Standard deviation I'd say
Total seats=15+19+23+27+31+35+39+43+47+51+55+59+63+67+71+75+79+83+87+91+95+99+103+107+111+115+119+123+127+131+135+139+143+147=2754 seats
Answer:
x = - 3
y = 4
Step-by-step explanation:
x + y = 1 | (-3)
x + 3y = 9
- 3x - 3y = - 3
x + 3y = 9
_____________
- 3x + x = 9 - 3
- 2x = 6
2x = - 6
x = - 3
- 3 + y = 1
y = 1 + 3
y = 4
Answer:
X=4
Step-by-step explanation:
-2x+1=-4x+9 Firstly subtract 1 from each side
-2x+1-1+-4x+9-1 Simplify by subtracting
-2x=4x+8 Add 4x to both sides
-2+4x=-4+8+4x Simplify by combining like terms
2x=8 Divide both sides by the same term
2x/2=8/2 Divide the numbers
x=4
Final answer: X=4
Enjoy! ^^
