What is the means-to-MAD ratio of the two data sets, expressed as a decimal to the nearest tenth?

1 answer:

4 0

Frist we need to find the mean of both so

1.55

2.67

then we make a number graph and see how mant place does it take to get to them from 0 67and55/by them selfs = 1.2(rounded)

1.2 is you answer

Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)

Mkey [24]

<h2><u>Polynomial Function</u></h2>

<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>

To determine the answer, substitute the given value to the function and simplify.

h(x) = 3x² + 2 - 2x; h(-2)
h(-2) = 3(-2)² + 2 - 2(-2)
h(-2) = 3(4) + 2 + 4
h(-2) = 12 + 2 + 4
h(-2) = 14 + 4
h(-2) = 18

<u>Answer:</u>

<u>18</u> is the answer.

(5x4 - 4x³ - 2x² + x − 19) − (x4 + 5x³ + 8x² + x + 5) evaluate !!

MAXImum [283]

Answer:

$p(x) = 4x^4-9x^3-10x^2-24$

Step-by-step explanation:

I'm going to assume that your equation is $(5x^4-4x^3-2x^2+x-19) - (x^4+5x^3+8x^2+x+5)$
So to evaluate it we need to simplify it. Find like terms and perform addition/subtraction on them.

$p(x) = (5-1)x^4 + (-4-5)x^3+(-2-8)x^2+(1-1)x+(-19-5) \\ \to p(x) = 4x^4-9x^3-10x^2-24$

A the slope of the line is 1

to calculate the slope m , use the ' gradient formula '

m = ( y₂ - y₁ ) /( x₂ - x₁ )

where (x₁, y₁ ) = 6, 3) and (x₂, y₂ ) = (9, 6)

m = $\frac{6 - 3}{9 - 6}$ = $\frac{3}{3}$ = 1

Kudos to the poster on the typeset math.

With cube roots we don't have to worry that things are positive.

$\sqrt[3]{16 x^4} - \sqrt[3]{128 x} = \sqrt[3]{2^4 x^4} - \sqrt[3]{2^7 x} = \sqrt[3]{2^3 x^3 2x} - \sqrt[3]{4^3 2 x} = 2x\sqrt[3]{2x} - 4\sqrt[3]{2 x}$

$= (2x-4)\sqrt[3]{2 x}$
