Hello! To solve this problem, we can write out and solve a proportion. Set it up like this: 6/3 = x/15. We’re looking for the height of the pine tree, but we know the length of the shadows, so they line up with one another and “x” goes at the top. Let’s cross multiply the values to get 90 = 3x. Now, divide each side by 3 to isolate the “x”. 90/3 is 3. x = 30. The pine tree is 30 feet tall.

(52+2)-3x -6<br><br> help me with thanks
Yuri [45]

Answer:

48 - 3X

Step-by-step explanation:

( 52+2) - 3x - 6

54 - 3x - 6    So first we deal with the numbers in brackets and that is 52 + 2 giving us 54.

54 - 6 - 3x  Then you simplify the expression that is collecting like terms so then we subtract 6 from 54

48 - 3x This is the final expression after simplifying

Two events A and B are independent with Upper P left-parenthesis Upper A right-parenthesis equals Upper P left-parenthesis Upper
soldi70 [24.7K]

Answer:

The value of P (A ∩ B) is 0.25.

Step-by-step explanation:

Independent events are those events that do not effect the occurrence of each other, i.e. if event <em>X </em>and <em>Y</em> are independent then the occurrence of <em>X</em> and <em>Y </em>are not influenced by each other.

For independent events <em>X</em> and <em>Y</em> the joint probability of <em>X</em> and <em>Y</em> is:

P (X\cap Y)=P(X)\times P(Y)

It is provided that events <em>A</em> and <em>B </em>are independent of each other.

And P (A) = P (B) = 0.50.

Compute the value of P (A ∩ B) as follows:

P (A\cap B)=P(A)\times P(B) \\= 0.50\times0.50\\=0.25

Thus, the value of P (A ∩ B) is 0.25.

Suppose you toss a coin 100 times and get 60 heads and 40 tails. Based on these results what is the probability that the next fl
Nata [24]
The probability is 1/2. Even if you flip heads 100 times in a row, you still have a 50/50 chance of flipping heads or tails. The probability does not change no matter how many times you flip a certain side.

SOLVE USING ELIMINATION *20 POINTS*
V125BC [204]

1. No answer ( may be due to incorrect question)

2. x = -3

y = 4

3. x= 4

y = 2

4.x = -63/40

y= -19/20

Step 1

Multiply equation 1 by the coefficient of x in equation 2

Multiply equation 2 by the coefficient of x I'm equation 1

(after completing this step you will derive equation 3 and 4 )

Step 2

Subtract equation 4 from equation 3

Step 3

Divide both sides of the equation by the coefficient of y

Step 4

substitute your value for y in equation 1 or 2

(after this you will derive the values of x)

Note : This method is for the Elimination of x

I hope it helps
