If the mean is 8 with a standard deviation of 1.5, the percentile rank of a shoe with at least a size of 9 is 66.6 repeating, or 67th if rounded.
Answer:
Solutions:-5,0,9,6
Not solutions: 12.5,10
Explanation:
The inequality that was given is:
20 > 5 + 3x
First, group similar terms;
20 - 5 < 3x
15 < 3x
x = 5
Thus, the solutions are:-3.5, 5, 4 3/4, -15
The not solutions are:-10 2/3, 129,
Hope this helps! :)
Answer:
Step-by-step explanation:
It is blurry sorry man
The diagnonals of a parallelogram bisect each other ,
so
=》 BD = 3x × 2
=》BD = 6x
and there's given that
=》
![BD = \dfrac{3}{5} AC](https://tex.z-dn.net/?f=%20BD%20%3D%20%5Cdfrac%7B3%7D%7B5%7D%20AC)
=》
![6x = \dfrac{3}{5} \times 40](https://tex.z-dn.net/?f=6x%20%3D%20%20%5Cdfrac%7B3%7D%7B5%7D%20%20%5Ctimes%2040)
=》
![x = \dfrac{24}{6}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cdfrac%7B24%7D%7B6%7D%20)
=》
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
so, if x = 4 , then the given quadrilateral is a parallelogram.
6(x+1)=24
6x+6=24
6x=24-6
6x=18
6x/6=18/6
x=3
