Answer:
<em>The distance of the line is 10.82</em>
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
The graph clearly shows the points (-5,4) (4,-2), thus the distance is:
The distance of the line is 10.82
So the rise over run is 5/-4
To start off take 10 degrees/96 cups
If you look at the pattern the degrees go up by 5 and the cups go down by 4
So I believe the answer should be
25 degrees = 84 cups
Answer:
Volume = 803.84 cubic inches
Step-by-step explanation:
Volume = πr²h
= 3.14 x 8 x 8 x 4
= 3.14 x 256
= 803.84 cubic inches
Step-by-step explanation:
15 long
12 wide
10 high
we need all for walls
hight times length two times ( these are the front and back walls )
hight times width two times ( These are the side walls )
the roof is
width times length (only once as only the ceiling)
same measurement as the floor
can you work it out with that
please mark brainiest
Answer:
![Interval = [666.78, 781.62]](https://tex.z-dn.net/?f=Interval%20%3D%20%5B666.78%2C%20781.62%5D)
Step-by-step explanation:
Given
The data for 25 undergraduates
Solving (a): Range and Standard deviation
The range is:
From the dataset:
So:
The standard deviation is:
First, calculate the mean
So, the standard deviation is:
Solving (b): The interval of the 95% of the observation.
Using the emperical rule, we have:
![Interval = [\bar x - 2*\sigma, \bar x+ 2*\sigma]](https://tex.z-dn.net/?f=Interval%20%3D%20%5B%5Cbar%20x%20-%202%2A%5Csigma%2C%20%5Cbar%20x%2B%202%2A%5Csigma%5D)
![Interval = [724.2 - 2*28.71, 724.2 + 2*28.71]](https://tex.z-dn.net/?f=Interval%20%3D%20%5B724.2%20-%202%2A28.71%2C%20724.2%20%2B%202%2A28.71%5D)
