Explanation:
All of the points must be contained within a circle that will circumscribe an equilateral triangle of area 1. (We refer to this as the inscribed triangle.) Any points on the circle that do not form an equilateral triangle will form a triangle with an area less than 1. Likewise for any points within the circle.
The circle can be circumscribed by an equilateral triangle whose side length is double that of the inscribed triangle. Since the side length is double, the circumscribing triangle will have an area 2² = 4 times that of the inscribed triangle.
The inscribed triangle has an area of 1, so the circumscribing triangle must have an area of 4.
Answer:
auditory nerve
Step-by-step explanation:
the auditory nerve carries sound signals to the brain. The cochlea picks up sound waves and makes nerve signals.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
iTones charges $10 per month, and $1 per song.
Music Mine charges $7 per month and $1.50 per song.
<u>To calculate the total cost for each option, we need to use the following formulas:</u>
iTones:
Total cost= 10 + 1x
x= number of songs
Music Mine:
Total cost= 7 + 1.5x
x= number of songs
The equation for direct variation is y=kx where k is the constant of variation.
Answer: Choice C)
--------------------------------------
mean = xbar = (2400+1750+1900+2500+2250+2100)/6
mean = 2150
Subtract the data values from the mean to get
2400-2150 = 250
1750-2150 = -400
1900-2150 = -250
2500-2150 = 350
2250-2150 = 100
2100-2150 = -50
The differences are: 250, -400, -250, 350, 100, -50
Then you square those values and add up the squares
(250)^2 + (-400)^2 + (-250)^2 + (350)^2 + (100)^2 + (-50)^2 = 420,000
