x
Step-by-step explanation:
Answer:
Step-by-step explanation:
Question 1:
First, write the equation out:
4(x+3)=7x-3
solve for x:
4x+12=7x-3
15=3x
x=5
Question 2:
Do the same on the second question:
30-x=3x-6
36=4x
x=9
Answer:
true
Step-by-step explanation:
it is good to go back to the equation because maybe you placed a number wrongly or you did not understood the problem correctly
Answer:
A = 9x² + 48x + 65
Step-by-step explanation:
Area of a Square Formula: A = lw
Since a square's length is equal to its width, we simply plug it into the formula:
A = (3x + 8)(3x + 8)
Then we simply use FOIL to expand the distribution)
First - 3x(3x) = 9x²
Outside - 8(3x) = 24x
Inside - 8(3x) = 24x
Last - 8(8) = 64
Lastly, we combine like terms
9x² + 24x + 24x + 64
9x² + 48x + 64
Answer:
Option B) In control as this one data point is not more than three standard deviations from the mean
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 104 rotations per minute
Standard Deviation, σ = 8.2 rotations per
We are given that the distribution of process is a bell shaped distribution that is a normal distribution.
Formula:

For x = 118

Thus, we could say that this data point lies within three standard deviations from the mean as:

Thus, it could be said
Option B) In control as this one data point is not more than three standard deviations from the mean
