Let y be a random variable with p. d.f. ce-4y for y ≥ 0.

(a) determine c.

(b) what is the mean, variance, and squared coefficient of variation of y where the squared

coefficient of variation of y is defined to var(y )/(e[y ])2?

(c) compute pr{y < 5}.

(d) computepr{y > 5|y > 1}.

(e) what is the 0.7 quantile (or 70th percentile) where the 0.7 quantile is the point q such that pr{y > q} = 0.7?

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
