In the given figure, NQ acts as a diameter and since diameter subtends 90° at the arc of the circle, so we can conclude that ~
Now, Let's use Angle sum property of Triangle to solve for z :
I hope you understood the procedure, you can ask me in comments if you have any doubts.
Answer:
BC = 35in.
Step-by-step explanation:
AD says the entire line is 53in.
AB says it is equal to CD.
CD says it equals 9in so AB + CD = 18in.
BC says it equals 5x.
AB+BC+CD = AD
(9) + (5x) + (9) = 53
5x + 18 = 53
<em>Subtract 18 from both sides</em>
5x = 35
<em>We can stop here because we know that BC = 5x and 5x = 35in.</em>
35%
Using the experimental probability of 7 pennies (a success) out of 20(number of trials) can give us an estimate of 7/20 or 0.035 or 35%
Answer:
2/91.
Step-by-step explanation:
There are 15 marbles in the bag.
Prob(First draw is red) = 5/15 = 1/3.
Prob(Second draw is red) = 4/14 = 2/7.
Prob(Third draw is red) = 3/13.
So probability that all 3 are red = .1/3 * 2/7 * 3/13
= 6/273
= 2/91.
