ACTUALLY ANSWER THIS PLEASE An economist wants to compare home ownership in her hometown versus home ownership in the state in which she lives. Statewide, she found that 68% of adults own their home compared to 57% of those surveyed in her city. The median price paid for a home within the state was $148,500 . The median home price paid by survey respondents in the economist’s city was $152,300 . The average number of years a responding city resident has lived in their home is 9 years. In comparison, the average number of years someone in the state has lived in their home is 4 years.

[tex]-\displaystyle\frac{1}{2} :1\frac{3}{4}[/tex]

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

[tex]-\displaystyle\frac{1}{2} :\frac{7}{4}[/tex]

Now turn the fraction you are dividing by over :

[tex]-\displaystyle\frac{1}{2} *\frac{4}{7}[/tex]

Now multiply the numerator of the first fraction times the numerator of the second fraction :

4

Perform the same operation with the denominators :

-4/14

So the result is :

[tex]-\displaystyle\frac{4}{14}[/tex]

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

question a:

What is the probability of flipping two tails?

--> based on the table shown, probabilities of two tails is 1/12. So in 600 trials, the probability of flippng 2 tails is going to be 50, bc 1/12 x 60 = 50.

Given that a fair die is rolled. We know there are six numbers in a fair die.
On rolling a die, the Sample space of the given event E = {1, 2, 3, 4, 5, 6}
Sample space of numbers less than 5 = {1, 2, 3, 4}
Clearly we can see that the number of favorable outcomes = 4
Hence, P(values less than 5) = 4/6 = 2/3.
To find the complement of rolling a number less than 5, we use the formula P' = 1 - P, where P' is the complement of P.
So, let P' be the complement probability of getting numbers less than 5
Now, P'(numbers less than 5) = 1 - P(numbers less than 5)
= 1 - 2/3
= 1/3.
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is 1/3.

Answer:

Step-by-step explanation:

and don't care about handwriting

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)

240 in.2

Answers

Answer:

234 in.2

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

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

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.
