Part (a)
Refer to the diagram below to see the two triangles separated.
================================================
Part (b)
If the 3 meter portion is perpendicular to the horizontal portion, then the triangles are similar. We can prove this using the AA similarity theorem. One pair of angles would be the shared overlapping 25 degree angles. The other pair of congruent angles would be the two 90 degree angles. We only need two pairs of congruent angles to use AA. You could use three pairs (and the aptly named AAA theorem) but that's overkill in my book.
================================================
Part (c)
There are a few ways to approach this, but one way is shown below
y/3 = (8.4+6.6)/(6.6)
y/3 = 15/(6.6)

6.6y = 45
y = 45/(6.6)
y = 6.81818 approximately
When rounding to one decimal place, we get y = 6.8

if the ball drawn from bag a is black, find the probability that a white ball was transferred from bag b into bag a.
The probability that a white ball was transferred from bag b into bag a given that a black ball was drawn from bag a is approximately 0.5760.
Let us denote the events as follows,
A represents the ball drawn from bag a is black
B represents the ball transferred from bag b to bag a is white
Probability of event B given that event A has occurred is P(B|A).
Using Bayes' theorem ,
P(B|A) = P(A|B) × P(B) / P(A) __(1)
P(A|B) = Probability of drawing a black ball from bag a given that a white ball was transferred from bag b to bag a.
P(A|B)
= (3/5)× (5/9) + (4/9)× (4/9)
= 43/81
P(B) = Probability of transferring a white ball from bag b to bag a
= 5/9
P(A) = Probability of drawing a black ball from bag a.
Using the law of total probability,
P(A) = P(A|B) ×P(B) + P(A|B') × P(B')
Here, B' represents the event that a black ball was transferred from bag b to bag a.
P(B') = 4/9
P(A|B')
= (3/5) × (4/9) + (2/5) × (5/9)
= 22/45
Now,
P(A)
= (43/81) ×(5/9) + (22/45)× (4/9)
= 0.512
Substitute all the values into Bayes' theorem,
P(B|A)
= (43/81) × (5/9) / (0.512)
≈ 0.5760
Therefore, the required probability of transferring a ball from one bag to another is approximately 0.5760.

what are the equivalence classes of equivalance relation {(1, 1), (1, 4), (2, 2), (2, 5), (3, 3), (4,1), (4, 4), (5, 2), (5, 5)}?
The equivalence classes of the given equivalence relation are: {1, 4}, {2, 5}, and {3}. To determine the equivalence classes of the equivalence relation given by {(1, 1), (1, 4), (2, 2), (2, 5), (3, 3), (4,1), (4, 4), (5, 2), (5, 5)}, we need to identify all the pairs of elements that are related to each other.
Two elements are related if there is a pair (a, b) in the relation such that a is related to b. In this case, we can see that:
- 1 is related to 1 and 4
- 2 is related to 2 and 5
- 3 is related to 3
- 4 is related to 1 and 4
- 5 is related to 2 and 5
We can use these relationships to group the elements into equivalence classes. An equivalence class is a set of elements that are related to each other. In this case, we have the following equivalence classes:
- {[1, 4]}: This equivalence class contains the elements 1 and 4, which are related to each other.
- {[2, 5]}: This equivalence class contains the elements 2 and 5, which are related to each other.
- {[3]}: This equivalence class contains the element 3, which is related to itself.
- {[1, 4], [2, 5]}: This equivalence class contains the elements 1, 4, 2, and 5, which are all related to each other.
- {[1, 4], [2, 5], [3]}: This equivalence class contains all the elements, since they are all related to each other.
Each equivalence class contains elements that are related to each other, and no element in one equivalence class is related to any element in another equivalence class. These equivalence classes form a partition of the set of elements, since every element is contained in exactly one equivalence class.

