Since it is not mentioned in the problem, we will assume that repeating of number is allowed.
For the first wheel, you have 10 possible digits.
For the second wheel, you have 10 possible digits.
For the third wheel, you have 10 possible digits.
10 x 10 x 10 = 1000
The probability that someone randomly guesses the correct combination in his first attempt is 1/1000.
If this was without repeat, then
10*9*8 = 720
The probability that someone randomly guesses the correct combination in his first attempt is 1/720.
Answer:
Divide
Step-by-step explanation:
If you mean as in, what percent of 28 is 17, you can just divide 17/28. It would be 61% or 61/100 as a fraction! (unless you mean something else :c )
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
Given
y = 
x - 2
Multiply through by 9
9y = x - 18 ( add 18 to both sides )
x = 9y + 18
Change y back into terms of x, hence
(x) = 9x + 18
Answer: 58 1/3 yards
Step-by-step explanation:
From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.
The number of yards that they have to get on their next play to get a first down would be calculated as:
= 30 - -28 1/3
Note that minus × minus = plus
= 30 + 28 1/3
= 58 1/3 yards
