What percent of the data is greater than the median?A box-and-whisker plot. The number line goes from 0 to 20. The whiskers range from 2 to 19 and the box ranges from 6.5 to 18. A line divides the box at 17.a.20%c.50%b.25%d.80%
Answers
1) Consider that the 1st Quartile corresponds to 25%, the Median is equivalent to 50% of the data, the Third Quartile to 75% of the data as the sketch below:
Notice that the Median is that bar inside the box, also known as the 2nd Quartile.
2) So the percentage of the data greater than the median is:
[tex]75\%-50\%=25\%[/tex]

When oil was spilled out in the middle of a lake, it spread out on the surface of the water in a circular pattern. The radius of the circular pattern increased at a rate of 4 feet per minute.((() = 4tft/min)Find the radius and area of the circular pattern of oil 5 minutes after the oil starts to spread.
Answers
The radius of the circle increases by 4 feet per minute. When 1 minute has passed, the radius is 4 feet, and when 5 minutes have passed, the radius will be 5 times that:
[tex]4\times5=20[/tex]The radius of the circle after 5 minutes is 20 feet.
To find the area, we use the formula for the area of a circle:
[tex]A=\pi r^2[/tex]Using the radius of 20 feet:
[tex]r=20ft[/tex]And substituting it into the formula for the area:
[tex]\begin{gathered} A=\pi(20ft)^2 \\ A=\pi(400ft^2) \end{gathered}[/tex]Using:

There is a triangle with sides a, b, and c and angles A, B, and C.
And,

A = 22°
C = 13°
To find:
The value of a.
Explanation:
It is given that,
There is a triangle with sides a, b, and c and angles A, B, and C.
And,
c = 9 cm
A = 22°
C = 13°
That implies,
By using sine law,
[tex]\begin{gathered} \frac{\sin C}{c}=\frac{\sin A}{a} \\ \Rightarrow\frac{\sin13\degree}{9}=\frac{\sin22\degree}{a} \\ \Rightarrow a=\frac{9\times\sin22\degree}{\sin13\degree} \\ \Rightarrow a=14.9875 \\ \Rightarrow a=15cm \end{gathered}[/tex]Hence, the value of a is 15cm.

[tex]f(x)=\frac{1}{\frac{\sin(x)}{\cos(x)}\frac{1}{\sin (x)}}[/tex]Simplifying:

Answers
The number of vehicles that are secondhand is 34.
There is a garage. The total number of vehicles in the garage is 60. The vehicles are for sale. The vehicles are all either new or secondhand. The number of vehicles that are cars is 28. The other vehicles are vans. Seven of the cars are secondhand. Five of the vans are new. We have to find the total number of second-hand vehicles.
First of all, we will find the number of vans in the garage. The number of vans is 60 - 28 = 32. The number of cars that are second-hand is 7. The number of vans that are second-hand is 32 - 5 = 27.
The total number of second-hand vehicles in the garage is the sum of the numbers of second-hand cars and vans.
N = 7 + 27
N = 34
Hence, 34 vehicles are second-hand in the garage.

Answer:

Explanation:
First, we find the equation fo the line point-slope form.
The slope of the line is
[tex]m=\frac{209-202}{63-60}=\frac{7}{3}[/tex]With the slope of the line in hand, we now write the point-slope form of the equation using the point (63, 209)
[tex]y-209=\frac{7}{3}(x-63)[/tex]With the equation of the line in hand, we now use it to find the value of y at x = 72.
Putting in x = 72 in the above equation gives
[tex]y-209=\frac{7}{3}(72-63)[/tex][tex]y-209=\frac{7}{3}\cdot9[/tex][tex]y-209=21[/tex]adding 209 to both sides gives
[tex]y=230[/tex]which is our answer!
Hence, the predicted height for someone with a femur length of 72 cm is 230 cm.
