Hello there!
Let me try :)
You decided to tell someone to make a book for you. You need to tell him what shape you would like the book to have. But since you want it to be quadrilateral, you need to go there and make sure that the person is doing it correctly. So that they don't give you the book with a shape of a triangle, then you would have problem to add it on your shelf because it wouldn't look interesting.
Note: A quadrilateral is defined as a polygon (a closed shape) with 4 sides,
so any shape/object with four sides can be considered a quadrilateral.
I hope this helps!
Answer:
f(x) = -4/3x² -2/3x +10
Step-by-step explanation:
The quadratic regression function of a graphing calculator or spreadsheet can determine the equation for you.
___
Or, you can determine it yourself.
The equation can be written in the form ...
f(x) = a(x +3)(x -5/2) . . . . . . . using the given x-intercepts
for some value of "a"
For x = 0, this must match the y-intercept.
f(0) = a(0 +3)(0 -5/2) = 10
-15/2·a = 10
a = -20/15 = -4/3
So, the function can be written as ...
f(x) = (-4/3)(x +3)(x -5/2)
or
f(x) = -4/3x² -2/3x +10
Slope is the change in Y over the change in X. It is calculated by finding the difference between the y values, and the difference in x values.

Answer: (2.54,6.86)
Step-by-step explanation:
Given : A random sample of 10 parking meters in a beach community showed the following incomes for a day.
We assume the incomes are normally distributed.
Mean income : 
Standard deviation : 


The confidence interval for the population mean (for sample size <30) is given by :-

Given significance level : 
Critical value : 
We assume that the population is normally distributed.
Now, the 95% confidence interval for the true mean will be :-

Hence, 95% confidence interval for the true mean= (2.54,6.86)
