It is an exponential function because it has a common ratio of 1:3
To start, we're given the range that x lies in: from -1 to 4. We know from the fact that
that -1 will be <em /><em>included</em> in that range, so we mark -1 on the number line with a solid circle. We also know from
that, while x can be any value <em>up to</em> 4, it does not <em>include </em>4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be <em>any value within this range</em>, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.

Answer:
The right answer is:
(a) -10.67
(b) 0.7986
Step-by-step explanation:
(a)
According to the question,
<u>X P(X) X.P(X) X2.P(X)</u>
<u>12130 0.002 24.26 294274</u>
<u>-35 0.998 -34.93 1222.55</u>
Now,
or,
hence,
The mean will be:
(b)
According to the question,
n = 12
p = 0.125
q = 1 - p
= 0.875
Now,
⇒
By substituting the values, we get
⇒
⇒
