a) 3 goals

The median is the middle number of a data set. The best way to find the median is to list out all of the goals (and their frequencies!) and cross off numbers from the outside in until we find the median, or middle number.

0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4

1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4

1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4

1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3

1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3

2, 2, 2, 2, 3, 3, 3, 3, 3, 3

2, 2, 3, 3, 3, 3

3, 3

The median is 3 goals.

b) 2.33 goals

To find the mean, we add up all of our listed numbers below and divide by the total number of terms we added together.

0(2) + 1(8) + 2(4) + 3(10) + 4(6) = 70

total number of terms = 2 + 8 + 4 + 10 + 6 = 30

70 / 30 = 2.33

The mean number of goals conceded was approximately 2.33.

Hope this helps! :)

Answer the question in the picture

Svet_ta [14]

<h3>Answer:</h3>

left picture (bottom expression): -cot(x)
right picture (top expression): tan(x)

<h3>Step-by-step explanation:</h3>

A graphing calculator can show you a graph of each expression, which you can compare to the offered choices.

_____

You can make use of the relations ...

... sin(a)+sin(b) = 2sin((a+b)/2)cos((a-b)/2)

... cos(a)+cos(b) = 2cos((a+b)/2)cos((a-b)/2)

... cos(a)-cos(b) = -2sin((a+b)/2)sin((a-b)/2)

Then you have ...

$\dfrac{\cos{2x}-\cos{4x}}{\sin{2x}+\sin{4x}}=\dfrac{2\sin{3x}\sin{x}}{2\sin{3x}\cos{x}}=\dfrac{\sin{x}}{\cos{x}}=\tan{x}$

and ...

$\dfrac{\cos{2x}+\cos{4x}}{\sin{2x}-\sin{4x}}=\dfrac{2\cos{3x}\cos{x}}{-2\cos{3x}\sin{x}}=\dfrac{-\cos{x}}{\sin{x}}=-\cot{x}$
