Answer:
The Probability of randomly picking the third species=0.316
Step-by-step explanation:
In a bed of mussels on the coast of California in which five species live,
The Abundance of each Species are 100, 500, 998, 12, and 1548
Total Value=100+500+998+12+1548=3158
Abundance of third Species=998
Probability
Probability (randomly picking the third species) 
=
=0.316
Answer:
y = 12x-6
Step-by-step explanation:
y=mx+b
y = 12x-6
Answer:
The perpendicular equation is y = -3x -21
Step-by-step explanation:
Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.
To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.
First let's simplify the equation.
-5 + x = 3y (divide by 3 on both sides to get y by itself)
-5/3 + 1/3x = y or y = 1/3x + 5/3
The exact opposite of this slope would be -3.
Now plug in the point you were given so that we can find the y-intercept.
6 = -3(-9) + b (b = y-intercept)
6 = 27 + b (subtract 27 on both sides)
-21 = b
So the perpendicular equation looks like this.
y = -3x -21
The last answer...
At time 0, the velocity is 6.
When the velocity is 0, the time is 8
Answer: 
Step-by-step explanation:
Observe the picture attached.
Find the value of "x" and "y" using the Pythagoren Theorem:
If you solve for "a":
Where "a" is the hypotenuse and "b" and "c" are the legs.
In this case, for "x" you know that:
Then, the value of "x" is:
For "y" you can see that:
Subsituting values and solving for h, you get:
