Answer:

Step-by-step explanation:

First find the derivative of sin-1x.

This is a standard derivative and it is 1 /√(1 - x^2)

This is the slope of the graph at x.

Slope at x = 0 = 1 /√(1 - 0^2)

= 1/1 = 1,

Use the value of the linear correlation coefficient to calculate the coefficient of determination. What does this tell you about

LenKa [72]

Answer:

Coefficient of determination = 0.149769

Step-by-step explanation:

We are given the following in the question:

Coefficient of correlation, r = -0.387

We have to find the coefficient of determination.

Coefficient of determination =

$r^2 = (-0.387)^2 = 0.149769 = 14.98\%$

Coefficient of determination:

It tells us about the variation explained in the model.
This correlation of determination tells that 14.98% of the variation is explained in the model that is we can say that the independent variable explains 14.98% changes or prediction in the dependent variable.
It ranges from 0 to 1 and a correlation of determination of 1 means that the dependent variable is 100% predicted by the independent variable.
Correlation of determination of 0 means that the dependent variable cannot be predicted by the independent variable.

What is the common difference in the sequence 8, 16, 24, 32.....?

Sergio039 [100]

To find the common difference in the sequence 8, 16, 24, 32.... we must find what the difference between two consecutive terms is. A simple way to do this is to find the difference between the first term and the second term. That means that we have to do the second term - the first term. That means we do 16 - 8 which gives us that the common difference is 8.

X + 1 = 2 x +1 In the equation above, which choice is a possible value of x + 1?

kaheart [24]

Answer:

Step-by-step explanation:

First, we need to find the solution to the system of equations. If x+1 = 2x + 1 , solving for x we have that: x=0.

Given that x=0, the possible value of x+1 = 0 +1 = 1.
