What angle has the same sine value between 0-180? as Sin 24
Inessa05 [86]

Answer:

Sin156

Step-by-step explanation:

Given

Sin24

Required

Find equivalent between 0 to 180;

Let 24 be represented by \theta

So, \theta = 24

From Trigonometry ratios;

Sin\theta = Sin(180 - \theta) where 0\leq \theta \leq 180

Recall that \theta = 24

So, we have to substitute 24 for \theta in the above expression.

This gives

Sin24= Sin(180 - 24)

Subtract 24 from 180

Sin24= Sin156

Hence, the equivalent of Sin24 is Sin156

20 business cards are placed in a hat, 10 belong to women, 10 belong yo men If 2 cards are drawn at once. what's the probability
erik [133]

Answer:

First choice:

               \large\boxed{\large\boxed{5/19}}

Explanation:

<em>The probability that the first is a man's card and the second, a woman's card</em> is calculated as the product of both probabilities, taking into account the fact that the second time the number of cards  in the hat has changed.

In spite of it is said that the cards are drawn at once, since it is stated a specific order for the cards (first is a man's card and the second, a woman's card) you can model the procedure as if the cards were drawn consecutively, instead of at once.

<u>1. Probability that the first is a man's card</u>

  • Number of cards in the hat = 20 (the 20 business card)

  • Number of man's card in the hat: 10

  • Probability = favorable oucomes / possible outcomes = 10/20 = 1/2.

<u />

<u>2. Probability that the second is a woman's card</u>

  • Number of cards in the hat = 19 (there is one less card in the hat)

  • Number of wonan's card in the hat: 10

  • Probability = favorable oucomes / possible outcomes = 10/19.

<u>3. Probability that the first is a man's card and the second, a woman's card</u>

<u />

  • (1/2) × (10/19) = 5/19

That is the first choice.
