Answer:
The formulas are functionally the same, but 'n' (the sample size) is used instead of 'N' (the population size).
Step-by-step explanation:
The sample mean is the average value for a set of observations which is derived from a population. While the population mean is the average value for the entire set of observation belonging to a particular study of interest.
The set of observation belonging to a population is denoted by 'N' ; while the sample size is denoted as 'n' :
The mean formula is written thus :
Population mean = Σx / N
Sample mean = Σx / n
Where, x = set of values.
Answer:
Rewrite the equation as x+xyz=wx+xyz=w.
x+xyz=wx+xyz=w
Subtract xx from both sides of the equation.
xyz=w−xxyz=w-x
Divide each term by xzxz and simplif
First, let's simplify the equation.
- Apply the Distributive Property to the right hand side of the equation
- Subtract
from both sides of the equation
Since the right and left sides of the equation are equal, we know that there must be an infinite number of solutions. This means that there is an infinite amount of values that we can substitute for 
for the equation to be true.
Step-by-step explanation:
7 1/5 × 49 7/5 = 49
convert mixed numbers into improper fractions (whole number × denominator + numerator)
7 × 5 + 1 = 36
49 × 5 + 7 = 252
36/5 × 252/5 = 49
All fractions must have a common denominator
49 × 5 = 245
36/5 × 252/5 = 245/5
Add numerators
36 + 252 = 288
288/5 = 245/5
57 3/5 = 49
These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?
