A statistician wants to determine the relationship between typing speed, in words per minute, and the time, in minutes, it takes

to type one page of a specific book. Twenty-five trials are completed and the correlation coefficient between typing speed and time is determined to be -0.622. Therefore, slower typing speed was related to greater time. How is the correlation affected if the units for time are changed from minutes to seconds

The way that the correlation will be affected if the units are changed from minutes to seconds is that the correlation will still be the same.

<h3>What is correlation?</h3>

Correlation simply means a statistical measure which expresses the extent to which two variables are linearly related.

From the information, it was stated that twenty-five trials are completed and the correlation coefficient between typing speed and time is determined to be -0.622.

In this case, even when the units for time are changed from minutes to seconds, the correlation won't change. This is because the change in units has no effect on the correlation.

Find the slope of this line 2,2. 6,2
laiz [17]
Slope is rise over run, or y over x. Firstx subtract your y values. Make sure that whichever way you want to subtract them (whether you use 2 - 6 or 6 - 2) that you do the same to the x values. So, 2 - 2 is 0. Now, you could go ahead and do the rest of the equation, but there's really no need. A 0 as the numerator means there's no slope, or zero slope.

What i did wrong in this?
I am Lyosha [343]

i) the least positive coterminal angle can be found by subtracting 2pi from your original angle.  We subtract 2pi because 11pi/3 is larger than 2pi.

So: 11pi/3 - 2pi = 11pi/3 - 6pi/3 = 5pi/3 or \frac{5\pi}{3}

ii) The reference angle is the smallest angle you can make with the x-axis.  Since 5pi/3 is in Quadrant IV, the reference angle is found by:

2pi - 5pi/3 = 6pi/3 - 5pi/3 = pi/3 or \frac{\pi}{3}

iii) 5pi/3 or 300 degrees is found in Quadrant IV.

What is the answer for 5/2 and it is equal to 1/3
Fofino [41]

Answer:

5/2=2.5, while 1/3= aprox 0.333, therefore 5/2 is not equal to 1/3.

Step-by-step explanation:

Here is the long division table for 5/2

 2. 5 0 0

2 5. 0 0 0

− 4      

 1 0    

− 1 0    

   0 0  

 −   0  

     0 0

   −   0

       0

Here is the long division table 1/3 ( to three decimal places)

0. 3 3 3

3 1. 0 0 0

− 0      

 1 0    

−   9    

   1 0  

 −   9  

     1 0

   −   9

       1

An easier way to do 5/2 is to think of 50/2, which is 25, and then add a decimal point, making it 2.5.

An easier way to do 1/3 is to think of it as one third (of one), or 0.333 repeating.
