In ascending order the integers are arranged from the left to right of the integer line. The arrangements are shown below.

The arrangement of the set of integers in increasing order is as follows:

Every positive integer is greater than a negative integer. Zero is less than every positive integer. Zero is greater than every negative integer. The greater the number, the lesser its opposite,i.e., If a and b are two integers such that a>b, then -a<-b.

The following are the solutions to the given problems by using binomial probability principle:

1.) P(X ≤ 3)

P(X ≤ 3) = p(x = 0) + p(x = 1) + p(x = 2) + p(x = 3)

Use a binomial probability calculator :

P(X ≤ 3) = 0.277 + 0.365 + 0.231 + 0.093

P(X ≤ 3) = 0.966

2.) P(X < 3)

P(X < 3) = p(x = 0) + p(x = 1) + p(x = 2)

Use a binomial probability calculator :

P(X < 3) = 0.277 + 0.365 + 0.231

P(X < 3) = 0.873

3.)P(X ≥ 4)

P(X ≥ 4) = p(x = 4) + p(x = 5) +...+ p(x = 50)

Use a binomial probability calculator :

P(X ≥ 4) = 0.034

4.) P(1 ≤ X ≤ 3)

P(1 ≤ X ≤ 3) = p(x =1) + p(x =2) + p(x =3)

Use a binomial probability calculator :

P(1 ≤ X ≤ 3) = 0.365 + 0.231 + 0.093

P(1 ≤ X ≤ 3)= 0.689

D.) σ(X)

Answer: c

Step-by-step explanation:

A is 190 divided by 125

B is 190 multiplied with 125 (product of the two numbers)

D is the sum of 190 and 125 (addition)

the difference will be found by subtracting the smaller number from the bigger number

The population of the town in the year 1995 will be 61415.

From the information, the population of a town was 980 in 1970 and the population has been growing at a rate of 18% each year.

Therefore, it should be noted the difference in the number of years will be:

= 1995 - 1970

= 25 years

Therefore, the population of the town in the year 1995 is:

= 980 × (1 + 18%)^25

= 980 × (1.18)^25

= 980 × 66.6686

By using percentage, the deductible amount is $103.73 for each paycheck. So, option b is correct.

We are provided by some percentage here. A percentage is a part of a whole that is expressed in hundredths.

Sally paid 38% of her annual health insurance premium of $4,350.00 and left with the 62%.

62% of $4,350.00 is equal to $2697

      62/100 x 4,350.00 = 2697

So, the net amount that Sally has to pay is $2697 in equal distribution from her 26 paychecks throughout the calendar year.

Therefore, each paycheck will be deducted as = $2697/26

                                                                        = $103.73

Answer:

It would go 3 to the write of x.

Step-by-step explanation:

If B is the 3 spaces to the left of x and T is three spaces to the right of x, x would be in the middle.

In the picture, you have B=2, X= 5

so T goes if X is the midpoint of BT is

X= (B+T)/2

5 x 2= 2+ T

10 = 2+T

therefore, T = 8

Answer:

130 degrees

Step-by-step explanation:

When two lines intersect, the opposite angles are equal, therefore, in this example, 7c+36 = 5c+40. We can find c using this equation.
7c+36 = 5c+40
7c-5c = 40-36
2c = 4
c = 4/2 therefore c=2

now that we know c is equal to 2, we can find out both of those angles.
therefore 5c+40 = (5*2)+40 = 10+40= 50
and 7c+36 = (7*2)+36 = 14 +36 = 50

now we know that those two angles add up to 100.

to find the sum of x and the angle opposite to x, subtract 100 from 360
360-100 = 260

since the angle opposite of x is equal to x, x+x = 260
2x=260
x=260/2 = 130

x is 130 degrees

Answer:

x = 130

Step-by-step explanation:

7c + 36 and 5c + 40 are vertically opposite angles and are congruent , so

7c + 36 = 5c + 40  ( subtract 5c from both sides )

2c + 36 = 40 ( subtract 36 from both sides )

2c = 4 ( divide both sides by 2 )

c = 2

Then

7c + 36 = 7(2) + 36 = 14 + 36 = 50

5c + 36 and x are a linear pair and sum to 180° , that is

50 + x = 180 ( subtract 50 from both sides )

x = 130

Answer:

