Answer:
Probability of more than 1 death in a corps in a year
12.52%
Probability of no deaths in a corps over 7 years
1.40%
Step-by-step explanation:
If the data collected follow a Poisson distribution with mean 0.61, then
Probability of k deaths in a year is
The probability of more than 1 death in a corps in a year would be
(1)
But the Taylor series around 0 for the exponential function is
So,
and
Replacing in (1), we obtain
or 12.52%
b)
The probability of 0 deaths in one year is
As the events are independent, the probability of 0 deaths over 7 years is the product of P(0) by itself 7 times:
or 1.40%
The generic equation is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = (0-1) / (4-3)
m = (- 1) / (1)
m = -1
The ordered pair is:
(xo, yo) = (4, 0)
Substituting values:
y-0 = -1 * (x-4)
y = -x + 4
Answer:
y = -x + 4
option 1
Answer:
Step-by-step explanation:
When you plug y into the original equations, it comes out that the two numbers are 6 and 25. You can check your work because 6+25 = 31 and 6*25 = 150.
