Answer:

Step-by-step explanation:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates  of 2 points on a line by the difference of the x-coordinates  of those same 2 points .Teachers use different words for the y-coordinates  and the the x-coordinates . Some call the y-coordinates  the rise  and the x-coordinates  the run . Others prefer to use Δ notation and call the y-coordinates Δ  , and the x-coordinates the Δ  .These words all mean the same thing, which is that the y values are on the top of the formula (numerator) and the x values are on the bottom of the formula (denominator)!The slope of a line going through the point (1, 2) and the point (4, 3) is 13. Remember: difference in the y values goes in the numerator of formula, and the difference in the x values goes in denominator of the formula.Can either point be (1,1) ? There is only one way to know! First, we will use point (1, 2)  as 1,1, and as you can see  : the slope is: 13 . Now let's use point (4, 3)  as 1,1, and as you can see  , the slope simplifies to the same value: 13point (4, 3) as (1,1) =2−12−1=3−24−1=13 point (1, 2) as (1,1) =2−12−1=2−31−4=−1−3=13 Answer: It does not matter which point you put first. You can start with (4, 3) or with (1, 2) and, either way, you end with the exact same number! 1/3

Example 2 of the Slope of A line The slope of a line through the points (3, 4) and (5, 1) is −32 because every time that the line goes down by 3(the change in y or the rise) the line moves to the right (the run) by 2.This is because any vertical line has a Δ or "run" of zero. Whenever zero is the denominator of the fraction in this case of the fraction representing the slope of a line, the fraction is undefined. The picture below shows a vertical line (x = 1). vertical line The slope of a horizontal line is zero This is because any horizontal line has a Δ or "rise" of zero. Therefore, regardless of what the run is (provided its' not also zero!), the fraction representing slope has a zero in its numerator. Therefore, the slope must evaluate to zero. Below is a picture of a horizontal line -- you can see that it does not have any 'rise' to it.

Answer:

a). k = 0.75

b). y = 0.75x

Step-by-step explanation:

a). Graph is showing the relation between number of pages (P) illustrated by Indira and number of days taken (D).

   P ∝ D

   P = kD

   Where 'k' is the proportionality constant.

   k = [tex]\frac{P}{D}[/tex]

  From the graph attached,

  For a point with ordered pair (2, 1.5),

  k = [tex]\frac{1.5}{2}[/tex]

  k = 0.75

b). Equation representing the relation between number of pages and number of days will be,

  P = 0.75D

  y = 0.75x

First we need the slope which is finding from the following equation.

slope = y(B) - y (A) / x (B) - x(A)

Suppose ;

A = ( 0 , 0 ) & B = ( 10 , 5 )

Thus :

slope = 5 - 0 / 10 - 0

slope = 5 / 10

slope = 1 / 2

__________________________

We have following equation to find the point-slope form of the linear functions.

y - y(0) = s × ( x - x(0) )

__________________________

y(0) & x(0) are the coordinates of the point which line through it like A = ( 0 , 0 ) or B = ( 10 , 5 ).

s = slope

__________________________

I choose point A to put in the equation.

So :

y - ( 0 ) = 1/2 × ( x - ( 0 ) )

y - 0 = 1/2 × x - 1/2 × 0

y = 1/2 × x

y = x/2

Done....

Answer: A) Nathan’s because his sample was more random

Step-by-step explanation: sampling methods quiz on edge

Nathan's sample is likely to be the most valid. Nathan's because his sample contained elements of the population.

In order to gather information on a service, product, or process, a survey is described as an act of looking at a process or asking a predetermined sample of people. Surveys used to gather data ask a specific set of individuals about their beliefs, actions, or knowledge.

Given, To find out how much time cyclists are in a race train on average each week, Nathan and Jordan develop questionnaires. Every fifth cyclist who crosses the finish line after a race is surveyed by Nathan. Jordan takes a survey of the top five cyclists who cross the finish line.

Since Nathan's sample contained elements of the population.

and it is more random.

The sample used by Nathan is probably the most reliable. Nathan's because the population was represented in his sample.

The equation -42 - 7 + 10x = -7 + 6x has one solution x = 10.5.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

-42 - 7 + 10x = -7 + 6x

Combine like terms in the equation,

-49 + 10x = -7 + 6x

Add 49 to both sides,

10x = 42 + 6x

Subtract 6x from both sides,

4x = 42

Divided both sides by 4 into the equation, and we get

x = 10.5

Thus, the equation has one solution x = 10.5.

