Answer:
The four digit numbers are from 1000 to 9999
The number of four digits which are not divisible by 4 means 4 goes into them with a remainder
The number of four digit numbers 9999 inclusive which are not divisible by 4 are
<h3>6,750 numbers</h3>
Hope this helps you
Okay, so supplementary angles = 180 degrees.
Starting equation : 4y + 7 + 9y + 4 = 180
Combine like terms : 13y + 11 = 180
Subtract 11 from both sides : 13y = 169
Divide 13 from both sides : y = 13
Insert y value into original m<2 equation : 9(13) + 4
Solve : 121 degrees
If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.
4(13) + 7 = 59
59 + 121 = 180
Yo sup??
2x-6>12
2x>18
x>9
therefore solution set is
x belongs to (9,infinity)

Answer:
a) P(1) = 0.1637
b) 
c) E(x) = 0.2
Step-by-step explanation:
If X follows a poisson distribution, the probability that a disk has exactly x missing pulses is:
Where m is the mean and it is equal to the value of lambda. So, replacing the value of m by 0.2, we get that the probability that a disk has exactly one missing pulse is equal to:
Additionally, the probability that a disk has at least two missing pulses can be calculated as:
Where 
.
Then, 
and 
are calculated as:
Finally, In the poisson distribution, E(x) is equal to lambda. So E(x) = 0.2
