Answer:

Now I am not completely sure but...maybe is it that:

A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:

y = a x 2 + b x + c where a ≠ 0 .

Cause I think it might be the best way to find this equation manually is by using the least squares method. That is, we need to find the values of a , b ,     and     c such that the squared vertical distance between each point ( x i , y i ) and the quadratic curve y = a x 2 + b x + c is minimal.

The matrix equation for the quadratic curve is given by:

[ ∑ x i 4 ∑ x i 3 ∑ x i 2 ∑ x i 3 ∑ x i 2 ∑ x i ∑ x i 2 ∑ x i n ] [ a b c ] = [ ∑ x i 2 y i ∑ x i y i ∑ y i ]

Which expression has a conflict of 10 and a constant of5
Natalka [10]

The expression that has a coefficient of 10 and constant of 5 is 10x + 5.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

A coefficient is a number or any symbol representing a constant value that is multiplied by a variable. A constant is a value or number that never changes in expression.

The expression that has a coefficient of 10 and constant of 5 is 10x + 5.

Answer:

See below

Step-by-step explanation:

<u>Mercury-2.3 cm </u>   The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Venus - 4.3 cm</u>      The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Earth-6 cm</u>            There is no hundreths value so the tenths stays the same.

<u>Mars-9.1 cm</u>           The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Jupiter- 31.1 cm</u>      The hundreths value isn't greater than 5, so the tenths stays the same.

<u>Saturn- 57.4 cm</u>     The hundreths value <u><em>is</em></u> greater than 5, so the tenths values is raised by 1.

<u>Uranus-114.9 cm </u>   The hundreths value isn't greater than 5, so the tenths stays the same.

Neptune-179.8 cm  There is no hundreths value so the tenths stays the same.
