If we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.

<h3>What is a Discrete variable?</h3>
  • A discrete variable is one whose value can be determined by counting.
  • A continuous variable is one whose value can be determined through measurement.
  • A random variable is one whose value is the numerical result of a random phenomenon.
  • The possible values of a discrete random variable X are countable.
  • As an example, It is a type of Discrete variable if we asked people their age and you collected it as 5, 6, 10, 11, 15, 16, 20, 21, 25, 26, and older.
  • There are two types of quantitative variables: discrete variables and continuous variables.
  • Counts are represented by discrete variables (e.g. the number of objects in a collection).
  • Continuous variables represent quantifiable quantities (e.g. water volume or weight).

Therefore, if we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.

If you add Natalie's age and Fred's age, the result is 42. If you add Fred's age to 3 times
Alla [95]

Answer:

N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28

Step-by-step explanation:

Using variables N=natalies age and F=Freds age

N+F=42 ----> N=42-F (take this and plug it into the other equation)

F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]

-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]

So N+28=42 or N=14.

A backpack that normally sells for $39 Is on sale for 33% off. Find the amount of the discount and the sale price
Nataliya [291]
To get the price, you have to multiply the amount by the percent it would become.

100% of 39 is 39
It is 33% off
100 (1.00) - 33 (0.33) = 67% (0.67)

Remember, the percent is a decimal because it is part of a whole (1).

39*0.67=$26.13.

3x+112=5x+100 what is the answer I don't get it
slega [8]
Reorder the terms
112 + 3x = 100 + 5x
112 + 3x + (-5x) = 100 + 5x + (-5x)

Combine the like terms
5x + (-5x) = 0
112 + (-2x) = 100 + 0
112 + (-2x) = 100

112 + (-112) + (-2x) = 100 + (-112)
Combine like terms again
112 + (-112) =0
0 + (-2x) = 100 + (-112)
100 + (-112) = (-112) = (-12)
-2x = -12
-12 / -2 = 6
x = 6 <span>✓</span>

Check your work
3 * 6 + 112 = 130
5 * 6 + 110 = 130
130 = 130 ✓
