Answer:
Step-by-step explanation:
First, we need to add all the jellybeans together to find the chances of a specific bean per type out of all of them.
42 + 45 + 20 + 32 = 139 beans
So now we have to decide individually the probabilities of the two types
The probability of getting a purple bean is equal to
32/139 and the probability of NOT getting a red bean is equal to
97/139
So now you just add them together:
32 + 97 = 129/139
And the percentage of that would be approximately 92.81%
Knowing that the line is parallel to another one with equation y = -2x+3, we know that the slope of this line (m) is -2. Plugging this into the point-slope equation
(y-b=m(x-a)), we get y+3=-2(x+4) as our answer.
Step-by-step explanation:
y=mx-c
m=gradient
L1: y=3x-2
gradient: 3
L2:
3y-9x+5=0
3y=9x-5
y=3x-5/3
Gradient:3
when gradients of 2 lines are equal, the lines are parallel
