PLZ HELP ASAP CONVERT THE ANGLE
ExtremeBDS [4]
Answer:
θ = \frac{23}{12} π in radians

Explanation:
We know that:
180° is equivalent to π (in radians).
Therefore, to convert 345° into radians, all we have to do is cross multiplication as follows: 
180° .................................> π (in radians)
345° .................................> ??
345° = (345*π) / (180°) = \frac{23}{12} π in radians

Hope this helps :)

Use the given data to find the best predicted value of the response variable. Ten pairs of data yield requals0.003 and the regre
Arada [10]

Answer:

\hat y=3(2) +2=8

Step-by-step explanation:

Data given

r=0.003 represent the correlation coefficient

bar y =5 represent the sample mean for the y observations

Solution to the problem

We assume that they use least squares in order to find the best regression model. The slope is given by the following formula:

m=\frac{S_{xy}}{S_{xx}}

Where:

S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}

S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}

And the slope on this case is:

m=3

Nowe we can find the means for x and y like this:

\bar x= \frac{\sum x_i}{n}=5

\bar y= \frac{\sum y_i}{n}

And we can find the intercept using this:

b=\bar y -m \bar x=5-(3*\bar x)=2

So the line would be given by:

\hat y=3x +2

And the best predicted value for x=2 would be:

\hat y=3(2) +2=8
