The present value (PV) is $3000.45 when it is rounded to two decimal places.

We can use the following formula for the present value of an annuity:

PV = PMT * [(1 - (1 + i)^(-n)) / i]

Here, n = 20, i = 0.027, and PMT = $207. Now, plug in the values:

PV = 207 * [(1 - (1 + 0.027)^(-20)) / 0.027]

First, calculate the values inside the parentheses:

(1 + 0.027)^(-20) = 0.60829 (rounded to 5 decimal places)

Next, subtract this value from 1:

1 - 0.60829 = 0.39171 (rounded to 5 decimal places)

Now, divide the result by the interest rate:

0.39171 / 0.027 = 14.50704 (rounded to 5 decimal places)

Finally, multiply this value by the payment amount:

207 * 14.50704 = 3000.45

So, the present value (PV) is $3000.45 when rounded to two decimal places.

The letter used to represent Pearson's product-moment correlation coefficient is "r".

This coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no linear correlation.

To calculate Pearson's correlation coefficient, we first standardize the variables by subtracting their means and dividing by their standard deviations. Then, we calculate the product of the standardized values for each pair of corresponding data points. The sum of these products is divided by the product of the standard deviations of the two variables. The resulting value is the correlation coefficient "r".

1. See attachment for the labelled tree diagram

2. The outcomes are {HR, HY, HB, TR, TY, TB}

3. The sample space is {HR, HY, HB, TR, TY, TB}

4. The outcomes in the event "Toss a tails, spin yellow" is 1

5. The probability of tossing tails and spinning yellow is 1/6

Given that

Coin = Head or Tail

Spinner = Red, Yellow, Blue

Next, we complete the columns using the above

See attachment

Using the following key

From the completed tree diagram, the outcomes are

Outcomes = {HR, HY, HB, TR, TY, TB}

This means that the total number of outcomes is 6

And each outcome has a probability of 1/6

This is the same as the outcomes written inside the rectangles

So, we have

Sample space = {HR, HY, HB, TR, TY, TB}

Here, we have

"Toss a tails, spin yellow"

This is represented as TY

So, the outcomes in the event "Toss a tails, spin yellow" is 1

In (b), we have

Each outcome has a probability of 1/6

This means that the probability of tossing tails and spinning yellow is 1/6

By using  piecewise functions the values of  [tex]\lim_{\theta \to \pi^+} h(\theta)[/tex] is 1 and  [tex]\lim_{\theta \to \pi/2^-} h(\theta)[/tex] is -1

The given functions are h(θ)=cos2θ, θ<π/2

h(θ)=tanθ/2,   π/2<θ≤π

h(θ)=sinθ/2, θ ≥π

Now let us find the value of [tex]\lim_{\theta \to \pi^+} h(\theta)[/tex]

[tex]\lim_{\theta \to \pi^+} \frac{ sin(\theta)}{2}[/tex]

This is a right hand limit which we take the values greater than π.

Apply the limit theta as pi.

sinπ/2

We know that sin90 degrees is 1.

[tex]\lim_{\theta \to \pi^+} h(\theta)[/tex]=1

Now [tex]\lim_{\theta \to \pi/2^-} h(\theta)[/tex]

This is a left hand limit which we take the values lesser than π/2.

[tex]\lim_{\theta \to \pi/2^-} cos(2\theta)[/tex]

Now apply the limit theta as π/2.

cos2(π)/2

[tex]\lim_{\theta \to \pi/2^-} h(\theta)[/tex] = -1
