Answer:
Step-by-step explanation:
we have to get y by itself here i think
so
x + 2y = 12
2y = -x + 12
y = -1/2 + 6
7x + 2y = 0
2y = -7x
y = -3.5x
hope this helps <3
Answer:
9.17 feet
Step-by-step explanation:
Use the Pythogoras theorem, a^2 + b^2 = c^2
you are give c and b ( because one side is slanted, so c) so rearrange to get
c^2-b^2 = a^2
10^2 - 4^2 = 84
square root 84 to get
9.16515
Answer:
The percentage of volumes that are within 3 standard deviation of the mean is 99.73%.
Step-by-step explanation:
We want to calculate the area under the curve within 3 standard deviations from the mean.
If we use the standard normal distribution, this probability can be calculated as the diference between P(z<3) and P(z<-3).
The area under the curve for the standard distribution and for any normal distribution within 3 standard deviation from the mean is 0.9973.
The percentage of volumes that are within 3 standard deviation of the mean is 99.73%.
