Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars. What is the mean absolute deviat

Daniel [21]

If number of cars recorded by Lynn is 1, 1, 2, 2, 2, and 4 cars then the mean absolute deviation of the number of cars is 0.7

<h3>What is the mean absolute deviation?</h3>

The mean absolute deviation of a data set is the average of the absolute deviations from a central point .

Data we have is

1,1,2,2,2,4

Mean can be calculated as

$&\text { Mean }=\frac{1+1+2+2+2+4}{6}\\ \\&\text { Mean }=\frac{12}{6} \\\\&\text { Mean }=2$

Absolute value between the data points and mean can be calculated as :

$\begin{aligned}&|1-2|=1 \\&|1-2|=1 \\&|2-2|=0 \\&|2-2|=0 \\&|2-2|=0 \\&|4-2|=2\end{aligned}$

Now mean absolute deviation can be calculated as :

$\begin{aligned}&\frac{1+1+0+0+0+2}{6} \\\\&=\frac{4}{6} \\\\&=0.66\end{aligned}$$$

Rounding to nearest ten

mean absolute deviation=0.7

If number of cars recorded by Lynn is 1, 1, 2, 2, 2, and 4 cars then the mean absolute deviation of the number of cars is 0.7

For which function is the domain -5 ≤ x ≤ -1 not appropriate? y = √3x y = 3x y = 3x y = x3

Maurinko [17]

There is no real values for the square root of a negative value, therefore that negative domain does not exist for the function y=√(3x).

What is the functions average rate of change over each interval?

telo118 [61]

we can use average rate of change formula

$\frac{f(b)-f(a)}{b-a}$

(a) x = -3 to x = -2

Firstly, we will find points

(-3, 0) and (-2,2)

now, we can plug these values into formula

and we get

$=\frac{2-0}{-2+3}$

$=2$

(b)x = -2 to x =1

Firstly, we will find points

(-2,2) and (1,-4)

now, we can plug these values into formula

and we get

$=\frac{-4-2}{1+2}$

$=-2$

(c) x = 0 to x =1

Firstly, we will find points

(0,-3) and (1,-4)

now, we can plug these values into formula

and we get

$=\frac{-4+3}{1-0}$

$=-1$

(d) x = 1 to x =2

Firstly, we will find points

(1,-4) and (2,0)

now, we can plug these values into formula

and we get

$=\frac{0+4}{2-1}$

$=4$

(e) x = -1 to x =0

Firstly, we will find points

(-1,0) and (0,-3)

now, we can plug these values into formula

and we get

$=\frac{-3-0}{0+1}$

$=-3$

(f) x = -1 to x =2

Firstly, we will find points

(-1,0) and (2,0)

now, we can plug these values into formula

and we get

$=\frac{0-0}{2+1}$

$=0$

Given the function ƒ(x) = x 2 - 4x - 5

Semmy [17]

Answer:

The zeroes of the function f(x) are -1 and 5.

Step-by-step explanation:

The given function is

$f(x)=x^2-4x-5$

The middle term can be written as -5x+x.

$f(x)=x^2-5x+x-5$

$f(x)=x(x-5)+(x-5)$

Taking out common factors.

$f(x)=(x-5)(x+1)$

Equate the given function equal to 0, to get the zeroes.

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

Using zero product property,

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

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

Therefore the zeroes of the function f(x) are -1 and 5.

The vertex of the function is at (2,-9) and the x-intercepts are at (-1,0) and (5,0). So the graph of given function is shown below.
