On a demand curve for most goods, as the price of the product decreases, the number of units the customer is willing to buy increases.

The relationship between price and quantity demanded is a fundamental concept in economics and is typically represented by a demand curve. According to the law of demand, as the price of a product decreases, the quantity demanded by customers tends to increase, and vice versa. This inverse relationship between price and quantity demanded can be attributed to various factors.

When the price of a product decreases, it becomes more affordable for consumers, leading to an increase in their willingness to purchase it. Lower prices may also create a perception of greater value or incentivize customers to buy more of the product. Conversely, as the price of a product increases, consumers may find it less affordable or less attractive, resulting in a decrease in their willingness to buy.

The chi-square test of independence is typically used to analyze the relationship between two variables when both variables are nominal, the two variables have been measured on different individuals and the observations on each variable are within-subjects in nature. The answer is  D. all of the above

The chi-square test of independence is a statistical test that is used to determine if there is a significant association between two categorical variables. It is commonly used when both variables are nominal, meaning they consist of categories or groups rather than numerical values.

When conducting the chi-square test of independence, the data is typically collected by measuring the two variables on different individuals or units.

For example, researchers may collect data on the gender (nominal variable) and political affiliation (nominal variable) of different individuals and analyze whether there is a relationship between the two variables.

The test examines the observed frequencies of the different categories in a contingency table and compares them to the expected frequencies under the assumption of independence. If the observed and expected frequencies significantly differ, it suggests that there is an association between the two variables.

Therefore, the chi-square test of independence is applicable when both variables are nominal and the data is collected on different individuals. This allows researchers to investigate the relationship between the variables and determine if they are associated or independent.

The sum of an infinite geometric series is given by a+ar+ar^2  where a is the first term and r is the common ratio.

The sum of the series  can be represented by :

a / ( 1 - r)  = 12

a = 12 ( 1- r )    (1)

So....note that the sum of the  terms  with odd powers of r  can be represented by :

ar  + ar^3  + ar^5 + ar^7 +  ..... + ar^(2n - 1)  =  5   (2)

And note that the sum of the  terms  with even powers of r  can be represented by :

a  +  ar^2  + ar^4 + ar^6 + ar^8 +  ..... + ar^(2n)  =  7   (3)

Multiply (2)  by r on both sides

ar^2  + ar^4  + ar^6 + ar^8 +  ..... + ar^(2n )  =  5r     (4)

Subtract   (4)  from (3)

a  = 7 - 5r    (5)

Sub (5)  into (1)

7 - 5r  = 12(1 - r)

7 - 5r  =  12 - 12r

7r = 5     →   r  =  5/7

Check

a = 7 - 5(5/7)  =  24/7

a / ( 1 - r)  =

Answer: (I worked left-right instead of column 1, then column 2. That's why the answers are jumbled up. 2 on my work corresponds to 4 in the pic, 3 corresponds to 2, 4 corresponds to 5, and 5 corresponds to 3.)

1. 75 degrees

2. 112 degrees

3. 89 degrees

4. x is 8, so 111 degrees

5. x is 3 in both cases, so 90 degrees each

6. x is -7, so 130 degrees

Step-by-step explanation:

1. Adjacent angles are the same measurement. Since the one labeled is 75 degrees, and the question marked angle is adjacent, it is also 75 degrees.

2. The angles shown are complementary, so they both equal 180 degrees. To find the angle marked with "?", subtract 68 from 180 for 112 degrees.

3. The angle labeled is 89 degrees. The one labeled with "?" should be the same, as it is below it, and on the same point as the labeled one. So, 89 degrees is the measurement.

4. The labeled angle is 69 degrees. 180 - 69 is 111 degrees. The equation shown now becomes 12x + 15 = 111. 111 - 15 is 96, which means 12x = 96. Divide both sides by 12 to get x equalling 8.

5. These lines are all perpendicular, so they're all 90 degrees. 29x + 3 = 90, and 31x - 3 = 90 are the new equations. I will attempt x as 3, to see if it's a true value. 29(3) is 87, and 87 + 3 is 90, so 3 is true there. 31(3) is 93, and 93 - 3 is also 90. So x is 3 in both cases

6. We already know one of the angles is 50 degrees. These are complementary, so subtract 50 from 180 to get 130 degrees. So, the equation is x + 137 = 130, which then becomes, 137 + -x = 130. 137 minus 30 is 7, so x is -7.

