one of those answers.
Hope this helps and GOOD LUCK :)
I think it is 20 because you have to multiply and then divide them add 11 then subtract 9 idk what I am saying
Answer:
4
Step-by-step explanation:
The radius of the circle times 2 to make it the diameter, because the diameter of the circle is the same as the side length.
Answer:
The minimum weight of the heaviest 9.85% of all items produced is 5.26 ounces.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
![\mu = 5, \sigma = 0.2](https://tex.z-dn.net/?f=%5Cmu%20%3D%205%2C%20%5Csigma%20%3D%200.2)
What is the minimum weight of the heaviest 9.85% of all items produced?
This is the 100 - 9.85 = 90.15th percentile, which is X when Z has a pvalue of 0.9015. So X when Z = 1.29.
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![1.29 = \frac{X - 5}{0.2}](https://tex.z-dn.net/?f=1.29%20%3D%20%5Cfrac%7BX%20-%205%7D%7B0.2%7D)
![X - 5 = 1.29*0.2](https://tex.z-dn.net/?f=X%20-%205%20%3D%201.29%2A0.2)
![X = 5.26](https://tex.z-dn.net/?f=X%20%3D%205.26)
The minimum weight of the heaviest 9.85% of all items produced is 5.26 ounces.

Answer:
Step-by-step explanation:
From the question we are told that
The relationship is ![\frac{150 }{d} = \frac{130}{c}](https://tex.z-dn.net/?f=%5Cfrac%7B150%20%7D%7Bd%7D%20%20%20%3D%20%5Cfrac%7B130%7D%7Bc%7D)
The number of fence post painted by chuck is
The number of fence post painted by Diana is ![k = 150](https://tex.z-dn.net/?f=k%20%3D%20%20150)
can paint 10 fences more than chuck so let say the of fence painted in an hour by chuck is ![g](https://tex.z-dn.net/?f=g)
Then the number of fence post painted by Diana in one hour is
![f = g+ 10](https://tex.z-dn.net/?f=f%20%3D%20%20g%2B%2010)
So
![\frac{150 }{ g + 10 } = \frac{130}{g}](https://tex.z-dn.net/?f=%5Cfrac%7B150%20%7D%7B%20g%20%2B%2010%20%7D%20%20%20%3D%20%5Cfrac%7B130%7D%7Bg%7D)
![130 g + 1300 = 150g](https://tex.z-dn.net/?f=130%20g%20%20%2B%201300%20%3D%20%20150g)
![g = 65 \ m](https://tex.z-dn.net/?f=g%20%3D%20%2065%20%5C%20%20m)
