Answer: C.156
Step-by-step explanation:
Given: Total seashells = 160
mean = 120
population standard deviation = 26 grams
The probability that the seashells weigh at least 68 grams :-'
Total seashells weigh at least 68 grams = 0.9772 x 160 = 156.352≈ 156

Answer:
Cost function:
Revenue function
Profit function
Dozens needed for a specific profit P
If 150 dozen cookies are sold the profit is negative, so the business is loosing $322.
Step-by-step explanation:
We can list the costs as:
- Fixed monthly cost, $790/month.
- Variable costs, $0.24/cookie, which are (12*0.24) = $2.88 a dozen.
Then, we can write the cost function C(x) as:
being C(x): the monthly cost and x: the number of dozens produced per month.
The revenue can be calculated as the price ($6 a dozen) multiplied by the number of dozens x:
The profit can be calculated substracting the total cost C(x) from the revenue R(x).
The number of cookies (in dozens) that must be produced and sold for a monthly profit can be calculated from the previous equation for P(x).
For a monthly profit P, the number of dozens that need to be sold are:
If 150 dozen cookies are sold, the profit made is:
The profit is negative, so the business is loosing $322.
Answer: Last Option is correct.

Number of yellow marbles = 8
Number of green marbles = 9
Number of purple marbles = 3
Number of red marbles = 5
So,
Probability that there is atmost one purple marble is given by
Hence, Last Option is correct.
