which statement about the mean absolute deviation (MAD) of a data set is not true

Answer:

k = -3

Step-by-step explanation:

Given

Solving

Answer:

Area = x4 + 4x3 + 3x2 - 4x - 4

Length = x3 +5x2 + 8x + 4

Width = Area / Length.

Performing long division with polynomial.

x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1

Width = x-1

Step-by-step explanation:

The value of the width of the rectangle is,

⇒ (x - 1)

We have to given that;

In a rectangle;

Area = x⁴ + 4x³ + 3x² - 4x - 4

Length = x³ +5x² + 8x + 4

We know that;

Width = Area / Length.

Hence, Performing long division with polynomial.

Width = x⁴ + 4x³ + 3x² - 4x - 4 / x³ +5x² + 8x + 4

         = x - 1

Thus, The value of the width of the rectangle is,

⇒ (x - 1)

Answer:

17hrs (a little more)

Step-by-step explanation:

The tank is 1500 gallon capacity, it already contains 200 gallons.

1500-200=1300

Now, you have to figure how many hrs it will take at 75 gallons / hr to reach the additional 1300 gallons.

1300÷75= 17.33

It says full, but not overflowing. So I would say around 17hrs

Answer:

Step-by-step explanation:

x²-2x-48 = (x²-2x +1) - 1 - 48

              = (x - 1)² - 49

Then

The vertex is (1 , - 49)

==================

x²-2x-48 = 0

⇔ (x - 1)² - 49 = 0

⇔ (x - 1)² = 49

⇔ x - 1 = 7 or x - 1 = -7

⇔ x = 8 or x = -6

Then

intercepts: x = 8,-6

[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]

let us first start with some basic information ~

A fraction can be represented as [tex]\frac{x}{y}\\[/tex] where ,

x is the numerator and y is the denominator !

the question asks us to do something that will help us get same denominator for both the terms !

so let's see what we should do in such a case ~

[tex] \frac{9}{10} \: and \: \frac{7}{8} \\ \\ \\ lets \: make \: the \: denominator \: of \: both \\ the \: terms \: reach \: 80 \: , \\ \\ \bold\orange{ \implies \: \frac{9}{10} \times \frac{8}{8} = }\bold\red{ \frac{72}{80}} \\ \\\bold\orange{ \implies \: \frac{7}{8} \times \frac{10}{10} =}\bold\red{ \frac{70}{80}} [/tex]

and we're done !

let's add some more info to be lil more clear ~

while converting the denominator of both the terms , we must multiply the same number ( this number refers to the one we'll have to multiply to the denominator to obtain the desired result ) with the denominator as well as with the numerator !

The true statements for the parabola in the image are:

Mathematically, the standard equation of the directrix lines for a parabola is given by y = a(x - h)² + 2.

Given the following data:

Vertex (h, k) = (4, 3).

Point (x, y) = (8, 6).

Next, we would determine the distance where point (8, 6) lies on the parabola:

y = a(x - h)² + 2

6 = a(8 - 4)² + 2

6 = a(4)² + 2

6 = 16a + 2

16a = 6 - 2

16a = 4

a = 4/16

a = 1/4.

Therefore, the equation becomes:

y = 1/4(x - 4)² + 2

When x = 2, we have:

y = 1/4(2 - 4)² + 2

y = 1/4(-2)² + 2

y = 1/4(4) + 2

y = 1 + 2

y = 3.

In conlusion, the true statements regarding the parabola in the image are:
