Answer:
The symbol used for the sample standard deviation is the 's', while the symbol used for the population standard deviation is a "sigma" or σ.
On the other hand, the sample variance comes to be the square of the sample standard deviation: s². Likewise, the the population variance comes to be the square of the population standard deviation which is: σ²
Answer:
plots: -12,0
Step-by-step explanation:
The equivalent fractions are:
2/3
20/30
30/45
First lets write an equation to help us solve this.
26.25=3x+5.25
x=7
26.25 - 5.25 = 21.
21/3 = 7.
