The angle is 18 more than its supplement. Find the angle.

Lynna [10]

Answer:

81 , 99

Step-by-step explanation:

Let the supplement angle = x

The required angle = x+ 18

x + 18 + x = 180 {Supplementary}

2x + 18 = 180

Subtract 18 form both sides

2x = 180- 18

2x = 162

Divide both sides by 2

x = 162/2

x = 81

x + 18 = 81 + 18 = 99

The probability that Terri will draw a heart and then a red face card from a standard 52-card deck is . Using this probability,

Anestetic [448]

<h3>The both events are <u>not independent</u> as the intersection of outcomes of both the events is 3 and not equal to Ф.</h3>

Step-by-step explanation:

Here, the total number of cards in a deck = 52

The total number of heart cards = 13

The total number of red faces in the deck = 6 ( 3 of heart and 3 of diamonds)

Now, out of the TOTAL 6 red face cards, 3 are of hearts.

So, (Red cards) ∩ (Heart cards) = 3 cards ( J, Q and K)

Now let E : Event of picking card which is of heart.

$P(E) = \frac{\textrm{Total number of red hearts}}{\textrm{Total cards}} = \frac{13}{52} = (\frac{1}{4})$

So, the probability of picking a heart = $\frac{1}{4}$

Now let F : Event of picking card which is of red face.

$P(E) = \frac{\textrm{Total number of red faces}}{\textrm{Total cards}} = \frac{6}{52} = (\frac{3}{26})$

So, the probability of picking a red face card = $\frac{3}{26}$

Hence, the both events E and F are <u>not independent</u> as the intersection of outcomes of both the events is 3 and not equal to $\phi$ .
