3 people wearing both are also counted in the 6 with socks and 4 with shoes so you can't count them twice. What you do in stead is list :
<span>3 wearing both </span>
<span>4 - 3 = 1 wearing just shoes </span>
<span>6 - 3 = 3 wearing just socks </span>
<span>total 7 so far so that leaves 5 others that must be barefoot.</span>
Answer:
-82
Step-by-step explanation:
Maybe you want the determinant of ...
![\left[\begin{array}{cc}5&9\\8&-2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D5%269%5C%5C8%26-2%5Cend%7Barray%7D%5Cright%5D)
The determinant of a 2×2 matrix is the difference of the products of elements on the down diagonal and the up diagonal:
D = (5)(-2) -(8)(9) = -10 -72 = -82
The determinant of this matrix is -82.
(2^8x5^-5x19^0)^-2 x (5^-2/2^3)^4 x 2^28
(256x0.00032x1)^-2 x (0.04/8)^4 x 2^28
0.08192^-2 x 0.005^4 x 268,435,456
149.0116119384766 x 0.000000000625 x 268,435,456
0.000000093132257 x 268,435,456
= 25