Answer:

1.) 75°

2.) 89°

3.) 90°  x = 3

4.) 112°

5.) 111°   x = 8

6.) 130°  x = -7

Step-by-step explanation:

1.) They are vertical so they measure the same

2.) They are corresponding angles so they equal the same

3.) They should equal up to 180.

29x + 3 = 31x - 3 (subtract 29x on both sides)

3 = 2x - 3 (add 3 on both sides)

6 = 2x (divide by 2 on both sides)

3 = x Plug in. 29(3) + 3 = 90 Both angles equal 90 degrees

4.) They should equal up to 180. 180 - 68 = 112

5.) They should equal up to 180. They are same side interior angles.                                                                             69 + 12x + 15 = 180 (collect like terms)

84 + 12x = 180 (subtract 84 on both sides)

12x = 96 (divide by 12 on both sides)

x = 8 Plug in 12(8) + 15 = 111 degrees

6.) They should equal up to 180.

x + 137 + 50 = 180 (collect like terms)

x + 187 = 180 (subtract 187 on both sides)

x = -7 Plug in -7 + 137 + 50 = 180 (collect like terms) 180= 180

Given:

BG = 27

AG = 13 + 7x

Note that when three perpendicular bisectors of the sides of a triangle meet at a point, the point is called a Circumcenter.

Also, note that the Circumcenter is equidistant from the vertices of the triangle.

So for the given triangle, G is the circumcenter, and AG = BG = CG.

Let's go ahead and solve for x as seen below;

Let's subtract 13 from both sides of the equation, we'll have;

Let's divide both sides by 7;

Answer:

First lets find the area of the bottom circle:

7.2 is your radius so:

7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.

lets continue:

51.84 x 3.14(pi) = 162.7776

Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.

2 x 3.14 x 7.2 = 45.216

Now lets multiply it by the height:

45.216 x 17 = 768.672

Now lets add both areas:

768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.

The quantity or complete absence of the thing being measured is represented by the zero point.

Ex. Because the zero point is set arbitrarily and does not indicate the complete absence of temperature, the Fahrenheit scale is an interval scale.

Zero degrees on either scale is not a "true" zero because it is an arbitrary number. The absence of temperature does not occur at the zero point; It's just a random number on the scale. Other examples of common interval scales include: Age and SAT scores (one is culturally determined).

In addition, on a ratio scale, the distance between two variables is also the same. Furthermore, a proportion scale has a genuine zero point, meaning the worth of zero isn't erratic.

It is estimated that many first-year college students gain 7-8 pounds. Students are more likely to gain weight during their first year of college than at any other time in their life. Many college students are known for gaining the infamous “freshman 15,” or the 15 pounds many students pack on during their first year of college.

However, studies show that the actual weight gain is often less than this estimate, with many first-year college students gaining around 7-8 pounds. The causes of this weight gain are multifaceted, and may include changes in dietary habits, increased alcohol consumption, stress, lack of exercise, and lack of sleep. College students are often faced with a variety of new experiences and responsibilities, which can make it difficult to prioritize healthy habits and maintain a healthy lifestyle.

For example, college students may find themselves eating more fast food or dining hall meals than they did at home, which can be high in calories and low in nutritional value. They may also have less time to exercise or get enough sleep, which can contribute to weight gain.In addition, college students are often exposed to high levels of stress, which can cause them to turn to food for comfort. This stress may be caused by academic pressures, social challenges, or financial difficulties. Finally, college students may find themselves drinking more alcohol than they did in high school, which can be high in calories and contribute to weight gain.While the freshman 15 may be a bit of a myth, there is no denying that many college students struggle with weight gain during their first year of college. By prioritizing healthy habits and making small changes to their lifestyle, students can maintain a healthy weight and avoid the weight gain often associated with college life.

She can only move a certain distance in three seconds, with a lower distance of 33.45 feet and a upper distance of 43.45 feet.

The first three seconds of a race saw a runner's speed rapidly grow.

The time is therefore 3 seconds.

The table provides her speed at half-second intervals.

We are aware,

Speed = Distance / Time

Similarly

Distance = Speed × Time

t equals 0.5 seconds

Then, the lower distance traveled overall is equal to 0.5(0 + 6.7 + 9.2 + 14.1 + 17.5 + 19.4).

Terms are multiplied and added.

= 0.5 × 66.9

= 33.45 feet

The upper distance traveled is equal to 0.5 (6.7 + 9.2 + 14.1 + 17.5 + 19.4 + 20)

= 0.5 × 86.9

= 43.45 feet

As a result, Her lower distance in three seconds is therefore 33.45 feet, and her upper distance in three seconds is 43.45 feet.
