Good explanation, Alan. Here is an example for you, TitaniumRome.

If the numbers were 4,5,3,5,4,7,8,1,4, and 10,

then the mean would be (4+5+3+5+4+7+8+1+4+10)/2=25.5.

The median (not mean as Alan accidentally said) would be...

1,3,4,4,4,5,5,7,8,10

4.5 since when crossing out numbers on each side you get 4 and 5, which the average of is 4.5.

The mode is 4 because it appears 3 times, more frequent than any other number.

The range is 9 because the maximum (10) minus he minimum (1) is 9.

Hope this helped! 

The mean is the average obtained by adding all the values and dividing the result by the number of values.

The median is the middle value when they are sorted in order of size.

The mode is the most common value.

The range is the difference between the largest and the smallest.

.

Corrected 2nd line to say median not mean!! Thanks Anonymous4338.

Thank you! I got it from here :)

Use sin(22°) = 689/h  where h is the length of the gondola wire, to get h = 689/sin(22°) feet.

Then divide h by 130 feet per minute to get the ride time in minutes.

ride time = 689/(sin(22°)*130) minutes

$${\frac{{\mathtt{689}}}{\left(\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{22}}^\circ\right)}{\mathtt{\,\times\,}}{\mathtt{130}}\right)}} = {\mathtt{14.148\: \!175\: \!961\: \!532\: \!953\: \!6}}$$

ride time = 14 minutes to the nearest minute.

Multiply every term by 3 to get rid of the fraction.  You are then left with:

2x - 15 = 3x - 9

Can you take it from here?

We can rewrite the equation  as

y² - 150y + 35 = -x²

(y - 75)² - 5625 + 35 = -x²

(y - 75)² - 5590 = -x²

(y - 75)² = 5590 - x²

Now the right-hand side has a maximum value of 5590, because as x moves away from zero, in either the positive or negative direction, x² is positive and subtracts from 5590.  Therefore the maximum value of y is obtained when x is zero:

(y - 75)² = 5590

y = 75 + √5590 ≈ 150

So c. gives the maximum height.

1.  Set f(k) = 25

k² + 2k + 1 = 25 

k² + 2k - 24 = 0

(k - 4)(k + 6) = 0

So two limiting values in the domain are -4 and 6

2. Set f(k) = 64

k² + 2k + 1 = 64

k² + 2k - 63 = 0

(k - 7)(k + 9) = 0

So the other two limits are -9 and 7

The domain is  [-9, -4] ∪ [6, 7]

Wseameo is "awesome" scrambled

1/       take a chicken across the river, leave it there and return

2/       take a fox across the river, leave it there, take a chicken and return

3/       leave a chicken on the opposite side from a fox, and take the corn across the river and return

4/       finally, take a chicken under your arm and take it over the river.

If sin of theta is 3/5 then tan theta =?

                 sin(theta) = 3/5          ( opposite side over hypotenuse )

                 tan(theta) = 3/x          ( opposite side over adjacent side )

Answer:>  tan(theta) = 3/4

 $${\mathtt{x}} = {\sqrt{{{\mathtt{5}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{{\mathtt{3}}}^{{\mathtt{2}}}}}$$

 $${\mathtt{x}} = {\mathtt{4}}$$

My favorite songs:

• God save the Queen (I think the British Anthem is the most beautiful national Anthem in Europe)
• La Marseillaise (Yes, I love the French national Anthem, maybe because I'm French)
• La Marcha Real (No, I'm not spanish but I think that the Spanish Anthem is good... Even if it doesn't have lyrics)

I'm 26! years old. Why ?

Good job, DB!

[3+(3/7)] times 7 is 24.

2*2*2*2*2*2*2=128.

Unscrambled it is "awesome".

easy,the answer is 49

16 XD

Is the answer 8+6+9= 23?

I hope this cookie is small enough

And congratulations Melody

Precisely.

$${\mathtt{\,-\,}}\left({{\mathtt{1}}}^{{\mathtt{2}}}\right) = -{\mathtt{1}}$$ but

$${\left(-{\mathtt{1}}\right)}^{{\mathtt{2}}} = {\mathtt{1}}$$

So $${\frac{\left({\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{5}}\right)}{\left({\mathtt{\,-\,}}{{\mathtt{1}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}}\right)}} = {\frac{{\mathtt{20}}}{\left({\mathtt{\,-\,}}{\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}}\right)}} = {\frac{{\mathtt{20}}}{{\mathtt{4}}}} = {\mathtt{5}}$$
