The Data Set Shows The Number Of Actors Used In Several School Plays Across Des Moines. 1. Which Is Greater

Answers

Answer 1

The comparison of the mean and median of the data set of the dot plot in the first part and the variability and outlier of the dataset in the box and whiskers plot in the second part are;

First part;

1. The median is greater than the mean.

2. Both the mean and median will increase

Second part;

1. School 1 has greater variability

2. The maximum value of school 1 is not an outlier

3. The new athlete needs to spend 21 hours or more

How can the dot and box and whiskers plots be analyzed?

First part;

1. The value in the dot plot are;

10, 11, 12, 12, 13, 13, 13, 14, 14, 14, 14, 14, 15, 15, 15, 15, 15, 15, 16, 16, 16, 16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 19

The number of data points = 36

The mean = The sum of the above data divided by 36

Using an online calculator of data sets, we have;

The mean = 15.194The median = 15.5

Therefore;

The median is greater than the mean.

2. The addition of 60 to the dataset will increase the number of data points from 36 to 37, thereby changing the median, which is the middle value to the 19th number, which is 16, while the mean value will also increase to 16.405, therefore;

The mean and median will both increase

Second part;

1. A measure of variability of a box plot is the range, which is the difference between the largest and smallest values.

The range of school 1 is; 16 - 1 = 15

The range of school 2 is; 14 - 1 = 13

Therefore;

School 1 has greater variability.

2. The maximum value of school 1 is 16

The inter quartile range of school 1 is; IQR = 10 - 4 = 6

An outlier = Q3 + 1.5 × IQR

The third quartile, Q3, for school 1 = 10

Which gives;

An outlier ≥ 10 + 1.5 × 6 = 19

The maximum value for school 1 = 16 < 19, is not an outlier.

3. Q3 for school 2 = 12

IQR for school 2 = 12 - 6 = 6

Which gives;

Outlier for school 2 ≥ 12 + 1.5 × 6 = 21

To be considered an upper end outlier in school 2, the student needs to spend 21 hours or more in the weight room.

The length of the missing side for the triangle is equal to 5.96 to the nearest tenth hundredth using the sine rule.

What is the sine rule

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

First, we find the angle opposite the side length 5 as follows;

180 - (34 + 118) = 28 {sum of interior angles of a triangle}

Using the sine rule;

5/sin28° = ?/sin34°

? = (5 × sin34°)/sin28° {cross multiplication}

? = 5.9556

Therefore, the length of the missing side for the triangle is equal to 5.96 to the nearest tenth hundredth using the sine rule.

Consider the random walk with drift model


xt = δ + xt-1 + wt for t = 1,2,3,… with x0 = 0 and wt is white noise with mean zero and variance σw2.


a. Show the model can be written as xt = δt + ∑1twk (Hint: Use induction.)

v. Find the mean function and autocovariance function of xt.

c. Determine if xt is stationary.

Answers

a. To show that the model can be written as xt = δt + ∑1twk, we can use induction.

For t = 1:

x1 = δ + x0 + w1

= δ + 0 + w1

= δ + w1

So the base case holds.

Assume that the model holds for t = k, i.e., xk = δk + ∑1k wk.

For t = k+1:

xk+1 = δ + xk + wk+1

= δ + (δk + ∑1k wk) + wk+1

= δk+1 + ∑1k+1 wk

Therefore, by induction, the model can be written as xt = δt + ∑1twk.

v. To find the mean function of xt, we can take the expected value of both sides of the model equation:

E[xt] = E[δt + ∑1twk]

= E[δt] + E[∑1twk]

= δt + ∑1tE[wk]

= δt

So, the mean function of xt is given by μt = δt.

To find the autocovariance function of xt, we need to calculate Cov(xt, xs) for s ≠ t.

For s < t:

Cov(xt, xs) = Cov(δt + ∑1twk, δs + ∑1swk)

= Cov(δt, δs) + Cov(δt, ∑1swk) + Cov(∑1twk, δs) + Cov(∑1twk, ∑1swk)

= 0 + 0 + 0 + Cov(∑1twk, ∑1swk)

= Cov(∑1twk, ∑1swk)

= Cov(wt + ∑1t-1wk, ws + ∑1s-1wk)

= Cov(wt, ws) + Cov(wt, ∑1s-1wk) + Cov(∑1t-1wk, ws) + Cov(∑1t-1wk, ∑1s-1wk)

= 0 + 0 + 0 + Cov(∑1t-1wk, ∑1s-1wk)

Since wt and wk are white noise with mean zero and variance σw^2, their covariance is zero unless t = s. Therefore, we have:

Cov(xt, xs) = 0 for s < t

For s > t, the covariance remains zero as well, since we can use the same logic as above.

