The formula for the volume of a cylinder is pi x radius^2 x height, so after substituting the values, we get 3.14 x 3^2 x 4. First, we find the value of 3^2, which is 9. 3.14 x 9 equals 28.26, so now we have 28.26 x 4, which gives us 113.04. So the volume of the cylinder is 113.04. :)
Answer:
short piece is 42 inches :)
Step-by-step explanation:
Step 1: Calculate the 0.035 that you already know how to do.
Step 2: Calculate 1-0.035 = 0.965
Step 3: Look at the Z table and find 0.965 (or as close to this value as possible)
<span>Step 4: Look at the far left of the row containing 0.965 </span><span> 1.8</span>
<span>Step 5: Look at the top of the column containing 0.965 </span><span> 0.01</span>
<span>Step 6: Add these two values </span><span> 1.81</span>
<span>Step 6 is your z value that corresponds to that level of confidence.</span>
Answer:
$75
Step-by-step explanation:
Answer is 1.5
You would first find the mean, you add all together then divided it by the numbers that it has, they have 4 number -3, -2, -1, 2 in this problem.
Add all number together divided it by 4, you'll get -1, (-3 + -2 + -1 + 2) ÷ 4 = -1) Then you subtract the mean by the numbers you used to get your mean so in this case it is 3, -2, -1, 2.
-3-(-1)= -2
-2-(-1)= -1
-1-(-1)= 0
2-(-1)= 3
Then you add the answers up but you have to turn the negative numbers to positive like -2 turns into just 2 and so does -1 to 1. (2+1+0+3= 1.5) Then you divide the 6 by how many numbers there are so in this case there are 4 numbers so you do 6 divided by 4 and you get 1.5. (Trust me I learned this)
