can someone find the equation plz and solve it.



i will give brainliest i need u guys to save my math grade lol :(

Given:

The scatter plot and trend line.

To find:

Type of association, slope, equation of trend line and average cost of apple per pound.

Solution:

Form the given graph it is clear that the trend line passes through the two points (0,0) and (12,24).

Slope of trend line is

[tex]m=\dfrac{24-0}{12-0}[/tex]

[tex]m=\dfrac{24}{12}[/tex]

[tex]m=2[/tex]

Slope of trend line is positive. It means, it represents positive correlation.

So, the type of association of the scatter plot is positive association.

Therefore, the slope of trend line is 2.

The trend line passes through (0,0) have slope 2, so the equation of the trend line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-0=2(x-0)[/tex]

[tex]y=2x[/tex]

Therefore, the equation of trend line is [tex]y=2x[/tex].

Slope of the line is 2.

Therefore, the average cost of apples per pound is $2.

so if the diamteter is 7, then the circumference is

[tex]7\pi[/tex] or if you are told to round to the nearest hundredth or thousandth, multiply pi in as 3.1415 to get that the circumference is 21.9905 cm

Answer:

A and B

Step-by-step explanation:

Given

List of given options

Required

Which will correctly take 3 to fill the blank

Represent the blanks with x

Option A:

[tex]x : 4 = 12 : 16[/tex]

Convert to fractions

[tex]\frac{x}{4} = \frac{12}{16}[/tex]

Multiply through by 4

[tex]4 * \frac{x}{4} = 4 * \frac{12}{16}[/tex]

[tex]x = \frac{48}{16}[/tex]

[tex]x = 3[/tex]

Option B:

[tex]1 : 5= x : 15[/tex]

Convert to fraction;

[tex]\frac{1}{5} = \frac{x}{15}[/tex]

Multiply through by 15

[tex]15 * \frac{1}{5} = \frac{x}{15} * 15[/tex]

[tex]15 * \frac{1}{5} = x[/tex]

[tex]3 = x[/tex]

[tex]x = 3[/tex]

Option C:

[tex]x : 1 = 12 : 3[/tex]

Convert to fraction

[tex]\frac{x}{1} = \frac{12}{3}[/tex]

[tex]x = 4[/tex]

Option D

[tex]15:x = 3:1[/tex]

Convert to fraction

[tex]\frac{15}{x} = \frac{3}{1}[/tex]

Cross Multiply

[tex]3 * x = 15 * 1[/tex]

[tex]3 * x = 15[/tex]

Divide through by 3

[tex]x = 5[/tex]

From the above calculations.

Option A and B can be filled with 3

Answer:

y = 17(7) + 6

Step-by-step explanation:

Given that:

Amount owed = $125

Payment per week = $7

Number of whole weeks to pay :

$125 / $7 = 17.85 = 17 whole weeks

$125 - (17 * 7) = $125 - $119 = $6

Using slope intercept notation :

y = mx + c

Where m = slope ; c = intercept. ;

m = 17,; x = $7, c = $6

y = 17(7) + 6

Answer:

$1.40

Step-by-step explanation:

if the total is $1.80 and the hot cocoa costs exactly $1 more the cookie has to be $0.40 otherwise the price would go above or below the total when it is doubled with another dollar added

A cup of hot cocoa costs is $0.40.

Given that,

At a holiday market, the total cost for a cup of hot cocoa and a cookie is $1.80.

If a cup of hot cocoa costs one dollar more than a cookie,

We have to determine,

How much does a cup of hot cocoa cost?

According to the question,

At a holiday market, the total cost for a cup of hot cocoa and a cookie is $1.80.

If a cup of hot cocoa costs one dollar more than a cookie,

The total is $1.80 and the hot cocoa costs exactly $1 more the cookie has to be $0.40

The price would go above or below the total when it is doubled with another dollar added.

Hence, A cup of hot cocoa costs is $0.40.

