An olympic swimmer competes in the same events during each long course swim season. a swimmer currently competing on the united states women’s olympic swim team, will swim her best events each year with the hope of continuous improvement. the following table is a record of the swimmer’s best times for the 100 meter freestyle event, measured in long course meters.
long course
season recorded
best time
2005 2: 33.42
2006 2: 24.81
2007 2: 10.93
2008 2: 03.45
2009 1: 58.67
2010 1: 59.17
2011 1: 55.06
2012 1: 55.82
2013 1: 54.81
2014 2: 00.03
create a scatter plot representing the data displayed in the table.
use the scatter plot to determine whether there is positive, negative or no correlation between the data values.
write a conclusion statement regarding the data and the rate of change present in the line of best fit. do not actually calculate the slope or write the equation for the line of best fit.

I don't know if you still need this but here you go

Equation for the line of best fit is given by

f(x)=-4.28402x+0.0875

Step-by-step explanation:

Long Course Season       Recorded Best time

2005                          2:33.42

2006                          2:24.81

2007                          2:10.93

2008                          2:03.45

2009                          1:58.67

2010                          1:59.17

2011                          1:55.06

2012                          1:55.82

2013                          1:54.81

2014                          2:00.03

Since we can see from the scatter plot that it has negative correlation.

Equation for the line of best fit is given by

f(x)=-4.28402x+0.0875

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
