4(5x-20)= -20
20x-80= -20
+80 +80
____________
20x=60
_______
20
x=3
Answer:
Step-by-step explanation:
Let X be length of life of the participants in the plan.
Given that X is N(68,3.5)
We convert this to standard normal score z using

a) proportion of the plan recipients that would receive payments beyond age 75=
b) proportion of the plan recipients die before they reach the standard retirement age of 65=
c) x for 86% ceased

27 divided by 55= 0.490909 repeating

Answer:
volume = 150.9m³
Step-by-step explanation:
in order to find the volume ,in cubic meter ,of a cylinder with a height of 3 meters and a base radius of 4 meters ,to the nearest theths place wee apply the formular for finding the volume of a cylinder which is πr²h
v = πr²h
given that
height = 3meters
radius = 4meters
volume=?
going by the formulae v= πr²h
v = π × (4)² × 3
v = π × 16 ×3
v= 48πm³
note the value of π = 22/7
v = 48 × 22/7
v = 1056/7
v= 150.87m³
therefore the volume of the cylinder to the nearest tenth place is 150.9m³
It’s 2 if I did my math right because I did it 2 tones and both of the times I got 2
