The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
a.
is a proper joint density function if, over its support, 
is non-negative and the integral of is 1. The first condition is easily met as long as 
. To meet the second condition, we require
b. Find the marginal joint density of 
and 
by integrating the joint density with respect to 
:
Then
c. This probability can be found by simply integrating the joint density:
(a)7x4=28
2x2=4
28-4=24
24-1=23 points
(b)20/4=7 correct answers
Answer:
Two parallel lines
Step-by-step explanation:
the slopes are the same: slope = 3
f(x) 3x + 5 g(x) = 3x - 2
Pick at least three x values and find their corresponding values for y. Remember the f(x) and g(x) represent y
f(x) = 3x + 5 g(x) = 3x - 2
y = 3x + 5 y = 3x - 2
let x = 0 y = 3(0) + 5 y = 3(0) - 2
y = 5 y = -2
Ordered pair (0, 5) (0, -2)
Let x = 1 y = 3(1) +5 y = 3(1) - 2
y = 8 y = 1
ordered pair (1, 8) (1, 1)
Let x = -1 y = 3(-1) + 5 y = 3(-1) - 2
y = 2 y = -5
ordered pair (-1, 2) ( -1, -5)
Locate the ordered pairs and draw the graph on the lines.
you will graph two parallel lines
More than $36 since its LESS THAN -36
