(c) Find the number of sets where all three cards are the same for exactly $0$ attributes. (d) Find the number of sets where all
Cloud [144]

C. For the first card, there are three ways to choose the number of card.

For the another, there two options, and likewise there's only 1 choice of card. So there are 3 × 2 × 1 = 6 ways that the calculation can be chosen.

Doing this for the other attributes, we get 6 × 6 × 24 × 6 ways. But the order of cards does not count in a set of card, so we divide by 3! 6 * 6 * 24 × 6 ÷ 3! = 864. It means there are 864 sets for part.

D. The cards may have the same number, color, shapess, orshading.

However, also there are 6 × 24 × 6 × 3! = 144 sets of cards, If all the colors are thesame. How ever, also there are 144 sets of cards.

If all the calculation are the same. We get the same number for shape and shadings, so there are 4 × 144 = 576 sets of cards.

The Garzas plan to invest $2,000 for 5 years. What annual simple interest rate must the investment earn in order for the Garzas
insens350 [35]

Answer:

r=20%

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=5\ years\\ P=\$2,000\\ A=\$4,000\\r=?

substitute in the formula above

4,000=2,000(1+5r)

solve for r

2=(1+5r)

5r=2-1\\5r=1\\r=\frac{1}{5}=0.20=20\%
