An appropriate model is a quadratic, y=0.999x²-1.999x-3.

The r² value is 1, so it is a perfect fit.

Answer:

The required quadratic regression model is y=x^2-2x-3.

Step-by-step explanation:

The given data points are (-1,0), (1,-4), (2,-3), (4,5), (5,12). Plot these points on a coordinate plane.

From the graph it is clear that the given data forms a U-shaped curve. It means we have to find the quadratic regression model.

The general form of quadratic regression model is

y=ax^2+bx+c

Using technology we get,

a=1,b=-2,c=-3

The required quadratic regression model is

y=x^2-2x-3

Therefore the required quadratic regression model is y=x^2-2x-3.

Answer:

We can see that the denominators of both the numbers is not same

So in order to make it same for the both numbers, we will multiply the second number by 2/2 ,(which is basically 1 so it won't affect our calculations)

\frac{11}{2^2 * 5^2} - \frac{2}{2^2 * 5^2}

So we will just subtract the numbers now

\frac{9}{2^2 * 5^2} <em>This is the answer </em>

Find the sum of the first 12 terms of the sequence 512, 256, 128, … This is infinite series notation, the answer is NOT 896...
postnew [5]

Answer:

1023.75

Step-by-step explanation:

The sum of a geometric sequence is

sum = a( 1 - r^n) / (1-r)

where a is the first term  r is the common ratio and  r^n is the nth term

We need to find the common ratio

r = 256/512 = 1/2

sum = 512 ( 1 - 1/2^12) / ( 1-1/2)

       =512( 1-.000244141) / (.5)

       =512(.999755859) /.5

     =1023.75
