Answer:
0.48
0.52
No
Yes
Step-by-step explanation:
Result of experiment :
Point up = 48
Point down = 52
Total number of trials = 100
Recall :
Experimental probability = number of outcomes / number of trials
1.)
P(Landing point up) = 48 / 100 = 0.48
2.)
P(Landing point down) = 52 / 100 = 0.52
3.)
The same result will not occur has the outcomes of trials aren't fixed.
4.) Yes, nearly the same result could occur on the second trial, as the number of possible outcubes are just 2 and the number if trials is high.
Part A.
You need two equations with the same slope and different y-intercepts.
Their graph is parallel lines. Since the lines do not intersect, there is no solution.
y = 2x + 2
y = 2x - 2
Part B.
We use the first equation as above. For the second equation, we use an equation with different slope. Two lines with different slopes always intersect.
y = 2x + 2
y = -2x - 2
In the second equation, y = -2x - 2. We now substitute -2x - 2 for y in the first equation.
-2x - 2 = 2x + 2
-4x = 4
x = -1
Now substitute -1 for x in the first equation to find y.
y = 2x + 2
y = 2(-1) + 2
y = -2 + 2
y = 0
Solution: x = -1 and y = 0
The first term is 2 and the common ratio = -8/2 = -4
S7 = 2 * (-4)^7 - 1

Just did a specific one of these; let's do the general case.
The point nearest the origin is (a,b).
The line from the origin through the point is
![bx - ay = 0](https://tex.z-dn.net/?f=bx%20-%20ay%20%3D%200)
The line we seek is perpendicular to this one. We swap the coefficients on x and y, negating one, to get the perpendicular family of lines. We set the constant by plugging in the point (a,b):
![ax + by = a^2 + b^2](https://tex.z-dn.net/?f=ax%20%2B%20by%20%3D%20a%5E2%20%2B%20b%5E2)
![ax + by -( a^2 + b^2) = 0](https://tex.z-dn.net/?f=ax%20%2B%20by%20-%28%20a%5E2%20%2B%20b%5E2%29%20%3D%200)
That's standard form; let's plug in the numbers:
![4 x - 4 y - 32 = 0](https://tex.z-dn.net/?f=4%20x%20-%204%20y%20-%2032%20%3D%200%20)
![x - y - 8 = 0](https://tex.z-dn.net/?f=%20x%20-%20y%20-%208%20%3D%200)
