Answer:

The correct answer is y = -2x + 5/2

Step-by-step explanation:

y = mx + b.  is the y intercept form of a line.

To find the  y = mx + b. form

It is given that,

4x + 2y = 5

2y = -4x + 5

Dividing both sides by 2 we get,

2y/2 = (-4x + 5)/2

y = -4x/2 + 5/2

y = -2x + 5/2

Here m = -2 and b = 5/2

Answer:

D) 115

the inside angles of a triangle always (ALWAYS) add up to 180, add 75 and 40. You get 65. Then you know that a straight line means it is 180 degrees so you subtract 65 from 180. you get 115 degrees

Missing angle is 115

x= -4/3 + 2/3 square root of 13 or x= -4/3 + -2/3 square root of 13 !!

Answer:

Step-by-step explanation:

3x² + 8x = 12

3x² + 8x - 12 = 0

a=3, b=8, and c=-12.  Solving with quadratic formula:

x = [ -b ± √(b² - 4ac) ] / 2a

x = [ -8 ± √(8² - 4(3)(-12)) ] / 2(3)

x = (-8 ± √208) / 6

x = (-8 ± 4√13) / 6

x = -4/3 ± 2/3 √13

The answer would be 0.

you would add -4v on the left to -4v to the right to get 0. Then you would add -12 on the left to -12 on the right to get 0.

Answer:

x < - 11

Step-by-step explanation:

Given

4 + 2x = - 18 ( subtract 4 from both sides )

2x < - 22 ( divide both sides by 2 )

x < - 11

Answer:

It would take 4 men 37 hrs and 12 mins to complete the same task.

step-by-step explanation:

Let X be the time the four men would use to complete the task.

From the question, 6 men completed a task in 24 hrs and 48 mins

But

[tex]24 \: hrs \: 48 \: mins = 24(60mins) + 48 \: mins=1488 \: mins[/tex]

Using ratio and proportion

[tex]6 \: men:1488 \: mins[/tex]

[tex]4 men:x\:mins[/tex]

if more, less divides and if less, more divides.

4 men required more time to complete the task

Hence:

[tex]x = \frac{6}{4} \times 1488 \: mins[/tex]

[tex]x = 2232 \: mins[/tex]

x = 37 hrs 12 mins

Hi there! Here's the answer and how I got that answer!!

Answer:

11

The change in the Median would be 11 instead of 11.5 because the total amount of numbers became odd when the outlier is removed. This allowed for the step of having to solve for two middle numbers to be avoided and therefore only leave you with the answer simple as 11 instead of having to solve between two numbers!

Step-by-step explanation:

With all the numbers (including the outlier) the median would be 11.5.

Here's how:

First sort least to greatest and cancel out the numbers until you get to the one on the middle.

9, 9, 11, 12, 14, 28

If you have two middle numbers add them together and then divide by two.

11+12=23

23/2= 11.5

So your median with the outlier is 11.5.

Now if you take out the outlier, which in this case I'm assuming its 28. Let's re-look for the median once more!

First sort least to greatest and cancel out the numbers until you get to the one on the middle.

9, 9, 11, 12, 14

Now because there is an odd amount of numbers your left to only one middle number, 11.

This means if the outlier is removed the median would change to be 11.

Answer: 2x+3y

Step-by-step explanation: look at picture

To find the missing side in a triangle with a given perimeter, subtract the lengths of the known sides from the total frame. This is based on the sum of the lengths of all sides of a triangle, which equals its circumference.

We need to understand a simple rule about triangles to find the missing side of a triangle where the perimeter is 4x + 3y. The sum of all sides of a triangle equals its edge. So, if we know the length of the other two sides, we can subtract their sum from the total circumference to find the size of the missing side.

For example, if we know that the other two sides of the triangle are 2x and y, respectively, the missing side would be calculated by subtracting the sum of these sides from the given perimeter.

4x + 3y = perimeter
2x + y = known sides
missing side = (4x + 3y) - (2x + y)

Note: This method assumes that x and y values are provided. If they're unknown, we will require additional equations to solve for x and y before calculating the length of the missing side.

Answer:

Expected value = $8.89

Step-by-step explanation:

cost of playing game = $1

winning if sum is odd = $10

winning if sum is 4 or 8 = $5

winning if sum is 2 or 12 = $50

two dice rolled, possible outcomes =

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

total no. of outcomes = 36

now according to the table of outcome with respect to winning money, we can calculate expected value by multiplying the probability of each roll with winning amount associated with each roll. and subtract the amount that we paid for the game that is $1.

E(x) = 1/36*($50) + 1/18*($10) + 1/12*($5) + 1/9*($10) + 5/36*($0) + 1/6*($10) + 5/36*($5) + 1/9*($10) + 1/12*($0) + 1/18*($10) + 1/36*($50)

= 25/18 + 5/9 + 5/12 + 10/9 + 0 + 5/3 + 25/36 + 10/9 + 0 + 5/9 + 25/18

Expected value = $8.89

Subtract the amount that was paid to play the game that is $1.

