Determine the value of c that makes the function f(x y) = c/x-y/ a joint discrete probability density function for x=2,0,2 and y=-2,3
Given: The given function is
[tex]f(x,y)=c(x-y)[/tex]
To find: Here we need to find the value of c for which f(x,y) will be a joint
discrete probability density function.
Solution:
Now, to find c we have,
[tex]\int\limits^3_{-2} \,\int\limits^2_0 {f(x,y)} \, dx dy\\=\int\limits^3_{-2} \,\int\limits^2_0 {c(x-y)} \, dx dy\\\\=\int\limits^3_{-2} \,[2c-2cy]dy\\=10c-5c\\=5c\\The integral should be1.\\So, 5c=1\\[/tex]
∴[tex]c=\frac{1}{5}[/tex]
Therefore, the required value of c is 1/5.

Answer:
317.49508~317.50
Step-by-step explanation:
a=15.937253933193771
b=7.9686269665968858
a²+b²=(15.937253933193771)²+(7.9686269665968858)²
=(253.99606)+(63.49902)
=317.49508

If the inverse of a function is also a function, then
The function is said to be ….?
Answer: Invertible
Step-by-step explanation:
If inverse of a function exists, then the function is said to be invertible. A unique value exits for each given input.
Inverse of a function can be obtained by expressing the given function in terms of y and then replace y by x.

Help please I keep missing the middle one
Answer:
4 + (1/3)w + w = 24
subtract 4 from both sides
(1/3)w + w = 20
multiply both sides by 3 to clear the fraction
w + 3w = 60
4w = 60
Divide both sides by 4
w = 15

Which expression is equivalent to 2^-3/2^-5
Answer:
2^2
Step-by-step explanation:
2^-3/2^-5
We know that a^b / a^c = a^(b-c)
2^-3/2^-5 = 2^( -3 - -5) = 2^(-3+5) = 2^2
if a triangle has one angle that measure 81 degrees and another that measures 47 degrees, what is the measure of the third angle?
Answer: 52
Step-by-step explanation:
81 + 47 is 128.
180 - 128 =52 degrees.

In the circle shown below, The length of chord AB is 24 and the length of OC is 5. What is the radius of the circle with center O
Answer:
radius = 13
Step-by-step explanation:
OC is a perpendicular bisector of AB , then AC = 12
OA is the radius of the circle
Using Pythagoras' identity in right triangle OAC
OA² = OC² + AC²
OA² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
OA = [tex]\sqrt{169}[/tex] = 13
The radius = 13 units
Answer:
13
Step-by-step explanation:
AB is bisected by perpendicular OC so AB is divided into intwo two equal halves.
if AB = 24
AC =[tex]\frac{1}{2} *AB[/tex]
=[tex]\frac{1}{2} *24[/tex]
=12
no join OA and name its length as x
OA = X
OC = 5
AC = 12
when u join O and A it forms a triangle . SO to find OA lets find pythagoras theorem
OC^2 + AC^2 = OA^2
5^2 + 12^2 = OA^2
25 + 144 = OA^2
169 = OA^2
[tex]\sqrt{169}[/tex] = OA
13 = OA
radius is the line joining the centre and any point on the circumference.So here since O is the centre and A is the points on the circumference and they are joined so the line can be named as radius of a circle.
Therefore radius of a circle is 13

Answer: x = 8,-2
Step-by-step explanation:
x^2-6x-16=0
x =[ -(-6)+-sqrt(-6)^2 - 4x1x(-16)/2x1
x = [6+-sqrt 36+64]/2
x = 6+-sqrt 100/2
x = 6 +-10/2
x = 6+10/2, 6-10,2
x = 8, -2
Answer:
Step-by-step explanation:
This is the quadratic equation formula for the roots.
x^2 - 6x - 16 = 0
x = [- (-6) +/- √( (-6)^2 - 4*1*-16) / 2*1
x = (6 +/- √(36 + 64) / 2
x = (6 +/- √(100) / 2
x = (6 +/- 10) / 2
x = 16/2 = 8
x = -4/2 = -2
PLEASE HELP: Click on the graph to choose the correct answer to the equation.
y > 2
(Choose one of the graphs from the image as the answer)
Answer:
The 8th graph.
Step-by-step explanation:
It has a horizontal line over two which indicates that the y axis is known and over 2.
The required graph of the given inequality y > 2 is shown in the attached file, which is the correct answer that would be an option (H).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We have been the given inequality y > 2
Plot the "y=" line (a solid line for y or y, and a dashed line for y or y>). The shade above the line for a "greater than" (y> or y), or below the line for a "less than" (y or y).
It has a horizontal line over two which represents that the y-axis is known and over 2 in the attached graph.
Therefore, the required graph of the given inequality y > 2 is shown in the attached file.
Hence, the correct answer would be option (H).

Answer:
9.89 m
Step-by-step explanation:
AC is the hypotenuse (H)
x is the opposite (O)
O and H are in sine
sin=O/H
H=O/sin
H=7.9/sin(53)
=9.89187169943418
3 SF
9.89 m
Answer:
AC= 13.144
Step-by-step explanation:
cos ∅ = Adjacent/ Hypotenuse
cos (53°) = x/AC
cos (53°) = 7.9/AC
(0.601).(AC)=7.9
AC=(7.9)/(0.601)
AC= 13.144 (3 S.F)

I need help solving both
Answer: The first one is y≤11 and the second question is x>16 Hope that helps Goodbye!
Step-by-step explanation: 1. Add 22 to both sides.
-13+2
−y≥−13+2
2 Simplify -13+2−13+2 to -11−11.
-y\ge -11
−y≥−11
3 Multiply both sides by -1−1.
y\le 11
y≤11
1 Add 22 to both sides.
6+2<\frac{x}{2}
6+2<
2
x
2 Simplify 6+26+2 to 88.
8<\frac{x}{2}
8<
2
x
3 Multiply both sides by 22.
8\times 2<x
8×2<x
4 Simplify 8\times 28×2 to 1616.
16<x
16<x
5 Switch sides.
x>16
x>16
