The table shows the estimated number of deer living in a forest over a five-year period. are the data best represented by a linear, exponential, or quadratic model? write an equation to model the data.
this is the table :
year estimated population
0 98
1 77
2 61
3 48
4 38

a. quadratic; y=0.79x^2 + 98

b. exponential; y=98 * 0.79^x

c. quadratic; y=98x^2 +0.79

d. linear; y=0.79x+98

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

What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

What are the constants in this expression? -10.6+9/10+2/5m-2.4n+3m
