if (5,k) is a solution of 2x+y-6=0,then find the value of k.

This measure of central tendency can be considered the most precise in option c. mean

The mean is a measure of central tendency that calculates the average of a set of values. It is often considered the most precise measure because it takes into account all the values in the dataset and provides a balanced representation.

The mean is calculated by summing all the values and dividing by the total number of values. Unlike the mode, which only identifies the most frequently occurring value, and the median, which represents the middle value, the mean incorporates all the values and provides a comprehensive summary of the dataset.

However, it is important to note that the mean can be sensitive to extreme values or outliers in the data.

The angle x in the diagram is 98 degrees.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angle, alternate exterior angles, vertically opposite angles, same side interior angles etc.

Therefore, let's find the angle of x using the angle relationships as follows:

The size of the angle x can be found as follows:

82 + x = 180(same side interior angles)

Same side interior angles are supplementary.

Hence,

82 + x = 180

x = 180 - 82

x = 98 degrees

The calculated percentiles are as follows:

10th percentile: 21

50th percentile (Median): 40

100th percentile: 115

To calculate the 10th, 50th (also known as the median), and 100th percentiles from the given set of observations: 42, 29, 40, 21, 115, we need to sort the data in ascending order.

Ascending order: 21, 29, 40, 42, 115

Now we can calculate the desired percentiles:

10th percentile: The 10th percentile is the value below which 10% of the data falls. To calculate it, we multiply 10% (0.1) by the total number of observations (5) and round up to the nearest whole number. In this case, 10% * 5 = 0.5, which rounds up to 1. Therefore, the 10th percentile is the first observation in the sorted data, which is 21.

50th percentile (Median): The 50th percentile represents the middle value of the data set when arranged in ascending order. Since we have an odd number of observations (5), the median will be the middle value. In this case, the middle value is the third observation, which is 40.

100th percentile: The 100th percentile represents the maximum value in the data set. Since the maximum value in the given data set is 115, it is also the 100th percentile.

Therefore, the calculated percentiles are as follows:

10th percentile: 21

50th percentile (Median): 40

100th percentile: 115

Answer:

Step-by-step explanation:

The question is not complete, here is the complete question

"DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"

1/4 of $48= 0.25*48=$12

so he thought he should pay $12

1/4 off $48= $48-$12= $36

now the difference is

36-12= $24

Let s =cost of skiing per day. Here's what we know:

450 + 20s = 64s + 20s (the season pass plus ski rentals equates to daily skiing plus ski rentals)

We have 20s on both sides, so those cancel out easily:

450 = 64s

Divide both sides by 64:

7.03 ≈ s

You can't pay for a partial day, so the skier will have to ski for at least 8 days to make the season pass cheaper than getting daily passes.

Answer:

\(\frac{n^{2}}{2a}\)

Step-by-step explanation:

Answer:

(n^2)/2a

Step-by-step explanation:

We'll take this in small steps. Don't worry and follow along if you wish :D

Where do we start? Well, first, we notice that all of the numbers/variables (on both the denominator and the numerator) are multiplied by each other. If this case had addition or subtraction in the fraction, the explanation would have differed.

Let's take on a simpler example to show you what I mean. Here's a relatively simpler equation with no pesky variables:

(1 + 3)/4

This equation has to be broken down like this:

1/4 + 3/4

And although we could just do (1 + 3) quickly and divide by 4, consider it if we replace them with numbers instead, or variables in other words:

(x + y)/x

Then, it would work the same way as the previous example:

x/x + y/x

And that would further simplify to (1 + y/x).

But, we're lucky! Because there is no addition or subtraction, we won't have to divide all the numbers that are in the numerator with the number(s) in the denominator. Consider this:

(3*4)/4

We only need to divide 4 by the denominator (which is also four, in this case) and not both 3 and 4 like how we would solve if it had addition or subtraction.

First step! Let's take all of the variables out of this nasty equation we have on our hands to make it simpler:

(9an^3)/(18a^2n)

We would be left with...

