Answer:
x = 6
Step-by-step explanation:
The parallel lines divide the side lengths proportionally.
21/14 = (x+3)/x
1.5 = 1 +3/x . . . . perform the division
0.5 = 3/x . . . . . .subtract 1
x = 6 . . . . . . . . . multiply by 2x
Answer:
Step-by-step explanation:
Andi needs yards of fabric for a project.
Andi needs more of Fabric.
Just do
9/8=1.125
Then
9*.125=10
The expected length of code for one encoded symbol is
where is the probability of picking the letter , and is the length of code needed to encode . is given to us, and we have
so that we expect a contribution of
bits to the code per encoded letter. For a string of length , we would then expect .
By definition of variance, we have
For a string consisting of one letter, we have
so that the variance for the length such a string is
"squared" bits per encoded letter. For a string of length , we would get .
A. # from sample who responded "yes"
<span>b. yes/no case, fixed # of trials, independence , p ≈ constant </span>
<span>c. using a binomial calculator, P[x ≤ 185] = .9219 <------ </span>
<span>d. E[x] = 500*0.4 = 200 </span>
