OK, I'll give tips on absolute value.

No matter what type of number it is it always equals to a positive number.

ex: |-3| = 3, |15| = 15

Hope this help :( P.S. Sorry if its sloppy.

Here's an example: If you have -9 and it asks for the absolute value of it, it means the opposite. The absolute value of -9 is positive 9.

The average number of minutes Americans commute to work is 27.7 minutes. The average commute time in minutes for 48 cities are a

dolphi86 [110]

Answer:

a) $\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = 27.2$

b) For this case we have n =48 observations and we can calculate the median with the average between the 24th and 25th values on the dataset ordered.

20.4 20.4 20.5 21.7 22.3 23.3 23.6 23.7 23.7 23.7 23.9 23.9 24.1 24.3 24.7 24.9 25.1 25.1 25.1 25.2 25.3 25.6 26.1 26.1 26.4 26.5 26.7 27.1 27.1 27.4 27.6 28.4 28.6 28.6 28.7 28.8 28.8 29.6 31.0 32.0 32.0 32.4 32.5 32.9 33.1 34.5 38.4 44.1

For this case the median would be:

$Median = \frac{26.1+26.4}{2}=26.25 \approx 26.3$

c) $Mode= 23.2, 25.1$

And both with a frequency of 3 so then we have a bimodal distribution for this case

Step-by-step explanation:

For this case we have the following dataset:

23.6, 26.5, 28.6, 28.6, 23.7, 25.3, 24.9, 28.7, 26.7, 32.4, 20.4, 23.9, 32.0, 32.5, 23.7, 26.1, 21.7, 26.1, 38.4, 24.1, 20.5, 25.2, 31, 26.4, 27.1 ,25.1, 25.1, 23.7, 23.9, 32.9, 28.8, 25.6, 28.8, 28.4, 32, 27.6, 29.6, 44.1, 27.1, 24.7, 22.3, 24.3, 23.3, 27.4, 20.4, 25.1, 34.5, 33.1

Part a

We can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = 27.2$

Part b

For this case we have n =48 observations and we can calculate the median with the average between the 24th and 25th values on the dataset ordered.

For this case the median would be:

$Median = \frac{26.1+26.4}{2}=26.25 \approx 26.3$

Part c

For this case the mode would be:

$Mode= 23.2, 25.1$

And both with a frequency of 3 so then we have a bimodal distribution for this case

Mrs. Sampson is using this recipe to make cookies.

Volgvan

Answer:

Option C) Mrs. Sampson needs to use 1/4 cup of milk

Step-by-step explanation:

we know that

If Mrs. Sampson has only 4 tablespoons of butter, then the amounts of the ingredients to be used will be half (50%) of the recipe

sugar ----> 2/2=1 cup of sugar

butter ---> 8/2=4 tablespoons of butter

milk ---> (1/2)/2=1/4 cup of milk

baking cocoa ---> (1/3)/2=1/6 cup of baking cocoa

oats ----> 3/2=1.5 cups of oats

therefore

Mrs. Sampson needs to use 1/4 cup of milk.
