Answer:
Step-by-step explanation:
Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.
i.e. X is normal with mean = 15 and unknown std deviation
Given that
i.e. P(
z=-1.475 (from normal table)
Hence
Using this we find P(X>17) =
<u>Answer:</u>
The coordinates of endpoint V is (7,-27)
<u>Solution:</u>
Given that the midpoint of line segment UV is (5,-11) And U is (3,5).
To find the coordinates of V.
The formula for mid-point of a line segment is as follows,
Midpoint of UV is ,
As per the formula, =5,
=-11
Here
Substituting the value of we get,
=5
Substituting the value of we get,
=-11
So, the coordinates of V is (7,-27)
