Answer

standard deviation

Explanation

Standard deviation is the measure of spread of data around the mean.

Mode is the most common value - which would be the mean in a normal-like distribution.

Median is the middle value when the data is ranked in ascending order (or descending even)

Skewness, is when the mode of the data falls behind the mean by a large margin.

An example is GDP, a few billionaires increase the number number and distort it, even though most people are of low or middle based income.

Answer:

7.2 units

Step-by-step explanation:

Coordinates of city A = (0, 0)

Coordinates of city B = (6, 4)

Use the distance formula to find the distance between the two cities as follows:

$AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$A(0, 0) = (x_1, y_1)$

$B(6, 4) = (x_2, y_2)$

Plug in the values into the formula

$AB = \sqrt{(6 - 0)^2 + (4 - 0)^2}$

$AB = \sqrt{(6)^2 + (4)^2}$

$AB = \sqrt{36 + 16} = \sqrt{52}$

$AB = 7.2$ (nearest tenth)

Suppose that is an angleand y is not in the first quadrant. Compute the exact value of secyYou do not have to rationalize the de

Pavel [41]

ANSWER :

The answer is :

$-\frac{5\sqrt{10}}{9}$

EXPLANATION :

Note that cotangent is only positive when the angle is in the first or third quadrant.

Since y is not in the first quadrant, it must be in the third quadrant.

So the x and y are both negative.

An angle with a terminal point (x, y)

The cotangent is x/y

We can equate :

$\cot\gamma=\frac{9}{13}=\frac{x}{y}$

Since x and y are both negatives, x = -9 and y = -13

We can have the triangle :

The hypotenuse will be :

$\begin{gathered} c=\sqrt{(-9)^2+(-13)^2} \\ c=5\sqrt{10} \end{gathered}$

We are asked to find the value of sec y.

In an angle with a terminal point (x, y)

The secant is :

$\sec\gamma=\frac{\text{ hypotenuse}}{x}$

The hypotenuse is 5√10 and x = -9

The value of sec will be :

$\begin{gathered} \sec\gamma=\frac{5\sqrt{10}}{-9} \\ \\ =-\frac{5\sqrt{10}}{9} \end{gathered}$

Solve the equation or inequality 3/2t-16=4/3t-6

Tamiku [17]

Answer:

<em>t=60</em>

Step-by-step explanation:

3/2t-16=4/3t-6

(subtract 4/3t from both sides)

3/2t-16-4/3t=-6

(add 16 to both sides)

3/2t-4/3t=-6+16

(simplify)

1/6t=10

(divide by 1/6 (or multiply by 6 on both sides)

t=60
