Answer:
Distributive property of equality
Step-by-step explanation:
The first thing to do in an equation is to distribute.
5! Is the same as 5x4x3x2x1 and 4! Is the same as 4x3x2x1 because 4! Is in the denominator it cancels the 4x3x2x1 in the numerator and you are left with 5x(3!) witch is the same a 5x3x2x1. The answer=30
They each have $42 because 7 times 6 is 42 and combined they have $84 because 42 + 42=84.

Answer:
0.52
Step-by-step explanation:
Given the regression line :
Test score^ = 698.9 - 2.28STR
T statistic on slope Coefficient = 4.38
The standard error on slope Coefficient :
2.28 / 4.38
= 0.5205479
= 0.52
