What is the length of PR?

d.9 is the length

The reason is because as we have 2 triangles and 21 is divided by 3 we have proof that 27/3=9.

Hope I helped!

You can use deductive reasoning for this. The angle measures are the same so they are similar triangles. This means that they are proportionate. Because the smaller left side is 1/3 the amount of the bigger one, you can assume that the other side follows the same pattern. The smaller side would be 1/3 the size of the bigger side and 1/3 of 27 is 9.

A sample of blood pressure measurements is taken for a group of​ adults, and those values​ (mm Hg) are listed below. The values
mamaluj [8]

Answer:

Systolic variation coefficient (CVS) = 0.1446 = 14.46%

Diastolic variation coefficient (CVD) =  0.1789 = 17.89%

The variation, with respect to the mean, of the systolic pressure sample is slightly less than the variation of the Diastolic pressures.

Step-by-step explanation:

Systolic Mean (MS) = 127.8

Diastolic Mean (MD) = 73.5

Standard Deviation Systolic (sdS) = 18,486

Standard Deviation Diastolic (sdD) = 13.1508

The coefficient of variation is defined by:

Systolic variation coefficient (CVS) = sdS / MS = 18.486 / 127.8 = 0.1446 = 14.46%

Diastolic variation coefficient (CVD) = sdD / MD = 13.1508 / 73.5 = 0.1789 = 17.89%

Then, it can be concluded that the variation, with respect to the mean, of the systolic pressure sample is slightly less than the variation of the Diastolic pressures.
