In a regression study of factors affecting learning time for a certain task (measured in minutes), gender of learner was included as a predictor variable (x2) that was coded x2 = 1 if male and 0 if female. it was found that î²ë 2 = 22.3 and s(î²ë 2) = 3.8.

an observer questioned whether the coding scheme for gender is fair because it results in a positive coefficient, leading to longer learning times for males than females?

idk u tell me

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
