FORMATION OF DECUBITUS ULCER:

Decubitus Ulcer, also termed as Bed sores often occur when the pressure of one’s body weight cuts off the blood supply to that organ where the pressure is applied leading to death of tissues.

It is most common among the patients who are bed ridden and among the people who sits or sleeps for a majority amount of time. When an individual is seated or is sleeping for a long time, the body exerts a pressure at the point of contact that is in between the body and the firm surface, like bed or a wheelchair. This would lead to cut off of blood supply to the point where the pressure is applied which would lead to damage of skin and tissues eventually leading to the death of tissues.

Nikolay [14]

Answer:

Multiply 4 by 16

Explanation:

Given

$Rate = 1\ page/4\ minutes$

Required

Select the method that maintains her rate for 16 pages

To get the method for 16 pages, we simply multiply 4 by 16. This is shown below

$Rate = 1\ page/4\ minutes$

Calculate the unit rate

$Rate = \frac{1}{4} page/min$

$Rate = 0.25 page/min$

For 16 pages, it is:

$Rate = \frac{16 page}{4 min * 4}$

$Rate = \frac{16 page}{4 min * 16}$ -- Here, we multiply 4 by 16

$Rate = \frac{16 page}{64\ min}$

$Rate = \frac{16}{64} page/min$

$Rate = 0.25 page/min$

See that the unit rates remain the same.

Other options will give different rates

djverab [1.8K]

Answer:

B. −0.72

Explanation:

The correlation coefficient is a measure of the linear association between two variables.

It is a dimensionless value bettween - 1 and +1. Hence, it does not depend on the units that are used to measure the data.

You can see the formula to calculate the correlation coefficient in the attached picture.

There you see that the numerator containts the sum of the differences of the values of the x-variable with its the mean, multiplied by the sum of the differences of the values of the y variable with its mean, while the denominator contains the square root of the product of the squares of the same differences, thus the units are canceled.

In conclusion, If the teacher changes the units of each variable from hours to minutes, the value of the correlation coefficient between minutes studying and minutes spent on the Internet will not change; it will continue being −0.72.
