1 answer:
Given:
The table of values.
To find:
The least-squares regression line for the data set in the table by using the desmos graphing calculator.
Solution:
The general form of least-squares regression line is:
Where, m is the slope and b is the y-intercept.
By using the desmos graphing calculator, we get
Substitute these values in (i).

Answer:
94.985in^2
Step-by-step explanation:
Given data
Diameter= 11inches
Radius = 5.5 in i.e 11/2= 5.5inches
The Area of a circle is given as
Area= πr^2
Substitute
Area= 3.14*5.5^2
Area= 3.14*30.25
Area= 94.985 in^2
Hence the area is 94.985in^2
If Jeff has 5 grasshoppers, then he would have 15 crickets because x(grasshoppers)+10=y(crickets), and y(crickets)+5=z(ladybugs), which would leave Jeff with 20 ladybugs.
Hello from MrBillDoesMath!
Answer:
t = i /(Pr)
Discussion:
i = Prt => (divide both sides by "Pr")
i/(Pr) = (Prt)/(Pr)
= (Pr)t/(Pr)
= t (as (Pr)/(Pr) = 1)
Thank you,
