Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.
Answer:
(a) 
and 
(b) The sample variance is 
and the sample standard deviation is 
Step-by-step explanation:
(a)
The sum of these 17 sample observations is
and the sum of their squares is
(b)
The sample variance, denoted by 
, is given by
where 
Applying the above formula we get that
The sample standard deviation, denoted by <em>s</em>, is the (positive) square root of the variance:
Applying the above formula we get that
-2n2 • (4n - 1). Hope this helped
Step-by-step explanation:
X intercept of -5 means the line cuts the x axis at -5 so, mark with a small dot/x at - 5 on the x axis which is the horizontal line
y intercept of 3 means the line cuts/passes thru the y axis at 3. so, mark it with a dot/cross at 3 on the vertical line
now, join the 2 markings together with a straight line
