Daniel looks at the prices of 5 guitars. The prices are $137, $159, $127, $188 and $680. These prices contain one extreme value

Answer:

D. Mean absolute deviation

Step-by-step explanation:

Median gives us : 159

Range gives us: 680 - 127 = 553

mean gives us :

127+137+159+188+680 = 1291

1291 / 5

= 258.2

MAD gives us the mean deviation (avg change from the mean):

mean

= 258.2

258.2 - 127 =131.2

258.2 - 137 =121.2

258.2 - 159 =99.2

258.2 - 188 =70.2

680 - 258.2

=421.8

Find the mean of the variances:

70.2+99.2+121.2+131.2+421.8 = 843.6

843.6 / 5

= 168.72

Mad = 258.2 +- 168.72

Complete the steps to solve the polynomial equation x3 – 21x = –20. According to the rational root theorem, which number is a po

Answer:

Zeroes : 1, 4 and -5.

Potential roots: $\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20$ .

Step-by-step explanation:

The given equation is

$x^3-21x=-20$

It can be written as

$x^3+0x^2-21x+20=0$

Splitting the middle terms, we get

$x^3-x^2+x^2-x-20x+20=0$

$x^2(x-1)+x(x-1)-20(x-1)=0$

$(x-1)(x^2+x-20)=0$

Splitting the middle terms, we get

$(x-1)(x^2+5x-4x-20)=0$

$(x-1)(x(x+5)-4(x+5))=0$

$(x-1)(x+5)(x-4)=0$

Using zero product property, we get

$x-1=0\Rightarrow x=1$

$x-4=0\Rightarrow x=4$

$x+5=0\Rightarrow x=-5$

Therefore, the zeroes of the equation are 1, 4 and -5.

According to rational root theorem, the potential root of the polynomial are

$x=\dfrac{\text{Factor of constant}}{\text{Factor of leading coefficient}}$

Constant = 20

Factors of constant ±1, ±2, ±4, ±5, ±10, ±20.

Leading coefficient= 1

Factors of leading coefficient ±1.

Therefore, the potential root of the polynomial are $\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20$ .