For s = t, we have:

Cov(xt, xs) = Cov(δt + ∑1twk, δt + ∑1twk)

= Cov(δt, δt) + Cov(δt, ∑1twk) + Cov(∑1twk, δt) + Cov(∑1twk, ∑1twk)

= Var(δt) + Cov(∑1twk, ∑1twk)

= Var(δt) + Var(∑1twk) + 2Cov(∑1twk, ∑1twk)

= Var(δt) + Var(∑1twk) + 2∑1t-1Cov(wk, wk)

= Var(δt) + Var(∑1twk) + 2∑1t-1σw^2

Since δ is a constant and wk is a white noise process, Var(∑1twk) = ∑1tVar(wk) = tσw^2.

Therefore, we have:

Cov(xt, xs) = Var(δt) + tσw^2 + 2∑1t-1σw^2

= Var(δt) + tσw^2 + 2σw^2(t-1)

= Var(δt) + 3tσw^2 - 2σw^2

Finally, we can conclude that the mean function of xt is μt = δt, and the autocovariance function of xt is Cov(xt, xs) = Var(δt) + 3tσw^2 - 2σw^2.

c. To determine if xt is stationary, we need to check if the mean function and autocovariance function are independent of time (t).

In this case, the mean function is μt = δt, which is dependent on time. Therefore, xt is not stationary.

Similarly, the autocovariance function Cov(xt, xs) = Var(δt) + 3tσw^2 - 2σw^2 depends on both t and s, so xt is not stationary.

Answers

To determine the probabilities, we need to consider the number of favorable outcomes for each situation divided by the total number of possible outcomes.

1.Probability: 228/700 = 0.3257 ≈ 32.57% ≈ 32.6% (rounded to one decimal place)

2. Probability: 200/3500 = 0.0571 ≈ 5.71% ≈ 5.7%

3. Probability: 504/2100 = 0.24 ≈ 24% (exact fraction)

4.Probability: 180/1400 = 0.1286 ≈ 12.86% ≈ 12.9% (rounded to one decimal place)

1. Salmon chooses a composite number, a cool color (G, B, I, or V), and an A:

a) Composite numbers between 1 and 100: There are 57 composite numbers in this range.

b) Cool colors (G, B, I, or V): There are 4 cool colors.

c) The letter A: There is 1 A in "INDIANA."

Total favorable outcomes: 57 (composite numbers) * 4 (cool colors) * 1 (A) = 228

Total possible outcomes: 100 (possible numbers) * 7 (possible colors) * 1 (possible letter) = 700

Probability: 228/700 = 0.3257 ≈ 32.57% ≈ 32.6% (rounded to one decimal place)

2. Federico chooses a prime number, a color starting with a vowel (E or I), and a consonant:

a) Prime numbers between 1 and 100: There are 25 prime numbers in this range.

b) Colors starting with a vowel (E or I): There are 2 colors starting with a vowel.

c) Consonants in "INDIANA": There are 4 consonants.

Total favorable outcomes: 25 (prime numbers) * 2 (vowel colors) * 4 (consonants) = 200

Total possible outcomes: 100 (possible numbers) * 7 (possible colors) * 5 (possible letters) = 3500

Probability: 200/3500 = 0.0571 ≈ 5.71% ≈ 5.7% (rounded to one decimal place)

3. Either chooses a number divisible by 7 or 8, any color, and a vowel:

a) Numbers divisible by 7 or 8: There are 24 numbers divisible by 7 or 8 in the range of 1 to 100.

b) Any color: There are 7 possible colors.

c) Vowels in "INDIANA": There are 3 vowels.

Total favorable outcomes: 24 (divisible numbers) * 7 (possible colors) * 3 (vowels) = 504

Total possible outcomes: 100 (possible numbers) * 7 (possible colors) * 3 (possible letters) = 2100

Probability: 504/2100 = 0.24 ≈ 24% (exact fraction)

4. Either chooses a number divisible by 5 or 4, blue or green, and L or N:

a) Numbers divisible by 5 or 4: There are 45 numbers divisible by 5 or 4 in the range of 1 to 100.

b) Blue or green colors: There are 2 possible colors (blue or green).

c) L or N in "INDIANA": There are 2 letters (L or N).

Total favorable outcomes: 45 (divisible numbers) * 2 (possible colors) * 2 (letters) = 180

Total possible outcomes: 100 (possible numbers) * 7 (possible colors) * 2 (possible letters) = 1400

Probability: 180/1400 = 0.1286 ≈ 12.86% ≈ 12.9% (rounded to one decimal place)

In ABC, BAC=96•8°,AC= 12•4cm and BC=15•6cm. Find
i) ABC,
ii) BCA,
iii) the length of AB,

Answers

In the triangle ABC, i) ABC = 52.12° ii) BCA = 31.08° and iii) AB = 8.11cm.

Based on the provided information, ∠ BAC = 96.8°; AC = 12.4cm, and BC = 15.6cm

i) According to the law of sine,

Sin ∠A/a = Sin ∠B/b = Sin ∠C/c where a is the length opposite to ∠A, and so forth.

