Answer:
[tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]
Step-by-step explanation:
Explanation
Given that
[tex]h(s) = \frac{1+\sqrt{s} }{1-\sqrt{s} }[/tex]
Differentiating equation (i) with respective to 'x' ,we get
[tex]h^{l} (s) =\frac{1-\sqrt{s}) \frac{1}{2\sqrt{s} } -(1+\sqrt{s})(\frac{-1}{2\sqrt{s} )} }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{\frac{1}{2\sqrt{s} } -\frac{1}{2\sqrt{s} }X\sqrt{s} + \frac{1}{2\sqrt{s} } +\frac{1}{2\sqrt{s} }X\sqrt{s} }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{\frac{2}{2\sqrt{s} } }{(1-\sqrt{s})^{2} }[/tex]
[tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]

Answer:
true
Step-by-step explanation:
the line is going down. if it was positive then it would be going from left all to right going up.
Answer:
Yes
Step-by-step explanation:
A slope is "change in y divided by change in x"
If the change in x is +2 then (if you look at the graph) you see that the change in y will be -1.
Since "change in y divided by change in x" is the slope. Change in y is -1 and change in x is +2.
-1 / 2 = -0.5
and there you have it!
The slope is -0.5, which is a negative number. So the slope is negative.

The question is incomplete. Here is the complete question.
You are designing an automatic coin counter that stacks 50 pennies at a time to be placed in coin wrappers. You plan on measuring the height of the stack to determine the number of coins, but are concerned as to how accurate the method will be. You measure the thickness of 30 penniesm with the data listed below.
a. Based on these data, estimate the height of a stack of any 50 pennies. How accurate is your estimate, at 95% confidence?
b. What percentage of pennies from the population have thickness of at least 1.34mm?
Answer: a. Height = 74.25mm with margin of error of 0.021.
b. 99.38%
Step-by-step explanation:
a. To estimate the height of any 50 pennies, we have to determine the average of thickness of the sample given in the table.
Average is calculated as the sum of all the data divided by the quantity the sample has, so:
[tex]\overline{x}=\frac{\Sigma x}{n}[/tex]
[tex]\overline{x}=\frac{44.56}{30}[/tex]
[tex]\overline{x}=1.485[/tex]
Each coin is estimated to have 1.485 mm of thickness. Then, the height of 50 pennies is
h = 1.485*50
h = 74.25
50 pennies will have an estimate height of 74.25 mm.
Margin of Error expresses the amount of random sampling error the results in a survey can have. It will show how many percentage points the result is from the actual population value.
To calculate it, we have to determine standard deviation of the data.
Standard deviation is
[tex]s=\sqrt{\frac{\Sigma (x-\overline{x})^{2}}{n-1} }[/tex]
[tex]s=\sqrt{\frac{0.09735}{29} }[/tex]
s = 0.058
For a 95% confidence, z-score is 1.96.
Margin is
[tex]E=z.\frac{s}{\sqrt{n}}[/tex]
[tex]E=1.96(\frac{0.058}{\sqrt{30}})[/tex]
E = 0.021
The accuracy of the estimate is 2.1%.
b. The percentage of pennies with thickness at least 1.34mm is represented as P(x>1.34). To calculate it:
P(x>1.34) = 1 - P(x<1.34)
Now, we have to normalize the data:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]z=\frac{1.34-1.485}{0.058}[/tex]
[tex]z=-2.5[/tex]
[tex]P(x<1.34)=P(z<-2.5)[/tex]
Consulting the z table,
[tex]P(z<-2.5)=[/tex] 0.00621
Now, for the percentage:
[tex]P(x>1.34)=1-0.00621[/tex]
P(x > 1.34) = 0.9938 or 99.38%
The percentage of pennies with thickness of at least 1.34mm is 99.38%.

Two nickels have the same value as one ????
Answer:
Quarter
Dime
Step-by-step explanation:
A nickel is 5 cents, and 5*5=25, so 5 nickels is 25 cents. A quarter is equal to 25 cents.
5*2=10, and a dime is equal to 10 cents.
Hope this helps!
Answer:
Five nickels have the same value as one QUARTER
Two nickels have the same value as one DIME
Step-by-step explanation:
a nickel equals 5 cents, so when you have 5 of them, you have 25 cents. a quarter equals 25 cents.
2 nickels equal 10 cents, and a dime equals 10 cents.

Answer:

Step-by-step explanation:
Recall that there are 2π radians in one full rotation and 360 degrees in one full rotation.
Suppose an angle has a measure of 2.1 radians.
This angle (with a measure of 2.1 radians) is what percent of a full rotation?
 %
Use your work in part (i) to determine the measure of the angle in degrees.
 degrees
Answer: (i) This angle is 33.41% of the full rotation.
(ii) 120.38°
Step-by-step explanation:
GIven: Measure of full rotation = 2π radians
Measure of an angle = 2.1 radians.
The percent of this angles of a full rotation = [tex]\dfrac{2.1}{2\pi}\times100\%[/tex]
[tex]=\dfrac{2.1\times7}{2\times22}\times100\% \ \ \ \ [\pi =\dfrac{22}{7}]\\\\=33.41\%[/tex]
i.e. This angle is 33.41% of the full rotation.
In degrees,
[tex]\text{ 2.1 radians}=2.1\times\dfrac{180}{\pi}\\\\=2.1\times\dfrac{180}{3.14}\approx120.38^{\circ}[/tex]
[tex]2.1\text{ radians}[/tex] is [tex]33.4\%[/tex] of a full rotation and is equivalent to [tex]120.2^\circ[/tex]
The relationship between degree and radian measures is
[tex]1\text{ radian}=\dfrac{180}{\pi}^\circ[/tex]
Part 1We want to express [tex]2.1\text{ radians}[/tex] as a percentage of a full rotation.
[tex]\dfrac{2.1}{2\pi}\times100\%=\dfrac{210}{2\pi}\%\\\\\approx33.4\%[/tex]
Part 2How do we determine the measure of an angle (in degrees) given the percentage? Simply multiply the percentage by the complete/full rotation (that is [tex]360^\circ[/tex])
[tex]33.4\%\times360^\circ\\\\=\dfrac{33.4}{100}\times360^\circ\\\\\approx120.2^\circ[/tex]

15. Roberto paid $35.75 for dinner at a restaurant, plus an additional $7.15
tip. What percent of the bill did he pay as a tip? Round to the nearest
percent, if necessary.
Answer:
He paid 17% of the bill as a tip.
Step-by-step explanation:
Paid $35.75 for dinner at a restaurant, plus an additional $7.15 tip.
So in all, he paid 35.75 + 7.15 = $42.9
Tip as a percent:
Tip(7.15) multiplied by 100 and divided by the total(42.9). So
7.15*100/42.9 = 16.7%
Rounded to the nearest percent
He paid 17% of the bill as a tip.
