Lacy draws a diamond from a standard deck of 52 cards. Without replacing the first card, she then proceeds to draw a second card
Viktor [21]

Answer:

a) i) No

ii) Probability of drawing a diamond and then spade without replacement is 0.0637.

b) i) Yes

ii) Probability of drawing a diamond and then spade with replacement is 0.0625

Step-by-step explanation:

Part a) Without replacement:

i) Are these events independent?

No, because the both events are dependent. because a card taken out of the deck is not replaced back before taking out the other card so the chances of event occur change.

ii) Determine the probability of drawing a diamond and then a spade without replacement.

Probability of drawing a diamond and then spade = (Probability of drawing a diamond) * (Probability of drawing a spade)

Probability of drawing a diamond :

Total cards in deck = 52

Diamonds = 13

Probability of drawing a diamond  = 13/52

Probability of drawing a spade:

Total cards in deck after taking diamond = 52 -1 =51

Spades = 13

Probability of drawing a spade  = 13/51

Probability of drawing a diamond and then spade = 13/52 * 13/51

= 169/2652

=0.0637

So, Probability of drawing a diamond and then spade without replacement  is 0.0637

Part b) With replacements

i) Are these events independent?

Input Yes or No:

Yes, these events are independent because a card taken out of the deck is replaced back before taking out the other card so the chances of event occur doesn't change.

ii) Determine the probability of drawing a diamond and then a spade with replacement.

Probability of drawing a diamond and then spade = (Probability of drawing a diamond) * (Probability of drawing a spade)

Probability of drawing a diamond :

Total cards in deck = 52

Diamonds = 13

Probability of drawing a diamond  = 13/52

Probability of drawing a spade:

Total cards in deck after replacing diamond = 52

Spades = 13

Probability of drawing a spade  = 13/52

Probability of drawing a diamond and then spade = 13/52 * 13/52

= 169/2704

=0.0625

So, Probability of drawing a diamond and then spade with replacement is 0.0625

A six feet-tall person is standing next to a flag pole.The person is casting a shadow 1 1/2 feet in length,while the flagpoleis
Vlad1618 [11]

Answer:

20 feet

Step-by-step explanation:

Consider the given pictorial representation below,

The Height of the Pole =|AB|

The Height of the Person =|DE|

Shadow cast by the Pole =|AC|

Shadow cast by the Person =|EC|

Triangles ABC and DEC are similar triangles therefore,

\frac{|DE|}{|AB|} =\frac{|EC|}{|AC|}

\frac{6}{x} =\frac{1.5}{5}

Cross multiplying

x X 1.5 = 6 X 5

x=30/1.5 =20 feet

Height of the flag pole = 20 feet

Hi! Please help me im really confused &gt;.&lt; tysm<br> g² - 4g = -3
Sholpan [36]

Answer:

g = 1, 3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Terms/Coefficients
  • Factoring
  • Solving quadratics

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

g² - 4g = -3

<u>Step 2: Solve for </u><em><u>g</u></em>

  1. [Addition Property of Equality] Add 3 on both sides:                                     g² - 4g + 3 = 0
  2. Factor:                                                                                                                (g - 1)(g - 3) = 0
  3. Solve:                                                                                                                 g = 1, 3
