Answer:
the answer is 54
Step-by-step explanation:
48 / 4 is 12, so then divide that by 2 so they split equally because theirs combined added to 48, so 6.
6 * 9 is 54
Answer:
(B)25
Step-by-step explanation:
From the given diagram:
are on a straight line, and we know by the Linear Postulate that the sum of angles on a straight line is 180 degrees.
Therefore:
The correct option is B.
Answer:
Exact probability = 1/7
(Approximate probability = 0.142857)
========================================================
Explanation:
There are three 5 dollar bills out of 7 total. The probability of selecting a five dollar bill is 3/7. Let A = 3/7 since we'll use it later.
After the first selection is made, we have 3-1 = 2 five dollar bills left out of 7-1 = 6 bills overall. This is assuming we do not put the first selection back, or replace it with another five dollar bill.
The probability of selecting another five dollar bill is 2/6 = 1/3. Let B = 1/3.
Multiply the values of A and B to get
A*B = (3/7)*(1/3) = (3*1)/(7*3)= 1/7
Note the 3's divide and cancel out.
Using a calculator, 1/7 = 0.142857 approximately
It’s an expression that compares two or more numbers. Ex; 3:10.
