His investment will reach 14,100 after 47 quarters or 11 years and 9 months
Answer:
To do this in my head: 60km = 40km+20km
So 40km/8km = 5
40 k is approximately 5x5miles = 25 miles
20k is half that or 12.5 miles
60 is about 25+12.5 miles
or 37.5 miles
Volume of cylinder = πR².H
Volume Sphere: =4/3πR³
Volume of cylinder = Volume Sphere (given), then:
πR².H = 4/3πR³
Simplify==> R².H = (4/3)R³==> H = (4/3)R===> R=3H/4
Answer:
Option c) Sample space
Step-by-step explanation:
Given that a family has two children.
Let M represents male, and F represents female.
In probability theory, the sample space (also called sample description space or possibility space) of an experiment or random trial is the set of all possible outcomes or results of that experiment. A sample space is usually denoted using set notation, and the possible ordered outcomes are listed as elements in the set. It is common to refer to a sample space by the labels S,
, or
(for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite.
Let S be the sample space of the given data.
Here the sample space is typically the set {male, female}, commonly written 
ie, S is the set
or 
For the gender of the children, corresponding sample space would be
, commonly written as

S is the set
