Answer:
The coefficient of variation after the tax is imposed is 0.033
Step-by-step explanation:
Given
--- mean
--- variance

Required
The coefficient of variation
The coefficient of variation is calculated using:

After the tax, the new mean is:



And the new variance is:



So, we have:




The answer is d I’m pretty sure
Answer:
6xy+4x
Step-by-step explanation: You start off by gathering the like terms (which are 9xy & -3xy) and then you just keep 4x there. You then subtract 9xy-3xy=6xy and bring down the 4 since it has no like terms. So it’s 6xy+4x.
Answer:
q = 2
Step-by-step explanation:
0.5-0.125q=(q-1)/4
At first, we have to multiply both the sides by 4.
4 × (0.5 - 0.125q) = q - 1
or, 2 - 0.5q = q - 1
now, we change the side by taking constant into the right side and the number into the left side.
2 + 1 = q + 0.5q
or, 3 = q (1 + 0.5)
or, 3 = 1.5 q
or, 1.5 q = 3
or,
= (3 ÷ 1.5) [Dividing both the sides by 1.5]
or, q = 2
Therefore, q = 2
Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.
