The rule for the nth terms is: a_n=13n-5
Further explanation:
First of all we have to decide whether it is an arithmetic sequence or geometric sequence. It is decided based upon common difference or common ratio.
common difference is the difference between two consecutive terms of an arithmetic sequence while common ratio is the ratio between consecutive terms of a geometric sequence.
Here
Common difference:
As the common difference is same, the given sequence is an arithmetic sequence
The general formula for arithmetic sequence is:
Here
a1=8
d=13
The rule for the nth terms is: a_n=13n-5

Answer:
x =120
60,60,120,120
Step-by-step explanation:
The sum of the angles is 360
x + x+ 1/2x + 1/2x = 360
Combine like terms
3x = 360
Divide each side by 3
3x/3 =360/3
x =120
The 4 angles are 120, 120,60,60
From least to greatest
60,60,120,120
<u>Answer-</u>
<em>The </em><em>exponential model</em><em> best fits the data set.</em>
<u>Solution-</u>
x = input variable = number of practice throws
y = output variable = number of free throws
Using Excel, Linear, Quadratic and Exponential regression model were generated.
The best fit equation and co-efficient of determination R² are as follows,
<u>Linear Regression</u>
<u>Quadratic Regression</u>
<u>Exponential Regression</u>
The value of co-efficient of determination R² ranges from 0 to 1, the more closer its value to 1 the better the regression model is.
Now,
Therefore, the Exponential Regression model must be followed.
Answer:
1 x 13 or 13 x 1
Step-by-step explanation:
13 is a prime number
I think that you divide 49 divided by 4, since a square has four sides.
