It’s a median of 9 sorry if I’m wrong

<h2>Answer:</h2>

x = 8

y1 = 17

y2= 20

<h2>Step-by-step explanation:</h2>

Taking what we know, which is the median, and the mean.
The mean is the average of all the numbers added together then divided.
The Median is the middle number. This means we can easily solve what x equals.

knowing the middle point is 9. x has to be 8 so because there are 6 numbers, and no numbers in the middle of the positions 3-4.

Now we need to solve for both the final numbers, which in this has to come to an average of 11, and knowing the numbers are all ascending, we can at least come to the conclusion that the numbers are all < 10. Which leads us to the guessing part which is most likely not the best way to solve this, but is how I would solve it, and is just by plugin in numbers and solving. Which I found could be 17 and 20, as with both the median still is equal to 11.

PLEASE HELP URGENT<br><br> Given \tan \theta =0.6, find the value of b.

xxTIMURxx [149]

Answer:

b=8.5cm

Step-by-step explanation:

tanx (this represents tan theta, it's just easier to type) is equal to 0.6 and since the tanx ratio is opp/adj, we know that opp/adj = 0.6

To find what b is (adjacent as it is adjacent to the angle being used and it is not the hypotenuse), we just have to rearrange.

0.6=5.1/adj

to solve for adj, we can switch 0.6 and adj. (This works because to get adj by itself on one side you would multiply it to the other side and then divide 0.6 from both sides --> simple algebra)

so then you have

adj=5.1/0.6

adj=8.5cm

(if you want to check your solution you can use pythagoeran theorem, a^2+b^2=c^2) and sub everything in and make sure all the numbers equal the right thing!

Can anybody explain to me what is being done here ?

Answer:

So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with

3/1 times x = 2193

3/1 just equals three, so you write it down as 3.

3x = 2193

To isolate 3x, you need to divide by 3.

x = 731

Hope this helped :)
