The explicit formula for a sequence is

Alexandra [31]

Answer:

Step-by-step explanation:

Let n = 21, and evaluate the expression.

$a_n = -2 + \dfrac{3}{2}(n - 1)$

$a_{21} = -2 + \dfrac{3}{2}(21 - 1)$

$a_{21} = -2 + \dfrac{3}{2}(20)$

$a_{21} = -2 + \dfrac{3}{1}(10)$

$a_{21} = -2 + 30$

$a_{21} = 28$

What is the angle of 3?

dalvyx [7]

Answer:

the angle of 3 is 50

Step-by-step explanation:

What you would do is add 90 to 40 which would get you 130. Then you will subtract 130 from 180 which gets you 50 for angle 1. Since angle 1 is across from angle 3, angle 3 will also be 50.

Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage of the total v

sergiy2304 [10]

Answer:

Step-by-step explanation:

Given that $r = 0.952$

We have coefficient of determination

$r^2 =0.952^2\\=0.906304$

=90.63%

This implies that nearly 91% of variation in change in dependent variable is due to the change in x.

The coefficient of determination is the square of the correlation (r) between predicted y scores and actual y scores; thus, it ranges from 0 to 1.

An R2 of 0 means that the dependent variable cannot be predicted from the independent variable.

An R2 of 1 means the dependent variable can be predicted without error from the independent variable.
