Answer:
y = x - 7
Step-by-step explanation:
Parallel lines have the same gradient in this case 1 is the gradient.
Using the point (8,1) we can form our own equation.
1 will be y, 1 will be m, 8 will be x
All we have to do is find C in order to form the equation <em>y</em><em>=</em><em>mx</em><em>+</em><em>c</em>
1 = 1(8) + c
1 = 8 + c
C = - 7
Therefore;
<u>y = x - 7</u>
Answer:
Step-by-step explanation:
(x - 5)(x-4)
= x(x) - 4(x) - 5(x) - 4(-5)
= x^2 - 4x - 5x + 20
= x^2 - 9x + 20
The square root of a number is any number that when multiplied against itself becomes the number under symbol denoting for the square root operation.
The number 10 is the result of the square root operator applied to the number 100 because 10 * 10 = 100.
The number 10 is a natural number because natural numbers are positive integers. It is also an integer, whole number, and rational.
Hope this answer helps!
Answer:


Step-by-step explanation:
From the question we are told that:
Sample size n=9
Number of Green 
Number of yellow 
Number of white 
Probability of Green Followed by yellow P(GY) ball


Generally the equations for when n is even is mathematically given by



Therefore



Generally the equations for when n is odd is mathematically given by



b)
Probability of drawing white ball

Therefore



Therefore
![E(y)=[E(w)-1]\frac{4}{9}](https://tex.z-dn.net/?f=E%28y%29%3D%5BE%28w%29-1%5D%5Cfrac%7B4%7D%7B9%7D)
![E(y)=[\frac{9}{2}-1]\frac{4}{9}](https://tex.z-dn.net/?f=E%28y%29%3D%5B%5Cfrac%7B9%7D%7B2%7D-1%5D%5Cfrac%7B4%7D%7B9%7D)

-4,-4 - 9,-1 is the answer, i think
