Step-by-step explanation:
From. The plot, we can conclude that, the detergent that has the most bottles is that with 5 ; the number of cups in the detergent with 5 bottles is 12 cups
Number of cups used for each load of laundry = 18 cups
The loads of laundry Eric can do is thus :
Number of cups of detergent / number of cups used for each load of laundry
= 12 / 18
= 2 / 3 loads

Answer:
The value of given expression is
.
Step-by-step explanation:
Given information: n=7, x=2, p=1/2
![q=1-p=1-\frac{1}{2}=\frac{1}{2}](https://tex.z-dn.net/?f=q%3D1-p%3D1-%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B1%7D%7B2%7D)
The given expression is
![C(n,x)p^xq^{n-x}](https://tex.z-dn.net/?f=C%28n%2Cx%29p%5Exq%5E%7Bn-x%7D)
It can be written as
![^nC_xp^xq^{n-x}](https://tex.z-dn.net/?f=%5EnC_xp%5Exq%5E%7Bn-x%7D)
Substitute n=7, x=2, p=1/2 and q=1/2 in the above formula.
![^7C_2(\frac{1}{2})^2(\frac{1}{2})^{7-2}](https://tex.z-dn.net/?f=%5E7C_2%28%5Cfrac%7B1%7D%7B2%7D%29%5E2%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B7-2%7D)
![\frac{7!}{2!(7-2)!}(\frac{1}{2})^2(\frac{1}{2})^{5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%21%7D%7B2%21%287-2%29%21%7D%28%5Cfrac%7B1%7D%7B2%7D%29%5E2%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B5%7D)
![\frac{7!}{2!5!}(\frac{1}{2})^{2+5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%21%7D%7B2%215%21%7D%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B2%2B5%7D)
![\frac{7\times 6\times 5!}{2\times 5!}(\frac{1}{2})^{2+5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Ctimes%206%5Ctimes%205%21%7D%7B2%5Ctimes%205%21%7D%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B2%2B5%7D)
![21(\frac{1}{2})^{7}](https://tex.z-dn.net/?f=21%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B7%7D)
![\frac{21}{128}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B128%7D)
Therefore the value of given expression is
.
