There is a 1/3 chance that a red marble would be chosen.
To find out you put add up the marbles, so they will make 12 marbles.
Since there are 4 red you put 4/12.
4/12 simplified is 1/3.
So the chance of a red marble being picked is 1/3.
Answer:
Step-by-step explanation:
This is an arithmetic series.
3 , 5 , 7 ,......
Common difference = second term - first term
= 5 - 3
= 2
Answer:
y= 1/2x-3
Step-by-step explanation:
2y - x = 8
First find the slope
2y = x+8
Divide by 2
2y/2 = x/2 +8/2
y = 1/2 x +4
The slope is 1/2 ( y=mx+b where m is the slope and b is the y intercept)
When lines are parallel they have the same slope)
Using y = mx+b
y =1/2x+b
Substituting the point (4,-1) into the equation
-1 =1/2(4)+b
-1 = 2+b
-3 =b
The equation of the line is
y= 1/2x-3
to be honest I agree that would be 6s
Answer: 5
Step-by-step explanation: Let's go over a little algebra terminology.
The number in front of your variable is called your coefficient and a variable is just a letter that represents any number.
So here, your coefficient is 5 since it appears in front of the variable, x.
