Using it's concept, the standard deviation of the data-set is of 34.2.

<h3>What are the mean and the standard deviation of a data-set?</h3>

  • The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
  • The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.

Having this in mind, and inserting the data-set in the calculator, it is found that:

  • The mean is of 83.4.
  • The standard deviation is of 34.2.

Solve for x parallel ​
umka2103 [35]

Answer:

x=5

Step-by-step explanation:

Hi there! So when it comes to these two angles, you have to set them equal to each other. From there, you have to isolate the x values, so I subtracted x from the 3x and added 15 to the -5. If you plug in the 5 for the x values, both give the value of 0, so it all checks out. I hope this helped! Please mark this as brainliest if I managed to get this correct. <3

Find the value of y when x equals 26 x+4y=54
pishuonlain [190]

Factor out the common term "2".

2(13x+2y) = 54

Now, divide both sides by 2.

13x + 2y = 54/2. <-- <u>We could not divide into a whole number so it's a fraction.</u>

<u />

Simplify 54/2 to 27.

13x + 2y = 27 <--- <u>Since we have a whole number without a letter, we are done with that side.</u>

<u />

Now, we subtract 2y from both sides.

13x = 27 - 2y

Divide both sides by 13.

x = 27 - 2y/13.

<h3>Therefore, we get <u>x = 27 - 2y/13</u></h3>

That would be our final answer.

Good luck on your assignment!
