Answer:

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

= 5

θ =

arctan( ΔY )

ΔX

= 78.69006752598°

ΔX = 1 – -3 = 4

ΔY = 2 – -18 = 20

Distance (d) = √ΔX2 + ΔY2 = √416 = 20.396078054371

Equation of the line:

y = 5x – 3

When x=0, y = -3

When y=0, x = 0.6

Answer:

c. The sampling distribution of the sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed

Step-by-step explanation:

From the given data, we have;

The category of the sample = Retired individuals

The number of participants in the sample = 20

The duration of program = six-weeks

The improvement seen by most participants = Little to no improvement

The improvement seen by few participants = Drastic improvement

Therefore, given that the participants are randomly selected and the majority of the participants make the same observation of improvement in the time to walk a mile, we have that, the majority of the outcomes show little difference in walk times after the program, therefore, the distribution of the sample data is not skewed and can be assumed to be approximately normal

Multiply polynomials

Answer -2x^4 - 2x^3 + 22x^2 - 30x + 12

Here's your solution

=> (2x^2 - 4x + 2) - (x^2 + 3x - 6)

=> (2x^2 - 4x + 2) -x^2 - 3x + 6

=> firstly multiple whole with -x^2

=> -x^2(2x^2 - 4x + 2) = -2x^4 + 4x^3 - 2x^2

=> now with -3x

=> -3x(2x^2 - 4x + 2) = -6x^3 +12x^2 -6x

=> with 6

=> 6(2x^2 - 4x + 2) = 12x^2 - 24x + 12

=> now add all terms

=> -2x^4 - 2x^3 + 22x^2 - 30x + 12

hope it helps and your day will be full of happiness ^_^

Need help ASAP. Last two problems on my study guide, can't seem to solve them?

Dimas [21]

Answer:

9) 4

10) p¹⁵/q⁹

Step-by-step explanation:

As per the law of indices, (xᵃ)ᵇ=xᵃᵇ.

So divide 8 by 2 to get 4

10)

p(p⁻⁷q³)⁻²q⁻³

p(p¹⁴q⁻⁶)q⁻³ (because (xᵃ)ᵇ=xᵃᵇ)

pq⁻³(p¹⁴q⁻⁶)

p¹⁵q⁻⁹

p¹⁵/q⁹ (because x⁻ᵃ =1 /xᵃ)
