g During winter, red foxes hunt small rodents by jumping into thick snow cover, without any visual clue. Researchers examined th

Setler79 [48]

Answer: False

Step-by-step explanation:

Events can be classed as being dependent or independent depending on whether the outcome of a certain event affects the outcome of another. In the scenario above, the success rate of jumps in the Northeast direction is higher than in the southwest direction and even much than in other directions. With these uneven rate of success, the probability that a fox will have a successful jump will depend on the direction in which the fox is jumping. With an high expected success probability in the Northeast and southwest than in other directions

The diameter of a circle is 12 feet. what is the area?give the exact answer in simplest form.

Xelga [282]

The area of a circle (A) with radius "r" is:

$A=\pi\cdot r^2$

To solve this question, follow the steps below.

Step 01: Find r.

The radius is half the measure of the diameter.

$r=\frac{D}{2}$

Given D = 12 feet, then:

$\begin{gathered} r=\frac{12}{2} \\ r=6 \end{gathered}$

Step 02: Find A.

Use r = 6 feet to find A.

$\begin{gathered} A=\pi\cdot6^2 \\ A=36\pi \end{gathered}$

Answer: The area is 36π square feet.

The midpoint of line AB is (14,26). One endpoint of line AB is A(32, 40). What are the coordinates of B?

bogdanovich [222]

The coordinates of the midpoint:
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
(x₁,y₁) - the coordinates of one endpoint
(x₂,y₂) - the coordinates of the other endpoint

The midpoint is (14,26).
One endpoint is A(32,40).
The other endpoint is B.

The x-coordinate of B:
$\frac{32+x}{2}=14 \ \ \ |\times 2 \\
32+x=28 \ \ \ |-32 \\
x=-4$

The y-coordinate of B:
$\frac{40+y}{2}=26 \ \ \ |\times 2 \\
40+y=52 \ \ \ |-40 \\
y=12$

The coordinates of B are (-4,12) - the answer is C.
