The upper-left coordinates on a rectangle are (-4,4), and the upper-right coordinates are (4,4).The rectangle has an area of 8 s

maw [93]

Answer:

Then the coordinate of point $C$ is $(4,3)$ , and the coordinate of point $D$ is $(-4,3)$ .

Step-by-step explanation:

Given that,

The upper-left coordinate on a rectangle is $(-4,4)$ .

The upper-right coordinate on a rectangle is $(4,4)$ .

Area of rectangle is $8$ square unit.

Let, $ABCD$ is a rectangle.

The coordinate of point $A$ is $(-4,4)$ and the coordinate of point $B$ is $(4,4)$ .

Diagram of rectangle $ABCD$ is shown below:

Now,

$AB=$ $\sqrt{(4+4)^{2}+(4-4)^{2} }$

$=\sqrt{(64+0)}$

$=\sqrt{64}$

$= 8\ unit$

∵Area of rectangle = Length $\times$ Breadth

$8$ square unit = $8\ unit$ $\times Breadth$

∴ Breadth $=1\ unit$

$BC=\sqrt{(4-4)^{2}+(y-4)^{2} }$

$=\sqrt{(y-4)^{2} }$

⇒ $1$ $=\sqrt{(y-4)^{2} }$

squaring both sides, we get

⇒ $1=(y-4)^{2}$

⇒ $(y-4)$ = ± $1$

∴ $y=3$

Then the coordinate of point $C$ is $(4,3)$ , and the coordinate of point $D$ is $(-4,3)$ .

In a certain school, students can choose whether to eat in the school’s cafeteria. A reporter working for the school’s newspaper

rosijanka [135]

Answer:

The statement that is true is B. Because students self-selected whether to eat in the cafeteria, the sampling method might be biased and the sample might not be representative of all students in the school.

Step-by-step explanation:

Because of students can decide if they eat in the cafeteria or not, the sample obtained by the reporter can be extrapolated only to the population of students that actually eat in the cafeteria, not to all students population. To make a conclusion of the degree of conformity of all students population, the poll should have been conducted in a hallway of the school (to get the opinion of all students, not only the ones that go to the cafeteria). In other way, the reporter are loosing the opinion of those students that are not happy with the new menu, and decide not going to the cafeteria.
