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.

Kylie is packing books into boxes for shipping. Each full box must not be heavier than 6lg. The books she is packing weigh 750g

Leona [35]

Kylie can add 6 books more to fill the box.

Step-by-step explanation:

Given,

Weight limit of each box = 6kg

1 kg = 1000 grams

6 kg = 1000*6 = 6000 grams

Weight limit of each box in grams = 6000

Weight of each book = 750 grams

Already picked weight = 1500 grams

Let,

x be the number of books she can add.

Weight of one book*number of books + Already packed weight = Weight limit of each box in grams

750x + 1500 ≤ 6000

$750x\leq 6000-1500\\750x\leq 4500$

Dividing both sides by 750

$\frac{750x}{750}\leq \frac{4500}{750}\\x\leq 6$

Kylie can add 6 books more to fill the box.
