2x3x11
Step-by-step explanation:
Answer:
600 baboons
Step-by-step explanation:
Half the number of marked baboons showed up in the sample, so we expect the sample size to be about half of the total population. 300 is half of 600.
___
Many assumptions are involved in such an experiment and analysis. Not the least of which are the assumptions that the marked baboons end up evenly distributed through the population, and that the sample is a fair sample of the entire population.
Answer:
v=2
Step-by-step explanation:
9v-3v=12
6v=12
v=2
<span>Standard Form of an Equation of an Hyperbola opening up and down is:
(y-k)^2 / b^2 - (x-h)^2 / a^2 = 1
</span><span>where Pt(h,k) is a center with vertices 'b' units up and down from center.
</span><span>vertices: vertices: (0,+-2) b = 2 AND Center is (0,-0)
(y)^2/4-(x)^2/a^2=1
</span><span>foci: (0,+-7)
a^2 = 24
square root of 4 + a^2 = 5.29
4 + 5.29 = 9.29
y^2 / 4 - x^2 / 24 = 1</span>
