Answer:
2 pounds of 1st kind and 8 pounds of 2nd kind are mixed.
Explanation:
Given:
Ten pounds of mixed birdseed sells for 8.24 per pound.
Price of the 1st variety of birdseed=5.68 per pound
Price of the 2nd variety of the birdseed=8.88 per pound.
To find :
Pounds of 1st variety of birdseed are used in the mixture=?
Pounds of 2ndvariety of birdseed are used in the mixture=?
Solution:
Let the weight of 1st kind added in mixture be n pounds.
Then weight of 2nd kind will be 10 – n pounds.
Now, total cost of mixture = cost of 1st kind birdseed + cost of 2nd kind birdseed
Weight of mixture x cost per pound = weight of 1st kind x cost per pound + weight of 2nd kind x cost per pound.
Substituting the values,
82.4 = 5.68n + 88.8 – 8.88n
8.88n – 5.68n = 88.8 – 82.4
3.2n = 6.4
n = 2
Then, weight of 2nd kind is 10 – 2 = 8 pounds.
Hence, 2 pounds of 1st kind and 8 pounds of 2nd kind are mixed.
Answer:
the customer's expected value of the cellphone insurance policy is -$38.64. (Option C)
Step-by-step explanation:
Based on the data given, 585/5000 or 11.7% of the total number policies have claims. This means, 100% - 11.7% = 88.3% have not claimed their cellphone insurance.
- In the chart, we are focusing on the customer's end because the question is asking for the customer's expected value↓
- In the chart, if the customer has no claims, then he losses his $48. However, if he has claims, he gains $32 since $80 - 48 = $32. Also, based on the data given by the company, 88.30% have no claims and only 11.7% of the customers have claims.
- To get the expected value, we will multiply -48 and 88.3% as well as 32 and 11.7%. 48 is negative because it indicates a loss.
Therefore, your Answer is -38.64
