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)

What annual rate of interest would you have to earn on an investment of $3500 to ensure receiving $273.00 interest after 1 year?

kogti [31]

To find the answer, we will have to find the percentage of $273 to $ 3500, and we can use the formula:

$\frac{interest received}{investment amount} \times 100%$

In this case:

273/3500 x 100%

=39/500 x 100%

=7.8%

Therefore the annual interest rate would be 7.8%.

Hope it helps!

kykrilka [37]

Answer:

16x² + 64x + 64

Step-by-step explanation:

Given

A = 16x²

Increasing the sides by 2, substitute x = x + 2 into A

A = 16(x + 2)² ← expand factor using FOIL

= 16(x² + 4x + 4 ) ← distribute

= 16x² + 64x + 64
