Answer:
If you wanted to test, using a 5% significance level, whether or not a specific slope coefficient is equal to one, then you should subtract 1 from the estimated coefficient, divide the difference by the standard error, and check if the resulting ratio is larger than 1.96 .
Option B is the correct answer.
Step-by-step explanation:
If you wanted to test, using a 5% significance level, whether or not a specific slope coefficient is equal to one, then you should subtract 1 from the estimated coefficient, divide the difference by the standard error, and check if the resulting ratio is larger than 1.96.
Option B is correct because after subtracting it from 1, it will become a standardized test if the slope is equal to 0 or not.

Answer:
Area shaded portion = 16/3 π - 8√3
Step-by-step explanation:
The shaded portion consists of 2 equal segment
∵ Two circles have the same radii = 4
∵ The the length of the common chord of the two circles = 4
∴ The central angle of each segment = π/3 (60° equilateral Δ)
∵ Area segment = area sector - area Δ
∵ Area sector = 1/2 r²Ф = 1/2 × (4)² × π/3 = 8/3 π
∵ Area Δ = 1/4 s² √3 = 1/4 × (4)² × √3 = 4√3
∴ Area segment = 8/3 π - 4√3
∴ Area shaded portion = 2(8/3 π - 4√3) = 16/3 π - 8√3
Answer:
1. false; they are only skew if they have no congruency or similarity to the other segment
2. true
3. true
4. false; one is vertical and one is horizontal
5. true
6. false; they are not in the same locations on the cube
Step-by-step explanation:
7. m1 is 45 becuase it is alternate interior angles with b
m2 is 135 because the pair needs to add up to 180