By comparison, the average compensation for workers was $54,700 in 2009 and $55,800 in 2016. Assume that both values are growing exponentially. Find the growth rate r for both salaries. State your answers as percentages rounded to the nearest tenth of a percent.For CEOs: r= %For workers: r = %
The exponential growth formula is given by
\(C=a(1+r)^t\)where C is the average compensation, a is the initial amount and t is the time (in years).
For the CEO's case, we have that
\(\begin{gathered} \text{for t=2009, C=10800000} \\ \text{for t=2016, C=12800000} \end{gathered}\)Then, we can find a and r with these values. By substituting the first values, we have
\(10800000=a(1+r)^{2009}\)By substituting the second values, we get
\(128000000=a(1+r)^{2016}\)By isolating a in both case, we have that
\(\begin{gathered} a=\frac{10800000}{(1+r)^{2009}} \\ \text{and} \\ a=\frac{12800000}{(1+r)^{2016}} \end{gathered}\)Then, we can state the following equation:
\(\frac{10800000}{(1+r)^{2009}}=\frac{12800000}{(1+r)^{2016}}\)or equivalently,
\(\begin{gathered} \frac{(1+r)^{2016}}{(1+r)^{2009}}=\frac{128000000}{108000000} \\ \frac{(1+r)^{2016}}{(1+r)^{2009}}=1.185185 \end{gathered}\)By applying natural logarithm in bot sides, we have
\(\begin{gathered} \ln (\frac{(1+r)^{2016}}{(1+r)^{2009}})=\ln 1.185185 \\ \ln (\frac{(1+r)^{2016}}{(1+r)^{2009}})=0.169899 \end{gathered}\)By the properties of logarithms:
\(\ln (\frac{A}{B})=\ln A-\ln B\)we obtain
\(\ln (1+r)^{2016}-\ln (1+r)^{2009}=0.169899\ldots.(a)\)By the property of logaritm:
\(\ln A^x=x\ln A\)The last result is equivalent to
\(\begin{gathered} 2016\ln (1+r)-2009\ln (1+r)=0.169899 \\ which\text{ gives} \\ 7\ln (1+r)=0.169899 \end{gathered}\)then, by moving the number 7 to the right hand side, this yields,
\(\begin{gathered} \ln (1+r)=\frac{0.169899}{7}\ldots(b) \\ \ln (1+r)=0.024271 \end{gathered}\)Now, by applying the exponential function in both sides, we have
\(\begin{gathered} 1+r=e^{0.024271} \\ 1+r=1.024568 \end{gathered}\)then, r is given by
\(\begin{gathered} r=1.024568-1 \\ r=0.0245 \end{gathered}\)Now, by converting this result into percent form. The answer for the CEO's case is
\(r=2.45\text{ \%}\)Now, for the workers case, we can do the same procedure and get an equation similar to equation (a). That is,
\(\begin{gathered} \ln (1+r)^{2016}-\ln (1+r)^{2009}=\ln (\frac{55800}{54700}) \\ \ln (1+r)^{2016}-\ln (1+r)^{2009}=\ln (1.020109) \\ \ln (1+r)^{2016}-\ln (1+r)^{2009}=0.0199 \end{gathered}\)and find somthing similar to equation (b)
\(\begin{gathered} \ln (1+r)=\frac{0.0199}{7}\ldots \\ \ln (1+r)=0.0028 \end{gathered}\)and finally,
\(\begin{gathered} 1+r=e^{0.0028} \\ 1+r=1.0028 \end{gathered}\)then, r will be
\(\begin{gathered} r=1.0028-1 \\ r=0.0028 \\ In\text{ percent form is} \\ r=\text{ 0.28 \%} \end{gathered}\)In summary,by rounding the answers to the nearest tenth percent, the answers are
\(\begin{gathered} \text{For CEO's:} \\ r=2.5\text{ \%} \\ \text{For workers:} \\ r=0.3\text{ \%} \end{gathered}\)3. as sample size decreases, what happens to the degrees of freedom? select all that apply. group df increases group df decreases error df increases error df decreases total df increases total df decreases
As sample size decreases, the degrees of freedom decrease.
This affects both the group and error degrees of freedom. Specifically:
The group degrees of freedom (df between) decrease as the number of groups decreases. This is because there are fewer groups to estimate the population means from, resulting in fewer degrees of freedom for group differences.
The error degrees of freedom (df within) decrease as the sample size within each group decreases. This is because there is less information available to estimate the variation within each group, resulting in fewer degrees of freedom for residual variation.
The total degrees of freedom (df total) also decrease as the number of observations decreases, since the total degrees of freedom is equal to the number of observations minus 1.

1. Use Horner's algorithm to find p(4), where p(z) = 3z^2 – 7z^4 – 5z^3+z^2 -- 8z +2. 2. (Continuation) For the polynomial of preceding problem, find its expansion in a Taylor series about the point z0 = 4. 3. (Continuation) For the polynomial of Problem 3.5.1 (above), start Newton's method at the point z0 = 4. What is z1?
Evaluating p(4) using Horner's algorithm:
1. To use Horner's algorithm, we write the polynomial in nested form as follows:
p(z) = ((3z - 7)z - 5)z^2 + (z - 8)z + 2
Now, we can evaluate p(4) by starting from the inside and working our way out:
p(4) = ((3(4) - 7)4 - 5)4^2 + (4 - 8)4 + 2
= (5)4^2 - 4 + 2
= 78
Therefore, p(4) = 78.
2. Finding the Taylor series expansion of p(z) about z0 = 4:
To find the Taylor series expansion of p(z) about z0 = 4, we need to compute the derivatives of p(z) at z0 = 4. First, we compute p'(z) = 6z^2 - 28z^3 - 10z^2 + 2z - 8, then p''(z) = 12z - 84z^2 - 20z + 2, p'''(z) = 12 - 168z - 20, and so on.
Using these derivatives, we can write the Taylor series expansion of p(z) about z0 = 4 as follows:
p(z) = p(4) + p'(4)(z - 4) + p''(4)(z - 4)^2/2! + p'''(4)(z - 4)^3/3! + ...
Substituting in the values we computed, we get:
p(z) = 78 + 10(z - 4) - 41(z - 4)^2/2! - 14(z - 4)^3/3! + ...
Therefore, the Taylor series expansion of p(z) about z0 = 4 is:
p(z) = 78 + 10(z - 4) - 20.5(z - 4)^2 - 2.333(z - 4)^3 + ...
3. Using Newton's method to find a root of p(z):
To use Newton's method to find a root of p(z), we start with an initial guess z0 = 4 and iterate the formula z1 = z0 - p(z0)/p'(z0) until we reach a desired level of accuracy.
4. We already computed p'(z) in part 2, so we can use the formula to compute z1 as follows:
z1 = z0 - p(z0)/p'(z0)
= 4 - (78 + 10(4) - 20.5(4 - 4)^2 - 2.333(4 - 4)^3)/[6(4)^2 - 28(4)^3 - 10(4)^2 + 2(4) - 8]
= 3.9167
We can continue to iterate using this formula to get better approximations for the root of p(z).
Horner's algorithm is a fast and efficient way to evaluate a polynomial at a particular point. It involves using the distributive property of multiplication to rewrite a polynomial in a nested form, then evaluating the polynomial from the inside out.
In this problem, we will use Horner's algorithm to evaluate p(4) for a given polynomial, find its Taylor series expansion about the point z0 = 4, and then use Newton's method to find an approximation for a root of the polynomial.
