Step-by-step explanation:
To solve a system of equations, we can add the two equations and solve for one of the remaining variables -- let's try to eliminate the variable when we add the two equations together.
Right now, there's a term in the first equation, and a term in the second equation, so if we add those together, we'll be able to eliminate the variable altogether and solve for .
However, when we also have a term in the first equation and term in the second equation, so adding these together will also eliminate the term, leaving a on the left-hand side of the equation.
If we add the two numbers on the right side of the equation, we get , which does not equal , meaning there are no solutions to this system of equations.
(3p)(3p) or 3p x 3p. Cause the exponent means 3p times 3p
Answer:
10
Step-by-step explanation:
Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.
The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:
Coefficient of variation = mean / standard deviation
Coefficient of variation = 50 / 5
Coefficient of variation = 10
