A=# of packs of chewing gum (7)    b=# of bottles of water 

0.75a + 1.25b _<_ 22      (substitute for a and b) 
0.75(7) +1.25b _<_ 22 


the sign is < because the total amount of the money she spends has to be less or equal to $22

The answer is D.

Which statements best describe the dot plot or box plot? Check all that apply
Sveta_85 [38]

Answer:

<h2>The box plot is the only display that can be used to show the variability of the data.</h2><h2>The median appears clearly on the box plot at the line within the box: 10.</h2>

Step-by-step explanation:

When we want to represent variability, we use a box plot instead of a dot plot, because the box plot allow us to observe the range of the data set, that is, the minium and the maximum value.

Remember that variability is about the spread of the dataset, and the range is a measure that can give a pretty good idea of it, shown by a box plot.

Therefore, the last hoice is correct.

On the other hand, according to the dot plot, the median is 10, because there are 13 total values, where the central value is 10.

Therefore, the second choice is correct.

Explain why the polynomial 100x^2 + 150x + 49 is not a perfect square.
Ad libitum [116K]
Answer: The correct answer is Choice C.

For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2

This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.
