Can anyone explain to me how to do box plots?! I don't understand...

This picture is a reference... The median is the middle number in the set
Q1 is the Upper quartile. You get the first quartile by taking the first half of the set of numbers. You then look and see which one is the one in the middle of that set. That's your Upper quartile.
This apples for the Q2 too. Except you're taking the last set of numbers and finding the middle of that set. This is your upper quartile.
The minimum is the first number in the set.
The maximum is the last number in the set.
Then what you're going to do is order them on the number line by putting the median on first then plot the upper and lower quartile on. Then draw a box around the Q1 and Q2. Now plot the min and max in the number line and draw lines from the box to the min and max. There you go!

alexdok [17]

Answer:

P(120< x < 210) = 0.8664

Step-by-step explanation:

given data

time length = 20 year

average mean time μ = 165 min

standard deviation σ = 30 min

randomly selected game between = 120 and 210 minute

solution

so here probability between 120 and 210 will be

P(120< x < 210) = $P(\frac{120-165}{30}< \frac{x-\mu }{\sigma }$

P(120< x < 210) = $P(\frac{-45}{30}< \frac{x-\mu }{\sigma }$

P(120< x < 210) = P(-1.5< Z < 1.5)

P(120< x < 210) = P(Z< 1.5) - P(Z< -1.5)

now we will use here this function in excel function

=NORMSDIST(z)

=NORMSDIST(-1.5)

P(120< x < 210) = 0.9332 - 0.0668

P(120< x < 210) = 0.8664

Two airplanes are flying to the same airport. Their positions are shown in the graph. Write a system of linear equations that re

wariber [46]

Answer:

Airplane #1 equation: y=5/13x+42/13

Airplane #2 equation: y=1/3x+14

Step-by-step explanation:

So to find the slope of each airplane, you use the formula y2-y1/x2-x1. That means, for airplane#1 the equation will be 9-4/15-2. Simplify this and get 5/13. Then, for airplane#2, the equation will be 12-9/6-15. Simplify this and get 3/-9 and divide each side by 3 to get 1/-3 or -1/3. Next, use point slope formula to find the system of linear equations. Point slope formula is y-y1=m(x-x1). M is the slope. Use any point from the line. In this case, I will use (2,4). Tat means the first airplane's equation would be y-4=5/13(x-2). Then y-4=5/13x-10/13. Then, convert four into a fraction with a denominator of 13. This means, you have to multiply 4 by 13 to get 52/13. Add 52/13 to -10/13 to get 42/13. That means the first equation will be y=5/13x+42/13. The second equation point will be (6,12). This means the equation will be y-12=-1/3(x-6). Simplify this to get y-12=-1/3x+2. Simplify this to get y=1/3x+14. Therefore, Airplane#1 equation will be y=5/13x+42/13 and airplane #2 equation will be y=1/3x+14.

Hope this helps
