Answer:
The standard deviation of the price she will get is $8,371.58.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The variance of the uniform distribution is given by:
The standard deviation is the square root of the variance.
Uniformly distributed between $204,000 and $233,000
This means that
So
The standard deviation is the square root of the variance. So
The standard deviation of the price she will get is $8,371.58.
Answer:
4600
Step-by-step explanation:
This is an arithmetic sequence with common difference d between consecutive terms.
d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4
The sum to n terms of an arithmetic sequence is
=
[ 2a + (n - 1)d ]
where a is the first term
here a = - 6, d= 4 and n = 50, hence
=
[ (2 × - 6) + (49 × 4) ]
= 25 ( - 12 + 196 )
= 25 × 184
= 4600
