Step-by-step explanation:
The following is based on information from The Wolf in the Southwest: The making of an Endangered Species by David E. Brown ( University of Arizona Press). Before 1918the proportion of female wolves in the general population of all southwestern wolves wasabout 50%. However, after 1918, southwestern cattle ranchers began a widespread effort to destroy wolves. In a recent sample of 34 wolves, there were only 10 females. One theoryis that male wolves tend to return sooner than females to their old territories where their predecessors were exterminated. Do these data indicate that the populationproportion of female wolvesis now less than 50% in the region?
This question is incomplete, the complete question is;
The following is based on information from The Wolf in the Southwest: The making of an Endangered Species by David E. Brown ( University of Arizona Press). Before 1918the proportion of female wolves in the general population of all southwestern wolves was about 50%. However, after 1918, southwestern cattle ranchers began a widespread effort to destroy wolves. In a recent sample of 34 wolves, there were only 10 females. One theory is that male wolves tend to return sooner than females to their old territories where their predecessors were exterminated. Do these data indicate that the population proportion of female wolves is now less than 50% in the region? Use ∝ = 0.01
Answer:
Since p-value (0.0082) < ∝ ( 0.01 ), we reject null hypothesis.
Therefore, at 0.01 significance level, we have sufficient evidence that the population proportion of female wolves is now less than ( 0.5 ) 50% in the region.
Step-by-step explanation:
Given the data in the question;
Hypothesis;
H₀ : p ≥ 0.5 { 50% }
H₁ : p < 0.5
This is a lower tailed test { H₁ : p < 0.5 }
sample size n = 34
number of female wolves x = 10
sample proportion p" = x / n = 10 / 34 = 0.2941176
claimed proportion P = 0.5
significance level ∝ = 0.01
we determine the standard deviation of p"
σ[tex]_{p"[/tex] = √[ (p(1 - p)) / n ] = √[ (0.5(1 - 0.5)) / 34 ]
= √[ (0.5 ×0.5) / 34 ]
σ[tex]_{p"[/tex] = 0.08575
Test statistics
[tex]z_{observed[/tex] = (p" - 0.5) / σ[tex]_{p"[/tex]
[tex]z_{observed[/tex] = (0.2941176 - 0.5) / 0.08575
[tex]z_{observed[/tex] = -2.40
so
Test statistic : -2.40
Since its a lower tailed test;
P-value = P( Z < [tex]z_{observed[/tex] ) = P( Z < -2.40 ) = 0.0082
Rejection criteria: Reject H₀ if p-value < ∝
Decision:
Since p-value (0.0082) < ∝ ( 0.01 ), we reject null hypothesis.
Therefore, at 0.01 significance level, we have sufficient evidence that the population proportion of of female wolves is now less than ( 0.5 ) 50% in the region.

Mhanifa please help me with this
Answer:
NoStep-by-step explanation:
If we assume there is such a proportion, then we have the proportion:
m(x) = kx, where m is amount the person eats, k is coefficient of proportion, x is age of the personFor 5 year old we have:
m(5) = 5kFor 20 year old:
m(20) = 20kFor 60 year old:
m(60) = 60kIn reality this proportion doesn't make sense as 60 year old normally eats less than 20 year old.

Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
f(x) = - 0.6x² + 4.2x + 240 ← factor out - 0.6 from the first 2 terms
= - 0.6(x² - 7x) + 240
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² - 7x
f(x) = - 0.6(x² + 2(- 3.5)x + 12.25 - 12.25 ) + 240
= - 0.6 (x - 3.5)² + 7.35 + 240
= - 0.6(x - 3.5)² + 247.35
with vertex = (3.5, 247.35 )
The maximum value is the y- coordinate of the vertex
Then
f(x) = - 0.6(x - 3.5)² + 247.35 has a maximum value of 247.35
ITS TIMED... please help. f(x) = -3x - 4

Find the circumference of a circle with radius, r = 16.5m.
Give your answer in terms of pi.
Answer:
33π is the answer in terms of pi.
Step-by-step explanation:
Circumference of circle formula is C=πd.
Plug in the given values. We put 33 into d, because d represents diameter, and diameter is twice the radius(16.5), so we multiply 16.5 by 2. So far we have C=(π)(33).
C=(π)(33)=33π

Answer:
the perimeter is 11cm and the area is 7cm^2
Step-by-step explanation:
NP =PS, meaning they have the same length. so the perimeter is 3.5 + 4 + another 3.5.
For the area imagine you cut the triangle in half. from P to the middle of NS. Put the 2 triangle halves together to form a rectangle. (PS is now touching NP). This would be a 2x 3.5 rectangle. 2x 3.5 is 7, meaning both this imagined rectangle and the triangle have an area of 7cm^2.

Question 5 :)) What is the measure of the missing angle?
The first term of a sequence is 4 and the common
ratio is -2. What is the formula for the sequence
based on term number
Qy --2-(4)-1
ay -4.(-2)2-1
an = (4.-2)^2=1
an - 4.(-2)
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Geometric Progression.
So, we know that,
GP = a.r^(n-1)
here, a = 4 and r = -2
so we get as,
an = 4.(-2)^n-1
Option B.) is correct

when you are given a zero of a function and told that it has a multiplicity of 3, what does that mean?
Answer:
the zero of a function is what value you can plug in and get 0 as the answer.
having a multiplicity of 3 means that the zero is there 3 times so if your zero is 2 with multiplicity 3 then (x-2)^3 is what it looks like
Step-by-step explanation:
Given {(1, 2), (3, 5), (-2, 2), (3,6)}, choose the pair of coordinates that clarify why this
relation is not a function.
Given:
The relation is:
[tex]\{(1, 2), (3, 5), (-2, 2), (3,6)\}[/tex]
To find:
The pair of coordinates that clarify why this relation is not a function.
Solution:
A relation is called a function if there exist unique y-value for each x-value. In other words, if a relation has two outputs for a single input, then the relation is not a function.
The given relation is:
[tex]\{(1, 2), (3, 5), (-2, 2), (3,6)\}[/tex]
This relation has two y-values 5 and 6 for a single x-value 3. Since the y-value is not unique all all values of x, therefore the relation is not a function.
Hence, the pairs of coordinates (3,5) and (3,6) clarify that the given relation is not a function.
