Mary is 14 years old. Her resting heart rate 70 beats per minute. Calculate 50% of Mary maximum heart rate to fine her target heart rate

Answers

Answer 1

Answer:

Mary's target heart rate is 103 beats per minute (bpm).

Explanation:

The maximum heart rate (MHR) is the rate at which the human heart of a given person reaches the highest demands. At rest, the heart rate is about 60 to 80 beats per minute.

MHR = 220 - age

So, for Mary: MHR = 220 - 14 = 206 beats per minute (bpm)

Now we can calculate Mary's target heart rate:

Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)

Hope this helped!

Preliminary, non-experimental, research that gathers information about behavior is called Descriptive research.

Nonexperimental research

Nonexperimental research is research that lacks the manipulation of an independent variable, random assignment of participants to conditions or orders of conditions, or both.

In a sense, it is unfair to define this large and diverse set of approaches collectively by what they are not. But doing so reflects the fact that most researchers in psychology consider the distinction between experimental and nonexperimental research to be an extremely important one. This distinction is because although experimental research can provide strong evidence that changes in independent variables cause differences in a dependent variable, nonexperimental research generally cannot. As we will see, however, this inability does not mean that nonexperimental research is less important than experimental research or inferior to it in any general sense.

(The word consumptionrefers to tuberculosis.) A.) Read the beginning of Jason's argumentative speech on the use of Internet slang and answer the question.The use of acronyms, or abbreviations, is not new. In fact, there are examples of the use of acronyms that date back to antiquity. Ancient scribes had a daunting enough task without having to write out every word. The Christian Church has inscribed the acronym INRI, which stands for the Latin Iesus Nazarenus Rex Iudaeorum ("Jesus the Nazarene, King of the Jews") over the crucifix for centuries. American and European corporations discovered long ago that it is easier to remember three letters than it is to remember three names. During the twentieth century, there was an upsurge in the use of acronyms that corresponded with the introduction of highly technical vocabulary. The tendency to shorten has an established history and many of these abbreviations have even found their way into the dictionary. Today, the use of time-saving abbreviations provides the language of internet and other wireless communication. But should it?
