Answer:
X<-5
Step-by-step explanation:
1) open the brackets
2) take -35 to the other side with -10
where it turns to be -5X<-10+35
3) work out to find -5X<25
4) divide both sides by -5
to find X<-5
BG = 40. Equation: 4(3) + 8 + 20 = 40.
Use symmetry and find z so that probability is:
(100-39)/2
=61%
=30.5%~0.305
From the z-table:
z=-0.51
Answer: -0.51
