Answers

Answer 1

The number `29` represents the median or the second quartile (Q2) age of the family reunion members.

The given data is of `20` people at a family reunion, ordered from youngest to oldest and the value of quartile 2 (Q2) is `29`.

The number `29` tells us about the people at the family reunion that:

Half of the family reunion members had an age of less than or equal to `29` years and half of the family reunion members had an age of more than or equal to `29` years.

In other words, the median age of the family reunion members is `29` years and out of the given ages of `20` people at a family reunion, half of the people are younger than `29` and half are older than `29`.

Therefore, the number `29` represents the median or the second quartile (Q2) age of the family reunion members.

Exercises 2.17 Interpolate a cubic spline between the three
points (0, 1), (2, 2) and (4, 0).

Answers

To interpolate a cubic spline between the points (0, 1), (2, 2), and (4, 0), we can use the concept of spline interpolation. A cubic spline is a piecewise-defined function consisting of cubic polynomials, which smoothly connects the given points.

In order to construct a cubic spline, we need to determine the coefficients of the cubic polynomials for each interval between the given points. The spline should satisfy three conditions: it must pass through each of the given points, it should have continuous first and second derivatives at the interior points, and it should have zero second derivatives at the endpoints to ensure a smooth connection.

We start by dividing the interval into three subintervals: [0, 2], [2, 4]. For each subinterval, we construct a cubic polynomial that satisfies the interpolation conditions. By imposing the continuity and smoothness conditions at the interior point (2, 2), we can obtain a system of equations. Solving this system gives us the coefficients of the cubic polynomials.

Once we have the coefficients, we can express the cubic spline as a piecewise function. The resulting cubic spline will smoothly connect the given points (0, 1), (2, 2), and (4, 0) and provide an interpolation function between them. This interpolation technique ensures a smooth and continuous curve, which can be useful for approximating values between the given data points.

True

False

Answers

Interest earned in the first year was $75. If the total interest for the next 10 years is $750, then the investment must be receiving simple interest. False.

If the total interest for the next 10 years is $750, it indicates that the investment is receiving compound interest, not simple interest. In compound interest, the interest earned in each period is added to the principal, resulting in an increasing base for calculating subsequent interest. Simple interest, on the other hand, is calculated solely based on the initial principal amount and does not incorporate any interest earned over time.

Step-by-step explanation:

Step 1

We have to rearrange the given days set from least to highest

35, 40, 45, 55, 60

(a) the range

Range = The highest number - The least number

= 60 - 35

= 25

(b) the standard deviation of the data set

35, 40, 45, 55, 60.

We find the Mean

Mean = Sum of values/Number of values

We can find the standard deviation now.

The formula =

√(x - Mean)²/n

= √(35 - 47)²+ (40 + 47)² + (45 - 47)² + (55 - 47)² + (60 - 47)²/5

Answers

The chi-square goodness-of-fit test requires that all anticipated counts be at least five and observations be drawn from random sample in order to be valid. The correct statements are I and III only. Correct option is C.

I. The chi-square goodness-of-fit test requires that all anticipated counts be at least five and that observations be drawn from a random sample in order to be valid. This statement is correct. The chi-square goodness-of-fit test is based on the chi-square distribution, which approximates the sampling distribution of the test statistic.

To ensure the validity of the test, it is generally recommended that all expected counts in the cells of the contingency table have a minimum expected count of five. This guideline helps to ensure that the chi-square test statistic follows the chi-square distribution, which is approximately valid under this condition.

II. The chi-square goodness-of-fit test uses 1 − n degrees of freedom. This statement is incorrect. The number of categories being assessed determines the degrees of freedom for the chi-square goodness-of-fit test. It is equal to the total categories less one. So, if there are n categories, the degrees of freedom for the test would be n - 1, not 1 - n.

III. A condition for using the chi-square goodness-of-fit test is that the observations are based on a random sample. This statement is correct. The chi-square goodness-of-fit test assumes that the observations are obtained from a random sample or represent a random selection from a population.

