Answer:

14 - 9x + 12 + x

This is an expression (not an equation), therefore it can't be solved.

Factor the expression

Collect like terms:

⇒ 14 + 12 - 9x + x

Combine like terms:

⇒ -8x + 26

Find the highest common factor of 26 and 8

Factors of 26: 1, 2, 13, 26Factors of 8: 1, 2, 4, 8

Therefore, the highest common factor is 2

Factor out -2 from -8x + 26:

⇒ -2(4x + 13)

Alternatively, factor out 2 from 26 - 8x:

⇒ 2(13 - 4x)

Four spinners with distinct sections of equal area are spun 40 times. Which spinner is most likely to produce actual results closest to the predicted results?

Answers

Answer

: a spinner with 2 sections

Step-by-step explanation:

It is given that , Four spinners with distinct sections of equal area are spun 40 times.We want, theoretical Probability should be equal to experimental probability.The Spinner with least Division and maximum number of Spun will produce result equivalent to Theoretical probability.Here , in the problem there are four spinners, one having 2 cross sections, second having 5 cross sections, third having 8 section, and fourth having 10 section.So, Minimum number of Section is in Spinner A , which is equal to 2, probability of each section being equal to , Spinner having 5 cross sections,probability of each section being equal to ,third spinner, having 8 section,probability of each section being equal to ,fourth spinner having 10 section, probability of each section being equal to ,.To get the result that is experimental probability equal to theoretical probability, the number of trials should be as large as possible to get the result equal to theoretical probability.

A. A spinner with 2 sections

A figure is translated by (x,y) ---> (x+3,y-4) then by (x,y) ---> (x -3,y+4). Without graphing, how do you know the final position of the figure? Write an argument that can be used to defend your solution.

Answers

Answer:

the figure is in its original spot

Step-by-step explanation:

when u first translated the figure, the rule was (x+3,y-4), so it goes up by 3 units and left by 4 units. The next translation was the exact opposite of what u just did. It went down 3 units, and right by 4 units. By doing the exact opposite, u ended up on the original spot before anything was done to it

How to find the Distribution of data?

Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test.

For skewed distributions, it is quite common to have one tail of the distribution considerably longer or drawn out relative to the other tail.

As, it is known that, when the distribution of data is left-skewed, the mean is less than median.

In any research of distribution, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.

The distribution can be described by its center. If the distribution is skewed left or right, the median is an accurate measure of center.

The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.

Unit rate is same as slope - change in Y over change in X
Y 2.00- .40 = 1.60

You can double check your work, .20 x 20 oz = 4.00 as shown in last column

Step-by-step explanation:

To find the area of the composite figure divide it into 3 shapes.

A large rectangle which is 10 by 20 so the area is 200.

A smaller rectangle which is 2 by 14 so the area is 28.

Finally, a small triangle which is 2 by 6 so the area is 6.

Add the areas together and the total area is 200 + 28 + 6 = 234.

Andre makes a trip to Mexico. He exchanges some dollars for pesos at a rate of 20 pesos per dollar. While in Mexico, he spends 9000 pesos. When he returns, he exchanges his pesos for dollars (still at 20 pesos per dollar). He gets back the amount he started with. Find how many dollars Andre exchanged for pesos and explain your reasoning. If you get stuck, try writing an equation representing Andre’s trip using a variable for the number of dollars he exchanged

Also is it possible if you could make it so I can copy and paste? I don't have much time left.

Answers

The answer is $450

If 20 pesos = $1, simply divide 9000 by 20 to get 450

Or do my way and divide 9000 by 10 to get 900 then divide by 2 to get 450

So the answer is $450

What is the mean for Doctor A’s data set on contacts? What is the mean for Doctor B’s data set on contacts? Write a sentence comparing the number of people who wear contacts in the two data sets.

Answers

Answer:

The mean for Doctor A's set of contacts is 107.7 and the mean for Doctor B's set of contacts is 118.6. I'll let you do the rest :)

A little reminder about mean: mean is when you add up all the numbers then divide by how many numbers there are, hoped this helped (*^▽^*)

Answer: Doctor A's set of contacts is 107.7 and the Mean for Doctor B's set of contacts is 118.6.

Step-By-Step Explanation: Upon further examination of the data sets, it is interesting to note that the age groups represented in the first and second sets differ significantly. The first set had a higher percentage of individuals aged 40 and above, while the second set had a higher percentage of individuals aged 20-30. This information could provide valuable insights into age-related trends in eye care practices and could potentially lead to the development of more targeted treatment options for different age groups.

Furthermore, it is important to consider other factors that may influence the wearing of contact lenses, such as geographical location and occupation. It would be interesting to analyze data sets from different regions and industries to identify any patterns or trends that may emerge.

In conclusion, the analysis of data sets related to eye care practices can provide valuable insights into different aspects of our lives. It is essential to continue exploring and analyzing such information to make informed decisions and improve the quality of eye care for those who wear contact lenses.
