Answer: 12
Step-by-step explanation:
difference = subtraction
and = addition
times = multiplication
Therefore,
7x - 4 = 80
7x = 84
x = 12
Answer:
The answer is .
Step-by-step explanation:
Solve the inequality:
-Divide both sides by 3:
So, the answer is
Answer:
The probability of getting an odd number when the spinner is spun, is p(even number) = 1/2
Step-by-step explanation:
Given that the spinner has 12 equal sections labelled 1-12
Let S be the sample space
Then
S = {1,2,3,4,5,6,7,8,9,10,11,12}
Let A be the event that the outcome is an even number
Then
A = {2,4,6,8,10,12}
The probability of A will be given as:
Hence,
The probability of getting an odd number when the spinner is spun, is p(even number) = 1/2
