1) in first place you must Know F(X) for every value of x
F(0) = 250(0.5)^0 = 250
f(1) = 250(0,5)^1 = 250*0,5 = 125
f(2)= 250(0,5)^2= 250*0,25 = 62,5
the average is = 250+125+62,5/ 3 = 145,83
Answer:
3√2
Step-by-step explanation:
If you draw the diagonal, you have a 45°45°90° triangle.
The two legs are 3, so the hypotenuse is 3√2
The graph is given below. Then the intersection point will be (-9, 11).
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
An unknown number y is 20 more than an unknown number x.
The number y is also x less than 2.
The equations to find x and y are shown below:
y = x + 20 ...1
y = −x + 2 ...2
Add both equations, then we have
2y = 22
y = 11
Then put the value of y in equation 1, then we get
11 = x + 20
x = 11 - 20
x = -9
Then the intersection point will be (-9, 11)
