The corresponding joint probability distribution is:
X\Y 0 1
0 1/12 1/4
1 1/6 1/2
Since X and Y are independent, the joint probability distribution is simply the product of their marginal probability distributions:
f(x,y) = f(x) × f(y)
Therefore, we have:
f(0,0) = f(0) ×f(0) = (1/3) × (1/4) = 1/12
f(0,1) = f(0) × f(1) = (1/3) × (3/4) = 1/4
f(1,0) = f(1) × f(0) = (2/3) × (1/4) = 1/6
f(1,1) = f(1) ×f(1) = (2/3) × (3/4) = 1/2
Therefore, the corresponding joint probability distribution is:
X\Y 0 1
0 1/12 1/4
1 1/6 1/2

Warren is tiling his bathroom. He wants to cut three different sizes of square tiles. Tile A must be 5 square inches, tile B must be 10 square inches, and tile C must be 15 square inches. He needs to know the side length of each tile. Part A In the table, note your guesses and checks to find the length of tile A, which has an area of 5 square inches. Estimate the value to five decimal places.
Answer:
2.36068 inches
Step-by-step explanation:
Let us recall that the area of a square is given by;
A = l^2
This is because, all the sides of a square are equal hence l=b
When A = 5 square inches
5 = l^2
l = √5
l = 2.36068 inches

Use the Distributive Property to rewrite the algebraic expression. 7(6m + 7)
wrong answers reported
Step-by-step explanation:
first, distribute 7 to 6m (this means 7 • 6m)
7 • 6m = 42m
then distribute 7 to 7 (which is 7 • 7)
7 • 7 = 49
your simplified expression is 42m + 49. i hope this helps! have a great day <3
Lorenzo tiene 4 cajas de huevo, cada uno con 50 huevos y 3 cartones del mismo producto con 10 de ellos ¿Cuántos huevos hay en total?
Responder:
240 huevos
Explicación paso a paso:
Número de cajas de huevos = 4
Huevos por caja = 50
Total de huevos en caja = 50 * 4 = 200 huevos
Número de cajas = 3
Número de huevos por caja = 10
Total de huevos en caja = 10 * 4 = 40 huevos
Huevos totales = (huevos en caja + huevos en cartón)
Total = (200 + 40) = 240 huevos

The winning times for a race are shown in the table.
Which answer describes the rate of change from year 2 to year 4?
- The winning time increased by an average of 0.267 second per year from year 2 to year 4.
- The winning time increased by an average of 0.8 second per year from year 2 to year 4.
- The winning time increased by an average of 0.4 second per year from year 2 to year 4.
- The winning time increased by an average of 0.475 second per year from year 2 to year 4.
Answer: The winning time increased by an average of 0.4 second per year from year 2 to year 4.
The winning time for a race displayed in the table would be:
C). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Find the increase in winning time:
Given that,
Year Winning Time(seconds)
1 27.5
2 28.4
3 28.7
4 29.2
5 29.44
Hence, The total change in the time is,
= (0. + 0.3 + 0.5 + 0.24)/4
= 0.485 seconds
Now, If we round off, it becomes 0.5 seconds.
Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.
Thus, ''Option C'' is the correct answer.

Answer:
A=51
a=22.2
c=28.6
Step-by-step explanation:
∠A=180-90-39
=51
a/sin51=18/sin39
a=22.2
c/sin90=18/sin39
c=28.6
Answer:
A=51 degrees
a=14.6 units
c=30
Step-by-step explanation:
A=180-90-39=51
a= (a=a; o=18; angle=39)
Tan(39)=a/18
0.8=a/18
14.6=a
c= (h=c; o=18; angle=39)
Sin(39)=18/c
0.6=18/c
0.6c=18
c=30

Find the product of (x + 5)(x − 5). Group of answer choices x2 − 10x + 25 x2 + 10x + 25 x2 − 25 x2 + 25
First I will tell you the formula for this, then I will show how we got the formula, then the answer.
Formula -> (x+a)(x-a)=x^2-a^2
We can find this by expanding the 2 ( )
(x+a)(x-a)=x^2+ax-ax-a^2=x^2-a^2
Now we can use this to solve your problem, the 5 is the a in the formula.
(x+5)(x-5)=x^2-5^2=x^2-25. Therefore choosing the 3rd answer choice.

Step-by-step explanation:
Area of the given triangle = 1/2 * base * height
=1/2*17*4
=17*2
=34 ft.sq
Answer:
34 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 17 and h = 4 , then
A = [tex]\frac{1}{2}[/tex] × 17 × 4 = [tex]\frac{1}{2}[/tex] × 68 = 34 ft²

I'm very confused, please help!
Answer:
Step-by-step explanation:
g(x)=3x−2
g(−2)= 3(-2) - 2 (after substituting -2 for x): g(-2) = -6 - 2 = -8
g(0)= 3(0) - 2 = -2
g(5)= 3(5) - 2 = 13
