Answer:

6. 15/22

7. 1/12

9. 1/16

10. 0

Step-by-step explanation:

6. 10 of the 12 tiles are "not P", so the probability of a "not P" on the first draw is 10/12 = 5/6. After drawing a "not P" on the first draw, 9 of the remaining tiles are "not P". The probability of drawing one of those is 9/11. So, the joint probability of drawing two "not P" tiles is ...

(5/6)(9/11) = (5·9)/(6·11) = 15/22

7. The probability of drawing a tile worth 3 points is 3/12 = 1/4. The probability of drawing a tile worth 1 point is 4/12 = 1/3. So, the joint probability of drawing a 3-point tile, then a 1-point tile is ...

(1/4)(1/3) = 1/12

9. There are 3 of the 12 tiles worth more than 4 points. The probability of drawing one of them is 3/12 = 1/4. The probability of doing it again is also 1/4, so the probability of doing it twice is ...

(1/4)(1/4) = 1/16

10. The probability of drawing a Z is 1/12. Having drawn a Z, the probability of drawing a 10-point tile is 0/11. The joint probability of drawing a Z twice is ...

(1/12)(0/11) = 0

Two neighbors in a rural area want to know the distance between their homes in miles. Help 'em out! 1 mile = 5,280 feet. Find the distance between their houses in miles. (i have 69 points left so PLEASE PLEASE dont be rude and answer like this ¨ssieoiej¨)

Answers

Answer:

4/5 OR 0.8

Step-by-step explanation:

Divide the distance between them by 5,280. You should then get a decimal of 0.8. Not sure if you are looking for decimal or fraction, but 0.8 as a fraction is 4/5. So 4/5 of a mile is in between their two houses. Hope this helps :)

Answer: 634 sq meters

Step-by-step explanation:
Its alittle bit too complicated to explain.

1. 36-29 = 7
2. 18-14 = 4
3. 7 x 4 / 2 = 14
4. 14 x 7 = 98
5. 18 x 29 = 522
6. 14 + 98 + 522 = 634
So the area of the polygon is 634 sq meters (I didn't double check.)
