Dirk just failed the driving portion of his driver’s license exam. dirk will most likely explain his failure by saying that he could not see well because it was raining. does not have good spatial or navigational skills. did not practice driving enough. did not study the driver’s manual very well.


Answer:

Americans will pay more for goods produced in Mexico in 2011.

Explanation:

This is a situation of devaluation of the dollar in relation to the Mexican peso. If in 2009 the dollar was worth 16 pesos, but in 2011 it is 14, it means that the purchasing power of the dollar in relation to the Mexican peso has decreased, although it is still high.

In that case, for an American to buy products produced in Mexico in 2011, he or she will spend a little more dollars than he or she would spend in 2009. This is common, since the currencies fluctuate according to the financial market . Thus, the dollar can be valued or devalued, as happened in this example.

If, for example, in 2015 the dollar will buy 20 pesos, it will mean that the dollar appreciated in relation to the peso, increasing the purchasing power of Americans for Mexican products.

Find the mean, median, and mode of the data set. round to the nearest tenth. test scores on a math exam: 88,89,65,62,83,63,84,63,74,64,71,82,66,88,79,60,86,63,93,99,60,85 a. mean = 69.5, median = 76.5, mode = 63 b. mean = 75.8, median = 89.5, mode = 6 c. mean = 75.8, median =76.5, mode = 63 d. mean = 69.5, median = 76.5, mode = 79.5


Answer:

The correct options are:

  • Four families said they ate out twice the previous week.
  • One family said they ate out 5 times the previous week.
  • The median best represents the data set.

Step-by-step explanation:

We are given a data set as:

4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1

On arranging this data set in the frequency table we get:

Number of times they went for dinner    Number of families  

           0                                                          2

           1                                                           3

           2                                                          4

           3                                                           1

           4                                                           2

           5                                                           1

           6                                                            1

  • Hence, the range of the number line is between 0 to 6.
  • Also there are 4 dots above 2.

    Hence,  Four families said they ate out twice the previous week.

  • Also there is one dot above 5.

        Hence,  One family said they ate out 5 times the previous week.

  • The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.

Hence, the data set is not symmetrical.

  • Also we know that the median of the data is the central tendency of the data and always best represents the data.

Hence, The median best represents the data set.

Please anyone!! I have an exam tomorrow! :(


Case 1: pH = 2.

1) find the molar concentration of H3O + or H+

pH = – log [H +] = 2 => [H+] = 10 ^-2 = 0.01 M

2) find the number of moles that will have 80 ml of a 0.01 M solution:

M = n /V => n = M * V = 0.01 M * 0.080 liter = 0.00080 moles

3) Find the volume of the 0.2 M solution that has 0.00080 moles of H+

 M = n / V => V = n / M = 0.00080 mol / 0.2 M = 0.004 liter = 4 ml.

That means that you can take 4 ml of the solution 0.2M HCl (which will contain 0.00080 moles of H+) and add water until complete 80 ml.  

You can verify: 0.00080 mol / 0.080 liter = 0.01 M

pH = log (1 / 0.01) = 2 .

Case 2: pH = 3.

1) concentration of H+

pH = – log [H+] = 3 => [H+] = 10^ -3 = 0.001

2) number of moles that will have 80 ml 0.001 M solution

M = n / V => n = M * V = 0.001M * 0.080 liter = 0.000080  moles

3) Volume of the 0.2 M solution that will contain 0.000080 moles

M = n / V => V = n / M = 0.000080 mol / 0.2 M = 0.0004 liter = 0.40 ml

Then, you can take 0.40 ml of 0.2 M HCl solution and add water until complete the 80 ml.
