Answer: x = 2/7
Step-by-step explanation: Hope this helps :)
Answer: x = 0 and x = 7
Step-by-step explanation:
9x^2 - 63x = 0.
We can factor out 9x from both terms on the left side:
9x(x - 7) = 0.
To be equal to 0, one of the terms has to be 0.
Therefore, either 9x = 0 or x - 7 = 0.
First, we solve the case where 9x = 0.
Then, x = 0.
Second, we solve the case where x - 7 = 0.
We add 7 to both sides:
So, x = 7

Step-by-step explanation:
Given the data below :
x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6
Mean(m) = ΣX / n
ΣX = 1066 ; n = number of observations = 18
Mean(m) = 1066 / 18
Mean = 59.22
Standard deviation (σ) :
Using the online standard deviation calculator :
σ = √(Σ(x - m)²/n-1)
σ = √264.198395
σ = 16.72
The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.
typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.
(59.22 - 19.7) mL = 39.52mL
Mean amount poured into a tall slender glass = 51.283
Mean (short wide glass) = 59.22mL
Mean (tall slender glass) = 51.283mL
Short wide glass > tall slender glass
