Determine whether the system of equations has one solution, infinite solutions, or no solution:
3s =-18r + 15
12r + 2s=10
O infinite solutions
O one solution
o
O no solution

it has infinite solutions

Step-by-step explanation:

if you simplify the 1st equation you get that s=-6r+5. you substitute that in the 2nd one and it is equal to 12r+2*(5-6r)=10. when u simplify you get 10=10

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
