Please find the value of x in the figure

Mathematics
1 answer:

Answer:

Step-by-step explanation:

E is the midpoint of Ac & D is the midpoint of AB

DE = (1/2)BC        {Midpoint theorem}

x +1 = \dfrac{1}{2}(4x - 6)\\\\\\
Multiply \ the \ whole \ equation \  by 2\\\\
2*(x+1) =2*\dfrac{1}{2}*(4x - 6)

2*x + 2*1 = 4x - 6

2x + 2 = 4x - 6

Add 6 to both sides

2x + 2 + 6 = 4x

2x + 8 = 4x

Subtract 2x from both sides

8 = 4x - 2x

2x = 8

Divide both sides by 2

x = 8/2

x = 4

How to find the percent of change between numbers


First: work out the difference (increase) between the two numbers you are comparing.


Increase = New Number - Original Number


Then:  divide the increase by the original number and multiply the answer by 100.


% increase = Increase ÷ Original Number × 100.


If your answer is a negative number, then this is a percentage decrease.


To calculate percentage decrease:

First: work out the difference (decrease) between the two numbers you are comparing.


Decrease = Original Number - New Number


Then: divide the decrease by the original number and multiply the answer by 100.\


% Decrease = Decrease ÷ Original Number × 100


If your answer is a negative number then this is a percentage increase.


If you wish to calculate the percentage increase or decrease of several numbers then we recommend using the first formula. Positive values indicate a percentage increase whereas negative values indicate percentage decrease.

The answer is 24.22%

A football coach is trying to decide: When a team is ahead late in the game, which strategy is better?
PSYCHO15rus [73]

Answer:

You are more likely to win by playing regular defense.

Step-by-step explanation:

Assume out of 100 reviewed games, there were 50 regular defense games and 50 prevent defense games. And out of 50 regular defense games, 38 were win, 12 were lose. And out of 50 prevent defense game, 29 were win, 21 were lose.

Probability to win the game by playing regular defense is:

P(win | regular) = 38/50 = 0.76

Probability to win the game by playing prevent defense is:

P(win | prevent) = 29/50 = 0.58

Since the probability of winning by regular defense game is more than prevent defense game (0.76 > 0.58), you are more likely to win by playing regular defense.
