Nine point two one zero five
Ben has mixed up the digit for millions and hundred thousands: he wrote 5
in the place for millions and 6 in the place for hundred thousands, but
it should be the other way. I think that he should exchange those two digits in the faulty report.
19.445 is the answer as you can see...
first you need to see the 1 decimal place which is like the number smaller than 1, eg:0.5,0.4 then later you see the 2 decimal place and later third on order to find out...
Red is 20 and you spin it 50 times so 2/5 chance is red so that makes 3/5 chance not red
We need the cross product of the two vectors.
a x b
=<2,-2,-3> x <3,2,2>
=
i j k
2 -2 -3
3 2 2
=<-4+6, -(4+9), 4+6>
=<2,-13,10>
The second vector is obtained by reversing the direction, namely <-2,13,-10>
Thus the two vectors are <2,-13,10> and <-2,13,-10>.
