12, because 150/25=6x2 is 12
<span>A polygon is a closed figure made by joining line segments, where each line segment intersect exactry two other line segments.
A polygon is said to be a regular polygon if the sides are all of the same length.
Thus, the figures that are polygon are:
</span><span>Figure A which has 6 sides all made of line segments.
Figure B which is a regular hexagon, having 6 sides made all of segments.
</span><span>Figure D has 7 sides which are all segments.</span>
Answer:
y = mx
Step-by-step explanation:
= x ( multiply both sides by m to clear the fraction )
y = mx
An example of a situation where the measures of central tendency can be applied is when analyzing the test scores of a Math exam taken by 11 people.
<h3>What is an example of measures of central tendency in use?</h3><h3 />
Assuming that 11 people took a Math exam that was graded out of 20 and got the results:
6, 8, 9, 10, 10, 14, 15, 15, 15, 18, 18
The median in this set would be 14. This would therefore show us what the person with the middle score got which is useful in knowing the whether people were above the middle score, or below it.
The mode in this dataset is 15 which shows that 15/20 was the score that was most acquired by people who took the exam.
The mean is:
= (6 + 8 + 9 + 10 + 10 + 14 + 15 + 15 + 15 + 18 + 18) / 11
= 12.5
On average therefore, people got a score of 12.5 in this example. This gives an overall view of the difficulty of the exam.

First find equation
center is (h,k) then
(x-h)^2+(y-k)^2=r^2
given
(7,0) is center
(x-7)^2+y^2=r^2
also given (2,0)
(2-7)^2+0^2=r^2
(-5)^2=r^2
25=r^2
(x-7)^2+y^2=25 is equation
take derivitive of both sides, implicit differntiaton
2(x-7)+2y dy/dx=0
2(x-7)=-2y dy/dx
(7-x)/y=dy/dx
at (2,0)
(7-2)/0
undefined
that means the line is x=something
(2,0)
the equation is x=2
