Answer:
6
Step-by-step explanation:
Answer: 30 square inches.
Step-by-step explanation: Take the equation, V=(1/3)AH
For V=Volume, A=Area of base, and H=equals the height of the triangular pyramid.
We know the area of the base is 9, and the height is 10. So, multiply 10x9. You get 90.
Now, to get the v, you divide 90 by 3 to get 30. V=30.
Answer: A is correct.
Explanation:
We can see f(x) is piece wise function and break at point x=2
When x<2
f(x) is parabolic whose y-intercept (0,4)
So, 
When 
f(x) is linear with slope 1
So, 
A is correct option according to given graph.

Step-by-step explanation:
y=4x+5+x
y=5x+5
Answer: Hence, Probability of more than 1 death in a corps in a year is 0.126.
Step-by-step explanation:
Since we have given that
Mean for a poisson distribution (λ) = 0.61
Number of years = 20 years
We need to find the probability of more than 1 death in a corps in a year.
P(X>1)=1-P(X=0)-P(X=1)
Here,

So,
P(X>1)=1-0.543-0.331=0.126
Hence, Probability of more than 1 death in a corps in a year is 0.126.
