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%
5x=10

Answer:
the desired equation is y = (-3/2)x + 3
Step-by-step explanation:
Two points through which the graph passes are (0, 3) and (2, 0). (0, 3) is the y-intercept. Thus, the slope-intercept equation y = mx + b becomes
y=mx + 3. Borrowing the coordinates of (2, 0) and substituting them into this last result, we get
0 = m(2) + 3,
which, after having been solved for m, gives us m = -3/2
and so the desired equation is y = (-3/2)x + 3.
Answer:
The answer is 40a+14c
Step-by-step explanation:
Step 1: Open the brackets
7a-9c+12a+33c+21a-10c
Step 2: Group all the like terms
Like terms are terms with similar variables, for example;
(7a, 12a, 21a) are all like terms since they have a common variable (a)
(-9c, 33c,-10c) are also like terms since they have a common variable (c)
Step 2: Solve
(7a+12a+21a)+(33c-10c-9c)=40a+14c
The answer is 40a+14c
