Answer:

Step-by-step explanation:
Given


Required

This is calculated as:

Since, it is a probability with replacement, we have:

So, we have:


In any equation there is a variable (usually x). In a quadratic equation there is a lot involved.
-B (+or-) sqrt of b^2 - 4 x A x C
________________________ divide it by
2 x A
There is usually an original equation that looks like: Ax^2 + Bx + C = 0 Use the variables from the equation to the left to fill the upper equation. (You can also look up a better formula if confused).
Answer:
1. A(1;5), B(10;23), slope of 2
2. A(10;9), B(4;0), slope of 1.5
3. A(-35/4;6), B(9;-35/6), slope of -2/3
4. A(5;18), B(25,22), slope of 0.2
5. A(2/9;1/3), B(2/3,-1/3), slope of -1.5
Step-by-step explanation:
Substitute values with correct variable and slopemis coefficient of x when x and y-int. are on 1 side, y is on other side and has coefficient of 1. Hope it works!
Answer:
200
Step-by-step explanation:
I did it in a different way I think but this is how I did it. ._.
100÷2=50
50×4=200
2c=14 (move 5 to the other side by adding it to 9)
c=7 (divide by 2 to get c on its own)
