6/5=6+0.5=6+½+=6½
6½ is the answer
Step-by-step explanation:
Volume of square pyramid
= (Base length)² * (Height/3).
Therefore we have 8 = 2² * (h/3).
=> 8 = 4 * (h/3), h/3 = 2, h = 6.
Hence the height is 6 feet. (1)
Answer:
A sqrt(x+2) - sqrt(x)
Step-by-step explanation:
2
--------------
sqrt(x) + sqrt(x+2)
Multiply top and bottom by sqrt(x) - sqrt(x+2)
2 sqrt(x) - sqrt(x+2)
------------------------ * --------------------------
sqrt(x) + sqrt(x+2) sqrt(x) - sqrt(x+2)
FOIL the denominator
2 (sqrt(x) - sqrt(x+2))
------------------------------
sqrt(x^2) - sqrt(x) sqrt(x+2) + sqrt(x) sqrt(x+2) - sqrt(x+2)^2
2 sqrt(x) - 2 sqrt(x+2)
------------------------------
x - (x+2)
Distribute the minus sign
2 (sqrt(x) - sqrt(x+2))
------------------------------
x - x-2
2 (sqrt(x) - sqrt(x+2))
------------------------------
-2
Cancel the 2 in the top and bottom
(sqrt(x) - sqrt(x+2))
------------------------------
-1
Distribute the -1
sqrt(x+2) - sqrt(x)
It's 0.4825 time 100 equal 48.25
Options:
- Yes; everyone who doesn't exercise is by definition unhealthy.
- Yes; the correlation coefficient is above 0.5, so that implies causation.
- No; the data doesn't suggest a causation, and many people are healthy who don't exercise.
- No; poor health and not exercising are completely unrelated.
The answer is the third option "No; the data doesn't suggest a causation, and many people are healthy who don't exercise." Correlation is two data set that are linked or connected together so in this case it would be a correlation because all of the data is close and connected to each other.
Hope this helps!
