Answer: yes, it is valid
Step-by-step explanation:
Given the following probability distribution :
X ________f(x)
100,000___ .10
200,000__ .20
300,000 __ .25
400,000 __ .30
500,000 ___.10
600,000 ___.05
To examine the validity of the distribution :
Each individual observation or point must have probability value in within the range (0 < p ≤ 1)
Where p = probability value.
The sum of the individual probabilities must add up to 0
(0.1 + 0.2 + 0.25 + 0.3 + 0.1 + 0.05)
= 1
Since the two consitions are meet, then, the probability distribution is valid

Lcm of 12,16,24,32,36
Answer:
288
Step-by-step explanation:
24 is a multiple of 12, and 36 is a multiple of 12, so the LCM of 24, 32, and 36 will also be the LCM for 12 and 16.
24 = 2^2 * 3
32 = 2^5
36 = 2^2 * 3^2
LCM = 2^5 * 3^2
LCM = 288

Find the equation of the line in slope intercept form parallel to 5x−5y=−2 and goes through the point (−10,4) y=?
Answer:
y = x + 14
Step-by-step explanation:
given
5x−5y=−2, we'll rearrange this into slope - intercept form
5x + 2 = 5y
5y = 5x + 2 (divide both sides by 5)
y = x + (2/5)
recall that the general equation of the slope-intercept form of a linear equation:
y = mx + b, the value of m represents the slope of the line
in our case, comparing the above equations, it is clear that the slope m = 1.
We are given that our line is parallel to the above line, hence it will also have a slope of 1.
if we substitute m = 1 into the general equation, we will get
y = x + b
in order to find the value of b, we will substitute the given point (-10,4) into the equation:
4 = -10 + b (add 10 to both sides)
b = 4 + 10
b = 14
hence our equation is y = x + 14

Point C is located at (2,8). If it is reflected across the x axis, where will C be located?
Answer:
(2, -8)
Step-by-step explanation:
The answer is (2, -8) because when you reflect a point across the x-axis, the x-coordinate always remains the same, but the y-coordinate will change. In other words, the y-coordinate becomes the opposite (signs change). In this case, since the y-coordinate was positive 8, when you reflect the point across the x-axis, the y-coordinate will change to -8

Hope you can answer
Answer:

Explanation:
As you can see they both have an absolute value because they are both in between the 2 lines. So you have to change both of them into a positive number. You would get 5.9+22 which would equal 27.9

simply 4x+6=6(x+1)-2x
Answer:
Many solutions
Step-by-step explanation:
First, you distribute the 6 into the parenthesis:
4x+6=6(x+1)-2x
4x+6=6x+6-2x
4x+6=4x+6
subtract 6 from both sides
4x=4x
All real numbers can be the solution

Find the value of x
Answer:
x° = 123
Step-by-step explanation:
this triangle is isoceles so it has 2 congruent angles.
let y be the second angle
the sum of a triangle's angle is 180°
[tex]180 = 66 + y + y \\180 = 66 + 2y[/tex]
add [tex]-66[/tex] to both sides
[tex]180 - 66 = 2y + 66 - 66 \\114 = 2y[/tex]
divide both sides by 2
[tex]\frac{114}{2} = \frac{2y}{2}[/tex]
[tex]57 = y[/tex]
we khow that [tex]x + y = 180[/tex]
[tex]x + y = 180 \\x + 57 = 180[/tex]
add -57 to both sides
[tex]x + 57 - 57 = 180 - 57 \\x = 123[/tex]

What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have, point (21, 20)
So, Adjacent side= 21 and opposite side= 20
Using Pythagoras theorem
H= √ 21² + 20²
H= √441 + 400
H= √841
H= 29 unit
So, the trigonometric ratio
cos [tex]\theta[/tex] = Adjacent side/ H
cos [tex]\theta[/tex] = 21/29
Thus, the exact value of cos [tex]\theta[/tex] is 21/29.

17 like chocolate only1 likes mango only5 like strawberry only4 like chocolate and strawberry only4 like noneLet:
[tex]C \to Chocolate[/tex]
[tex]M \to Mango[/tex]
[tex]S \to Strawberry[/tex]
So, we have:
[tex]C = 28[/tex]
[tex]M = 15[/tex]
[tex]S = 20[/tex]
[tex]n(C\ n\ S) = 8[/tex]
[tex]n(M\ n\ S) = 11[/tex]
[tex]n(C\ n\ M) = 7[/tex]
[tex]All = 4[/tex]
[tex]n(U) = 50[/tex] -- the population
(a) Chocolate only.
This is calculated as:
[tex]C\ only = C - n(C\ n\ S) - n(C\ n\ M) + All[/tex]
So, we have:
[tex]C\ only = 28 - 8 - 7 + 4[/tex]
[tex]C\ only = 17[/tex]
(b) Mango Only
This is calculated as:
[tex]M\ only = M - n(M\ n\ S) - n(C\ n\ M) + All[/tex]
So, we have:
[tex]M\ only = 15 - 11 - 7 + 4[/tex]
[tex]M\ only = 1[/tex]
(c) Strawberry only
This is calculated as:
[tex]S\ only = S - n(M\ n\ S) - n(C\ n\ S) + All[/tex]
So, we have:
[tex]S\ only = 20 - 11 - 8 + 4[/tex]
[tex]S\ only = 5[/tex]
(d) Chocolate and strawberry
This has already been given as:
[tex]n(C\ n\ S)\ only=n(C\ n\ S) - All[/tex]
[tex]n(C\ n\ S)\ only=8 - 4[/tex]
[tex]n(C\ n\ S)\ only = 4[/tex]

The midpoint of GH are M(4,3) and D(5,-6). The coordinates of the endpoint are?
Answer:
The endpoint coordinates are (3,12)
Step-by-step explanation:[tex]\frac{5+x^{2} }{2} =4[/tex] [tex]\frac{-6+y^{2} }{2} = 3[/tex]
You multiply 4 by 2 which gives you 8 and write the equation[tex]5+x^{2} =8[/tex] then you subtract 5 from 8 to get 3 for the x coordinate.
You multiply 3 by 2 which gives 6 and writhe the equation[tex]-6+y^{2}=6[/tex] then you substitute the -6 for +6 and add +6 and 6 to get 12 for the y coordinate.
To check use the midpoint formula with coordinates D and your endpoint coordinates[tex]\frac{5+3}{2}=\frac{8}{2} =4 \\[/tex] [tex]\frac{-6+12}{2} =\frac{6}{2} =3[/tex] and you get the answer for the midpoint which is (4,3)
