A dozen is 12
multiply 5 * 12 = 60
multiply (3/4) * 12 = 9
Then add together
60 + 9 = 69
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 interior angle plus the exterior angle totals to 180 so you would take 180 and subtract 157.5 and get 22.5
next you would take 360 for the total of degrees that he external angles totals up to.
so 360 divided by 22.5 equals the number of sides you shape has and that would be 16 sides.
Answer:
45.27feet
Step-by-step explanation:
Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)
Note that the velocity of the balloon at maximum height is zero, hence;
v = dh/dt =0
-32t+28.7 = 0
-32t = -28.7
t = 28.7/32
t = 0.897secs
Get the maximum height
Recall that h=−16t²+28.7t+32.4
h = -16(0.897)²+28.7(0.897)+32.4
h= -12.87+25.74+32.4
h = 45.27feet
Hence the maximum height reached is 45.27feet
