Answer with explanation:
Gross Annual Salary of Brianna's= $ 50,676
Monthly Salary of Brianna's
$
We will use rule here,which states that, 28% of monthly income should be used for housing expenditures,and 36 % of monthly income should be used for paying Debt or Debt Purposes.
So, Maximum Monthly Rent that Brianna can pay
= 28 % of 4223
=$ 1182 (Approx)
Option C: $ 1182
Answer:
8.5
Step-by-step explanation:
We can divide this experiment in three parts.
- Before removing any white chip
- After ramoving one white chip, and before removing two
- After removing two white chips
For the first experiment, for each extraction we will always have 3 white chips and 3 red chips, becuase if we extract a red chip, then we put it back in the bag, and if it is a white chip, then the experiment ends there. The probability of taking out a white chip is 1/2.
For the second experiment, we will have always 2 white chips, and 3 red chips. So the probability of success is 2/5 = 0.4
For the third experiment, we will have always 1 white chip and 3 red chips, so the probability of success if 1/4 = 0.25.
We want to know how many extractions we need for each experiment until we pick a white chip. Note that each experiment is independent of each other, and each one has geometric distribution, the first one with probability of success 0.5, the second one with probability of success 0.4, and the third one with p = 0.25.
The total experiment, X, is the sum of this random variables, so the expected value of the total experimet is the sum of the expected value from each of its parts, lets call them, X₁, X₂ and X₃. Thus,
The expected number of draws is 8.5.
