Answer:
The teams can be placed in 479,001,600 ways.
Step-by-step explanation:
To solve this question, we want to know in how many ways 12 elements can be arranged.
Number of possible arrangements of x elements:
The number of possible arrangments of x elements is given by:
In this question:
12 teams, so arrangment of 12 elements.
The teams can be placed in 479,001,600 ways.
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
Answer: 1 song is 1.3 the total cost of 25 songs would be 33.75
Answer:
Step-by-step explanation:
From the diagram in the image attached:
Base of triangle = 
Base of triangle = 
Height = 9cm
Area of triangle = (0.5) × base × height
Area of triangle = 
Area of rectangle = Length × width
Area of rectangle = 
Shaded area = area of rectangle - area of triangle
Shaded area = 
Shaded area = 
Like other graphs, they use an x axis, and a y axis. It shows how one variable can affect another, hence the x and y (independent variable versus the dependent variable). With scatter plots you can use it to find a line of best fit that shows an average correlation relationship of the data. Scatter plots also allow you to find any outliers (those little dots that aren't in a pattern, correlation, or area with the majority of other points). It usually shows a relationship between TWO sets of data. :) :>
Hope this helps! :3 :>
