​

Answer:

[tex] y = \frac{3}{2}x [/tex]

Step-by-step explanation:

The graph shows there is a proportional relationship between amount of grams of fish (x) and number of calories (y).

A original relationship can be represented by An equation as [tex] y = kx [/tex], where, k = constant of proportionality (y/x).

The constant of proportionality using any point, let's say (200, 300), would be:

k = y/x = 300/200 = ³/2

Plug in the value of k into [tex] y = kx [/tex].

Thus, the equation that reflects the relationship would be:

[tex] y = \frac{3}{2}x [/tex]

The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x) and this can be determined by using the point-slope form of a line.

Given :

The point-slope form can be used to determine the equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories.

The point-slope form is given by the equation:

[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]     ----- (1)

where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.

Now, put the values of [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the equation (1).

[tex]\dfrac{y-150}{x-100}=\dfrac{300-150}{200-100}[/tex]

[tex]2(y-150)=3(x-100)[/tex]

2y - 300 = 3x - 300

2y - 3x = 0

2y = 3x

The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x).

y=-1/3x + 2/3

Answer:

-1.961666666666

Step-by-step explanation:

The highest level of PEMDAS here is multiplication/division which is done left to right. So do 11/12 first.

11/12 (-2.4)

.916 (-2.4)

Then multiply to get an answer of -1.961666666 ( the six repeats forever)

Answer:

20%

Step-by-step explanation

let's assume 100% = 2300

x% = 460

100% / x% = 2300/460

460x100/2300 = 20

the answer is 20%

Answer:

The survey shows that 20% of the individuals were satisfied with the car.

Step-by-step explanation:

When we need to find the percentage of a population, we can use the following formula:

We need to identify the part and the whole in this problem.

We are given that 2,300 people are surveyed, so this is the whole portion.

We are also given that 460 were satisfied, so this is the part portion.

Therefore, we can set up our fraction.

Now, let's solve the percentage.

[tex]\displaystyle \frac{460}{2300} \times 100\\\\\frac{2}{100} \times 100 = 20\%[/tex]

Therefore, of those surveyed, 20% of the individuals were satisfied with the car.

Answer:

[tex]SE_p = 0.055[/tex]

Step-by-step explanation:

Given

[tex]n = 79[/tex] --- Heads

Proportion, p = 46 out of 79

Required

Determine the standard error for sample proportion (SEp)

This is calculated using the following formula

[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this case:

[tex]p = \frac{46}{79}[/tex]

[tex]p = 0.5823[/tex]

Substitute values for p and n in:

[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * (1-0.5823)}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * 0.4177}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.24322671}{79}}[/tex]

[tex]SE_p = \sqrt{0.00307881911}[/tex]

[tex]SE_p = 0.0554871076[/tex]

[tex]SE_p = 0.055[/tex] ---- Approximated

[tex] \frac{ {7x}^{2} - 5x + 1}{4x + 1} [/tex]

Step-by-step explanation:

Since the denominators are the same we just have to combine the top.

[tex] {x}^{2} - 5x + {6x}^{2} + 1[/tex]

Combine alike terms.

[tex] {7x}^{2} - 5x + 1[/tex]

put that over our denominator.

Answer:

137.3

Step-by-step explanation:

Answer:

He originally spent 120$

He made 12 extra dollars.

Step-by-step explanation:

To solve this I turned the 110% into a decimal.

So I divided 110 by 100 and got 1.1

In order to find the original number you would then need to divide the total cost of the bicycle and helmet together by 1.1

So, 116 + 16 = 132

132/1.1= 120

Answer:

-13

Step-by-step explanation:

You need to separate the 8 from each side of the equation. Picture it like this:

-104= 8 (multiplied by) x

To separate 8 from the variable, you need to divide that side by 8. Similarly, you need to do the same thing to the other side.

-104/8=8x/8

-13=x
