Answer:
1/3
Step-by-step explanation:
(5 + 4 + 3 + 3) x 2 = 30
Multiplied by two because two marbles are being picked.
10/30 = 1/3

Answer:
B. 95% confident the average concentration of PCBs in the water supply is between 2.9 ppb and 3.5 ppb
Step-by-step explanation:
You are given the total number of samples, the concentration of lead, and the standard deviation. The standard deviation represents how inaccurate the estimation of the concentration of lead in the drinking water. This means that there can only possibly be a 0.3 ppb error in the estimation. 3.2-0.3=2.9, and 3.2+0.3=3.5
The distance formula is sqare root (x-x)^2+(y-y)^2 and then you will plug in
sqrt(8+13)^2+(4+5)^2
plug that in to your calculator and that will be your answer what ever you get
Answer:
y= -2/3x+3
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts.
y=-2/3x is your original equation
Your slope is still -2/3
y=mx+b
y=-2/3x + b
Substitute the points from the coordinates
5 = -2/3(-3) + b
5 = 2 + b
-2 -2
b=3
Your parallel line equation is: y= -2/3x+3
Have a great day!
