Answer: I think it's 662.4
Please correct me if I'm wrong.
y = 30x + 20 is the equation
(2,5) (9,2)
Before finding slope intercept form (y=mx+b) we must find point slope form. Point slope for is y-y1 = m(x-x2) where m is slope and (x1,y1) is a coordinate pair on the line. To find slope we use the formula (y2-y1)/(x2-x1). Since we have two points given, we simply plug them in to this equation.
(5 - 2)/(2 - 9) = 3/- 7 so m = -3/7.
Now we can fill in the point slope equation using either coordinate pair provided. Will be using the one with smaller numbers (2,5). Plug your values in!
y - 5 = -3/7(x-2)
Now to get to slope intercept form you simply multiply or distribute and move over the 5.
y - 5 = -3/7x + 6/7 ---- Now add 5 or 35/7 to both sides
y = -3/7x + 6/7 + 35/7 ----- Simplify to get a final answer if y = -3/7 + 41/7 which is the second choice on the screen.
Answer:
f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)
Step-by-step explanation:
Given
The range of values is given as {0,1,2,3,4}
Because any computer can fail.
Given that the failure of the computers are independent and
The probability of failure is given as 0.0005.
Cumulative Distribution Function is the the probability that a random variable is less than or equal to a specific value
So, we'll take the binomial effect into consideration.
It is given as
f(x) = P(X ≤ x) = 4Cx * 0.0005^x * (1 - 0.0005)^(4 - x)
f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)
Answer:
25
Step-by-step explanation:
range = largest value - smallest value (123-25)
