Step-by-step explanation:
1.828 x 10 ^3 is standard for 1828
<u>Answer:</u>
The range of the function y = 2cos x is -2 <y < 2 .
<u>Step-by-step explanation:</u>
We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,
since ,
cos (x + 2π) = cos x
So, the range of the function y = 2cos x is -2 <y < 2 .
From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).
<h3>What is the correlation coefficient?</h3>
The correlation coefficient is a measure of how similar two datasets are acting.
When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.
One data increases and other data starts to decrease in the opposite direction.
When the correlation coefficient comes out below 0, values are negatively correlated.
The correlation shown by the graph is negative.
From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).
