The Methods used that summarize or organize characteristics of data is descriptive.

Methods used to summarize or organize characteristics of data are referred to as descriptive methods.

Descriptive methods are used to describe the basic features of a set of data, such as its central tendency (mean, median, mode) and dispersion (range, variance, standard deviation). These methods provide a summary of the data, often through the use of graphical representations such as histograms, bar charts, and scatter plots.

The goal of descriptive methods is to understand the underlying structure of the data, identify patterns, and present the data in a clear and meaningful way.

Descriptive methods do not make inferences about a population based on a sample or draw conclusions about causality.

Answer:

Since this season, the probability that the Yankees will win a game is 0.6 The probability that the Yankees will lose when they score 5 or more runs is 19.2%.

Step-by-step explanation:

Since this season, the probability that the Yankees will win a game is 0.6 and the probability that the Yankees will score 5 or more runs in a game is 0.48, and he probability that the Yankees lose and score fewer than 5 runs is 0.33, To determine what is the probability that the Yankees will lose when they score 5 or more runs, the following calculation must be performed:

(1 - 0.6) x 0.48 = X

0.40 x 0.48 = X

0.192 = X

0.192 x 100 = 19.2

Therefore, the probability that the Yankees will lose when they score 5 or more runs is 19.2%.

The union of events A and B is the event containing: c. all the sample points belonging to A or B or both. The union of events reflects all possible outcomes for two events.

The correct option is (c)

In statistics, an event is also referred to as an outcome. For example, getting a head on a coin flip is an event. Getting a tail is also event. Viewed collectively, they are complementary events (meaning, one cannot occur if the other does, and their probabilities sum to 1.0).

Union of events: The union of events A and B, denoted by A ∪ B, consists of all outcomes that are in A or in B or in both A and B.

The correct option is (c).

The estimated current total cost for the installed and insulated tank is $12,065.73.

The first step is to calculate the surface area of the tank. The surface area of a cylinder is calculated as follows:

surface_area = 2 * pi * r * h + 2 * pi * r^2

where:

r is the radius of the cylinder

h is the height of the cylinder

In this case, the radius of the cylinder is 1 meter (half of the diameter) and the height of the cylinder is 1 meter. So the surface area of the tank is:

surface_area = 2 * pi * 1 * 1 + 2 * pi * 1^2 = 6.283185307179586

The insulation will add a thickness of 0.05 meters to the surface area of the tank, so the total surface area of the insulated tank is:

surface_area = 6.283185307179586 + 2 * pi * 1 * 0.05 = 6.806032934459293

The cost of the insulation is $40 per square meter and the cost of labor is $95 per square meter, so the total cost of the insulation and labor is:

cost = 6.806032934459293 * (40 + 95) = $1,165.73

The original cost of the tank was $10,900, so the total cost of the insulated tank is:

cost = 10900 + 1165.73 = $12,065.73

Therefore, the estimated current total cost for the installed and insulated tank is $12,065.73.

The value of the angle ∠ECF=37

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°

Given here: Two triangles DCE and ACB with C as the common vertex

Now in triangle ACB we have

∠A=53 and ∠B=45

Thus ∠A=180-53-45

              =82°

Now in triangle GCB we have ∠G=90

Thus ∠GCB=180-90-45

                   =45

And in triangle GCA we have

∠GCA= 180-90-53

The value of x will be greater than or equal to 130.

Inequalities in mathematics specify the connection between two non-equal quantities. Not equal is what inequality means. Typically, we use the "not equal symbol ()" to denote an inequality between two numbers. However, a variety of inequalities are employed to compare the values, whether they are less than or more than.

Given : 65 less than x is at most -65

which means, 65 - x ≤ -65

We get,  65+65 ≤ x

The ratio of dividends to the average number of common shares outstanding is known as the dividend yield. It is a measure of the return on an investment in the form of dividends received relative to the number of shares held.

To calculate the dividend yield, you need to divide the annual dividends per share by the average number of common shares outstanding during a specific period. The annual dividends per share can be obtained by dividing the total dividends paid by the number of outstanding shares. The average number of common shares outstanding can be calculated by adding the beginning and ending shares outstanding and dividing by 2.

For example, let's say a company paid total dividends of $10,000 and had 1,000 common shares outstanding at the beginning of the year and 1,500 shares at the end. The average number of common shares outstanding would be (1,000 + 1,500) / 2 = 1,250. If the annual dividends per share is $2, the dividend yield would be $2 / 1,250 = 0.0016 or 0.16%.

In summary, the ratio of dividends to the average number of common shares outstanding is the dividend yield, which measures the return on an investment in terms of dividends received per share held.

