In the figure shown below, if line mis parallel to line n, then find the value of x. (This is a 2 part question.)

m

(2x-10)

(65 - x)

Part A

Write the equation to find the value of x. (DO NOT find x, just write the equation.)

(2x - 10) (65 - x)

Part B

What is the value of x?

Y

**Answer:**

**Step-by-step explanation:**

just add up both alternate internal angles as they are both equal

so, the equation is: 2x-10 = 65-x

**Answer:**

The right equation will be 2x - 10 = 65 - x (you were wrong lol)

**Step-by-step explanation:**

We have: 2x - 10 = 65 - x

=> 2x - 10 + x = 65

=> 3x = 65 + 10 = 75

=> x = 75/3 = 25

Think of a problem that you may be interested in that deals with a comparison of two population means. Propose either a confidence interval or a hypothesis test question that compares these two means. Gather appropriate data and post your problem (without a solution) in the discussion topic. Later, respond to your own post with the solution for others to check their work. For example, you may want to know if the average weight of a rippled potato chip is the same as the average weight of a non-rippled potato chip. You may weigh rippled regular potato chips fro m a large bag and find weights of 1.7,1.9,2.4,1.3, 1.7, and 2.0 grams. You may weigh non-rippled potato chips from another larg bag and find weights of 1.8, 1.6,1.9, 1.9, and 1.4 grams. Assume a random sample was drawn. Think of a problem that you may be interested in that deals with a comparison of two population proportions. Propose either a confidence interval or a hypothesis test question that compares these two proportions. Gather appropriate data and post your problem (without a solution) in the discussion topic. Later, respond to your own post with your own solution. For example, you may believe that the proportion of adults in California who are vegetarians is more than the proportion of adults in New Hampshire who are vegetarians. In two independent polls, you may find that 109 out of 380 California residents are vegetarians and 39 out of 205 New Hampshire residents are vegetarians. For your response to a classmate (two responses required, one in each option), solve your classmate's confidence interval or hypothesis test problem, using a significance level not previously used Make sure that you use appropriate terminology and specify whether you are using the classical method or the p-value method.

Answer:

**Responds to my friend**

**Decision rule **

Fail to reject the null hypothesis

**Conclusion **

There is no sufficient evidence to conclude that the proportion of residents in California who are vegetarians is higher than the proportion in New Hampshire who are vegetarian

Step-by-step explanation:

Here we are going to consider this question

** For example, you may believe that the proportion of adults in California who are vegetarians is more than the proportion of adults in New Hampshire who are vegetarians. In two independent polls, you may find that 109 out of 380 California residents are vegetarians and 39 out of 205 New Hampshire residents are vegetarians.**

** **Here we are going to be solving the hypothesis test problem and we will be making use of the p-value method

From the question the we are told that

The first sample size is [tex]n_1 = 380[/tex]

The second sample size is [tex]n_2 = 205[/tex]

The number of California residents that are vegetarian is [tex]k = 109[/tex]

The number of New Hampshire resident that are veterinarian is [tex]u = 39[/tex]

Generally the sample proportion for California residents is

[tex]\^ p_1 = \frac{k}{n_1}[/tex]

=> [tex]\^ p_1 =\frac{109}{380}[/tex]

=> [tex]\^ p_1 = 0.2868 [/tex]

Generally the sample proportion for New Hampshire residents is

[tex]\^ p_2 = \frac{39}{205}[/tex]

=> [tex]\^ p_2 = 0.1902 [/tex]

The null hypothesis is [tex]H_o : p_1 -p_2 = 0[/tex]

The alternative hypothesis is [tex]H_a : p_1 -p_2 > 0[/tex]

Generally the test statistics is mathematically represented as

[tex]t = \frac{(\^ p_1 - \^ p_2 ) -0}{\sqrt{ \frac{\^ p_1 (1-\^p_1 )}{n_1} + \frac{\^ p_2 (1- \^p_2)}{n_2} } }[/tex]

=> [tex]t = \frac{( 0.2868 - 0.1902) -0}{\sqrt{ \frac{0.2868 (1-0.2868 )}{380} + \frac{0.1902(1- 0.1902)}{205} } }[/tex]

=> [tex]t = 0.036[/tex]

Generally the degree of freedom is mathematically represented as

[tex]df = n_1 + n_2 -2[/tex]

=> [tex]df = 380 + 205 -2[/tex]

=> [tex]df = 583/tex]

Generally the probability of [tex]t = 0.036[/tex] at a degree of freedom of [tex]df = 583/tex] from the t- distribution table is

[tex]p-value = P(t > 0.036) = 0.48564732[/tex]

Let take the level of significance to be [tex]\alpha = 0.05[/tex]

So from the values obtained we see that [tex]p-value > \alpha[/tex] hence the decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to conclude that the proportion of residents in California who are vegetarians is higher than the proportion in New Hampshire who are vegetarian

a stone which is dropped into a dry well hits the bottom in 2.2s how deep is the well. take g=10m/s

**Answer:**

**23.7m**

**Step-by-step explanation:**

Given parameters:

Time taken = 2.2s

Acceleration due to gravity = 10m/s

**Unknown: **

Depth of the well = ?

