Based on the graph, the expected total value of the donations in October would be $460.

When donations were 5 in number, the expected value was £30.

When donations were 8, the expected value was £50.

When donations were 15, the expected value was £90.

The slope of the line is:

= (90 - 50) / (15 - 8)

= 5.71

The y-intercept as seen on the graph is 0.

The equation of the line is therefore:

y = 5.71x

The expected value of £80 in donations is therefore:

y = 5.71 x 80

= $460

 A sequence is defined by an order of values and/or elements that have a relationship of variation as a ratio or proportion that makes them predictable.

 The first thing to do in this problem is to compare the behavior of the first three trials (variation between each number):

75, 79, 83

   We must find an expression that models a variable behavior of 4 starting at 75

An = A1 + (n - 1)x : Where x = 4

A(4) = 75 + (4 - 1)4

A(4) = 87

A(5) = 75 + (5 - 1)4

A(5) = 91

The midpoint is at ([tex]\frac{10\sqrt{3} }{2} , \frac{9}{2} , \frac{9\sqrt{2} }{2}[/tex])

In the given statement is

To find the midpoint of the line segment joining the pair of points

S(6√3, 4,4√2) and T(4√3, 5, √2)

Midpoint:

The coordinates of the midpoint of a line segment are the average of the coordinates of the end points.

m = (A +B)/2

If we are given three points and we wish to find the midpoint of those points, we need to use the midpoint formula m =(  [tex]\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} , \frac{z_{1} +z_{2} }{2}[/tex] )

where:

(x1 , y1 ,z1) are the coordinates of the first point:

(x2 , y2 , z2) are the coordinates of the second point:

Now, We are given the three points S(6√3, 4,4√2) and T(4√3, 5, √2)

Solving for the midpoint , we have,

m = ([tex]\frac{6\sqrt{3}+4\sqrt{3} }{2} ,\frac{4+5}{2} , \frac{4\sqrt{2}+5\sqrt{2} }{2}[/tex])

m = ([tex]\frac{10\sqrt{3} }{2} , \frac{9}{2} , \frac{9\sqrt{2} }{2}[/tex] )

Hello, I have a Wonderfull website that can help you with this question. (Mathgenius.com) it should pull it up. its all and every subject you can imagine.

Answer:

Chicago to Cleveland- 350 miles

Cleveland to Cincinnati-250 miles

Cincinnati to Chicago-300 miles

Type of triangle formed? - Scalene

Step-by-step explanation:

so I first give each of them a letter, so I chose a for Chicago to Cleveland, b for Cleveland to Cincinnati, and c for Cincinnati to Chicago. Then I write some equations.
a+b+c =900

b=c-50

a=50+c

i then plug the a and b equation into the first one to get

50+c+c-50+c=900

The fifties cancel out, so we are left with 3c =900 so c=300

From this we can figure out the rest by substituting in 300 for c in the an and b equations.
300-50=250

300+50=350

A particular kind of relation called a function is one in which every input value has only one and only one output value. The value of an input is the independent value, but the value of an output is dependent on the value of the input.

The independent variable is the cause. The other study factors have no impact on its value. The dependent variable is effect. Its value is affected by changes in the independent variable.

It is an independent variable that has no bearing on the other factors you are attempting to evaluate. For example, age may be an independent variable.

The graph's x-axis (horizontal line) should contain the independent variable, and the y-axis should contain the dependent variable (vertical line).

C)The price of a shirt is $7, and the price of a cap is $3.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

x+y=10

2x + 4y = 26

solving, we get,

x=7  &  y=3

Generally, If the rock is falling at a rate of 5 inches per second, then you can easily calculate how deep below the surface of the lake it was after 5 seconds by multiplying 5 by 4.

After four seconds, the rock will have dropped -20 inches.

Because Lisa's hand is five feet above the water's surface, we need to add five to the distance between her hand and the rock in order to calculate how far away it is.

After solving the equation we have concluded that if f(x)=-3 x+7 and g(x)=-7 x+3 , then the value of f(-3)-g(3) is -8

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

f(x) = -3x + 7

f(-3) = -3(-3) + 7 = 9 + 7 = 16

g(x) = -7x + 3

g(-3) = -7(-3) + 3 = 21 + 3 = 24

Given that line AT bisects angle CAR, the measure of angle TAR is 35 degree.

Given the data in the question;

Since Line AT bisects ∠CAR

m∠CAR = 2 × m∠CAT

9x + 7 = 2( 5x )

We solve for x

9x + 7 = 10x

10x - 9x = 7

x = 7

We know that a bisector divides a line or angle into two equal halves.

Hence, m∠CAT = m∠TAR

m∠TAR = m∠CAT = 5x

m∠TAR = m∠CAT = 5(7)

m∠TAR = m∠CAT = 35°

Answer:

I think the answer is ∞ which is the third option, undefined.

Answer: a) $3.57   b) 600 g

Step-by-step explanation:

a)  1 kg=1000g

Let's do the proportion:

$7.00 - 1000 g

  $x    -  510 g

Hence,

[tex]\displaystyle\\x=\frac{7*510}{1000} \\\\x=\frac{3570}{1000} \\\\x=3.57\ dollars[/tex]

b)  

Let's do the proportion:

$7.00 - 1000 g

$4.20 -    x g

Hence,

[tex]\displaystyle\\x=\frac{4.2*1000}{7} \\\\x=\frac{4200}{7} \\\\x=600 g[/tex]

a) The cost of a taro that weighs 510 grams is, $3.57

b) The weight of the taro in grams (g) is, 600 g

a) Here, Taro costs $7.00 per kilogram.

Hence, the cost of a taro that weighs 510 grams is,

= 1000 grams = $7.00

510 grams = $7.00 x 510 / 1000

                = $3.57

Hence, the cost of a taro that weighs 510 grams is, $3.57

b) Since, A taro costs $4.20

Now, WE can change the weight of the taro in grams (g) as,

$7.00 = 1000 g

Hence, $4.2 = 1000 x $4.2 / 7

                    = 600 grams

For given equilateral triangle ΔFGH, x = 15. And the measure of each side is 35 units.

In given question,

ΔFGH is equilateral triangle.

The sides of ΔFGH are:

FG = 3x - 10,  

GH =2x + 5 ,

and HF = x + 20 .

We need to find the value of x.

Since ΔFGH is an equilateral triangle, FG = GH = FH

⇒  3x - 10 = 2x + 5 = x + 20

Consider  3x - 10 = 2x + 5

⇒ 3x - 2x = 5 + 10

⇒ x = 15

Now we find the measure of each side.

FG = 3x - 10

FG = 3(15) - 10

FG = 35 units

But FG = GH = FH

So, the measure of each side is 35 units.

Therefore, for given equilateral triangle ΔFGH, x = 15. And the measure of each side is 35 units.

The slope of the line of each pair of points 3/2 , - (1/2) and -(2/3) , 1/3 is zero

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x.

We also refer to this tan as the line's slope.

We know that slope, slope = m =  [tex]\frac{y_2 -y_1}{x_2 -x_1}[/tex]

For the pair of points 3/2 , - (1/2)

m = [tex]\frac{2-2}{-1-3}[/tex]

   = 0/(-4)

Hence the slope is zero for these points.

For the pair of points -(2/3) , 1/3

m = [tex]\frac{3-3}{1-(-2)}[/tex]

   = 0/3

Hence the slope is zero for these points.
