Answer:
40 mph
Step-by-step explanation:
One hour includes 60 minutes
8/60=0.13(3 repeating)
You only need 15 minutes of time
0.13(3 repeating)*15=2
8+2=10 miles
15 minutes is 1/4 of an hour
10*4=40 mph
The center of the circle that circumscribe about DABC is
.
A circle can be modelled after a expression of the form:
(1)
We can determine all coefficients by knowing three <em>distinct</em> points on plane.
If we know that
,
and
, then the solution of the system of linear equations is:
(2)
(3)
(4)

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

Answer = $55
Because 3 + 7 + 5 = 15
The 3 = black coffee
The 7 = sugar coffee
And the 5 = milk coffee
So then u do 5/15 simplified = 1/3
So then do 1 /3 of $165 = $55
Variance is given by s^2 = [summation (x - mean)^2] / n.
mean = (90 + 75 + 72 + 88 + 85) / 5 = 82
Variance = [(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)] / 5
= [8^2 + (-7)^2 + (-10)^2 + 6^2 + 3^2] / 5
= (64 + 49 + 100 + 36 + 9] / 5
= 258 / 5
Therefore, the value of the numerator of the calculation of the variance of the data set is 258.
