42,42,24,36,60,6<br> Find the sum of the differences squared between the data entries and the mean.
irakobra [83]
42,42,24,36,60,6

1st Find the mean  X̅ =(42+42+24+36+60+6)/6 = 35

2nd find the difference between the data set value and the mean (x - X̅)
and square them:
(42-35)² = 49
(42-35)² = 49
(24-35)² = 121
(36-35)² = 1
(60-35)² = 625
(6-35)² =  814
Now add up te result ∑(x-X̅)² =1659

Could someone pls help me out ???
professor190 [17]

Answer:

Option C.

Step-by-step explanation:

\sf\:x^{2}-3x+7=0

Use the biquadratic formula.

\sf\:\x=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 7}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-4\times 7}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-28}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{-19}}{2}

\sf\:x=\frac{3(+/-)\sqrt{19}}{2}

Positive sign:

\boxed{\sf\:x=\frac{3+\sqrt{19}}{2}}

Negative sign:

\boxed{\sf\:x=\frac{3-\sqrt{19}}{2}}

Hope it helps ⚜
