Answer:
The formula for the probability distribution is:
P(X = n) = q^(n - 1)p
= [0.2^(n - 1)]0.8
Step-by-step explanation:
This is a geometric probability distribution.
The probability of success p = 80% = 0.8
The probability of failure is q = 1 - p = 0.2
The formula is:
P(X = n) = q^(n - 1)p
= [0.2^(n - 1)]0.8
I think it is 1/9, is there another number on the right side of triangle or is it just a prentices
Answer:
The equation is y = 4x + 5
Step-by-step explanation:
To find the equation to this table, pick two ordered pairs and use the slope formula to find the slope. For this we'll use (4, 21) and (8, 37).
m(slope) = (y2 - y1)/(x2 - x1)
m = (37 - 21)(8 - 4)
m = 16/4
m = 4
Now we can use that slope along with any point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 21 = 4(x - 4)
y - 21 = 4x - 16
y = 4x + 5
