'The quadratic regression equation for the data set is y=ax2+bx+c where a≠0 .

Step-by-step explanation:

  • A quadratic regression is the process of finding the equation of the parabola that best fits a set of data.

Can someone help on these two thanks

Answer:

C & D

Step-by-step explanation:

For the first one, all you have to do is count how many numbers are behind the decimal point and add them together (1 + 3 = 4)  and then you count up the decimal 4 places which would be 0.7416.

For the second one, you divide the days by miles (18/3=6) then you divide the 6 by 72 which would be 12.

Hope this helps!

Draw and label a rectangular prism that has a surface area of 96 square meters.
Mashcka [7]
Basically what you need to do is draw 4 congruent rectangles and 2 comgriemt squares (The six sides of a rectangular prism). The sum of the area of these six quadrilaterals should equal 96. This would be my thought process.

Step 1: Sketch a Rectangular Prism

Step 2: Make some educated guesses on some possible side measurements for the quadrilaterals that form the prism.

Step 3: Guess and Check until the amount equals 96.

So we can guess that the sides of the rectangle might equal 2 and 3 units.

This would be 6 for the area. Times 4 for each of the 4 Rectangles. (24) and add the area of the ends of the prism (2*2*2) which is 8 and you will get 32.

Since we are looking for a surface area of 96 and not 32, we can assume that a 3*2*2 prism is not what we need. So we can try again with other values.

Let's try 6*3*3. 6*3*4 for the four rectangles plus 3*3*2 for the ends.

The vertex form of the equation of a parabola is y = 4(x - 2)2 - 1. What is the standard form of the equation?
Paladinen [302]
Ok so your original equation was y=4(x-2)²-1
Therefore we need to expand the bracket to find the original equation.
To do this we need to find (x-2)²=x²-4x+4
Now we multiply this by 4 and subtract 1
4x²-16x+15 Therefore B is the answer
