"Suppose you draw a single card from a standard deck of 52 cards. How many ways arethere to draw either queen or a heart?"

16 ways

Step-by-step explanation:

We are given that

Total cards=52

Total queen in deck of cards=4

Total cards of heart=13

We know 1 card of queen is heart

Number of ways drawing one card of heart out of 13=

Using combination formula ;

Number of ways drawing one card of heart out of 13=

Number of ways of drawing one card of queen out of 4=

Number of ways of drawing one card of queen out of 4=

Total number of ways of drawing one card out of 52 cards=

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
