The coordinates of the top of a tree are (-3,8), and an acorn is attached to the tree at (-1,5). If we know that the acorn lies
Charra [1.4K]

Let's say that the coordinates of the squirrel are: (x, y)

Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.

To work out the midpoint you do:

(sum of x-coordinates) divided by 2,  (sum of y coordinates) divided by 2.

We can use this to form an equation .

So the sum of the x coordinates of the tree and the squirrel = -1   :

x-coordinates of the squirrel:

\frac{-3+x}{2}=-1                   <em>(now solve for x)</em>

-3+x = -2

x=1

y-coordinates:

\frac{8+y}{2}=5                   <em>(now solve for y)</em>

8+y=10

y = 2

So the coordinates of the squirrel are: (1, 2)

What is the value of x to the nearest tenth?<br> Need help..
satela [25.4K]
Using the tangent rule:
 Tangent(angle) = Opposite leg /  Adjacent leg

We will use the 23 degree angle to solve for x.

Tangent(23) = X / 6

x = 6 * tangent(23)

x = 2.5

Oksi-84 [34.3K]

Answer:

a. 0.017

b. 0.013

c. 0.021

Step-by-step explanation:

Let p be the probability that a randomly selected man is 65 or older

And q be the probability that a randomly selected woman is 65 or older

Then p=0.114 and q=0.146

Using the multiplication rule for independent events:

a. If a man is selected at random and a woman is selected at random, the probability that both people selected are 65 or older is p × q = 0.114 × 0.146 ≈ 0.017

b. If two men are selected at random, the probability that both of them are 65 or older is p × p = 0.114 × 0.114 ≈ 0.013

c. If two women are selected at random, the probability that neither of them is 65 or older is q × q = 0.146 × 0.146 ≈ 0.021

Is 1.3 greater than negative 5
Gemiola [76]
1.3 would be considered greater than negative 5. Although 1.3 is a decimal it is still a positive number and positives are worth more than negatives regardless