Answer:

26.2 hours

Step-by-step explanation:

From the given information:

The objective is to determine the value of the 50th percentile.

The median is the 50th percentile, which categorically divides the data into two equal parts. It is a number separating the higher half of a data sample from the lower half. This implies that the median stands in place for the 50th percentile of the data.

Thus, the 50th percentile value is 26.2 hours

Answer:

(a) The inequality for the number of items, x, produced by the labor, is given as follows;

250 ≤ x ≤ 600

(b) The inequality for the cost, C is $1,000 ≤ C ≤ $3,000

Step-by-step explanation:

The total time available for production = 1000 hours per week

The time it takes to produce an item on line A = 1 hour

The time it takes to produce an item on line B = 4 hour

Therefore, with both lines working simultaneously, the time it takes to produce 5 items = 4 hours

The number of items produced per the weekly labor = 1000/4 × 5 = 1,250 items

The minimum number of items that can be produced is when only line B is working which produces 1 item per 4 hours, with the weekly number of items = 1000/4 × 1 = 250 items

Therefore, the number of items, x, produced per week with the available labor is given as follows;

250 ≤ x ≤ 1250

Which is revised to 250 ≤ x ≤ 600 as shown in the following answer

(b) The cost of producing a single item on line A = $5

The cost of producing a single item on line B = $4

The total available amount for operating cost = $3,000

Therefore, given that we can have either one item each from lines A and B with a total possible item

When the minimum number of possible items is produced by line B, we have;

Cost = 250 × 4 = $1,000

When the maximum number of items possible, 1,250, is produced, whereby we have 250 items produced from line B and 1,000 items produced from line A, the total cost becomes;

Total cost = 250 × 4 + 1000 × 5 = 6,000

Whereby available weekly outlay = $3000, the maximum that can be produced from line A alone is therefore;

$3,000/$5 = 600 items = The maximum number of items that can be produced

The inequality for the cost, C, becomes;

$1,000 ≤ C ≤ $3,000

The time to produce the maximum 600 items on line A alone is given as follows;

1 hour/item × 600 items = 600 hours

The inequality for the number of items, x, produced by the labor, is therefore, given as follows;

250 ≤ x ≤ 600

(a) The inequality for the number of items, x, produced by the labor, is given as follows;

250 ≤ x ≤ 600

(b) The inequality for the cost, C is $1,000 ≤ C ≤ $3,000

Inequality is a statement shows greater the, greater then equal to, less then,less then equal to between two algebraic expressions.

The total time available for production = 1000 hours per week

The time it takes to produce an item on line A = 1 hour

The time it takes to produce an item on line B = 4 hour

Therefore, with both lines working simultaneously, the time it takes to produce 5 items = 4 hours

The number of items produced per the weekly labor = 1000/4 × 5 = 1,250 items

The minimum number of items that can be produced is when only line B is working which produces 1 item per 4 hours, with the weekly number of items = 1000/4 × 1 = 250 items

Therefore, the number of items, x, produced per week with the available labor is given as follows;

250 ≤ x ≤ 1250

Which is revised to 250 ≤ x ≤ 600 as shown in the following answer

(b) The cost of producing a single item on line A = $5

The cost of producing a single item on line B = $4

The total available amount for operating cost = $3,000

Therefore, given that we can have either one item each from lines A and B with a total possible item

When the minimum number of possible items is produced by line B, we have;

Cost = 250 × 4 = $1,000

When the maximum number of items possible, 1,250, is produced, whereby we have 250 items produced from line B and 1,000 items produced from line A, the total cost becomes;

Total cost = 250 × 4 + 1000 × 5 = 6,000

Whereby available weekly outlay = $3000, the maximum that can be produced from line A alone is therefore;

$3,000/$5 = 600 items = The maximum number of items that can be produced

The inequality for the cost, C, becomes;

$1,000 ≤ C ≤ $3,000

The time to produce the maximum 600 items on line A alone is given as follows;

1 hour/item × 600 items = 600 hours

The inequality for the number of items, x, produced by the labor, is therefore, given as follows;

250 ≤ x ≤ 600

Hence the inequality for the number of items, x, produced by the labor, is 250 ≤ x ≤ 600 and the inequality for the cost, C is $1,000 ≤ C ≤ $3,000
