They are variables they can equal anything. it is just an example of two different fractions who's numbers are unknown.
Answer:
Step-by-step explanation:
for right-angled triangle: a^2 + b^2 = c^2
given a = 5 n b = 10
c^2 = 5^2 + 10^2
= 25 + 100
= 125
c = sqrt(125)
= 5*sqrt(5)
Hey!
so first distribute the 5 to x + 4
5x+20 = 2x + 20 + 2x
combine 2x and 2x
5x+20 = 4x + 20
Now you want the constant and variable on different sides so subtract 4x to the other side
5x - 4x + 20 = 20
1x + 20 = 20
now subtract the 20 on the 1x + 20 side to the other side
1x = 0
divide by 1
0 divided by anything is 0
So x = 0
Hope this helps!
Since the value is taken from a population, the value is a parameter.
<h3>Parameter and Statistic:</h3>
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
For this problem, the students of the class are the population, as all students are considered for the calculator of the mean, hence the value is a parameter.
