You have a triangle with one side with length of 5 (from point 4,-4 to a point on the x-axis) and another side with length of 4 (from point 4,0 to point 4,-4). The third side of the triangle is obviously 3, because of Pythagoras rule. And that third point is on the x axis and 3 units away from point 4,0. So the third point can either be 1,0 or 7,0. Those two points are the answers.
Your answers are -10 and 4
-10+4=-6
In the year 2008 and 2009, the company had profit 2.5 thousand dollars and 1.75 thousand dollars consecutively
In the year 2010 and 2011, the company experienced a loss of 3.3 thousand dollars and 1.4 thousand dollars.
Total profit is 2.5 + 1.75 = 4.55 thousand dollars
Total loss = 3.3 + 1.4 = 4.7 thousand dollars
Total loss is bigger than the total profit so the company needs to make profit in 2012 to break even = 4.7 - 4.55 = 0.37 thousand dollars (this is the least profit the company needs to make)
Since there are no given sample statistics, Let us use the following: n=35, x=24.1, and o=2.7
2-tail test
Using a T-test:
t(24.1) = (24.1-23/[2.7/sqrt(35)] = -2.4103
P - value = 2*P(-100< t < -1.9720, when df = 34)
= tcdf (-100,-2.4103,34) -> using excel
= 0.0107
Answer:
Step-by-step explanation:
The equation of a circle with center (a,b) and radius r, is
From the question, the center of the circle is located at (-6,2) and the radius is
We substitute the center and radius to get:
Simplify to obtain:
