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
Answer:
6x-15
Step-by-step explanation:
-1/2*2(-6x+15)
-(-6x+15)
6x-15
Answer:
This cannot be explained properly by me, but the answer is 4 3/4*1 1/3 divided by (7 1/2-1 1/6). I just did a lot of trial and error
Step-by-step explanation:
The mathematical form of given statement is 3/x³.
The given statement is "The quotient of 3 and the cube of a number."
We have to write the mathematical form of a given statement.
A mathematical statement is a meaningful component of words that can be true or false. Simply, they are known as a statement.
Let us assume the number be x.
Here, the quotient means division.
The given statement says that quotient of 3 and cube of number that means 3 is divisible by x³.
So, we get 3/x³.
Hence, the mathematical form of given statement "The quotient of 3 and the cube of a number" is 3/x³.
