Answer:

16 dollars

Step-by-step explanation:

The price includes the price of an empty bag B and the price of popcorn that is proportional to x (the number of ounces). Let each popcorn cost A$. Then the price of bag y = Ax + B

Given x = 10, y = 6, so 6 = 10A + B    (1)

Given x = 20, y = 8, so 8 = 20x + B   (2)

(2) - (1): 2 = 10A, so A = 2/10 = 0.2

Sub it into (1), 6 = 10*0.2 + B = 2 + B, so B = 6 - 2 = 4

We got y = 0.2x + 4

Check: x = 35, y = 0.2*35 + 4 = 11 (right)

x = 48, y = 0.2*48 + 4 = 13.6 (right)

Now find y when x = 60

y = 0.2*60 + 4 = 16 dollars

Step-by-step explanation:

(2)(4)+(11)(3)+(13)(2)+2x−8=x+4

Simplify both sides of the equation.

8+33+26+2x+−8=x+4

Combine like terms

(2x)+(8+33+26+−8)=x+4

2x+59=x+4

2x+59=x+4

Subtract from both sides

2x+59−x=x+4−x

x+59=4

Subtract 59 from both sides

x+59−59=4−59

The average value of f(x) over [2, 6] is given by the definite integral,

[tex]\displaystyle f_{\rm ave[2,6]} = \frac1{6-2} \int_2^6 3\ln(2+x^3)\cos(x) \, dx[/tex]

and is approximately -1.67284.

The approximate average value of the function in the closed interval [2,6] is -1.628.

It is given that the f is the function given by:  [tex]\rm f(x) = 3ln(2+x^2)cosx[/tex]

It is required to find the average value of f in the closed interval [2,6]

It is defined as the mathematical approach to calculating the smaller parts or components.

We have function f:

[tex]\rm f(x) = 3ln(2+x^2)cosx[/tex]

For the average value in [2,6]

We integrate the function with lower limit 2 and higher limit 6.

[tex]\rm \int_{2}^{6}f(x) =\int_{2}^{6}( 3ln(2+x^2)cosx)\\[/tex]

The average value of the above function:

[tex]\rm =\frac{1}{6-2} \int_{2}^{6}( 3ln(2+x^2)cosx)\\[/tex]

Further solving:

[tex]\rm =\frac{3}{4} \int_{2}^{6}( ln(2+x^2)cosx)\\[/tex]

Further solving and applying limits we get:

[tex]=\frac{3}{4}\times-2.2304[/tex]

= -1.628

Thus, the approximate value of the function in the closed interval [2,6]

is -1.628.

Answer:

y > 4x + 1.

Step-by-step explanation:

The other person that listed their answer was also correct.

In order to make an equation as such, we need to find the slope of this line and the y-intercept. The y-intercept is the "+b" in y=mx+b. The slope is mx. So, to identify the slope we need to calculate rise over run on the graph, which is 4. So:

y __ 4x + __.

On the y-intercept, the y crosses and meets at the point (0,1) on the x-intercept exactly, so we don't need to worry about there being any fractions right now. So:

y __ 4x + 1.

Now, because this line has a positive slope, the inequality symbol is "chomping" at the y, like this:

y > 4x + 1.

I hope that this helps.

The answer in the form y = mx + b, using the appropriate inequality symbol in place of the equal sign is y = -2x + 3

The inequality symbol is less than (<). This means that all points below the line y = -2x + 3 satisfy the inequality.

To understand why this is the case, let's consider a few points on the line y = -2x + 3. For example, the point (0, 3) is on the line. If we plug these coordinates into the inequality, we get:

y = -2x + 3

3 = -2(0) + 3

3 = 3

This is a true statement, so we know that the point (0, 3) satisfies the inequality.

Now, let's consider a point that is below the line y = -2x + 3. For example, the point (1, 1) is below the line. If we plug these coordinates into the inequality, we get:

y = -2x + 3

1 = -2(1) + 3

1 = 1

This is also a true statement, so we know that the point (1, 1) satisfies the inequality.

Therefore, we can conclude that all points below the line y = -2x + 3 satisfy the inequality y < -2x + 3.

Here is a graph of the inequality y < -2x + 3.

As you can see from the graph, all points below the line y = -2x + 3 satisfy the inequality y < -2x + 3.

Step-by-step explanation:

The PDF for the wait time (denoted by the random variable X) is

[tex]f_X(x) = \begin{cases}\lambda e^{-\lambda x} & \text{if }x \ge 0 \\ 0 &\text{otherwise}\end{cases}[/tex]

where λ = 1/75. We want to find Pr[X > 70 | X ≥ 40]. Pierre has already been waiting for 40 min, so if he waits another 30 min he will have waited for a total of 70 min.

By definition of conditional probability,

Pr[X > 70 | X ≥ 40] = Pr[X > 70 and X ≥ 40] / Pr[X ≥ 40]

If X > 70, then automatically X ≥ 40 is satisified, so the right side reduces to

Pr[X > 70 | X ≥ 40] = Pr[X > 70] / Pr[X ≥ 40]

Use the PDF or CDF to find the remaining probabilities. For instance, using the PDF,

[tex]\mathrm{Pr}[X > 70] = \displaystyle \int_{-\infty}^{70} f_X(x) \, dx = \int_0^{70} f_X(x) \, dx \approx 0.3932[/tex]

Or, using the CDF,

[tex]F_X(x) = \displaystyle \int_{-\infty}^x f_X(t) \, dt = \begin{cases}0&\text{if }x<0 \\ 1-e^{-\lambda x} & \text{if }x \ge 0\end{cases}[/tex]

[tex]\implies \mathrm{Pr}[X > 70] = 1 - \mathrm{Pr}[X \le 70] = 1 - F_X(70) \approx 0.3932[/tex]

Similarly, you'll find that Pr[X ≥ 40] ≈ 0.5866.

It follows that

Pr[X > 70 | X ≥ 40] ≈ 0.3932 / 0.5866 ≈ 0.6703

The given equation is:

y = 1/2x

The equation is of the form:

y  =  mx  +  c

where m represents the slope

and c represents the y-intercept

Comparing the equation y = 1/2x  with y = mx + c