$8.89 - $1 = $7.89

A profit of $7.89 is expected every-time the game is played.

The statements that are true about polygons are:

A closed polygonal chain of connected line segments makes up a polygon, a plane shape. The edges or sides of a closed polygonal chain are the individual pieces. The polygon's vertices or corners are the places where two edges converge.

Each side of a polygon is the same length, and each angle is the same size. For instance, in a square, every side is the same length and every angle is 90 degrees. There is at least one interior angle that is more than 180 degrees in a concave polygon. A concave polygon will have at least one point that is inside it if a side or diagonal is expanded.

Answer:

k=ab

Step-by-step explanation:

a=k/b

a(b)=(k/b)(b)---multiple b to both sides to isolate k

k=ab

Answer:

k is the constant of variation.

Step-by-step explanation:

In direct variation:

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

In inverse variation:

[tex]y\propto \frac{1}{x}[/tex]

[tex]y=\frac{k}{x}[/tex]

[tex]yx=k[/tex]

In both cases k is the constant of variation

The given equation is

[tex]a=\frac{k}{b}[/tex]

We need to find the value of k in this equation.

First we have to isolate k on one side of the equation.

Multiply both sides by b to isolate k on right side.

[tex]a\times b=\frac{k}{b}\times b[/tex]

Cancel out the common factors.

[tex]ab=k[/tex]

Interchange the sides of the equation.

[tex]k=ab[/tex]

It means a and b are inversely proportional.

Therefore, the k is the constant of variation.

Step-by-step explanation:

Since we have given that

[tex]1,\dfrac{1}{8},\dfrac{1}{27},\dfrac{1}{64},...............\dfrac{1}{n^3}[/tex]

So, we can see the pattern:

General term of the series is given as

So, we just put the value of n = 7, to get the required denominator:

[tex]\dfrac{1}{7^3}=\dfrac{1}{343}[/tex]

Hence, the denominator of the seventh term is 343.

Thus, Third option is correct.

Hello There!

The length of the hypotenuse is 10.

We know what 2 sides are 6 and 8.

To find the third side we use the formula a^2 + b^2 = c^2

So we multiply 6 by 6 which equals 36 and then multiply 8 by 8 which equals 64.

Next we add 64 and 36 together and we get 100.

Next, we square root 100 and get 10.

10 is the length of the hypotenuse.

I think it would be “B”

Answer:

Option B.

Step-by-step explanation:

Given information: [tex]m\angle A=48^{\circ},\angle E=90^{\circ},\angle EMS=59^{\circ}[/tex].

According to the angle sum property of a triangles, the sum of interior angles of a triangle is 180°.

Apply angle sum property on triangle AEJ.

[tex]\angle A+\angle E+\angle J=180^{\circ}[/tex]

[tex]48^{\circ}+90^{\circ}+\angle J=180^{\circ}[/tex]

[tex]138^{\circ}+\angle J=180^{\circ}[/tex]

Subtract 138 from both sides.

[tex]\angle J=180^{\circ}-138^{\circ}[/tex]

[tex]\angle J=42^{\circ}[/tex]

The measure of angle J is 42°.

According to exterior angle property, the sum of two interior angles of a triangle is equal to the third exterior angle.

Apply exterior angle property on triangle JMS.

[tex]\angle EJA+\angle JSM=\angle EMS[/tex]

[tex]42^{\circ}+\angle JSM=59^{\circ}[/tex]

Subtract 42 from both sides.

[tex]\angle JSM=59^{\circ}-42^{\circ}[/tex]

[tex]\angle JSM=17^{\circ}[/tex]

The measure of ∠JSM is 17°.

Therefore, the correct option is B.

Answer:

an = 5 + 2n

Step-by-step explanation:

Each time it increases by the same amount (2), so this is an arithmetic sequence:

an = a₁ + d (n - 1)

Given a₁ = 7 and d = 2:

an = 7 + 2 (n - 1)

an = 7 + 2n - 2

an = 5 + 2n

Check our answer:

n=1: a₁ = 5 + 2(1) = 7

n=2: a₂ = 5 + 2(2) = 9

n=3: a₃ = 5 + 2(3) = 11

n=4: a₄ = 5 + 2(4) = 13

The pattern represents the arithmetic progression and the explicit formula for the nth term is a(n) = 2n + 5

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a sequence:

7, 9, 11, 13…

The above pattern represents the arithmetic progression.

The first term a = 7

Common difference d = 2

nth term:

a(n) = 7 + (n - 1)(2)

a(n) = 2n + 5

Thus, the pattern represents the arithmetic progression and the explicit formula for the nth term is a(n) = 2n + 5