Answer:

35, 35, and 50

Step-by-step explanation:

50 + x + x = n

n ÷ 3 = 40

n = 40 x 3

n = 120

50 + 2x = n

50 + 2x = 120

2x = 120 - 50

2x = 70

2x/2 = 70/2

x = 35

To check:

35 + 35 + 50 = 120

120 ÷ 3 = 40

Hope this helps

Answer:

35

Step-by-step explanation:

let us take each boy's weight as x

therefore,

average = [tex]\frac{x+x+50}{3\\}[/tex]

40 = [tex]\frac{x+x+50}{3\\}[/tex]

40 x 3 = x + x + 50

120 - 50 = 2x

70 = 2x

2x = 70

x = [tex]\frac{70}{2}[/tex]

x = 35

So weight of each boys is 35.

Answer:

5.38 ounces

Step-by-step explanation:

Given that :

Alice height = 1 mile

Distance of earth to moon = 239000 miles

Number of base 10 cakes required so they Alice's head just touches the moon ;

Using the relation :

Distance = height per ounce * 10^number of ounces

Height per ounce = 1 mile ;

Let number of ounces = n

Hence,

239000 = 1 * 10^n

239000 = 10^n

Take log of both sides

Log(239000) = n

5.3783979 = n

5.3784 = n

Hence, Alice should take 5.38 ounces of base 10 cakes

Complete question is;

Arrange the systems of equations that have a single solution in Increasing order of the x-values in their solutions.

1) 2x + y = 10

x - 3y = -2

2) x + 2y = 5

2x + y = 4

3) x + 3y = 5

6x - y = 11

4) 2x + y = 10

-6x - 3y = -2

Answer:

Arranging the systems in increasing value of x gives;

System 2, system 3, system 1

Step-by-step explanation:

1) 2x + y = 10 - - - (eq 1)

x - 3y = -2 - - - (eq 2)

Multiply eq 1 by 3 to get;

6x + 3y = 30

Add it to eq 2 to get;

7x = 28

x = 28/7

x = 4

2) x + 2y = 5 - - - (eq 1)

2x + y = 4 - - - (eq 2)

Multiply eq 2 by 2 to get;

4x + 2y = 8

Subtract eq 1 from it to get;

3x = 3

x = 3/3

x = 1

3) x + 3y = 5 - - - (eq 1)

6x - y = 11 - - - (eq 2)

Multiply eq 2 by 3 to get;

18x - 3y = 33

Add to eq(1) to get;

19x = 38

x = 38/19

x = 2

4) 2x + y = 10 - - - (eq 1)

-6x - 3y = -2 - - - (eq 2)

Make y the subject in eq 1 to get;

y = 10 - 2x

Put in eq (2);

-6x - 3(10 - 2x) = -2

-6x - 30 + 6x = -2

0 = 0

Thus,no solution exists.

Arranging the systems in increasing value of x gives;

System 2, system 3, system 1

Answer:

9 cm

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of all the sides of the polygon.

If a polygon is a triangle, and its 3 sides have length a, b, and c, then the perimeter is the sum of a, b,, and c.

perimeter = a + b + c

Here, the perimeter = 29 cm

The lengths of the sides are a = 8 cm, b = 12 cm, c = x.

8 + 12 + x = 29

x + 20 = 29

x = 9

Answer: 9 cm

Answer:

463mi

Step-by-step explanation:

Answer:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

16 / 20 = 0.800

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 800

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 16/20 (or 0.800) rounded to the nearest hundredth in decimal format is:

0.80

Next, we will make 16/20 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:

0.80 = 0.80/1

Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:

(0.80 x 100) / (1 x 100) = 80/100

That's it. 16/20 rounded to the nearest hundredth is displayed below (simplified if necessary):

1. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.

Area = Length X breadth = 6m X 5.1 m =30.6 metre square

2. Kite: it has two equal pairs of sides adjacent to each other

Area =(BD X CE )/2 = (8 X 12) /2 = 48

3. Parallelogram: This is because it has two opposite sides that are parallel, and the angles are not 90 degrees.

Area = base X height = 5.7 X 8 = 45.6 metres square

4. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.

Area = Length X breadth = 2 yd X 3.1 yd = 6.2 square yards

5. Trapezium: it has only one pair of sides parallel.

Area = 0.5 ( top side + bottom side ) X height = 0.5 (6+3 X 5) = 22.5

6. Kite: it has two equal pairs of sides adjacent to each other

Area =(EG X FH)/2 = (10 X 7) /2 = 35
