Mathematics
1 answer:
lbvjy [14]3 years ago
3 0

Answer:

0.024

Step-by-step explanation:

Given,

Red marbles = 4,

Green marbles = 7,

Total marbles = 4 +7 = 11,

Ways of choosing 3 marbles =^{11}C_3

Ways of choosing 3 red marble = ^4C_3

Hence, the probability of 3 red marble = \frac{^4C_3}{^{11}C_3}

=\frac{\frac{4!}{3!1!}}{\frac{11!}{3!8!}}

=\frac{4}{165}

≈ 0.024

Jamar has a points card for a movie theater.
netineya [11]

Answer:

He needs to make at least 6 visits.

Step-by-step explanation:

The signing up amount, 20, is a fixed amount.

The amount he receives per movie is 12.5 times the number of visits, v, or 12.5v.

The total amount of points he earns is the sum of the fixed amount and the amount due to the number of visits.

earned points = 12.5v + 20

He must earn 95 points or more.

12.5v + 20 ≥ 95

Subtract 20 from both sides.

12.5v ≥ 75

Divide both sides by 12.5

v ≥ 6

He needs to make at least 6 visits.

If m∠NOP = 24° and m∠NOQ = 110°, what is m∠POQ?
monitta

Correct answer for the above question is - option B. 86°

<u>Step-by-step explanation:</u>

Given:

∠NOP = 24°

∠NOQ = 110°

∠NOP and ∠POQ are adjacent angles

To Find:

∠POQ = ?

Solution:

Hereby, we can say that ∠POQ lies between line OQ and ON as given (∠NOP and ∠POQ are adjacent angles )

∠NOQ - ∠NOP = ∠POQ

∠POQ = 110° - 24°

<u>∠POQ = 86°</u>

Angle POQ is  86°

Thus we can conclude option B as correct answer.
