The best predicted value of y for x = 9.9 is y = 83.42.
<h3>What is linear equation if two variables?</h3>
Linear equations with two variables are equations with one, zero, or infinitely numerous solutions where every of a two variables has the highest exponential order of 1.
Some key features regarding linear equation if two variables are-
- The two-variable linear equation has the conventional form ax + by + c = 0, where x and y are the variables.
- These solutions might also be expressed in pairs, such as (x, y).
- A graphical representation of a linear equation system in two variables involves two straight lines that can be intersecting, parallel, or coincident.
Now, according to the question;
The given equation is;
y = 55.8 + 2.79x
Calculate the value of y by substituting the value of x = 9.9.
y = 55.8 + 2.79×9.9
y = 83.42
Therefore, the best predicted value of y for x = 9.9 is 83.42.

The correct question is-
Eight pairs of data yield r = 0.708 and the regression equation y = 55.8 + 2.79x. Also, the mean y-value is 71.125. What is the best predicted value of y for x = 9.9?
Answer:
No, because the two shorter sides added must be longer than the longest side.
Also 1 squared plus 2 squared is not equal to 5 squared.

something
Step-by-step explanation:
Answer:
y = -8
Step-by-step explanation:
Use reverse operations to isolate the variable, y.
y = -8
Answer:
- Exact distance = feet
- Approximate distance = 127.2792 feet.
===========================================================
Explanation:
The area of the square is 8100 square feet, abbreviated ft^2.
Apply the square root to find the distance from any base to its adjacent counterpart (eg: from 1st to 2nd base). So we get sqrt(8100) = 90 ft as that side distance. Notice that 90*90 = 8100.
If you were to draw a line from 1st base to 3rd base, then you would split the square into two congruent right triangles. Each right triangle is isosceles (the two legs being 90 ft each).
Use the pythagorean theorem to find the hypotenuse.
The distance from 1st to 3rd base is roughly 127.2792 feet.