2'

Step-by-step explanation:

An eleven-foot long board must be cut into three pieces so that one piece is 1-foot shorter than half the length of the longest piece and the other piece is 3 feet shorter than the longest piece. How long is the shortest piece?

board 1 = 0.5L - 1

board 2 = L - 3

board 3 = L

so:

(0.5L - 1) + (L - 3) + L = 11'

0.5L - 1 + L - 3 + L = 11'

combine L on left side:

2.5L - 4 = 11

add4 from both sides:

2.5L - 4 + 4 = 11 + 4

2.5L = 15

divide both sides by 2.5:

2.5L/2.5 = 15/2.5

L = 6

Formula for boards are, substitute in L = 6:

board 1 = 0.5L - 1

= 0.5(6) - 1

= 3 - 1

= 2'

board 2 = L - 3

= 6 - 3

3'

board 3 = L

= 6

shortest board is board 1 at 2'

Rectangles are defined by the location of its four vertices set on Cartesian plane, whose images must be found by using a transformation known as translation, whose formula is defined below:

P'(x, y) = P(x, y) + T(x, y)

Where:

If we know that B(x, y) = (3, 2), C(x, y) = (3, 7), D(x, y) = (7, 7), E(x, y) = (7, 2) and T(x, y) = (- 7, 0), then the images of the vertices are:

B'(x, y) = (3, 2) + (- 7, 0)

B'(x, y) = (- 4, 2)

C'(x, y) = (3, 7) + (- 7, 0)

C'(x, y) = (- 4, 7)

D'(x, y) = (7, 7) + (- 7, 0)

D'(x, y) = (0, 7)

The equation of the line that has a slope of 7 and passes through the point (4, -2) is: y = 7x - 30.

If we are given a point on a line (x, y), and we know the slope (m) of the line, we can expressed the equation of the line in slope-intercept form as y = mx + b.

Given the following:

Slope of the line, m = 7

A point on the line = (4, -2).

Find the value of b by substituting x = 4, y = -2, and m = 7 into y = mx + b:

-2 = 7(4) + b

-2 = 28 + b

-2 - 28 = 28 + b - 28 [subtraction property of equality]

-30 = b

b = -30

From the table, it can be seen that when x = -1, the function y = 2x + 7 has a value of 5 and the function y = -x + 4 has a value of 5.

Therefore, the graph of the two functions will intersect at (1, 5)

       The length of the line segment bridging two points on a plane is known as the distance between the points. d=((x2 - x1)2 + (y2 - y1)2) is a common formula to calculate the distance between two points.

         Except for when the points coincide, distances in geometry are always positive. The distance between points A and B is equal to their respective distances. We take two points A(a,b) and B into consideration in order to calculate the formula for the distance between two points in the plane (c,d).

     In coordinate geometry, the distance between two given points is calculated using the distance formula. D=(x2x1)2+(y2y1)2 D = (x 2 x 1) 2 + (y 2 y 1) 2 is the formula for calculating the distance between two points (x1,y1) (x 1, y 1) and (x2,y2) (x 2, y 2).

    Say, for instance, that you are asked to determine the distance between two points at ( -6,-2 ) and ( -1,10).

First step:  

Give x 1, y 1, x 2, and y 2 their respective assignments.

Consider the cases where (x 1, y 1 ) = ( -6,-2)) and (x 2, y 2 ) = ( -1,-10).

      x1 = -6

      y1 =- 2

      x2 =  -1

      y2  = 10

Second Step:

Replace in the Distance Formula

Now that we know the numbers for x1, y1, x2, and y2, we can enter them into the Distance Formula.

d = √(-6,-2)² + (-1-10)²

   = √(8)² + (11)²

   = √16+22

If the length of the room is 17 inches one the architect's plan, the actual length of the room in feet if the scale of the plan is 1.25 inches to 3 feet is

40.8 feet

The length of the room on the architect's plan = 17 inches

The scale of the plan = 1.25 inches to 3 feet

That means

The length on the plan/ The actual length = 1.25 inches / 3 feet

Substitute the value of the length on the plan in the equation

17 / The actual length = 1.25/3

The actual length of the room  = 17/0.42
