from 40 bulbs tested by a quality controller, 3 are faulty calculate the expected number of faulty bulbs in a box of 500
Answers
Out of 40 bulbs, 3 were faulty.
3/40 were faulty
out of 500 bulbs, 'x' were faulty.
x/500 were faulty
cross multiply 40x=1500 Divide both sides by 40 x=37.5 Since you can't have .5 of a bulb, lets round up to 38 Answer=38 bulbs
How do you find the height of a 3d object such as a triangle or a cylinder
Answers
In the case of a cylinder, one or several of the following data must be provided: the total area/lateral area and the circumference/area of the base or the area of the base and the volume. Ex: provided the circumference of the base = 10π inches, and the lateral area = 50π inches², the equation can be written as 50π ÷ 10π = 5 inches.
Well, for ANY prism (included cylinder), divide volume by area of base. h = V / B
For ANY pyramid (included cone), divide volume by area of base, then multiply it by 3. h = 3V / B
