Answer:
(a) The value of <em>a</em> is 53.35.
(b) The value of <em>a</em> is 38.17.
(c) The value of <em>a</em> is 26.95.
(d) The value of <em>a</em> is 25.63.
(e) The value of <em>a</em> is 12.06.
Step-by-step explanation:
The probability density function of <em>X</em> is:
Here, 22 < X < 55.
(a)
Compute the value of <em>a</em> as follows:
Thus, the value of <em>a</em> is 53.35.
(b)
Compute the value of <em>a</em> as follows:
Thus, the value of <em>a</em> is 38.17.
(c)
Compute the value of <em>a</em> as follows:
Thus, the value of <em>a</em> is 26.95.
(d)
Compute the value of <em>a</em> as follows:
Thus, the value of <em>a</em> is 25.63.
(e)
Compute the value of <em>a</em> as follows:
Thus, the value of <em>a</em> is 12.06.
Answer:
Step-by-step explanation:
Slope of a line passing through two points and
is given by the formula,
Slope =
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '' =
= 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '' =
= ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
