Answer:
The answer on the top is the best line for a line of best fit because...
Step-by-step explanation:
there is a noticeable correlation in the first graph- a positive one. The line of best fit should have about the same amount of line plots on the top than on the bottom. Also, there can be a few line plots that is touching the line of best fit as well. Those line plots will be about the middle of the data and provide a good guideline to make your line of best fit the most accurate. The second graph is pretty scattered and doesn't have a clear correlation therefore having no correlation. Hope this helps!!

Answer:
68 %
Step-by-step explanation:
Let's call X to the random variable ''lengths of a lawn mower part''.
X ~ N(given mean;standard deviation)
X ~ N(4 in;0.2 in)
To find the percentage,first we are going to turn this random variable X into a random variable Z. Z will be a N(0;1)
We do this by subtracting the given mean to the original variable and dividing by it deviation.
P (3.8 in < X < 4.2 in) =
P [(3.8 in - 4 in) / (0.2 in)] < [(X - 4 in)] / (0.2 in) < [(4.2 in - 4 in) / (0.2 in)]
P ( -1 < Z < 1 ) = P (Z < 1) - P (Z< -1)
Where we can find P (Z < 1) and P (Z< -1) in any table of a N(0;1)
P (Z < 1) - P (Z< -1) = 0.8413 - 0.1587 = 0.6826 = 68%
Answer:
It’s D
Step-by-step explanation:
For this case we have the following equation:
Q = Av
Where the area is given by:
A = pi * r ^ 2
A = pi * (d / 2) ^ 2
A = (pi / 4) * d ^ 2
Substituting we have:
Q = ((pi / 4) * d ^ 2) v
From here, we clear the diameter:
d = root ((4 / pi) * (Q / v))
Substituting values we have:
d = root ((4 / pi) * (50/600))
d = 0.36 feet
Answer:
The diameter of a pipe that allows a maximum flow of 50ft ^ 3 / min of water flowing at a velocity of 600ft / min is:
d = 0.36 feet
