There is only solutions to the systems of equations - y = x -2 & y = -x + 2. We can find this by looking at the slopes of each line, which is 1 and -1. They are not negative reciprocals or the same exact slope, which would give the system of equations no solutions. Since the lines are not exactly the same, the system does not have infinitely many solutions. A system of LINEAR equations cannot have two solutions, giving us an answer of only one solution. Hope this helps!
Answer:
The mean is 0.54 and the standard deviation is 0.0135.
Step-by-step explanation:
The mean is 0.54. The standard deviation is calculated using that mean:
s = √(p (1 − p) / n)
s = √(0.54 (1 − 0.54) / 1356)
s = 0.0135
989 players. each team has 43 playersvand there are 23 teams. so 43x23= 989

Answer:
u = 10
Explanation:
slope can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
We are given:
slope = -4/3
point (10,6) representing (x1,y1)
point (7,u) representing (x2,y2)
Substitute with the givens in the above rule and solve for u as follows:
slope = (y2-y1) / (x2-x1)
-4/3 = (u-6) / (7-10)
-4/3 = (u-6) / (-3)
-3 * -4 = 3 * (u-6)
4 = u - 6
u = 4 + 6
u = 10
Hope this helps :)
