Answer:
P(X=2)=0.0446
Step-by-step explanation:
If X follows a Poisson distribution, the probability p to have x pits in 1 cm2 is calculated as:
Where m is the mean of pits per cm2, so, replacing m by 6 pits per cm2, we get that the probability is equal to:
Now, the probability P(x=2) that there are 2 pits in a 1 cm2 is calculated as:
Answer:
3 units
Step-by-step explanation:
Hello
The sphere volume is:
(4/3)*Pi*r^3
then
36 = (4/3)*Pi*r^3
36/[(4/3)*Pi] = r^3
8,5 = r^3
r = 3

Answer:
x = 10 and BD = 74
Step-by-step explanation:
AE and CE are equal, so we can set those 2 values equal to each other to find x.
3x + 7 = 37
3x = 30
x = 10
BD will be equal to AE + CE because that is a property of the rectangle.
So AE + CE = 37 + 37 = 74.
BD = 74
Answer: y=3 x=4
Step-by-step explanation:
Its a rectangle so the 2 horizontal sides are even and the vertical sides are even. So, since one side is 10, the other side has to be 10. So, 2y+4 = 10. subtract 4 from each side getting 2y = 6. divide by 2 to get the y by its self and you get y = 3.
For the horizontal side, 10 + 2x = 18. subtract 10 from each side. 2x = 8 divide by 2. x = 4
