The answer in fraction form is exactly 1/13
The approximate answer in decimal form is 0.076923
To get this answer, note how there are four cards that have "2" on them. This is out of 52 total. So we divide the values: 4/52 = 1/13. Don't forget to fully reduce as much as possible.
To go from 1/13 to 0.076923, you would use a calculator or long division
Answer:
-19,531,250
Step-by-step explanation:
multiply the last term by -5
You know that three points A,B,CA,B,C (two vectors A⃗ BA→B, A⃗ CA→C) form a plane. If you want to show the fourth one DD is on the same plane, you have to show that it forms, with any of the other point already belonging to the plane, a vector belonging to the plane (for instance A⃗ DA→D).
Since the cross product of two vectors is normal to the plane formed by the two vectors (A⃗ B×A⃗ CA→B×A→C is normal to the plane ABCABC), you just have to prove your last vector A⃗ DA→D is normal to this cross product, hence the triple product that should be equal to 00:
A⃗ D⋅(A⃗ B×AC)=0
Your answer is that last one 8 3/4
45/ 6= 7.5
you can not have half a box
so 8
