Answer:

a) The probability that a card drawn is a heart is 1 out of 4.

b) The probability that a card drawn is a face card is 3 out of 13.

c) The probability that a card drawn is either a face or a heart card is 11 out of 26.

Step-by-step explanation:

a) This question asks your ability to examine that from the total number of cards, what is the random probability that you'll pull out a heart card. That should be 13/52, and simplified, it is 1/4.

b) This question asks your ability, like in a), to examine the probability of pulling a face card out of all the cards, which is 12/52 or 3/14.

c) From all the cards, 13 are hearts and 12 are face cards. But of the 12 face cards, 3 are hearts, so we only have 9, giving us 22/52, simplify it, you get 11 out of 26.

In angle PQR, angle P = (4x – 14)º, angle Q = (5x + 6)", and angle R= (x - 2)°. Find<br> angle R.
vekshin1

we have: ∠P + ∠Q + ∠R = 180°

<=> (4x – 14)º + (5x + 6)° + (x - 2)° = 180°

<=> 4x – 14 + 5x + 6 + x - 2 = 180°

<=> 10x - 10 = 180°

<=> 10x = 190

<=> x = 19°

So: ∠R = (x - 2)° = (19 - 2)° = 17°

ok done. Thank to me :>

A batch of snack mix made of dried fruit and nuts contain 744G of nuts the ratio of nuts to dried fruit by weight is 12 to 13 ho
Bezzdna [24]

In a bag of snack mix:

n = nuts       d = dried fruit

n = 744g        d = ???g

Ratio Nuts/Dried fruit = 12/13

This basically means that if the mix was divided in 25 parts, 12 parts would be nuts and 13 would be dried fruits

If 744 is 12 parts then 744/12 is 1 part

744/12 = 62

1 part = 62g

there are 13 parts of dried fruit

13 x 62 = 806

744g of nuts + 806g of dreid fruit = 1550g

Answer: A batch of snack mix weigh 1550g, or 1.55kg

hope it helps :)

Dima020 [189]
Rst you have to find the price of everything together

2 magazines for 9.95 each and a book for 14.95

9.95 + 9.95 + 14.95 = 34.85

Next you convert the percent to a decimal

6% = 0.06

Now you put a one in the ones place

1.06

34.85 * 1.06 = 36.94

The answer is $36.94

Hope this helps!
