Answer:
Step-by-step explanation:
The first step to solve this question is to analyze the given sequence.
We can notice that the difference between 8.5 and 7.15 is
And again the difference between the second and the third term is :
One way to describe all the numbers in the sequence is by using a formula.
We can write :
Given the sequence 
with 
∈ I
For example :
which verifies our original sequence.
We can obtain any term we want of the sequence.
Some of the terms that complete the sequence are :
Answer:
Standard deviation = 0.547
Step-by-step explanation:
Given the data
$5 for spade
$10 for any club
$20 for an ace club
Lets assume Probability of getting these cards to be
0.5, 0.20 and 0.30
Therefore, mean would be
Summation (PX) = 5×0.5 + 10×0.2 +20×0.3
Summation (PX)/n= 10.5/35 = 0.3
Standard deviation = √0.3
Standard deviation = 0.547
If p=50, then 50=4k-10
4k=60
k=15
It's decreasing by 5 1/2 each time, so:
<u><em>24 1/2, or 24.5</em></u>
Answer:
3
Step-by-step explanation:
So all of them have a theretical probability of 1/5. Now to determine the experimental propability. (1=6/25, 2=2/25, 3=5/25 or 1/5, 4=4/25, 5=8/25)
Three has an experimental propability of 1/5, which is the same as its theretical propability.
