Answer:
-3
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
To find the slope we need to use 2 points.
For example,
(- 2, 4), (- 1, 1)
m = (4 - 1)/(- 2-(-1)) = 3/(-1) = -3
or
(- 1, 1) , and (1, - 5)
m = (1-(-5))/(-1-1)= 6/-2 = -3
So, if we have a line , we can use any 2 points to find the slope.
To find the difference, we need to subtract the height of the fish from the height of the bird. If we use sea level as 0, then the bird flies at 1,281 feet, and the fish swims at -282 feet.
1,281 - (-282) = <span>1,281 + 282 = 1,563 feet
There is a </span><span>1,563 feet difference between the height of the bird and the depth of the fish</span>
Answer:
Standard Deviation = 5.928
Step-by-step explanation:
a) Data:
Days Hours spent (Mean - Hour)²
1 5 61.356
2 7 34.024
3 11 3.360
4 14 1.362
5 18 26.698
6 22 84.034
6 days 77 hours, 210.834
mean
77/6 = 12.833 and 210.83/6 = 35.139
Therefore, the square root of 35.139 = 5.928
b) The standard deviation of 5.928 shows how the hours students spend outside of class on class work varies from the mean of the total hours they spend outside of class on class work.
It will take 20 seconds to move from one end to another because if 20 feet is moved within 5 seconds, do that 4 more times to get to 80. Finally, multiply 5 by 4 to get 20 seconds.
Less. 600 KM is equal to 600,000 meters
