Answer:
The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level
Step-by-step explanation:
Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.
Sample proportion 
(Two tailed test at 5% significance level)
p difference = 
Std error if H0 is true = 
Test statistic Z = p diff/std error
=0.539
p value = 0.5899
Since p > 0.05 accept null hypothesis
The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

Answer: $10.20
Step-by-step explanation:
Let's first collect the information from the word problem.
<h3><em>We are told:</em></h3>
- Bought 15 pies and 7 cake slices
- Total cost was $55.22.
- Pies cost
as much as a slice of cake
<h3><em>We need to solve for:</em></h3>
- Total cost of 1 pie and 2 cake slices
1. Create an equation/expression:
To solve the problem, we need to find the price of a pie and cake slice.
Using the information gathered, the equation is:
<em>x = the cost of the slice of cake.</em>
<em />
2. Simplify/Solve
- Great! we have the price of a slice of cake. ($4.25)
Remember that the pie is of a slice of cake, so now find the price of the pies.
Pie = 
Pie = $1.70
- Awesome! We know a slice of cake costs $4.25 and a slice of pie costs $1.70.
3. Check your work!
<em>Check to make sure the math is done correctly!</em>
Good! It is verified that our calculations are correct.
4. Solve!
1 pie and 2 cakes cost: 
- $10.20 is our final answer!
- Hope this helped!~~ -Astro
Supposed that we are given the equation:
7.20 x 10^-5 = x(0.100+x)^2
So assuming that x is very small so that:
0.100 + x ~ 0.100
and calling it x1, so:
7.20 x 10^-5 = x1 (0.100)^2
Then we simply solve for x1:
x1 = 7.20 x 10^-5 / (0.100)^2
<span>x1 = 7.20 x 10^-3</span>
