earle bailey has 20 songs to choose from but can play only 7 in the next half-hour on sirius xm classic.how many different (ordered) playlists are possible

Answers

Applying combination, the number of playlist is: 75,435.

How to Apply Combination to Solve a Problem?

A combination is a way of selecting a certain number of items from a larger set, without regard to the order of the items.

The number of possible playlists would be the number of ways to select 7 songs out of 20 without regard to order, which is commonly known as a combination.

The formula for combination is nCr, where n is the total number of items and r is the number of items being chosen at a time. So in this case, the number of possible playlists would be 20C7.

give three points that lie on a line with a slope of -2/5

Answers

The three points that lie on a line y = -2/5x with a slope -2/5 will be:

(0, 0)

(5, -2)

(10, -4)

How to illustrate the slope?

Given slope = m = -2/5. We suppose the line passes through the origin, so b = 0

substituting m = -2/5 and b = 0 in the slope-intercept form

y = -2/5x + 0

y = -2/5x

Thus, the equation of line with the slope m = -2/5 and passes through the origin (0, 0) will be:

y = -2/5x

As the equation of line passes through (0, 0), thus the point (0, 0) lies on the line.

Putting x = 0 in the equation y = -2/5x

y = -2/5 × (0)

y = 0

Thus, (0, 0) is the point which also passes through the line

Putting x = 5 in the equation y = -2/5x

y = -2/5 × 5

y = -2

Thus, (5, -2) is the point which also passes through the line.

Find the measures of the numbered angles.

Answers

Answer: ∠1= 75°, ∠2= 105°, ∠3=105°, ∠4=75°, ∠6=105°, ∠7= 105°, ∠8=75°

Step-by-step explanation:

∠1 is corresponding to angle 75° which make them equal.

∠2 is supplementary to ∠1 which means they add up to 180°. Since ∠1 is 75° you would subtract 75° from 180° to get 105°.

∠3 is vertical to ∠2 which makes them equal.

∠4 is vertical to ∠1 which makes them equal.

Answers

Based on a survey of 2718 people, a research center concluded that 32% of Americans "always" make a special effort to sort and recycle glass, cans, plastic, or papers. Participation bias is there in this case.

The bias would have no effect on a reader's perception of the assertion because no group of persons is much more likely to respond to the poll than any other.

When comparisons are performed between groups of patients who differ in outcome determinants and the differences are connected to the result, participation bias emerges.

1. Participation bias is inherent in studies that involve participant enrollment.

2 Because selective participation might jeopardize study external validity, determining the magnitude of participation bias is critical for optimizing inference from these investigations.

Answers

A) The measure of the central angle is [tex]\frac{4}{3} \pi[/tex] .

B) The radius of the circle is 55.43 in.

A) We know,

The area of a sector is [tex]\frac{n}{2\pi } \pi R^{2}[/tex]

where n = the degree of the central angle of the sector

R = radius of the circle

Suppose, the measure of the central angle is x.

[tex]\frac{x}{2\pi } .\pi .24^{2} = 384\pi[/tex]

⇒ [tex]\frac{x}{2\pi } = \frac{384\pi }{576\pi }[/tex]

⇒ [tex]x = \frac{384\pi }{576\pi } * 2\pi[/tex]

⇒ [tex]x = \frac{4}{3} \pi[/tex]

So, the measure of the central angle is [tex]\frac{4}{3} \pi[/tex].

B) Suppose the radius of the circle is r in.

[tex]\frac{\pi /4}{2\pi } .\pi .r^{2} =384\pi[/tex]

⇒[tex]\frac{1}{8} .\pi .r^{2} =384\pi[/tex]

⇒ [tex]r^{2} = 384\pi / \frac{1}{8} \pi[/tex]

As r > 0

So, r = 55.43

Second step: multiply the place values and add the results to the table. Step 3: Add up all of the table's rows. Step 4: Add the sums of these rows.

Placing the first word in the first box and the last term in the last box is the first step in utilizing the box technique to factor a trinomial. Multiply the first and last boxes after that.

Answers

The small boy can use the mathematical reasoning of similar triangles and the concept of ratios to determine the height of the light post.

Similar triangles are triangles that have the same shape but can have different sizes. In this case, the shadow of the boy, the boy himself, and the light post form similar triangles.

Let h be the height of the light post, x be the distance between the boy and the light post, and s be the length of the shadow, we can use the following ratios -

(boy's height) / (boy's shadow) = (light post height) / (light post shadow)

i.e. (4 feet 6 inches) / (3 feet 4 inches) = (h) / (x)

Now, we can find the height of the light post by using the above equation and the given values of the boy's height and the shadow.

The small boy can measure the distance between him and the light post, and he can use this value in the above equation to determine the height of the light post. The equation is h/x = (4.5)/(3.33)

This is the ratio of the height of the light post and the distance between the boy and the light post, so h = (4.5 * x) / (3.33)

In this way, the small boy can use the mathematical reasoning of similar triangles and the concept of ratios to determine the height of the light post.

We are required to use the mean, median and mode to explain which measure of central tendency best describes the monthly rent.

The mean, median and mode (as calculated) are the measures of central tendency for the data set given.

This measures which value is closest to the center such that it can conveniently represent every other data. Observe carefully that the least value is 670 while the highest is 1550.

Also, observe that the value which is "more central" to both extremes is the mean.

The median is closer to the lowest value and much farther from the highest value.

The mode is actually at the lowest end of the data set.
