The upper-left coordinates on a rectangle are (-1, 4) left parenthesis, minus, 1, comma, 4, right parenthesis, and the upper-rig
Zanzabum

Answer:

Kindly refer to the attached images for the answer.

Step-by-step explanation:

Upper left coordinates of a rectangle are (-1, 4).

Upper right coordinates of the rectangle are (3, 4).

Perimeter of the rectangle = 24 units

Let A(-1, 4) and B(3, 4).

First of all, let us find the distance between the coordinates A and B.

Distance formula can be used to find the distance.

<em>Distance formula:</em>

<em></em>D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}<em></em>

Here, we have the following values:

x_1 = -1 \\y_1 = 4\\x_2 = 3\\y_2 = 4

AB = \sqrt{(3-(-1))^2+(4-4)^2} = 4\ units

Perimeter = 2 (Length + Width)\\\Rightarrow 24 = 2 \times (AB + BC)\\\Rightarrow 24 = 2 \times (4 + BC)\\\Rightarrow BC = 8

When we will move from point B to C, we will move downwards on y axis for a distance of 8 units therefore value of x coordinate will be same.

Therefore coordinates of C (3, 4-8) i.e. C (3, -4)

When we will move from C to D, the x coordinate will decrease for 4 units.

D (3-4, -4) i.e. D (-1, -4)

Kindly refer to the attached images for the answer.

What might you conclude if a random sample of 23 time intervals between eruptions has a mean longer than 108 ​minutes? Select al
Dahasolnce [82]

Answer:

What I would conclude when a random sample of 23 time intervals between eruptions has a larger mean longer than 108 minutes is that there must be an error that occurred somewhere while computing the result.

Step-by-step explanation:

Technically error can be explained as the estimated difference between the real value or calculated value and an observed value of a certain quantity.

basically we have three types of error which are;

1. systematic errors.

2.random errors.

3.Bluders.
