Answer: A. 6.5
Step-by-step explanation:
Here, the given set = { 15, 19 3, 12, 17, 2, 2, 8}
Mean, 
Number of elements, n = 8
Thus, the standard deviation, 
⇒ Option A is correct.
They both equal 1/x.
Start by breaking the radicand up into a product of known factors.
<em>x = markers</em>
<em>y = colored pencils</em>
12x = y
x= 72
y = 6
Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 <em>(12x = 6) </em>which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.
You would multiply 4 on both sides
5x=2
then you would divide 5 on both sides
x=2/5
Answer:
12 shirts
Step-by-step explanation:
You cant have one fourth if a shirt so if you have 12 yards with one shirt needing 1 yard you get 12
