The probability is 25% because the deck is divided into 4 parts which makes it 25% probability of choosing a club or a heart.

Suppose A and B represent two different schools populations where A>B abd A and B must be greater than 0. Which of the follow

igor_vitrenko [27]

Hmm, one way we can do this is by assigning numbers to each

A=4 and B=3
A>B because 4>3

so

A. 2(A+B)=2(4+3)=2(7)=14
B. A+B^2=4+3^2=4+9=13
C. A^2+B^2=4^2+3^2=16+9=25
D. A^2-B^2=4^2-3^2=16-9=7

the largest is 25 so C

What is the value of 2 over 3 to the power of 0 to the power of -3

Schach [20]

Answer:

$((\frac{2}{3})^0)^{-3}=1$

Step-by-step explanation:

We need to find the value of $((\frac{2}{3})^0)^{-3}$

Solving:

We know, $(a^b)^n = a^{b*n}$

$((\frac{2}{3})^{0*-3})$

$(\frac{2}{3})^0$

a^0 = 1

so,

$(\frac{2}{3})^0=1$

So, the value of $((\frac{2}{3})^0)^{-3}=1$

Trina has 72 collector’s stamps. She puts 43 of the stamps into a stamp book. How many stamps are left?

sattari [20]

Hi! For this question all you have to do is subtract 43 from 72.

72 - 43 = 29

Trina had 29 stamps left.

Hope this helps! Happy Thanksgiving!
