0.13 + 0.14= 0.27
0.27 ÷ 2 = 0.135
Therefore the midpt. Is 0.135
Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7
Answer:
You would usually use 3.14
Step-by-step explanation:
It kind of depends on where you are using it. In an equation, pi would be used as 3.14 and the answer would be approximated. To write it anywhere else (I dont know where else you would though), you would do the pi symbol. I hope this helps.
Answer:
c. The mean is the same as the average. The average is (6 * 5 + 7 * 4 + 8 * 7 + 9 * 10 + 10 * 4) / (5 + 4 + 7 + 10 + 4) = 244 / 30 = 8.133.
