Answer:
Select the correct answer.
Scientists studying biodiversity of amphibians in a rain forest have discovered that the number of species is decreasing by 2% per year. There are currently 74 species of amphibians in the rain forest. Which logarithmic function models the time, , in years, it will take the number of species to decrease to a value of n?
The answer is D.
Step-by-step explanation:
Answer:
60.0735651 degrees
Step-by-step explanation:
So the hypotenuse is 50 and the vertical leg is 13
For the angle, you need to find the sine (opposite and hypotenuse)
sin(x) = 13/50
x = asin(13/50)
x = 60.0735651
Hey there, all you do is multiply 20 by 20, 20×20=400. Therefore, the answer is 400 square feet.
13, each term is the sum of two preceding ones.
<u>Answer:</u>
The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744
<u>Solution:</u>
Total number of coils = number of good coils + defective coils = 88 + 12 = 100
p(getting two good coils for two selection) = p( getting 2 good coils for first selection )
p(getting 2 good coils for second selection)
p(first selection) = p(second selection) = 
Hence, p(getting 2 good coil for two selection) =
