When would you want to use the median over the mean for describing the measure of center for a data set?

zheka24 [161]

Hello!

Sometimes when there are outliers in a data set, for example 1, 20,25,26,30, one is the outlier and when you find the mean it will not represent the data in the most accurate way. This is when you use the median to represent the part of the data set that has the information that is close together.

I hope this helps!

Which expression is equivalent to 2x^2 – 2x + 7?

serious [3.7K]

2x^2 - 2x + 7 = 2(x^2 -x +3) + 1 = 2(x-0.5)^2 + 17/6

What is the amplitude of the function ?

koban [17]

Answer:

3

Step-by-step explanation:

First, find the midline by averaging the highest value (2) and the lowest value (-4). In other words, do (2+-4)/2. You get the midline as -1. Now find the distance from the midline to the top. Distance from -1 to 2 is 3. Amplitude is therefore 3.

Solve for m:3m\5+a=b

Shalnov [3]

Step-by-step explanation:

Assuming:

$\frac{3m}{5} + a = b$

subtract a from both sides

$\frac{3m}{5} = b - a$

multiply both sides by 5

$3m = 5(b - a)$

divide both sides by 3

$m = \frac{5(b - a)}{3}$

____________________

if,

$\frac{3m}{5 + a} = b$

multiply both sides by (5+a), then divide both sides by 3

$m = \frac{b(5 + a)}{3}$

Grayson is flying a kite, holding his hands a distance of 2.75 feet above the ground and letting all the kite’s string play out.

sergiy2304 [10]

The position of the kite with the point directly beneath the kite at the same

level with the hand and the hand for a right triangle.

The height of the kite above the is approximately <u>66.314 feet</u>.

Reasons:

The height of his hands above the ground, h = 2.75 feet

Angle of elevation of the string (above the horizontal), θ = 26°

Length of the string, <em>l</em> = 145 feet

Required:

The height of the kite above the ground.

Solution:

The height of the kite above the ground is given by trigonometric ratios as follows;

$\displaystyle Height \ of \ kite, \, k_h = \mathbf{h + l \times sin(\theta)}$

Therefore;

$\displaystyle Height \ of \ kite, \, k_h = 2.75 + 145 \times sin(26^{\circ}) \approx \mathbf{66.314}$

The height of the kite above the, $k_h$ ≈ <u>66.314 feet</u>
