if there are 20 vakues in a data set in order from smallest to largest what is the median of the data set

1 answer:

5 0

To find the median of 20 values, list the values from smallest to largest then add the 10th and 11th number then divide by 2 and you get your median.

f(x)=\cfrac{1}{\sqrt{x}}\implies f(x)=x^{-\frac{1}{2}}\implies \cfrac{dy}{dx}=-\cfrac{1}{2}x^{-\frac{1}{2}-1}\implies \cfrac{dy}{dx}=-\cfrac{1}{2}x^{-\frac{3}{2}}$

$\bf \cfrac{dy}{dx}=-\cfrac{1}{2}\cdot \cfrac{1}{x^{\frac{3}{2}}}\implies \cfrac{dy}{dx}=-\cfrac{1}{2}\cdot\cfrac{1}{\sqrt[2]{x^3}}\implies \cfrac{dy}{dx}=-\cfrac{1}{2\sqrt{x^3}}\\\\
-------------------------------\\\\
d)\\\\
f(t)=t^3+3t^2-6\implies \cfrac{dy}{dt}=3t^2+6t^1-0\implies \cfrac{dy}{dt}=3t^2+6t$

When constructing a perpendicular bisector, why must the compass opening be greater the 1/2 than the length of the segment?

Alex787 [66]

Answer.

It is Important to open the compass more than half the length so that the arcs made would meet.

Explanation.

When you want to construct a perpendicular line to a line segment, say line AB, the follow steps are taken;

1) Open your compass to a radius greater than half the line AB.

2) With A as your center make an arc on top and below line AB.

3) Using the same radius and with B as our center, make other arcs on top and below line AB to meet the first arcs on both sides of the line.

4) Join the two intersection of the two arcs to cut line AB at M.

In so doing the line AB is said to be bisected perpendicularly. If the compass was opened less than half line AB, then the arcs could not have meet.

What are the total amount of choices possible if an individual is to create a 4 digit password using the digits 0 through 9 incl

Serga [27]

Answer:

10000 options

Step-by-step explanation:

There are 10 options of digit from 0 to 9. It means there are 10 options for the first slot, 10 for the 2nd slot, 10 for the 3rd slot, and 10 for the last slot of each of the 4 slots of the password. For all 4 passwords the total amount of choices would be

$10 * 10 * 10 * 10 = 10^4 = 10000 options ranging from 0000 to 9999$

Which fraction is equivalent to 2/5? A. 4/10 B. 2/10 C. 1/2 D. 4/6

Lelechka [254]

Hey there James!

So, just remember, 2/5 is almost half of 1.

When it is almost half of 1, this means that it would have to be 2.5/5

This would mean that 4/10 would be your answer, because it is almost half of 1 also.

Hope this helps.