**Solution: **

To solve this problem, we simply apply one of the motion equations;

S = ut + [tex]\frac{1}{2}[/tex] gt²

where S = depth of the well

u = initial velocity

t = time taken

g = acceleration due to gravity

Input the parameters and solve for S;

Note initial velocity = 0;

S = [tex]\frac{1}{2}[/tex] x 9.8 x 2.2²

** S = 23.7m**

Brandon enters bike race. He bikes 9 1/2 miles every 1/2 hour

Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking. SO here are the data that we need: => 8 and ½ miles = 8.5 miles => ½ hour = .5 hours or 30 minutes Now, let’s solve for the unit rate => SO in every 30 minutes he bikes around 8.5 miles => Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2 => 8.5 * 2 = 17miles => 17 miles / hour

The weekly demand function for x units of a product sold by only one firm is

p = 800 − 0.5x dollars, and the average cost of production and sale is C(with a line on top) = 300 + 2x dollars.

(a) Find the quantity that will maximize profit.

(b) Find the selling price at this optimal quantity.

(c) What is the maximum profit?

**Answer:**

**a**) **x = 798 is the quantity that maximizes the profit**

**b)po(x) = 401 $/unit**

**c)P(max ) = 636105 $**

**Step-by-step explanation:**

**The weekly demand function is equal to the price by unit and the Revenue function is weekly demand times quantity of units then:**

**R(x) = p(x) * x**

**R(x) = ( 800 - 0,5*x ) * x**

**R(x) = 800*x - 0,5*x²**

**The equation for the profit is:**

**P(x) = R(x) - C(x)**

**P(x) = 800*x - 0,5*x² - ( 300 + 2*x)**

**P(x) = 798*x - 0,5*x² - 300**

**a) P(x) = 798*x - 0,5*x² - 300**

**Taking derivatives on both sides of the equation:**

**P´(x) = 798 - x **

**If P´(x) = 0 then 798 - x = 0**

**x = 798 is the quantity that maximizes the profit**

**b) Selling price for the optimal quantity is:**

**p(x) = 800 - 0,5*x**

**p(x) = 800 - 0,5* 798**

**po (x) = 800 - 399**

**po(x) = 401 $/unit**

**c) Pmax = ?**

**P(x) = 798*x - 0,5*x² - 300 by subtitution of x = 798**

**P(max) = 636804 - 399 - 300**

**P(max ) = 636105 $**

a) The **quantity that will maximize profit is **[tex]100 \ units[/tex]**.**

b) The **selling of at this optimal quantity is **[tex]\[/tex][tex]750[/tex]** per unit.**

c) So, **the maximum profit is **[tex]\[/tex][tex]25000[/tex]**.**

A demand function is a** mathematical equation** that **expresses** the **demand for a product or service** as a **function of its price** and other factors such as the **prices of the substitutes** and **complementary goods, income, etc.**

The given demand function,

[tex]P=800-\frac{1}{2}x[/tex]

So, the revenue function is,

[tex]R(x)=p.x\\R(x)=800-x-\frac{1}{2}x^{2}[/tex]

[tex]\Rightarrow[/tex]Average cost is

[tex]\bar{C}=300+2x[/tex]

So, the total cost function is,

[tex]C\left ( x \right )=\bar{C}.x \\ C\left ( x \right )=300x+2x^{2}[/tex]

a) Profit function:

[tex]P\left ( x \right )=R\left ( x \right )-C\left ( x \right ) \\ =800x-\frac{1}{2}x^{2}-300x-2x^{2} \\ P\left ( x \right )=500x-\frac{5}{2}x^{2}[/tex]

For maximum,

[tex]{P}'\left ( x \right )=0 \\ 500\left ( 1 \right )-\frac{5}{2}\left ( 2x \right )=0 \\ 500-5x=0 \\ x=100[/tex]

b) Selling Price:

[tex]P=800-\frac{1}{2}x \\ at \ x=100 \\ P=800-\frac{1}{2}\left ( 100 \right ) \\ =\$ 750[/tex]

c) Maximum Profit:

[tex]P\left ( x \right )=500x-\frac{5}{2}x^{2} \\ P\left ( 100 \right )=500\left ( 100 \right )-\frac{5}{2}\left ( 100 \right )^{2} \\ P\left ( 100 \right )=\$ 25000[/tex]
