Among the 2,598,960 possible five card poker hands from a standard 52 card deck, how many contain at least one spade?

1 answer:

8 0

All you need to do is find the probability of getting 0 spades for 5 cards in a row, subtract from 1, and multiply by 2,598,960.

I'll even do the first part: P(0 spades) =
(39/52)*(38/51)*(37/50)*(36/49)*(35/48)

The length of each side of a regular pentagon is increased by 8 inches, so the perimeter is now 65 inches. What is the original

evablogger [386]

Here as the Pentagon is regular so it's all sides will be of equal length . And if we assume It's each side be s , then it's perimeter is going to be (s+s+s+s+s) = 5s.And as here , each side is increased by 8 inches and then it's perimeter is 65 inches , so we got that it's side after increament is (s+8) inches and original length is s inches . And if it's each side is (s+8) inches , so it's perimeter will be 5(s+8) and as it's equal to 65 inches . So , 5(s+8) = 65

${:\implies \quad \sf 5(s+8)=65}$

${:\implies \quad \sf 5s+5\times 8=65}$

${:\implies \quad \sf 5s+40=65}$

${:\implies \quad \sf 5s=65-40}$

${:\implies \quad \sf 5s=25}$

${:\implies \quad \sf s=\dfrac{25}{5}=5}$

${:\implies \quad \bf \therefore \quad \underline{\underline{s=5\:\: Inches}}}$

As we assumed the original side to be s .

Hence, the original side's length 5 inches

Write an equation for each condition listed.

Svetlanka [38]

Look for the y-intercept
since we know the slope is 3 we just going to plug in
-5=3(1)+y
-5-3=y
so the y-intercept is 8 now you can find the equation
y=3x-8

a game cost $30 and a stoe bought it and sold it for $50. what is the percent makeup???????????????? need help ASAP!

PIT_PIT [208]

Answer:

67%

Step-by-step explanation:

Cost plus markup = selling price.

Here, the cost was $30 and the selling price was $50. Subtracting $30 from $50, we get $20, which was the dollar amount of the markup.

We now compare this $20 to the original cost ($30):

$20

------- * 100^ = 67%

$30

The markup, as a percentage, was 67%.
