Answer:
E
Step-by-step explanation:
When you perform an experiment on a population, the majority of the time, you cannot use the entire population, so instead you use a sample of that population.
In this case, you mark 130 MendAliens out of an unknown population. After that you capture 90, and see that 20 are marked. You can use this to assume that for every 90 MendAliens, you marked 20, so if you calculate that as a percentage, you would get 22.22%.
This means that you marked approximately 22% of the population, when you marked those 130 MendAliens. Using basic math, we can work backwards to calculate the total population.
Percentage (%) = Sample / Total
Inserting the values we know...
22.22% = 130 / Total
Rearranging the formula, we get...
Total = 130 / 22.22%
Since we know 22.22% is actually equal to (22.22 / 100)= 0.2222
Total = 130 / 0.2222
Total = 585

Answer: 1
Step-by-step explanation:
A formula for the slope of a line is rise/run.
First let’s find the ‘rise’
To find the rise, we must look at the difference between the elevation of the points. We can find the rise by subtracting y1 from y2. 7-3=4, so the rise is 4
Run is the same concept. We must subtract x2 - x1.
2-(-2)=2+2=4
So the rise is 4 and the run is 4. There for rise/run = 4/4 =1
The slope of the line is 1
Answer:
6.913 cubic-meters/second.
Step-by-step explanation:
Volume of pyramid is.
and
we essentially need to compute derivative at h = 3.
but firs we need to write s in terms of h only, to do that we use the fact that ration of side to height of a pyramid is always constant, which means.
solving for s and substituting in Volume function gives.
and taking derivative with respect to time gives.
but we have been given that piece of information so.
at h = 3 in above we have finally.