This assumption is important to ensure that the test results are generalizable to the population from which the sample is drawn. If the observations are not based on a random sample, the test results may not be valid or may be biased. Therefore, random sampling is a condition for using the chi-square goodness-of-fit test.

A coach buys a uniform and a basketball for each of the 20 players on the team. Each
basketball costs $10.40. The coach spends a total of $620 for uniforms and basketballs
What was the cost of a single uniform?

Answers

Answer:

$20.60

Step-by-step explanation:

You find how much it costs for the total amount of basketballs (10.40×20=208), then you subtract that number from the total cost of everything to get the cost of all the uniforms (620-208=412), then you divide the total costs for all uniforms by 20 to find the cost for a single uniform (412÷20=20.6).

the top of a swimming pool is at ground level. if the pool is 2.50 m deep, how far below ground level does the bottom of the pool appear to be located for the following conditions?

Answers

Given a swimming pool that is 2.50 m deep, we need to determine how far below ground level the bottom of the pool appears to be located.

The apparent depth of an object submerged in a medium, such as water, can be calculated using the concept of refraction. Refraction occurs when light travels from one medium to another, and its speed changes. According to Snell's law, the apparent depth (d') of an object in a medium is related to its actual depth (d) and the refractive index (n) of the medium.

The formula for calculating the apparent depth is:

d' = d / n.

In this case, the actual depth of the pool is 2.50 m, and the pool is filled with water, which has a refractive index of approximately 1.33.

Substituting the values into the formula, we have:

d' = 2.50 m / 1.33 ≈ 1.88 m.

Therefore, the bottom of the pool appears to be located approximately 1.88 meters below ground level. This means that when observing the pool from above, it would appear as if the bottom of the pool is situated 1.88 meters below the surface of the ground.

Use the Extended Euclidean Algorithm to show that the inverse of 177 in mod 901 is 56 by hand calculations ?

Answers

The inverse of 177 in mod 901 is indeed 56, as determined through the Extended Euclidean Algorithm by hand calculations.

Given that the inverse of 177 in mod 901 is 56.

To find the inverse of 177 modulo 901 using the Extended Euclidean Algorithm, perform the calculations step by step.

Step 1: Initialize the algorithm with the given values:

a = 901 (modulus)

b = 177 (number for which to find the inverse)

Introduce two variables:

[tex]x_0 = 1, y_0 = 0[/tex]

[tex]x_1 = 0, y_1 = 1[/tex]

Step 2: Perform the iterations of the Extended Euclidean Algorithm:

While b is not zero, repeat the following steps:

Calculate the quotient and remainder of a divided by b:

q = a / b

r = a % b (modulus operator)

Update the values of a and b:

[tex]a = b[/tex]

[tex]b = r[/tex]

Update the values of x and y:

[tex]x = x_0 - q * x_1[/tex]

[tex]y = y_0 - q * y_1[/tex]

Update the values of [tex]x_0, y_0, x_1, y_1[/tex]:

[tex]x_0 = x_1[/tex]

[tex]y_0 = y_1[/tex]

[tex]x_1 = x[/tex]

[tex]y_1 = y[/tex]

Step 3: Once the loop ends and b becomes zero, and obtain the      [tex]gcd(a, b) = gcd(901, 177) = 1[/tex], indicating that 177 has an inverse modulo 901.

Step 4: The inverse of 177 modulo 901 is given by [tex]y_0[/tex], which is 56.

Therefore, the inverse of 177 in mod 901 is indeed 56, as determined through the Extended Euclidean Algorithm by hand calculations.

90 + 17 = 107

180 - 107 = 73

So, the other angle is 73 degrees. If this is wrong I am so sorry. Hope this helps you, let me know if it is right!

Answer:

73°

Step-by-step explanation:

A right triangle has one right angle and two acute angles.

A right angle is 90° and the question says that one of the angle are 17°.

We need to add both angles together which = 107°.

A triangle internal total angles will always add up to 180°.

So we need to do 180° - 107° to find the missing angle which = 73°.

Also, the question said that the missing angles was acute and 73° is acute.
