Answer:

C) -0.89 is correlation coefficient.

Step-by-step explanation:

Given: data on graph.

TO find : what is the correlation coefficient of the linear fit of the data shown below, to the nearest hundredth.

Solution : We have given a graph

We can see from the graph in which values on x axis is increase and values on y axis decreases , as we can say correlation coefficient is negative but not perfect negative .

Therefore, C) -0.89 is correlation coefficient.

Answer:

$\sqrt{29}$ =5.385 (must look at the requirement of the test as how many decimal...)

Step-by-step explanation:

the squared is equal to 29 means area=29

The exponential function, f(x)=2^x, undergoes two transformations to g(x)=3x2^x+5. How does the graph change? Select all that ap

Shalnov [3]

Answer: Options A and C.

Step-by-step explanation:

The parent exponential function has the form:

$f(x)=b^x$

This can be transformated as following:

When you multiply the function by a factor <em>a</em> ( $a*f(x)$ )<em> </em>and <em>a>0 </em>, then the function is vertically stretched.

When you add a number <em>k</em> to the parent function, the function is shifted up ( $f(x)+k$ )

The parent function given in the problem is:

$f(x)=2^x$

To obtain the function $g(x)=3*2^x+5$ , the parent function is multiplied by a factor 3 (which is greater than 0) and the number 5 is added.

Therefore, the graph is shifted up and vertically stretched.
