Answer: Third quartile =$21.58
Step-by-step explanation:
Let x be value of a stock .
For uniform distribution,
probability density function = 
Let a be the stock value such that P(x<a) =75% or 0.75
![\Rightarrow\ \int ^{a}_{10.82}f(x)\ dx=0.75\\\\\Rightarrow\ \int ^{a}_{10.82}\dfrac{100}{1435}\ dx=0.75\\\\\Rightarrow\dfrac{100}{1435}[x]^{a}_{10.82}=0.75\\\\\Rightarrow \dfrac{100}{1435}(a-10.82)=0.75\\\\\Rightarrow a-10.82=0.75\times\dfrac{1435}{100}\\\\\Rightarrow a-10.82=10.7625\\\\\Rightarrow a= 10.7625+10.82= $$21.5825\approx $$21.58](https://tex.z-dn.net/?f=%5CRightarrow%5C%20%5Cint%20%5E%7Ba%7D_%7B10.82%7Df%28x%29%5C%20dx%3D0.75%5C%5C%5C%5C%5CRightarrow%5C%20%5Cint%20%5E%7Ba%7D_%7B10.82%7D%5Cdfrac%7B100%7D%7B1435%7D%5C%20dx%3D0.75%5C%5C%5C%5C%5CRightarrow%5Cdfrac%7B100%7D%7B1435%7D%5Bx%5D%5E%7Ba%7D_%7B10.82%7D%3D0.75%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7B100%7D%7B1435%7D%28a-10.82%29%3D0.75%5C%5C%5C%5C%5CRightarrow%20a-10.82%3D0.75%5Ctimes%5Cdfrac%7B1435%7D%7B100%7D%5C%5C%5C%5C%5CRightarrow%20a-10.82%3D10.7625%5C%5C%5C%5C%5CRightarrow%20a%3D%2010.7625%2B10.82%3D%09%24%2421.5825%5Capprox%09%24%2421.58)
Hence, 75% of all days the stock is below $21.58 or Third quartile =$21.58 .

Step-by-step explanation:
Each digit goes in the place corresponding to its place value.
When no digit has a given place value, a placeholder is used. That is the purpose of zero, a great invention in the history of mathematics. It makes place-value number systems possible.
Answer:
Step-by-step explanation:
Let c represent the minimum number of crafts that Odell must sell at the fair.
Odell spends $55 on supplies to make holiday crafts to sell at a local fair. This means that the total cost of supplying c crafts would be $55
If he decides to sell each craft for $2.50, then the total revenue from selling c crafts would be
2.5c
If he wants to earn more than $130 selling the crafts, the inequality that can be used to determine the minimum number of crafts that Odell must sell at the fair is
2.5c - 55 > 130
Check number.
The check number (7 in the figure) appears on the check twice: once in the upper right corner, and once at the bottom in magnetic ink.
_____
When you order checks, the check numbers in your order are all different. If you use the reorder form supplied, it has information that allows the check printer to make sure new checks start with a sequential number after the last of the old checks.
