So you make your equation 4x+20+40=180.
Add like terms and get 4x+60=180.
Subtract 60 from both sides, get 4x=120.
Divide boths sides by 4, get your answer of x=30.
Hope this helps

Answer:
0.0778, 0.1789,0.0250
Step-by-step explanation:
Given that μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5
(Right tailed test)
To find p value:
a) Z = 1.42: p = 0.077804
=0.0779
b) z = 0.92
p value = 0.1789
c)z= 1.96
p value = 0.0250
