What is 4^2y-3^2=-5y+(-5+7)<br> Please explain step by step i need this asap :/
dybincka [34]

y = 11/21

To solve this first evaluate the power (then calculate the sum):

<u><em>4^{2}</em></u>y - <u><em>3^{2}</em></u> = 5y +<u><em> (-5 + 7)</em></u>

16y - 9 = -5y + 2


Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):

16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2

16y + 5y = 2 + 9


Next Collect the like terms and calculate the sum:

<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>

21y = 11


Lastly divide both sides of the equation by 21:

<u><em>21y = 11</em></u>

y = \frac{11}{21}

Create a dot plot of the data shown below. 20, 21, 21, 25, 20, 23, 27, 23, 24, 25, 26, 24, 23, 22, 24 Which measure of center wo
JulijaS [17]

The measure of center that would best describe a typical value of the data set is a mean since the values are close.

<h3>What is a measure of center?</h3>

It should be noted that the measure of center include the mean, median, mode, and the mid-range.

In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.

Therefore, the mean of the numbers will be:

= (20 + 21 + 21 + 25 + 20 + 23 + 27 + 23 + 24 + 25 + 26 + 24 + 23 + 22 + 24)/15

= 348/15

= 23.2
