Set the factor '(4 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Divide each side by '-1'. x = 4 Simplifying x = 4
Easy answer
Its 0
I hope it's correct Good luck...

Answer:
dependent-samples t test
Step-by-step explanation:
Here we want to test the effect of game Dance Dance Revolution (DDR) on heart rate.
The hypothesis is
![H_0:\mu_d=0 vs H_a:\mu_d\neq 0](https://tex.z-dn.net/?f=H_0%3A%5Cmu_d%3D0%20%20%20vs%20H_a%3A%5Cmu_d%5Cneq%200)
where,
![\mu_d=\frac{\sum di}{n} di = Xi-Yi](https://tex.z-dn.net/?f=%5Cmu_d%3D%5Cfrac%7B%5Csum%20di%7D%7Bn%7D%20%20%20di%20%3D%20Xi-Yi)
Where Xi = heart rate before playing the game Dance Dance Revolution (DDR)
Yi = heart rate after playing the game Dance Dance Revolution (DDR)
This test is paired t-test( dependent sample t test).
To measure the effect of experiment. (before - after condition)
