Answer:
2x + 3y + 5z = 9
Step-by-step explanation:
The normal defines all the planes perpendicular to that vector. To isolate to a single plane, just apply the known point.
ax + by + cz = d
2x + 3y + 5z = d
2(1) + 3(-1) + 5(2) = 9
1 is 90o
2 is 90 - 27 = 63
3 63 angles 2 and 3 are in an isosceles triangle. They are opposite equal sides so the angles are equal.
Answer:
Conditional relative frequency = 0.67
Step-by-step explanation:
50% off Buy 1, get 1 free Total
Item 1 12 8 20
Item 2 20 10 30
Total 32 18 50
Condition relative frequency table:
50% off Buy 1, get 1 free Total
Item 1

Item 2

Total

Therefore, conditional relative frequency of selling an item marked 50% off, provided the item sold is item 2 = 0.67
