Differentiate with respect to t

True [87]

Answer:

$\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0$

Step-by-step explanation:

We want to differentiate the equation:

$x^2-y^3+z^4=1$

With respect to <em>t</em>, where <em>x, y, </em>and <em>z</em> are functions of <em>t. </em>

<em />

So:

$\displaystyle \frac{d}{dt}\left[x^2-y^3+z^4\right]=\frac{d}{dt}\left[1\right]$

Implicitly differentiate on the left. On the right, the derivative of a constant is simply zero. Hence:

$\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0$

FInd the mean, median, mode for the following data:

Anettt [7]

Answer:

Mean : 16

Median: 15.5

Mode: 16

Step-by-step explanation:

<u><em>Given/To Find:</em></u>

<em>Find the mean, median, mode for the following data:</em>

<em>10, 10, 12, 13, 13, 14, 15, 16, 16, 16, 18, 22, 23, 26</em>

<u><em>Solve:</em></u>

<em>Mean: Average</em>

<em>Formula: Adding all number in data then divide by the total number in data.</em>

<em>10 + 10 + 12 + 13 + 13 + 14 + 15 + 16 + 16 + 16 + 18 + 22 + 23 + 26 = 224</em>

<em>224/14 = 16</em>

<em>Median: Middle Number</em>

<em>Formula: Number in the middle</em>

<em>10,</em><em> 10, 12, 13, 13, 14, 15, 16, 16, 16, 18, 22, 23,</em><em> 26</em>

<em>10, 10,</em><em> 12, 13, 13, 14, 15, 16, 16, 16, 18, 22, </em><em>23, 26</em>

<em>10, 10, 12,</em><em> 13, 13, 14, 15, 16, 16, 16, 18, </em><em>22, 23, 26</em>

<em>10, 10, 12, 13,</em><em> 13, 14, 15, 16, 16, 16, </em><em>18, 22, 23, 26</em>

<em>10, 10, 12, 13, 13, </em><em>14, 15, 16, 16, </em><em>16, 18, 22, 23, 26</em>

<em>10, 10, 12, 13, 13, 14, </em><em>15, 16, </em><em>16, 16, 18, 22, 23, 26</em>

<em>15 + 16 = 31</em>

<em>31/2 = 15.5</em>

<em>Mode: Most often number: 16</em>
