The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12.
It's graph C. because on the first pair of numbers you can see that they both line up with the graph. Also, if you find the pattern between the numbers (x-3 and y-1) the graph C. lines up.
Hoped I helped! :)
Answer:
Fraction = 5/10 = 1/2
Decimal = 0.5
Step-by-step explanation:
To solve this we'll put the question in this format: x% of y things = z things
We have the percent so we'll put in 60 for x.
Now the total number of balls will be considered y since we have the number of red balls but not blue ones. so we end up having..
60% of y balls = 720 balls
Of is another word for multiplication, therefore:
60/100*y=720
Solve for y
y=1200
So we have 1200 balls
Answer:
x= 7, the number is 7
Step-by-step explanation:
4x-9= 19
4x=28
