Answer:
Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.
Step-by-step explanation:
Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is 
.
Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into 
each.
By alternate angle property,
Tan = 
= Tan × 10
= 7.00021
⇒ x = 2 × 7.0021
= 14. 0042
x = 14
Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.
The mean will always equal 0.
The variable for the mean is μ
Answer:
2
Step-by-step explanation:
if you get a pizza and cut it to 9 pieces you get 2 slices the fraction is 9/2
The dice can roll a 1, 2, or 3 out of 6 options to be less than 4. That's 3/6 or 1/2.
First we compute the distance between the center and the given point which is exactly the radius
r =
Now that we know the center and the radius, we can write the equation of a circle with given radius and center:
where (h,k) represent the coordinates of the center (3,7).
We substitute and obtain
