Part A: A highway's path can be found using the equation 2x - 3y = 21. Use the graphs of the functions to determine the number o
EastWind [94]

Answer:

Step-by-step explanation:

Part A

2x-3y =21 in slope-intercept form is y=2/3x-7 one you graph the equation it would be a parallel to the equation shown above so there are no intersections

PART B

y=1/3x^2 and y= 2/3x - 5

1/3x^2 = 2/3x-5

1/3x^2=2/3x-5

then u multiply everything by 3

1/3x^2*3 =2/3x *3-5*3

the three for 1/3*3 cancels out so you are left with

1x^2= 2x -15

1x^2-2x+15=0

You can not factor it and well i guess there is no intersection

im sorry if i got this wrong bc i had a similar question just different numbers and i tried to solve this one the way i sloved mine so im not sure of my answer for part b

3. Using techniques from Calculus, show directly that the maximum value of a 1-D Gaussian distribution occurs at the point x = μ
Vilka [71]

Answer:

For a scaler variable, the Gaussian distribution has a probability density function of

p(x |µ, σ² ) = N(x; µ, σ² ) = 1 / 2π×e^{\frac{-(x-u)^{2}}{2s^{2} }  }

The term will have a maximum value at the top of the slope of the 1-D Gaussian distribution curve that is when exp(0) =1 or when x = µ

Step-by-step explanation:

Gaussian distributions have similar shape, with the mean controlling the location and the variance controls the dispersion  

From the graph of the probability distribution function it is seen that the the peak is the point at which the slope = 0, where µ = 0 and σ² = 1 then solution for the peak = exponential function = 0 or x = µ
