Step-by-step explanation:
What question are you referring to
The cross product is perfect for this purpose.
The cross product C of vectors p and q is orthogonal to both p and q.
C will then be scaled to have the first value equal to 7 to find b and c.
C=<1,2,3>x<1,-2,1>
=
i j k
1 2 3
1 -2 1
=<2*1+3*2, -(1*1-1*3), 1*(-2)-1*2>
=<8, 2, -4>
=2<4,1,-2>
=(8/7)<4*7/4, 1*7/4, -2*7/4>
=(8/7)<7, 7/4, -7/2>
So b=7/4, c=-7/5
Check:
<7,7/4,-7/2>. <1,2,3>=7*1+7/4*2-7/5*3=7+7/2-21/2=0 .... ok, orthogonal
<7,7/4,-7/2>.<1,-2,1>=7*1-7/4*2-7/2*1=0 ..........................ok, orthogonal
Answer:
C. 1/6
Step-by-step explanation:
The experimental probability is the probability that is obtained by dividing the number of times the required outcome has occurred by the total number of trials.
In the experiment given the color red is one of the six possible outcomes and the next time the experiment is performed the number of trials would be 1
so the experimental probability would be 1/6
If the previous number of trials were given then the probability would have been different.
