The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
What is a regression model?A regression model is used to determine the association and correlation between two variables
Using a graphing calculator, the sine regression model of the dataset is:
[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]
To calculate y(30), we substitute 30 for x in the equation.
So, we have:
[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]
Evaluate the product
[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]
Evaluate the difference
[tex]y =20.077 \sin(13.041) + 67.577[/tex]
Evaluate the sine value
[tex]y =20.077 *0.4570+ 67.577[/tex]
Evaluate the product
[tex]y =9.1752+ 67.577[/tex]
Evaluate the sum
[tex]y =76.7522[/tex]
Approximate
[tex]y \approx 76.8[/tex]
Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

On the main floor of the Kodak Hall at the Eastman Theater, the number of seats per row increases at a constant rate. Lucas counts 31 seats in row 3 and 37 seats in row 6. How many seats are there in row 20?
67
61
63
65
Answer:
67
Step-by-step explanation:
There are 65 seats in row 20, option D is correct.
Given that number of seats in row 3 are 31.
Number of seats in row 6 are 37
We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:
Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)
Rate of increase = (37 - 31) / (6 - 3)
Rate of increase = 2
So, the number of seats increases by 2 seats per row.
To find the number of seats in row 20, we can use the rate of increase:
Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))
Number of seats in row 20 = 31 + (2× (20 - 3))
= 31 + (2 × 17)
= 31 + 34
= 65
Therefore, there are 65 seats in row 20.

huh i am very confused
Step-by-step explanation:
The sum to infinity of a geometric series is 4 and the second term is 1. Find the first,third and fourth terms.
Answer:
2, 0.5 and 0.25.
Step-by-step explanation:
The nth term an = a1r^(n-1) where a1 = first term and r = the common ratio.
The sum to infinity = a1/(1-r) for -1 < r < 1.
So we have:
Second term a2 = 1 = a1(r)(2-1) = a1r and
4 = a1/(1 - r)
From the first equation:
a1 =1/r
So substituting in the second equation:
4 = 1/ r / (1 - r)
4 = 1 / r - r^2
4r - 4r^2 = 1
4r^2 - 4r + 1 = 0
(2r - 1)(2r - 1) = 0
r = 0.5
So the first term a1 = 1/ r =1/0.5 = 2.
The third = 1*0.5 = 0.5
and the 4th = 0.5*0.5 = 0.25.
Find the area. Show your work.

Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
infinite solutions
Step-by-step explanation:
you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.
-7(y= 1.5x - 6) which equals the equation below
-7y= -10.5x-42 then combine the other equation
7y=10.5x+42 and that equals
0=0
