y=1/5x−4

y=−1/5x+5/4

y=−5x−4

y=5x+4

**Answer:**

[tex]y' = 5x + 4[/tex]

**Step-by-step explanation:**

**Given**

[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]

**Required**

The inverse relation

[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]

Rewrite as:

[tex]y = \frac{1}{5}x - \frac{4}{5}[/tex]

**Swap x and y**

[tex]x = \frac{1}{5}y - \frac{4}{5}[/tex]

**Multiply through by 5**

[tex]5x = y - 4[/tex]

[tex]y = 5x +4[/tex]

**Rewrite the new function as:**

[tex]y' = 5x + 4[/tex]

**Answer:**

go to omnicalculator.com they have all sorts of calculators including one called a percent changer calculator

**Step-by-step explanation:**

A certain type of legal proceeding has three possible outcomes: in favor of party A, in favor of party B, or not in favor of either party. The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively. A random sample of 40 cases is selected from a certain judge to investigate whether the judgeâs outcomes are consistent with the expected outcomes. A chi-square goodness-of-fit test is conducted, and the value of the chi-square test statistic is Ï2=9.19 with a corresponding pâvalue of 0.01. Assuming the conditions for inference were met, which of the following is the correct interpretation of the pâvalue?

a. There is a 1 percent chance that the company's claim is correct.

b. If the null hypothesis is true, there is a 1 percent chance that the company's claim is correct.

c. If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of 9.19.

d. If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.

e. There is a 1 percent chance of obtaining a chi-square value of at least 9.19.

**The basically **it tells us the **chances **of the claim **being **true

If we **assume **the null **hypothesis **is **correct**.

The Chi-Square Test of Independence determines whether there is an association between categorical variables.

We have given that,

The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively.

If the null **hypothesis** is **true**, there is a 1 **percent chance** that the **company’s **claim is** correct.**

The **p-value** tells us the **likeliness **of our data occurring under the null **hypothesis**.

The ratio of the **wavelength** of the red note and blue note is **2 : 1.**

**Wavelength** is the distance between two consecutive crest and troughs.

Mathematically, we can write** wavelength** as -

λ = c/ν

where -

λ : wavelength

ν : frequency

Given are the two notes as shown in the image.

For the red note, the distance between the consecutive crests is twice to that of the distance between the consecutive crests in case of blue note. We can write the ratio of the **wavelengths** as -

λ(R)/λ(B) = 2/1

Therefore, the ratio of the **wavelength** of the red note and blue note is **2 : 1.**

А Campus athletics is interested in the proportion of registered students living on campus who play basketball recreationally during the semester. They take a random sample of 198 registered students listed as living in campus housing and ask each whether or not they do so. A 95% confidence interval is correctly calculated from this data as (0.12, 0.18). Which of the following is the correct interpretation of this confidence interval ?

a. None of these are correct.

b. We are 95% confident that the proportion of the 198 sampled students that actually play basketball is between 0.12 and 0.18

c. We are 95% confident that, among the population of students that play basketball recreationally, the proportion who live on campus is between 0.12 and 0.18.

d. The sample proportion of on-campus students that play basketball will be between 0.12 and 0.18 in 95% of samples of size 198

**Answer:**

**c. We are 95% confident that, among the population of students that play basketball recreationally, the proportion who live on campus is between 0.12 and 0.18.**

**Step-by-step explanation:**

According to the question, it is mentioned that there is 95% confidence interval and it is calculated (0.12,0.18)

So the correct interpretation is that they are 95% confident that the students who play basketballs the proportion should lies between 0.12 and 0.12

So, the option C is correct

Find the ratio of the areas.

9514 1404 393

**Answer:**

3 -2√2

**Step-by-step explanation:**

For a regular octagon of side length s, the "flat-to-flat" dimension across the center is s(1+√2). The flat-to-flat dimension of the shaded center octagon is simply s. The ratio of areas is the square of the ratio of linear dimensions, so we have ...

small area / large area = (1/(1+√2))^2 = 1/(3+2√2)

small area/large area = **3 -2√2**

_____

The attachment shows octagons after the fashion described here. The side length of the larger one is 2 units. The numbers inside are the areas. They have the ratio shown above.

F(x)=8x sqrt(x-x^2) Find the exact maximum

First take note of the domain of *f(x)* ; the square root term is defined as long as *x* - *x* ² ≥ 0, or 0 ≤ *x* ≤ 1.

Check the value of *f(x)* at these endpoints:

*f* (0) = 0

*f* (1) = 0

Take the derivative of *f(x)* :

[tex]f(x)=8x\sqrt{x-x^2}=8x\left(x-x^2\right)^{\frac12}[/tex]

[tex]\implies f'(x)=8\left(x-x^2\right)^{\frac12}+4x\left(x-x^2\right)^{-\frac12}(1-2x)=4\left(x-x^2\right)^{-\frac12}\left(2\left(x-x^2)\right)+x(1-2x)\right)=\dfrac{4(3x-4x^2)}{\sqrt{x-x^2}}[/tex]

For *x* ≠ 0, we can eliminate the √*x* term in the denominator:

[tex]x\neq0\implies f'(x)=\dfrac{4\sqrt x (3-4x)}{\sqrt{1-x}}[/tex]

*f(x)* has critical points where *f '(x)* is zero or undefined. We know about the undefined case, which occurs at the boundary of the domain of *f(x)*. Check where *f '(x)* = 0 :

√*x* (3 - 4*x*) = 0

√*x* = 0 or 3 - 4*x* = 0

The first case gives *x* = 0, which we ignore. The second leaves us with *x* = 3/4, at which point we get a maximum of **max{***f(x) ***} = 3√3 / 2**.

Let f(x) = cxe−x2 if x ≥ 0 and f(x) = 0 if x < 0.

(a) For what value of c is f a probability density function?

(b) For that value of c, find P(1 < X < 3).

(a) If *f(x)* is to be a proper density function, then its integral over the given support must evaulate to 1:

[tex]\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx = \int_0^\infty cxe^{-x^2}\,\mathrm dx=1[/tex]

For the integral, substitute *u* = *x* ² and d*u* = 2*x* d*x*. Then as *x* → 0, *u* → 0; as *x* → ∞, *u* → ∞:

[tex]\displaystyle\frac12\int_0^\infty ce^{-u}\,\mathrm du=\frac c2\left(\lim_{u\to\infty}(-e^{-u})-(-1)\right)=1[/tex]

which reduces to

*c* / 2 (0 + 1) = 1 → *c*** = 2**

(b) Find the probability P(1 < *X *< 3) by integrating the density function over [1, 3] (I'll omit the steps because it's the same process as in (a)):

[tex]\displaystyle\int_1^3 2xe^{-x^2}\,\mathrm dx = \boxed{\frac{e^8-1}{e^9}} \approx 0.3678[/tex]
