Answer:

It's a trick, the MAD is secretly the Mean, just copy your answer, i found this - To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

Jessica bought 3/4 lb of berries. Mary bought 1/6 lb of berries less the jessica. what is the total weight of berries in pounds

Mrrafil [7]

Given that number of pounds of berries that Jessica bought = $\frac{3}{4}$ lb

Given that "Mary bought $\frac{1}{6}$ lb of berries less the jessica"

then number of pounds of berries that Mary bought

$=(\frac{3}{4}-\frac{1}{6})$ lb

$=\frac{3}{4}\cdot\frac{3}{3}-\frac{1}{6}\cdot\frac{2}{2}$ lb

$=\frac{9}{12}-\frac{2}{12}$ lb

$=\frac{7}{12}$ lb

Now we need to find the total weight of berries in pounds that they bought.

To find that we just need to add both values.

$\frac{3}{4}+\frac{7}{12}$

$=\frac{3}{4}\cdot\frac{3}{3}+\frac{7}{12}$

$=\frac{9}{12}+\frac{7}{12}$

$=\frac{16}{12}$

$=\frac{4}{3}$

Hence final answer is $\frac{4}{3}$ lb.

45.22x1.20= 54.26
Divide that total by 2 because you as splitting it
54.26/2= 27.13
You both pay $27.13

Is y greater than negative infinity or less than in this graph?

Blababa [14]

The arrows indicates the line will go on forever. This is called a ray, a line that will go on infinitely.

The line is neither greater than or equal to.

The line is infinite.

The graph highlights two other points on the trend line. Use them to find another equation for the trend line shown for this sca

Natasha2012 [34]

The general equation of the line:
y = mx + c
where m is the slope of the line , and c is constant
m will be calculated using the points (2,1162) , (11,1900) as follow

m = (1900-1162)/(11-2) = 82

∴ y = 82 x + c

By substituting with the point (2,1162) to find c
∴ c = y - 82x = 1162 - 82 * 2 = 998

∴ y = 82x + 998

The first choice is the correct answer

Which of the following are true statements?

Alika [10]

Answer:

I and II.

Step-by-step explanation:

Dot plots are charts that represent data points on a simple scale using filled circles. Stemplots allow plotting data by dividing it into stems (largest digit) and leaves (smallest digits). Both dot plots and stemplots are like histograms since they allow to compare data relating to only one variable, and are used for continuous, quantitive data, highlighting gaps, clusters, and outliers.

Histograms use bars to represents amounts, with no space between the bars and the height of the bars is proportional to the frequency or relative frequency of the represented amount. We refer to the relative frequency of a case when this frequency is divided by the sum of all frequencies of the cases. The proportionality between the height of the bar and the frequency is right when the width (interval) of the bar is the same for everyone, on the contrary, the area of the bar would be proportional to the frequency of cases.

Therefore, of all the above, the correct statements are I and II. Statement III is incorrect because relative heights are proportional to relative frequencies.

I hope it helps you!
