Before sending track and field athletes to the Olympics, the U. S. Holds a qualifying meet. The upper box plot shows the top 12 men's long jumpers at the U. S. Qualifying meet. The lower box plot shows the distances (in meters) achieved in the men's long jump at the 2012 Olympic games. Which pieces of information can be gathered from these box plots?
We require median, interquartile range, outliers, minimum and maximum value.
What are statistics?
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data.
From the upper box plot representing the top 12 men's long jumpers at the U.S. Qualifying meet, we can gather the following pieces of information:
The median (middle value) of the data is around 7.6 meters, as indicated by the line in the center of the box.
The interquartile range (IQR), which is the range between the first and third quartiles, is approximately 0.4 meters, as indicated by the height of the box.
There are some outliers or values that fall outside the range of the box, which is represented by the dots or asterisks outside the box.
The minimum and maximum values for the data are around 7.3 meters and 8.0 meters, respectively, as indicated by the lower and upper ends of the whiskers.
From the lower box plot representing the distances achieved in the men's long jump at the 2012 Olympic games, we can gather the following pieces of information:
The median (middle value) of the data is around 8.0 meters, as indicated by the line in the center of the box.
The interquartile range (IQR), which is the range between the first and third quartiles, is approximately 0.5 meters, as indicated by the height of the box.
There are some outliers or values that fall outside the range of the box, which is represented by the dots or asterisks outside the box.
The minimum and maximum values for the data are around 7.5 meters and 8.4 meters, respectively, as indicated by the lower and upper ends of the whiskers.
The main difference between the two box plots is the median value, which is 0.4 meters apart and the IQR for the Olympic games is slightly bigger than the Qualifying meet.
Hence, we require median, interquartile range, outliers, and minimum and maximum values.

Coroline runs 3 1/2 miles in 22 1/4 minutes how many miles does she run per minute
Answer:
To determine the number of miles Coroline runs per minute, we need to first convert the distance she runs to a fraction of a mile and the time it takes her to run that distance to a fraction of an hour.
3 1/2 miles is equivalent to 3 + 1/2 = 3 + 1/(2*1) = 7/2 miles.
22 1/4 minutes is equivalent to 22 + 1/4 = 22 + 1/(4*1) = 23/4 minutes.
To convert the time to hours, we can divide the number of minutes by the number of minutes per hour. There are 60 minutes per hour, so we have:
23/4 minutes / (60 minutes/hour) = (23/4) / (60/4) = 23/60 hours
To determine the number of miles Coroline runs per minute, we can divide the distance she runs by the time it takes her to run that distance:
(7/2 miles) / (23/60 hours) = (7/2) / (23/60) = (760) / (223) = 420/46
Simplifying, we have:
420/46 = 9 1/23
Therefore, Coroline runs approximately 9 1/23 miles per minute.
Step-by-step explanation:
Answer:
she runs 0.078 miles per minute.

Adrian has $1 worth of nickels and dime. He has twice as many nickels as dimes. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Adrian has. Define the variables that you use to write the system.
Answer: We can use two variables, x and y, to represent the number of dimes and nickels Adrian has, respectively.
We know that Adrian has twice as many nickels as dimes, so we can write the equation:
y = 2x
We also know that the total value of the coins is $1, and since nickels and dimes have different values, we can write the equation:
0.05y + 0.1x = 1
So the system of equations is:
y = 2x
0.05y + 0.1x = 1
These equations can be solved simultaneously to find the number of nickels and dimes that Adrian has.

Answer:
g(-3) = 2
Step-by-step explanation:
g(x) = |x| - 1, x < 1 You would use this equation for finding g(-3). Since -3 is less than 1.
g(x) = |x| - 1, x < 1 ← You can ignore the x<1 part.
g(-3) = |-3| - 1 Input the value -3 as x. The absolute value of x is always g(-3) = 3 - 1 positive.
g(-3) = 2 Simplified
Next,
g(x) = x²- 10, 1 ≤ x ≤ 3 You would use this equation for finding g(3). Since 3 is equal to 3.
g(x) = x²- 10, 1 ≤ x ≤ 3 ← You can ignore the 1 ≤ x ≤ 3 part.
g(3) = (3)²- 10 Input the value 3 as x.
g(3) = 9 - 10 Simplify
g(3) = - 1
Then,
g(x) = [tex]\frac{1}{6}[/tex]x, x > 3 You would use this equation for finding g(6). Since 6 is greater than 3.
g(x) = [tex]\frac{1}{6}[/tex]x, x > 3 ← You can ignore the x > 3 part.
g(6) = [tex]\frac{1}{6}[/tex](6) Input the value 6 as x.
g(6) = [tex]\frac{6}{6}[/tex] Simplify
g(6) = 1
Answer: g(-3) = 2 results in the largest value/output.

x - 6 = 12 add 6 to both sides of the equation
x - 6 + 6 = 12 + 6 simplify
x = 18
3x-1 = 11 add 1 to both sides of the equation
3x -1 + 1 = 11 + 1
3x = 12 now divide both sides by 3
3x/3 = 12 / 3 simplify
x = 4
Find the value of x.
Use statement and reason format.
By using properties for angles we can find and solve some linear equations, there we can see that x = 30°.
How to find the value of x?Remember that the sum of the interior angles of a triangle must give 180°, and we also know that the angle defined by a line is 180°.
Let's define N as the angle located at vertex N of the right triangle in the left side, we then can write:
2x + 90° + N = 180°
And we also can write the linear equation:
105° + 45° + N = 180°
Solving this one, we can find the value of N.
N = 180° - 45° - 105° =30°
N = 30°
Replacing that in the equation with x we will get:
2x + 90° + 30° =180°
2x = 180° - 90° - 30°
2x = 60°
x = 60°/2 = 30°
The value of x is 30°.
