Answer:
Population = All Sandhill cranes bred and hatched in Alaska that migrate south
Sample = The 50 crane samples which are tagged yearly.
Step-by-step explanation:
The population refers to all members or subjects which belongs to a defined study. Each and every subject which meets the requirement of a study makes up the population.
The sample however, is a subset of the population, the sample is a smaller group of subject which is selected from the population randomly to for a representative sample of the population. Here, it is the 50 sampled sandhill cranes bed per year.
The given curve crosses the x-axis whenever x is a multiple of π, and it lies above the x-axis between consecutive even and odd multiples of π. So the regions with area S₀, S₁, S₂, ... are the sets
and so on, with
for natural number k.
The areas themselves are then given by the integral
Integrate by parts twice. Take
so that
then
so that
Overall, we find
or
Using the antiderivative and the fundamental theorem of calculus, we compute the k-th area to be
Since , the sum we want is a convergent geometric sum. As n goes to ∞, we have
Step-by-step explanation:
Question 8)
2,8,14
d=a2-a1
d=8-2=6
a77= 2+ (76)*6
a77= 2+456=458
a77= 458
Question 9)
-12,-17,-22
d= -17+12= -5
a82= -12+ (81)*(-5)= -12-405= 417
a82= 417
Question 10)
9,13,17
d= 13-9= 4
a49= 9+ (48)*4= 201
a49= 201
Answer: 105
Step-by-step explanation:
Corresponding sides of similar triangles are proportional, so
The median is the middle of a list of numbers from least to greatest.
I will set up the numbers from least to greatest for you.
5, 6, 6, 8, 9.
To determine the median, cross out the smallest number with the largest number until you can no longer do so.
5, 6, 6, 8, 9.
6, 6, 8.
6.
Your median is 6.
I hope this helps!
