Due tonight and I’m so worried.

3: Line AD

4: Line Segment AD

5: Point H

Step-by-step explanation:

For #3, because plane ABC and AEH are both planes that go in every direction infinitely, All points on line AD intersect.

For #4, because line segment AD is contained inside of the same plane of ABC, The entire line segment intersect.

For #5, Both lines meet at point H.

0.43.

Step-by-step explanation:

The probability that the customer will pay with debit card = 50%

The percentage of customers who use coupons 30% and  35% pay with debit card.

Now calculate the probability  that the same person will use coupon:

P[Uses coupons | Pays with Debit card] = P[Uses coupons and pays with debit card] / P[ Pays with debit card]

= 0.3 * 0.5 / 0.35

= 3/7  or  0.4286 or 42.86%
