
