Answer:
First find the area 72*63
A=4536
Then find the area 12*12
A=144
Then divide 4536/144
You would need 31.5 12 by 12in covers to decorate the rectangular region
As for the 6 by 6
You would need 126 album covers
As for the 9 by 9
You would need 51 covers
And as for the 15 by 15
You would need 20.6 covers
12 inches or 1 foot because 24/3=8 and 8*1.5=12
The probability of first number cube shows a five and the other number cube shows an even number is
.
Solution:
Two cubes are rolled sequentially.
Sample space when two dies are rolled

Number of sample space = 36
Even numbers getting when two cubes rolled are 2, 4, 6.
First number cube shows a five and the other number cube shows an even number = {(5, 2), (5, 4), (5 6)}
Number of first number cube shows a five and the other number cube shows an even number = 3
Probability of first number cube shows a five and the other number cube shows an even number



Hence, the probability of first number cube shows a five and the other number cube shows an even number is
.
#1 is C, #2 is B, #3 is C, and #4 is A.
There’s no inverse for this function but d/dx is (1/((x+(pi/2))^2 +1)
