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.
Answer:your answer is x/8=15
I got it wrong and it showed this one is right
53-5=--19z+7z
48= --12z
divide both side by -12
Z= -4
The triangles are similar in that the smaller triangle was dilated by a scale factor of 1/4 which means that the length of the missing side is 20m