Hence, based on the information, ∠ABC = ∠B

Sin ∠B/AC = Sin ∠A/BC

Sin ∠B/12.4 = Sin 96.8/15.5

Sin ∠B = (Sin 96.8/15.5)*12.4

∠B = Sin^-1((Sin 96.8/15.5)*12.4)

∠B = 52.12°

ii) As the sum of interior angles of a triangle is 180°. ∠As BCA = ∠C

∠A + ∠B + ∠C = 180

96.8 + 52.12 + ∠C = 180

∠C = 31.08

iii) According to the law of cosine,

c^2 = a^2 + b^2 – 2ab cos C where C is the angle opposite to c.

BC^2 = AB^2 + AC^2 – 2(AB)(AC)cos98.6

15.6^2 = AB^2 + 12.4^2 – 2(AB)(12.4)cos98.6

Choosing a point O of the line (the origin), a unit of length, and an orientation for the line are all steps in choosing a Cartesian coordinate system for a one-dimensional space, or for a straight line. The line "is oriented" (or "points") from the negative half towards the positive half when an orientation determines which of the two half-lines given by O is the positive half and which is the negative half. Then, depending on which half-line contains P, the distance between each point P on the line and O can be specified.

a) O = (0, 0) a = (2, -1)∈R²

The unit tangent vector T(t), normal vector N(t), and curvature κ(t) for the given plane curve are T(t) = (5/√(1+t^2))i + (-1/√(1+t^2))j, N(t) = (-1/√(1+t^2))i + (-5/√(1+t^2))j, and κ(t) = 5/√(1+t^2).

To find the unit tangent vector T(t), we differentiate the position vector r(t) = (5t+1)i + (5-t^5)j with respect to t, and divide the result by its magnitude to obtain the unit vector.

To find the normal vector N(t), we differentiate the unit tangent vector T(t) with respect to t, and again divide the result by its magnitude to obtain the unit vector.

To find the curvature κ(t), we use the formula κ(t) = |dT/dt|, which is the magnitude of the derivative of the unit tangent vector with respect to t.

Performing the necessary calculations, we obtain T(t) = (5/√(1+t^2))i + (-1/√(1+t^2))j, N(t) = (-1/√(1+t^2))i + (-5/√(1+t^2))j, and κ(t) = 5/√(1+t^2).

Therefore, the unit tangent vector T(t) is (5/√(1+t^2))i + (-1/√(1+t^2))j, the normal vector N(t) is (-1/√(1+t^2))i + (-5/√(1+t^2))j, and the curvature κ(t) is 5/√(1+t^2).

Answers

Answer:

19.87301587

Step-by-step explanation:

Answer:

Step-by-step explanation:

Ok, so you would use PEMDAS, which is the correct order in which you would need to solve an equation. The idea is that the operations that come first would have to be solved first.

If you don't know it, PEMDAS is:

Parentheses

Exponents

Multiplication/division

Addition/subtraction

In this case, you would need to solve the parentheses. (7x9) is 63.

It would be rewritten as 4x5-8/63

There are no exponents, so you can skip the next operation.

Then you would do multiplication next, which would be 4x5 = 20

The equation would be rewritten as 20-8/63

-0.126984127 is -8/63

Lastly, 19.8730159 is the result of 20-0.126984127

2. Tell whether each function is linear. If so, graph
the function.
2y = -4x

Answers

The function 2y = -4x is linear and the graph is given below.

What is Linear Function?

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables and the exponent of the variable is 1.

Here the given function is 2y = -4x.

The function is linear since the exponent of the two variables x and y are 1.

This can be written as,

y = -4x / 2

y = -2x

This is a proportional function with slope -2.

Graph will be a decreasing function.

The points on the graph includes (-2, 4), (-1, 2), (0, 0), (1, -2) and (2, -4).

Hence the graph of the function is given below.

prove the identity. sinh(2x) = 2 sinh(x) cosh(x)

Answers

To prove the identity sinh(2x) = 2 sinh(x) cosh(x), we can use the definitions of sinh(x) and cosh(x) and apply trigonometric identities for exponential functions.

We start with the left-hand side of the identity, sinh(2x). Using the definition of the hyperbolic sine function, sinh(x) = (e^x - e^(-x))/2, we can substitute 2x for x in this expression, giving us sinh(2x) = (e^(2x) - e^(-2x))/2.

Next, we focus on the right-hand side of the identity, 2 sinh(x) cosh(x). Again using the definitions of sinh(x) and cosh(x), we have 2 sinh(x) cosh(x) = 2((e^x - e^(-x))/2)((e^x + e^(-x))/2).

Expanding this expression, we get 2 sinh(x) cosh(x) = (e^x - e^(-x))(e^x + e^(-x))/2.

By simplifying the right-hand side, we have (e^x * e^x - e^x * e^(-x) - e^(-x) * e^x + e^(-x) * e^(-x))/2.

This simplifies further to (e^(2x) - 1 + e^(-2x))/2, which is equal to the expression we derived for the left-hand side.

Hence, we have proved the identity sinh(2x) = 2 sinh(x) cosh(x) by showing that the left-hand side is equal to the right-hand side through the manipulation of the exponential functions.
