He dot plots show the number of hours a group of fifth graders and seventh graders spent playing outdoors over a one-week period

garik1379 [7]

Answer:

The left side of the data looks similar to the right side in the seventh-grade data, but not in the fifth-grade data.

Step-by-step explanation:

In the seventh-grade data, we can split dots into two equal groups, one from 0 to 3 and the other one from 4 to 7. In the first group the dot distribution is {2, 2, 3, 5}. In the second group the dot distribution is {5, 3, 3, 1}. Then, the left side looks similar to the right side (they are symmetrical).

If we perform a similar division between dots for fifth-graders data, we obtain one group, from 1 to 4, which dot distribution is {2, 3, 1, 4}; and another group, from 5 to 8, which dot distribution is {5, 5, 2, 2}. Then, the left side doesn't look similar to the right side (they aren't symmetrical).

What is the area of the triangle in the diagram?

Schach [20]

Answer:

$\frac{(a-b)^2+b^2}{a^2}$

which agrees with the first choice (A) in your list of possible answers

Step-by-step explanation:

Notice that the area of the outer square is given by the square of it side $(a)$ .Then the outer area is given by: $a^2$

Now, the inner square's area we calculate by subtracting from the outer area four equal right angle triangles (those shaded in grey in the figure provided). Each of such right angle triangles have an area given by the general formula of a triangle's area:

$Area_{triangle}= \frac{base\,*\,height}{2} =\frac{(a-b)\,b}{2} =\frac{ab-b^2}{2}$

Therefore the internal square's area is:

$a^2-4\frac{ab-b^2}{2} =a^2-2ab+2b^2$

And then the quotient of this are over the larger square area becomes:

$\frac{a^2-2ab+2b^2}{a^2} =\frac{a^2-2ab+b^2+b^2}{a^2}=\frac{(a-b)^2+b^2}{a^2}$
