from the Deck of 52 cards is drawn at a random . what is the probability of a face card or ace ?​

Answers

Step-by-step explanation:

Given that,

Total no. of cards = 52 (Total no. of outcomes)

There are 12 face cards. No of favorable outcomes = 12

P(E) = favorable outcome/total no of outcomes

So,

[tex]P(F)=\dfrac{12}{52}\\\\=\dfrac{3}{13}[/tex]

There is 4 ace in a deck of 52 cards.

[tex]P(A)=\dfrac{4}{52}\\\\=\dfrac{1}{13}[/tex]

Hence, this is the required solution.

Group of answer choices demanded; the price of the good supplied; the price of the good demanded; the price of another good supplied; the price of another good demanded; income

Answers

Answer:

Answer:

Remark

This is one of those things that when you see it, you think that really is something.

The trick is to subtract a smaller right triangle from a larger one.

The base for both triangles is 4 (going from where the right angle is to your right where the lines of the red enclosure meet.

Calculations

The height of the larger triangle is 8

The height of the smaller triangle is 5

Ava has $300 on her credit card. She bought a laptop for $215, and decided to spend the rest on shirts. The unit price of shirts which are on sale is $15. Part A: Enter an inequality which represents the maximum number of shirts, s, Ava can buy. Part B: What is the maximum number of shirts Ava can buy?

Answers

Answer:

s≤5

Step-by-step explanation:

Given data

Amount on credit card= $300

Cost of Laptop= $215

Change = 300-215

              =$85

We are told that the unit cost of shirts is $15

Hence the number of shirts $85 can buy is

=85/15

=5.6 shirts

Step-by-step explanation:

In order to solve this square pyramid's volume, we use the formula:

V = 1/3(B)(h)

Now, we plug in what we know. Since it has a square base, the sides of the base are all the same:

1/3(10*10)(12)

Now we solve:

Answer:

  (a) 38.3 m horizontal distance

  (b) 82.1 m high

Step-by-step explanation:

I like a graphical solution to this problem (attached).

__

If you define h as the horizontal distance to the tower, and t as its height, you can write two equations. Since these sides are adjacent and opposite the given angles, the tangent relationship is useful.

  tan(65°) = t/h

  tan(40°) = (t -50)/h

__

Multiplying both equations by h and substituting for t, we have ...

  h·tan(40°) = h·tan(65°) -50

  h = 50/(tan(65°) -tan(40°)) . . . . solve for h

  h ≈ 38.3022

Then the tower height is ...

  t = h·tan(65°) ≈ 82.1394

The tower is about 38.3 m distant and 82.1 m high.
