Mercury poisoning is dangerous overload of mercury within the body. A major source of mercury within the body, A major source of

mercury poisoning is consuming fish that contain mercury. Certain fish are more prone to having higher levels of mercury than others. The pie chart shows the distribution of four breeds of fish at a hatchery. The hatchery has approximately 6,000 fish. A biologist from the Centers for Disease Control and Prevention randomly test 5% of each breed of fish for mercury content. Her findings are shown in the following table. Based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level?
A) 0.001
B) 0.004
C) 0.02
D) 0.08

Answer:

  D)  0.08

Step-by-step explanation:

The pie chart shows that of the 6000 fish in the hatchery, 1/4 of them, or 1500 fish are salmon. A 5% sample of that population will be ...

  0.05 × 1500 fish = 75 fish

If 6 of these have dangerous levels of mercury, the probability of randomly choosing a contaminated fish from the test group is ...

  6/75 = 8/100 = 0.08

The rightmost column is the product shown in the middle column. From top-to-bottom, those numbers will be 83.1, 831 (given), 8310.

The middle column is a re-write of the first column and is equal to the third column. You can figure the numbers there from either direction. In the center row, you need 8.31 × ___ = 831. It should not be difficult for you to figure out the number in the blank is 100. (It is also the power of 10 between 10 in the first row and 1000 in the third row.)

The divisor in the first column is the inverse of the multiplier in the second column. 0.1 = 1/10, 0.01 = 1/100, and in the third row, 0.001 = 1/1000. The missing number in the first column is 0.001.

_____
The four missing numbers are 83.1, 100, 0.001, 8310. (top to bottom, left to right)

A company produces jam in three flavors: strawberry, raspberry, and grape. Each flavor is sold in 200-gram and 400-gram jars. Th
s344n2d4d5 [400]
Given that t<span>he 200-gram jars are priced at $3 each, and the 400-gram jars are priced at $5 each. From the table, there were 1,250 jars of 200gm and 1,100 jars of 400gm strawbery jam sold, thus, the revenue from the sales of strawberry jam is given by 3(1,250) + 5(1,100) = 3,750 + 5,500 = $9,250.

From the table, there were 1,150 jars of 200gm and 900 jars of 400gm raspberry jam sold, thus, the revenue from the sales of raspberry jam is given by 3(1,150) + 5(900) = 3,450 + 4,500 = $7,950.

From the table, there were 950 jars of 200 gm and 1050 jars of 400 gm grape jam sold, thus, the revenue from the sales of grape jars is given by 3(950) + 5(1,050) = 2,850 + 5,250 = $8,100.

Therefore, among the three flavors, raspberry jam earned the least revenue for the company.</span>