9/18

And then we would reduce to leave 1/2. Notice that if we add all the variables back, we would have:

(1an^3)/(2a^2n)

Or (an^3)/(2a^2n)

If we write it out, we'll find this equation a tad bit easier with the large numbers dealt with (although I will admit, it doesn't look that great on the screen—lol)!

Back to business. Here, we need to simplify the variables. Given, we have to remember that variables are just your every-day number (but unknown). Because of that, we get to divide them very much like how we would with regular numbers. Rope in some of our previous lesson about not having to divide all the numbers on the numerator from the denominator from the beginning, too!

(an^3)/(2a^2n)

You can cancel out the variable a^ in this equation. That would leave you with:

(n^3)/(2an)

Try to simplify the rest on your own and use my work to check your answers! if you can't, then no worries. Follow along with me :D

We can also reduce using n. That will leave:

(n^2)/2a

And then you're done! I would recommend more questions like these (if you aren't already doing them) because you'll be using simplifying techniques similar to this equation in the future.

Good luck and keep studying!

Answer:

-16.

Step-by-step explanation:

= -2 * 8

= -16.

When sampling without replacement, the standard deviation (SD) of a binomial distribution can be calculated using the following formula:

SD = sqrt((N - n) * p * (1 - p) / (N - 1))

where N is the population size, n is the sample size, and p is the probability of success (in this case, the proportion of echidnas with diets consisting mostly of termites).

Given that the population proportion of echidnas with termite diets is 40% (or 0.4) and the sample size is 20, we can calculate the standard deviation.

SD = sqrt((N - n) * p * (1 - p) / (N - 1))

= sqrt((N - 20) * 0.4 * (1 - 0.4) / (N - 1))

Since we don't have information about the total population size (N), we cannot calculate the exact standard deviation.

However, we can provide an estimation by assuming a large population, which means that the difference between N and N-1 is negligible.

Let's assume N is large, so N - 1 ≈ N:

SD ≈ sqrt((N - 20) * 0.4 * (1 - 0.4) / N)

≈ sqrt(0.24 * (N - 20) / N)

Given the answer choices provided, we can estimate the closest value to the standard deviation.

Let's substitute different values for N and find the closest answer choice.

For N = 100, we have:

SD ≈ sqrt(0.24 * (100 - 20) / 100)

≈ sqrt(0.24 * 80 / 100)

≈ sqrt(0.192)

≈ 0.438

For N = 200, we have:

SD ≈ sqrt(0.24 * (200 - 20) / 200)

≈ sqrt(0.24 * 180 / 200)

≈ sqrt(0.216)

≈ 0.465

Out of the provided answer choices, the closest value to the estimated standard deviation of 0.465 is 0.4.

Therefore, 0.4 is the closest choice to the standard deviation of x.

Answer:

Slope of line e is 2/3

Step-by-step explanation:

you know that equation for line d is y= 2/3x+3. because that line e is parallel to line d, it means that line e and d will never intersect which can only happen if both lines have the same slope. so that means line e's slope is 2/3

Answer:

2/3

Step-by-step explanation:

when a line is parallel to another line we say that the slopes are equal hence the slope of line e is 2/3.

NOTE: if a line is perpendicular to another the slope of line B the line is the negative reciprocal of the slope of Line A

for instance: if the slope was 2/3 the slope of the perpendicular line is -3/2

The length of BP is 14.4 meters.

To find the length of BP, we can use the property that states that when two chords intersect inside a circle, the product of the segment lengths on one chord is equal to the product of the segment lengths on the other chord.

Using this property, we can set up the equation:

AP * PC = BP * DP

Substituting the given values:

12 m * 6 m = BP * 5 m

Simplifying:

72 m^2 = BP * 5 m

To solve for BP, divide both sides of the equation by 5 m:

72 m^2 / 5 m = BP

Simplifying:

14.4 m = BP
