Answer:

7/13

Step-by-step explanation:

There are a total of <em>13</em> spades and <em>13</em> clubs for a total of<em> 26 </em>black cards.

There are also <em>four</em> 8's, but <em>two</em> of them are black.

Pblack= <em>26/ 52 </em>

P8 = 4/52- 2/52= <em>2/52</em>

Now you would add the two probabilities:

P= 26/52 + 2/52= 28/52= 7/13

I WILL GIVE BRAINLIEST Given: BFCE, AB perpendicular to BE, DE perpendicular to BE,
mars1129 [50]

Answer:

Step-by-step explanation:

From the given picture,

∠ABE = ∠DEF = 90° [Since, AB and DE are perpendicular to DE]

m∠ECA = m∠BFD [Given]

m∠ECA + m∠ACB = 180° [Liner pair of angles]

m∠BFD + m∠DFE = 180° [Liner pair of angles]

m∠ACB + m∠ECA = m∠BFD + m∠DFE [Transitive property]

m∠ACB = m∠DEF [Since, m∠ECA = m∠BFD]

Therefore, ΔABC ≅ ΔDEF [By AA property of similarity]

The World Equity Index function shown contains two valuation metrics for the S&amp;P 500. The Verizon description page contains
Nikitich [7]

Answer: Verizon is less expensive than the S&P 500 on both a P/E and dividend yield basis.

Step-by-step explanation:

When a <em>Price to Earnings ratio is relatively high</em> this means that the <em>Price of the security is high </em>because investors believe the company has good prospects.

When a Dividend Yield is relatively low, this means that the dividends being declared are quite lower than the price because Dividend yield is dividends as a percentage of security price. <em>Lower Dividend Yields therefore mean high security prices</em>.

Looking at the Verizon Chart and the S&P 500 you see that Verizon P/E ratio is 11.71 while S&P is 19.01.

This means that the price of Verizon's is less than S&P 500.

Also notice that Verizon's Dividend yield is 4.09% while S&P 500's is 1.91% again signifying that Verizon is cheaper.

I have attached the full question.
