In a multiple regression analysis involving two independent variables, if b1 is computed to be + 2.0, it means that multiple choice the relationship between x1 and y is significant. the estimated average of y increases by 2 units for each increase of 1 unit of x1, holding x2 constant. the estimated average of y is 2 when x1 equals zero. the estimated average of y increases by 2 units for each increase of 1 unit of x1, without regard to x2.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

the answer to your question is b.
