Answer:
Step-by-step explanation:
Given that X is binomial with n = 13 and p = 0.30
Pdf of x is
f(x) = ![13Cx (0.3)^x (0.7)^{13-x}](https://tex.z-dn.net/?f=13Cx%20%280.3%29%5Ex%20%280.7%29%5E%7B13-x%7D)
a) f(0) = P(x=0)
=0.00969
= 0.01
b) f(12) =
4.83(10^-6) ~0.00
c) ![P(X\leq 1)\\=0.06366\\=0.0637](https://tex.z-dn.net/?f=P%28X%5Cleq%201%29%5C%5C%3D0.06366%5C%5C%3D0.0637)
Answer: 1780527
<u>Multiply</u>
1.78×1000000=?
Move the decimal to the right 6 times.
1.78 > 17.8 > 178. > 1780. >17800. > 178000. > 1780000.
1.78×1000000=1780000
<u>Add</u>
527+1780000=1780527
-2x+x-4=-7 , -1x=-3, x=3. y=3-4, y=-1
It 7854
It will stay the same because the number after the decimal is 2 and 2 is least then 5 so it will all be zero
If the number is 5 of biger it will add up to 1
Ex: 246.810
It will be 247.000
The radius is half the diameter, so the formula would be r=d divided by 2
