The following are the steps involved in finding the mean of the data.
$$ \begin{array}{|c|c|c|c|c|c|} \hline \mathrm{x} & 10 & 8 & 6 & 4 & 2 \\ \hline \mathrm{f} & 1 & 3 & 5 & 7 & 9 \\ \hline \end{array} $$
Arrange them in sequential order. (a) $\therefore$ Mean $=\frac{\sum \mathrm{fx}}{\sum \mathrm{f}}=\frac{110}{25}$ $\Sigma \mathrm{f}=1+3+5+7+9$ (b) $\Sigma \mathrm{fx}=10+24+30+28+18$ (c) $\therefore$ Mean $=4.4$ (d) $\Sigma \mathrm{fx}=110$ and $\Sigma \mathrm{f}=25$ (1) abdc (2) acbd (3) bdac (4) bcad

Hello Syringe here in this question we have given a data which is 598 12 7 13, 10 and 14. Okay. For this data we need to find the means of the Cuban if you do. And Q three. Okay. Q 1 to 2 to three. Rd quarter into the first quarter. Second quarter and a third quarter. So for finding Cuban to 23. 1st of all, we need to arrange their data in ascending order. Okay? So if we arrange the data in ascending order then it comes out to be 57 89 then 1213 and 14. So this is our data. So first of all we'll find the value of cuba. Okay, Cuban is a lower court. Lower quartile is given by And Plus one x 4 Tom. Okay. And plus one by fourth tom is all lower quality. Okay. So if we see the value of end for this data is eight. Right? There are eight. A number of data's Okay, so the value of N is eight. So if we put here then Q one comes out to be two point tools down. Okay, so this is a fractional town, how we'll find it. What we'll do is We'll take 2nd town as it is. Okay. And plus will multiply it by zero point to fight. That is the remaining part with the third. 3rd Data -2 Data. This is the formula for finding the fractional to barter. It's okay. So the second term is seven plus 0.25 times of the third time, which is eight minus the second damages seven. So quartile one that is lower. Quartile comes out to be 7.25 Okay. Now for the second quarter will just do the same procedure. Okay? Second quarter is also called the meeting of the data but we'll find a better formula of quarter. It's okay. So quartile. Second quarter is given by and plus one by four, multiplied by two. Okay, for one will multiply by one. For second quarter will multiply by two ft are quite I will multiply by three. Okay, so this town will give us the second quarter, so if we put the value of and it comes out to be 4.5, okay, four points of trump believes as the quartile too, so it is also the fictional town. So what we will do is fourth trump Plus 0.5 multiplied by 5th -4 Jump. Okay, this is the formula. So if we look at the data, fourth thomas, 4th time is nine Okay, and the system is 10 So forth, Thomas nine Plus 0.5 Times off. First time is 10 and fourth time is nine. Okay, so it comes out to be 9.5 so cartel to comes out of the 9.5. Okay, now the last part remaining. A Squat L three. Okay. Support squad L three for quartile three. What will be the formula and plus one by four. Multiply by three at this time. Well, diversity quite entry. Now putting the value of and it comes out to be 27 by four. Okay, this time that means it is 6.72. Okay. Now you can easily uh Tell what will be the 6.75 jump. It will be the sixth time plus 0.75 times off. Seventh trump minus the sixth time. Right? This will the formula for 6.7 at the time. So putting the value the sixth time is 12 plus seventh. Tom is 13 and six time is 12. The difference comes out of the one might have a 0.753 by four. So it comes out of the 12.700. Okay, so quartile three is 12.75 Now we need to find the mean of all these quarterbacks. Okay. So I mean of all the squad tiles will be Cuban plus kill. Do plus Q three Divided by three paid. So Cuban was 7.25. Right? And Kyoto was 12.75 and Q three uh, was 9.5. Okay. Sorry. Koda was 9.5 inch of this. 12.75 Okay, divided by three. Now it comes out to be 29.5. If you calculated 29.5, that means me Comes out to be nine point it. Okay, so this is the answer. Thank you.

So here we are, given a data set, were asked to find the main median and mode of this given set, which is 10 12 2015 and 20. So first, to find the main, which is X bar, is able to x y, which are data points over and which is our number. So here we would add up 10 plus 12 plus 20 plus 15 plus 20. And then divide that by five. Forget this a mean value of 15.4. Mhm, mhm. Next we want to find the median. Yeah, yeah, which is the middle value. So we're going to want to add our Liston in order from greatest police. So we have 20 15, 2 twenties, 15, 12, 11, 10. So here are median is 15. Yeah, and last. We want to find the mode, which is just the most. It's a good way to think of it. So again, listing out our data set, you can see that the only number that really repeats is 20. So our mode will be 20 Mhm

This question gives you a list of numbers and asks you to find the mean. The numbers that give you are 38,500 39,007. 20. 42,183. 21,982 and 43,250 Now we know that the formula for the mean or X bar is of some of all our data points we right, that is the sum of X. I divided by en now n is just the number of data points and we can count him up here to see that and is equal to five. And we plug these into a calculator will find that the sum of all the state of points is equal to 185,000 635. Now that means that X bar, or the mean is just 185,635 divided by five. The calculator tells me that that is 37,127. That is your final

If we want to find me every day to set, we need to find some but values in the dates up and divide this by the total number of values. Great Uncle, if we leave the base sup 15 seven So 19 27 17 19 1st 5 in 20. Find the mean. The first thing we need to do is to find some of all these values by having them would pay 15 plus seven post well close. 19 27 17 19 35 This 20 all divided by the total number values which in the taste is on 23456789 Beyond simple. For that it was 171 is the total sum of values favor. Nine. This Devine's give us me, but in the States is 19. So the mean of this status that is 19

An electron of mass $9.11 \times 10^{-31} \mathrm{kg}$ has an initial speed of $3.00 \times 10^{5} \mathrm{m} / \mathrm{s} .$ It travels in a straight line, and its speed increases to $7.00 \times 10^{5} \mathrm{m} / \mathrm{s}$ in a distance of $5.00 \mathrm{cm} .$ Assuming its acceleration is constant, (a) determine the force exerted on the electron and (b) compare this force with the weight of the electron, which we neglected.
