Answer:

The median is 19.5 or 20 as a tangible value.

Step-by-step explanation:

The median is like the middle number in a data set. When there is an odd amount of numbers in the data set, just count both sides of the data set to find the odd one out - or the middle number. When there is an even amount of numbers in the data set (like in this problem) - you have to make a couple of your steps a little like the ones you would use to solve Mean. (Stay tuned for a lot of counting/adding/dividing in these types of problems.)

Sorry for this long answer that took ages to right - I was just making sure you understand ALL of these concepts well!

The Data set is: {32,15,6,18,21,40,10,24,8,21,11,23,12,24,36,24,17,29,16,15}

There are 20 numbers in the set.

*Tip: At first, the way the graph is shown in the picture, it threw me off because I don't know which order the numbers are supposed to be in due to the two boxes of 10. Then I remembered that it DOES NOT matter anyway!:

You are supposed to line the numbers up from acceding OR descending order.

SORTED Data set: {40, 36, 32, 29, 24, 24, 24, 23, 21, 21, 18, 17, 16, 15, 15, 12, 11, 10, 8, 6

}

That means that the closest numbers to being the middle one are 21, and 18.

This is what I meant before when I said that "When there is an even amount of numbers in the data set....make a couple of your steps a little like the ones you would use to solve Mean":

Find the AVERAGE of the two numbers.

*TIP: If that sounds familiar, that is very similar to a Mean average, a Slope, and the answer/point of intersection you would get from Rise over Run.

*Find the Median/average (the middle pair of numbers is divided by two) this way: 21+18 = 39. 39/2 (the 2 is the amount halfway between) = 19.5.

*TIP: If you need to calculate the other things you may need to calculate on this data set: The step of dividing by two is different than if you had to calculate Mean. If you had to calculate that but got mixed up like I did (I have not done these problems in 2 YEARS), you might THINK to add 21+18 = 39 then divide it by the count of 20. 39/20 = 1.95 - that is the WRONG answer and decimal place - a different on than what you need. If you had to calculate Mean, you would have to be stuck doing a thing that you might think is MEAN. Adding all this: {40, 36, 32, 29, 24, 24, 24, 23, 21, 21, 18, 17, 16, 15, 15, 12, 11, 10, 8, 6

}; together to make: the sum of 402. Next, divide: by 20. 402/20 = 20.1. This will give you: 20.1.

*To find Range: The smallest number is 6, and the largest is 40. 40-6 = 34. This is the range of the numbers in the data set and where it begins/ends.

*Lastly, to find the Mode, just count the numbers in the data set. The number that appears the MOST is your data set. 24 seems to be it (It had a 3-time appearance.) If more than one number appears most - they are ALL correct, and are ALL part of the answer. I.E., 21 and 15 both appear twice so the mode would be 21 AND 15 if the 24 appeared less often or was nonexistent.

*Tip: These types of data answers (mean, median, mode, range) can be used to be made into a chart or graph - such as a bar graph or pie chart. ALWAYS remember to put your data set in proper ASCENDING order no matter HOW MANY NUMBERS there are - from smallest to largest. (Rather than descending like I told you before, haha.) Not only does it make your work neater; you have a better chance of getting a good or better grade if you messed up elsewhere because you at least did the ranging correctly. ;)

ANYWAY...Your answer is:

The Median (number of service upgrades sold by the 20 employees) is 19.5; but since this is a number that is NOT money...round up or down (if the question tells you to) to the nearest whole number. In this case, since the .5 is a number that is either 5 or over, round up to .5 more, or *20*; since you can't REALLY have 19 and a HALF service upgrades, tee-hee.

* The Median (number of service upgrades sold by the 20 employees) is 19.5 - or (for the answer to make sense in a real-life context) 20.

- Thankfully, there are no outliers (numbers outside of the data value's range to mess things up with an extremely small or large number.

* Last tip: Out of Median, Mean, Mode and Ranger, Median and Mode can be the easiest one to figure out - keep practicing! Hope this helped! I would recommend taking a snip-it, desktop snap or picture of this page for future reference so you can look at these tips when your question has been up on Brainly for too long like I do. Good luck in math. Have fun and take care; God Bless! :) I'm tired, now LOL - I'm going to bed soon XD. :3

Light travels 9.45 \cdot 10^{15}9.45⋅10 15 9, point, 45, dot, 10, start superscript, 15, end superscript meters in a year. t

Anna [14]

We are given that the distance light travel is:

9.45 x 10^15 meters / year

And that there is:

3.15 x 10^7 seconds / year

So the distance light travels per second is:

distance = (9.45 x 10^15 meters / year) * (1 year / 3.15 x 10^7 seconds)

distance = 3 x 10^8 meters / second

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 1 intermediate stop on the way to New Y

Zolol [24]

Answer:

Algebra - Question related to graphs?

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times?

Dose that make sense?

1: Yes

Way out.

NY,S1,S2,S3,Ch

Way back

Ch,S4,NY

The Ch is the same therefore total is 7.

2:

a(n)=-6+(n-1)(6)

3: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times.........

4: A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

i guess it would be 7 as the answer because: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times.........

Step-by-step explanation: Different Brainly's

1: Answer: 7

Step-by-step explanation: The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.

So, cumulatively the altitude will touch the horizontal axis seven times.

2: I Don't Know

3: Answer:

5 is the right answer

Step-by-step explanation:

The graph will touch the horizontal x each time the altitude is zero.

Tha happens: 1st in Chicago before taking off, 2nd, in the intermediate place before getting to NY, 3rd in NY, 4th in the intermediate place before getting to Ch, and 5th when arrives to Ch.

4: Answer:

7

Step-by-step explanation:

The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.

So, cumulatively the altitude will touch the horizontal axis seven times.

Can someone please help me answer this? 2x2 + x -21

Readme [11.4K]

Answer:

(x - 3)(2x + 7)

Step-by-step explanation:

Assuming you require the expression factorised.

Given

2x² + x - 21

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 21 = - 42 and sum = + 1

The factors are - 6 and + 7

Use these factors to split the x- term

2x² - 6x + 7x - 21 ( factor the first/second and third/fourth terms )

= 2x( x - 3) + 7(x - 3) ← factor out (x - 3) from each term

= (x - 3)(2x + 7) ← in factored form
