Time Warner Cable provides television and Internet service to millions of customers. Sup-pose that the management of Time Warner Cable subjectively assesses a probability dis-tribution for the number of new subscribers next year in the state of New York as follows. x f(x) 100,000 .10 200,000 .20 300,000 .25 400,000 .30 500,000 .10 600,000 .05a. Is this probability distribution valid
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

By selling 75 apples, a seller gains the cost price of 15 apples.
find his gain percentage?
Answer:
20%Step-by-step explanation:
In this exercise, we want to convert the sellers gain or say represent the sellers gain as a percentage
step onegiven data
given that he sells a total of 75 apples
and also that he gains 15 apples
step twoTo solve or show the percentage gain, we have to divide the total sales by the profit made and multiply the result by 100, that way we have the percentage gain.
i.e (profit/total sales)*100
= (15/75)*100
= 0.2*100
= 20%
. Rohith purchased a book for Rs.573.75 and a pen for Rs.25.50. His father
gave him a Rs 1000 note. How much money is left with him after
purchasing both the things?
Answer:
Step-by-step explanation:
cost of book = Rs. 573.75
cost of pen = Rs. 25.50
total cost = 573.75 + 25.50 = Rs. 599.25
total money = Rs. 1000
money left with him = 1000 - 599.25 = Rs. 400.75

The midpoint of DG is M(-1,5). One endpoint is D(1,4). Find the
Coordinates of the other endpoint G.
Answer:
G(-3, 6)
Step-by-step explanation:
[tex]midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
Substitute the coordinates of M and D into the formula:
[tex]( - 1,5) = ( \frac{x1 + 1}{2} , \frac{y1 + 4}{2} ) \\- 1=\frac{x1 + 1}{2}& ,&5&= \frac{y1 + 4}{2} & \\ - 1(2)= x1 + 1&, & 5(2) &= y1 + 4 &\\ - 2= x1 + 1&, &10 &= y1 + 4 &\\ x1= - 2 - 1&,& y1 &= 10 - 4 &\\ x1= - 3&, &y1& =6 \: \: \: \: \: \: \: \: \: \: &[/tex]
Thus, the coordinates of G is (-3,6).

Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the origin and (−3, 4).
Answer:
[tex]x = \frac{17}{18}[/tex]
[tex]y = \frac{23}{6}[/tex]
Step-by-step explanation:
Given
[tex]y = 3x + 1[/tex]
[tex]Points = (0,0)\ to\ (-3,4)[/tex]
Required
Determine (x,y) equidistant from the equation and the given point
This question will be answered using distance formula;
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Considering The first Point [tex](0,0)\ to\ (x,y)[/tex]
[tex](x_1 ,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (x,y)[/tex]
The distance is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
[tex]d = \sqrt{0 - x)^2 + (0 - y)^2}[/tex]
[tex]d = \sqrt{(- x)^2 + (- y)^2}[/tex]
[tex]d = \sqrt{x^2 + y^2}[/tex]
Considering the second point: [tex](x,y)\ to\ (-3,4)[/tex]
[tex](x_1,y_1) = (x,y)[/tex]
[tex](x_2,y_2) = (-3,4)[/tex]
The distance is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
[tex]d = \sqrt{(x - (-3))^2 + (y - 4)^2}[/tex]
[tex]d = \sqrt{(x + 3)^2 + (y- 4)^2}[/tex]
[tex]d = \sqrt{x^2 + 6x + 9 + y^2- 8y + 16}[/tex]
[tex]d = \sqrt{x^2 + 6x + y^2- 8y + 16 + 9}[/tex]
[tex]d = \sqrt{x^2 + 6x + y^2- 8y + 25}[/tex]
Equate both values of d
[tex]\sqrt{x^2 + 6x + y^2- 8y + 25} = \sqrt{x^2 + y^2}[/tex]
Square both sides
[tex]x^2 + 6x + y^2- 8y + 25 = x^2 + y^2[/tex]
Collect Like Terms
[tex]6x - 8y + 25 = x^2 -x^2+ y^2 -y^2[/tex]
[tex]6x - 8y + 25 =0[/tex]
Recall that [tex]y = 3x + 1[/tex]
[tex]6x - 8(3x + 1) + 25 = 0[/tex]
[tex]6x - 24x - 8 + 25 = 0[/tex]
[tex]-18x+ 17 = 0[/tex]
[tex]-18x=- 17[/tex]
Solve for x
[tex]x = \frac{-17}{-18}[/tex]
[tex]x = \frac{17}{18}[/tex]
Substitute [tex]\frac{17}{18}[/tex] for x in [tex]y = 3x + 1[/tex]
[tex]y = 3 * \frac{17}{18} + 1[/tex]
[tex]y = \frac{17}{6} + 1[/tex]
[tex]y = \frac{17 + 6}{6}[/tex]
[tex]y = \frac{23}{6}[/tex]

6. DE with endpoints D(-3, -4) and E(4, 2) under the translation
(x, y) + (x + 1, y + 3)
Answer:
D'(-2, -1)
E'(5, 5)
Step-by-step explanation:
DE has the coordinates of the endpoints as D(-3, -4) and E(4, 2).
These points are translated by the rule to give the translated image as D'E',
(x, y) → (x + 1, y + 3)
By following this rule,
D(-3, -4) → D'(-3 + 1, -4 + 3)
→ D'(-2, -1)
E(4, 2) → E'(4 + 1, 2 + 3)
→ E'(5, 5)
Now we can graph these image points having coordinates D'(-2, -1) and E'(5, 5).
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Write 12 32 in simplest form. You must show your work to receive all possible points.
Answer:Start by dividing the numerator and denominator by 2.
12/32 = 6/16
Now that can also be divided by 2.
6/16 = 3/8
That's as far as we can go because 3/8 can not be divided any more.
We could have divided 12/32 by 4 and saved a step.
The required simplest form of the 12 / 32 is 3 / 8.
Given that,
To write 12 32 in simplest form.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
To write 12 / 32 in simplest form,m
= 12 / 32
= 4 * 3 / 2 * 4 * 4
Eliminating common terms that are common in numerator and denominator.
= 3 / 8
Thus, the required simplest form of the 12 / 32 is 3 / 8.

pliz solve this question, pliz pliz
Answer:
If the bisector of AB is at origin (0,0) and A is at (4,0)
we can say that the mid-point of the line AB is at (0,0)
Hence, the point B will be 4 units on the other side of the origin
Therefore, the co-ordinates of B are: (-4,0)
Since the line AB is 4 units to the left and 4 units to the right of the origin,
the length of line-segment AB is 4 + 4 = 8 units
An artist has 8 gallon-sized buckets of paint. The artist uses the paint from the buckets to fill pint-sized cans. What is the greatest number of
cans the artist can fill using the paint from the buckets?
Answer:
64 cans
Step-by-step explanation:
Given
[tex]Gallon = 8[/tex]
Required
Determine the equivalent in pints
The standard unit of conversion;
[tex]1 gallon = 8 pints[/tex]
Multiply both sides by 8
[tex]8 * 1\ gallon = 8 * 8\ pints[/tex]
[tex]8\ gallons = 64\ pints[/tex]
Hence, the artist will need 64 cans
