You can solve mean by adding up all the numbers then dividing it by the number of numbers there are.
You can solve the median by putting all of the numbers in order and then crossing off one in the beginning then crossing off one at the end. You can continue that until you get to one number in the middle.
You can solve the mode by looking for the most frequent number. That's the mode. You can remember that by looking at the MO and remember most often.
I hope this helps :-)
8.525 is rounded to 8.53 because the 5 rounds up so the 2 turns into a 3
Answer:
what does -4,-3,-2,-1 implies?
Answer:
(x, y) = (-4, 15)
Step-by-step explanation:
The two equations have the same coefficient for y, so you can eliminate y by subtracting one equation from the other. Here the x coefficient is largest for the first equation, so it will work best to subtract the second equation.
(3x +y) -(2x +y) = (3) -(7)
x = -4 . . . . . . . . simplify
Now, we can find y by substituting this value for x.
2(-4) +y = 7
y = 7 +8 = 15 . . . . . add 8 to both sides of the equation
The solution is (x, y) = (-4, 15).
