Answer:
A boxplot offers us information that can be used to compare two variables. In particular, if one variable is quantitative and the other variable is qualitative, a boxplot is generated for each category of the qualitative variable. Therefore, through this graph it is possible to analyze the relationship between the amount of money spent on food and the gender of the person.
A circular diagram offers information for a single variable, especially of a qualitative type.
A histogram offers us information for a single variable, especially quantitative type.
A relational analysis between two variables could be done using options (D) or (E), however one of the variables of interest is of qualitative type and the other is of quantitative type, so the scatterplot and the two-way table.

Answer:
8√2 ≈ 11.31 meters
Step-by-step explanation:
The straight-line distance is the hypotenuse of an isosceles right triangle with legs 8 meters. So, the distance is 8√2 meters, about 11.31 meters.
_____
Of course, you know that a right triangle with legs 1 and 1 has a hypotenuse of ...
√(1² +1²) = √2 . . . . . given by the Pythagorean theorem
Scaling this by a factor of 8 meters gives you legs of 8 meters and a hypotenuse of 8√2 meters.
<h3>Answer: 5x-3</h3>
=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like
Then let's say we fill that box with the value 7. We would then have
If we put 3 in the box instead we'll have and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.
Yes, because 16 ounces = 1 lb.
3 x 11 = 33, which is 2 lbs 1 oz.
