There are 5 data values.
Mean = (22 + 37 + 49 + 15 + 83) / 5 = 41.2
You can't, the K cancels itself out. There is no solution to this
Answer:
Serina should have solved for x in the second equation because it has a coefficient of 1.
Step-by-step explanation:
we have
----> equation A
---> equation B
we know that
To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A
so
----> equation C
substitute equation C in equation A

solve for y

Find the value of x
substitute the value of y in the equation C

The solution is (3,4)
therefore
Serina should have solved for x in the second equation because it has a coefficient of 1.
