STEP 1: Compute the mean
The mean of the dataset is the sum of the elements divided by their number:
STEP 2: Compute the residuals
You have to compute the difference between every element and the mean:
Step 3: Square the residuals:
Step 4: Sum the squared the residuals:
Step 5: Divide by the number of elements in the dataset:
Step 6: Consider the square root of the result:
The formula we used is
where 
is the standard deviation, 
are the elements in the dataset, 
is the number of elements in the dataset, and 
is the mean of the dataset.
Answer:
The Answer is A. 2/5
Step-by-step explanation:
The way i Divide fractions is by if you take the second fraction and swap the numbers around, you can do 7/24 TIMES 48/35. then you multiply the numbers NOT in a crossway like 7 times 35 butin a straight way so its 7 times 48. Doing so will get you 336/840. I simplified this answer by 6 and got 56/140 then i simplified it again by 4 to get 14/35 and once more i simplified it by 7 to get 2/5.
Answer:
So, to find the number we have to subtract 65 from 180 180-65 = 115 So 115 will be added to 65 to get 180.
Area of a cylinder is the area of the top + the area of the bottom + the area of the wrap-around (lateral)
top: pi*r*r=81pi
bottom: 81pi
lateral: 2pi*r*h=18pi*h, h is unknown, but you don't have to solve it.
add them up: 81pi +81pi + 18h*pi=1850
pi*h=(1850-162pi)/18, (plug this in the volume formula below.)
volume of a cylinder: the area of the base × the height =81pi*h
volume=81[1850-162pi)/18]
use your calculator: V=6036
please double check my calculation by yourself.
Answer:
16m² + 4m - 6
Step-by-step explanation:
Hello There!
For this one all we need to do is combine like terms
7m²-(-9m²)=16m²
2m-(-2m)=4m
-3-3=-6
so the answer would be
16m² + 4m - 6