Answer:

a) Expected real interest rate = 4%

b) Actual real interest rate = 3%

c) If the inflation rate turns out to be higher than expected, Sally (the borrower) is better off.

d) If the inflation rate turns out to be lower than expected, Harry (the lender) is better off.

Let's see further:

a) To calculate the real interest rate, we subtract the expected inflation rate from the nominal interest rate:

Expected real interest rate = Nominal interest rate - Expected inflation rate

Expected real interest rate = 8% - 4%

Expected real interest rate = 4%

b) To calculate the actual real interest rate, we subtract the actual inflation rate from the nominal interest rate:

Actual real interest rate = Nominal interest rate - Actual inflation rate

Actual real interest rate = 8% - 5%

Actual real interest rate = 3%

c) If the inflation rate turns out to be higher than expected, Sally (the borrower) is better off. This is because the actual inflation erodes the value of money, reducing the real burden of repaying the loan.

d) If the inflation rate turns out to be lower than expected, Harry (the lender) is better off. In this case, the purchasing power of the money he receives back is higher than anticipated, resulting in a higher real return on his loan.

The actual inflation rate of 5% resulted in an actual real interest rate of 3%, making Sally better off than expected, while Harry would have been better off if inflation had been lower than expected.

Beth got £12 than Amy.

Given the following data:

To find how much more Beth got than Amy:

First of all, we would have to solve for Beth's share from the money.

\(A : B = 3 : 5\\\\18 : B = 3 : 5\\\\\frac{18}{B} = \frac{3}{5}\)

Cross-multiplying, we have;

\(18\) × \(5\) = \(3\) × \(B\)

\(90 = 3B\\\\B = \frac{90}{3}\)

Beth, B = £30

\(Difference = 30 - 18\)

Difference = £12

The dragster, starting from rest and accelerating at 32 m/s², reaches a speed of 128 m/s after 4.0 seconds.

A dragster starting from rest means that its initial velocity is zero. The dragster's acceleration is given as 32 m/s². To determine the speed of the dragster after 4.0 seconds, we can use the equation of motion:

where:

v = final velocity

u = initial velocity (which is 0 m/s since the dragster starts from rest)

a = acceleration (32 m/\(s^2\) in this case)

t = time (4.0 seconds in this case)

Substituting the given values into the formula:

v = 0 + (32 m/\(s^2\))(4.0 s)

v = 0 + 128 m/s

v = 128 m/s

Therefore, the dragster is traveling at a speed of 128 m/s after 4.0 seconds of acceleration.

Answer:

  2. 26.2 m

  3. 117.2 cm

Step-by-step explanation:

You want the perimeters of two figures involving that are a composite of parts of circles and parts of rectangles.

The circumference of a circle is given by ...

  C = πd . . . . . where d is the diameter

The length of the semicircle of diameter 12.6 m will be ...

  1/2C = 1/2(π)(12.6 m) = 6.3π m ≈ 19.8 m

The two lighted sides of the rectangle have a total length of ...

  3.2 m + 3.2 m = 6.4 m

The length of the light string is the sum of these values:

  19.8 m + 6.4 m = 26.2 m

The length of the string of lights is about 26.2 meters.

The perimeter of the figure is the sum of four quarter-circles of radius 11.4 cm, and 4 straight edges of length 11.4 cm.

Four quarter-circles total one full circle in length, so we can use the formula for the circumference of a circle:

  C = 2πr

  C = 2π·(11.4 cm) = 22.8π cm ≈ 71.6 cm

The four straight sides total ...

  4 × 11.4 cm = 45.6 cm

The perimeter of the figure is the sum of the lengths of the curved sides and the straight sides:

  71.6 cm + 45.6 cm = 117.2 cm

The design has a perimeter of about 117.2 cm.

Additional comment

The bottom 12.6 m edge in the figure of problem 2 is part of the perimeter of the shape, but is not included in the length of the light string.

Answer:

(−3.5,−0.5)

Step-by-step explanation:

Answer:

(-7/2, -1/2) or in decimal (-3.5, -0.5)

Step-by-step explanation:

The midpoint of any two points in a 2D plane will have its x-coordinate as the average of the x-coordinates of the two points and its y-coordinate as the average of the y-coordinates of the two points

Let Xm and Ym be the x and y coordinates of the midpoint

We have the two points as (-5, 2) and (-2, -3)

Xm = (-5 + -2)/2 = -7/2

Ym = (2 + (-3)) = (2-3)/2 = -1/2

So the midpoint is at (-7/2, -1/2) or in decimal (-3.5, -0.5)
