Answer:
Step-by-step explanation:
In this problem we are calculating the relative frequency conditional by columns.
Therefore the sum of the frequencies of each column must be equal to 1.
Then we use this condition to calculate the values of a and b
So:
Finally
Answer:
638.75
Step-by-step explanation:
Well you can actualy do this on a calculator If put in proporly use the 2nd button and push (sin) to get a tax percentage.
The value of the deal should be $40,000.
remember that 5% as a decimal is .05.Let x = value of deal
The equation would be .05x = $2000
Divide both sides by 0.05.
x=40,000
Answer:
center at (6, -4) r = √7
Step-by-step explanation:
(x – 6)^2 + (y + 4)^2 = 7
This is in the form
(x – h)^2 + (y - k)^2 = r^2
Where (h,k) is the center of the circle and r is the radius of the circle
Rearranging the equation to match this form
(x – 6)^2 + (y -- 4)^2 = sqrt(7) ^2
The center is at (6, -4) and the radius is the sqrt(7)
