What is the MAD of the data set? {10, 9, 16, 5, 10}

1 answer:

5 0

First, you'd find the mean of all the numbers by doing 10+9+16+5+10 = 50/5 = 10. Second, you'd subtract all values from the mean by doing
16 - 10 = 6
10 - 10 = 0
10 - 10 = 0
10 - 9 = 1
10 - 5 = 5
Lastly, finding the mean of all 5 numbers would be, 2.4! Hope this helps!! :D

Answer:

1/3 =0.33

Step-by-step explanation:

just substitute the values of x and y into the expression to get

4(2)+1 /3(3)^2

=8+1 /3×9

=9/27

=1/3

What are the solutions of the equation x^4 + 6x^2 + 5 = 0? Use u substitution to solve.

Radda [10]

Answer:

second option

Step-by-step explanation:

Given

$x^{4}$ + 6x² + 5 = 0

let u = x², then

u² + 6u + 5 = 0 ← in standard form

(u + 1)(u + 5) = 0 ← in factored form

Equate each factor to zero and solve for u

u + 1 = 0 ⇒ u = - 1

u + 5 = 0 ⇒ u = - 5

Change u back into terms of x, that is

x² = - 1 ( take the square root of both sides )

x = ± $\sqrt{-1}$ = ± i ( noting that $\sqrt{-1}$ = i ), and

x² = - 5 ( take the square root of both sides )

x = ± $\sqrt{-5}$ = ± $\sqrt{5(-1)}$ = ± $\sqrt{5}$ × $\sqrt{-1}$ = ± i $\sqrt{5}$

Solutions are x = ± i and x = ± i $\sqrt{5}$

Write the form of the partial fraction decomposition of the rational expression. Do not solve for the constants. 37 x2 − 6x

Dvinal [7]

Answer:

$\dfrac{A}{x}+\dfrac{B}{x-6}$

Step-by-step explanation:

Given the function $\dfrac{37}{x(x-6)}$ , to write the form of its partial fraction on decomposition, we will separate the two functions separated by an addition sign. The numerator of each function will be constants A and b and the denominator will be the individual factors of each function at the denominator. The partial fraction of the rational function is as shown below.

$= \dfrac{37}{x(x-6)}\\\\= \dfrac{A}{x}+\dfrac{B}{x-6}$

Since we are not to solve for the constants, hence the partial fraction is $\dfrac{A}{x}+\dfrac{B}{x-6}$

Multiple Choice: Choose the correct answer for questions 1 and 2.

pickupchik [31]

Answer:

The correct answer is:

C. Trisha is shorter than 75% of girls aged 16 to 18.

Step-by-step explanation:

When a dataset is divided into four equal parts, the first part is called the lower quartile. The data is usually sorted in ascending order before finding quartiles.

The lower quartile contains 25% of the whole data. The values in lower quartile are are less than 75% of the values.

If Trisha's height is in lower quartile that means her height is less than the girls in middle and higher quartile.

Hence,

The correct answer is:

C. Trisha is shorter than 75% of girls aged 16 to 18.
