We should find the area of the carpet squares. Since each side is 1 foot, the area will be 1. Now, Julie used 120 carpet squares, which is 1 in area. So, we will have to multiply 1 by 120.
120×1=120
The area of the floor is 120 ft².
Answer:
C.Yes, because the joint probability of P and M is equal to 0.
Step-by-step explanation:
If M and P are two sample spaces of their respective events, such that ( A ∩ B ) = Ø [phi or the empty set represented by ‘Ø’ contains no element]. Then the probability of either A or B happening will be written as follows:
P ( M ∪ P) = P (M) + P ( P ) ; where the symbol ‘∪’ represents union or the word ‘or’. So the probability of occurrence of either A or B when A and B are mutually exclusive events is equal to the probability of occurrence of A plus the probability of occurrence of B.
Answer:
Answer ? = 9
Step-by-step explanation:
the commutative property of addition just means that when adding (say counting numbers) you can reverse the order. It won't matter how you do the addition. For example
5 + 9 = 9 + 5
Some number systems don't like that very much. So the number you put in for the question mark is 9.

Step-by-step explanation:
The vector appears as shown in the attached illustration. This is tantamount to finding the ? side of the right-angled triangle. The formulae is;
a² + b² = c²
24² + x² = 30²
x² = 30² – 24²
= 900 - 576
x² = 324
x = 18
