Answer:
8.41
Step-by-step explanation:
i think
parallel = same slope
y=1/5x-4
slope= 1/5x
solve using for b using y=mx+b
-4=(1/5)(5)+b
-4=4+b
(subtract -4 from both sides)
-8=b
put your equation together:
y=1/5x-8
Answer is 1/36...
probability of rolling a 3 is 1/6 so if you do it twice it will be 1/6×1/6=1/36
Answer:
x=4
Step-by-step explanation:
5x + 33 = 18x-30 + 11
Add the numbers
5x + 33 = 18x-19
Subtract 33 from both sides of the equation
5x + 33-33 = 18x-19-33
5x=18x-52
Subtract 18x from both sides of the equation
5x-18x = 18x-52-18x
-13x = -52
-13x/-13 = -52/-13
x=4
Answer:
41/293
Step-by-step explanation:
You have to be a little careful with the denominator. It must be the total of the columns which is the same total for the rows -- 586
The numerator is just the intersection of rats and Ravenclaw which is 82
So the answer is 82/586
The answer is also 41 / 293
In case you want the decimal it is .1399 rounded.
