***mathtest timed*** given the data set for the length of time a person has been jogging and the person's speed, hypothesize a relationship between the variables. a) i would expect the data to be positively correlated. b)i would expect the data to be negatively correlated. c) i would expect no correlation. d) there is not enough information to determine correlation.

It is definetly not A. I took the test and that is wrong.

Step-by-step explanation:

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
