stiks02 [169]

The study creates stress in a(0ne) way that might affect muscle cramps.

What is muscle cramps ?

  • Overuse of a muscle, dehumidification, muscle strain or simply holding a position for a prolonged period can beget a muscle cramp. In numerous cases, still, the cause is not known.
  • Although utmost muscle cramps are inoffensive, some may be related to an beginning medical condition, similar as shy blood force.
  • Cramps can have causes that are not due to underpinning complaint. exemplifications include dehumidification, emphatic exercise or lack of muscle use. Muscle cramps are unforeseen muscle condensation.
  • Also called muscle spasms or charley nags, a muscle cramp can be a common symptom of numerous effects, like exercise strain or a medical condition. Muscle cramps generally go down without treatment and can be watched for at home.

The study creates stress in a(0ne) way that might affect muscle cramps. If an elevator falls, fleetly and stops suddenly, that could affect muscle cramps more because of the physical action than by the stress it convinced.

Shreya and Shanice are selling pies for a
Gemiola [76]

Answer:

$26

Step-by-step explanation:

Let blueberry pies = x and lemon pies = y.

4x + 13y = 230

4x + 2y = 76

Using elimination, we see that 11y = 154. Therefore, y = 14.

4x + 2(14) = 76

4x + 28 = 76

4x = 48

x = 12

x + y = 12 + 14 = 26.

$26 is your answer.

Here's an example.  We'll test the last set of data:  10, 15, 16, 16, 18, 19, 21, 25.  The median is the average of the 2 middle data points:  (16+18)/2 = 17.  So far, so good, since the diagram shows a median of 17.
First Quartile:  find the median of 10, 15, 16, 16; it is the average of 15 and 16, which comes to 15.5.  Third quartile:  find the median of 18, 19, 21, 25.  It's 20.  Does the graph show this?  No.  The First Quartile in the graph is 15, not 15.5 (but this is not very far off).  The Third Quartile in the graph is 20, which matches.   So, the fourth set of data might be an answer.  

You must check out the other 3 data sets in the same manner.  Pick the set that is most closely illustrated by the diagram.
