Arandomized study compared two drugs that are designed to lower a person's triglyceride level. it was found that over a 1-year period, those receiving drug a decreased their triglyceride level by a mean of 69. those receiving drug b decreased their triglyceride level by a mean of 45. to determine whether the results are significant, the data are rerandomized and the difference of the means is shown in the dot plot. what is the best conclusion to make based on the data?

A

Step-by-step explanation:

The mean of the decreased levels of group A is 69.

The mean of the decreased levels of group B is 45.

The difference is means is 69 - 45 = 24.

As seen on the dot plot, a difference of 24 is greater than any differences observed by chance.

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
