Two students write the following expressions to answer an exercise: 7 + 4(5 – 3)2 + and 8 + (5 – 3)24 + 7

a. Simplify the two expressions. List each step you use.

b. Explain the similarities in the steps.

C. Make up another expression that uses the same numbers and operations, but
has a different value. Then simplify the expression, listing each step.

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
