Daniel looks at the prices of 5 guitars. The prices are $137, $159, $127, $188 and $680. These prices contain one extreme value

brilliants [131]

Answer:

D. Mean absolute deviation

Step-by-step explanation:

Median gives us : 159

Range gives us: 680 - 127 = 553

mean gives us :

127+137+159+188+680 = 1291

1291 / 5

= 258.2

MAD gives us the mean deviation (avg change from the mean):

mean

= 258.2

258.2 - 127 =131.2

258.2 - 137 =121.2

258.2 - 159 =99.2

258.2 - 188 =70.2

680 - 258.2

=421.8

Find the mean of the variances:

70.2+99.2+121.2+131.2+421.8 = 843.6

843.6 / 5

= 168.72

Mad = 258.2 +- 168.72

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

nika2105 [10]

Answer:

For systolic pressure data:

$\bar X =127.2\\\\S=17.91668\\\\CV=\frac{17.91668}{127.2}=0.14085$

For diastolic pressure data:

$\bar X =73.5\\\\S=12.54\\\\CV=\frac{73.5}{12.54}=0.17061$

Systolic pressure is slightly less variable, among individuals in the sample, than diastolic pressure.

Step-by-step explanation:

The coefficient of variation is defined as the percentage relative variation of a set of data with respect to its average. And it is calculated like this:

$CV=\frac{\bar X}{S}$

$S =\sqrt{\frac{1}{n-1} \sum_{i=1}^n (x_i-\bar{x})^2$

$\bar X={\frac{1}{n} \sum_{i=1}^n x_i$

For systolic pressure data:

$\bar X =127.2\\\\S=17.91668\\\\CV=\frac{17.91668}{127.2}=0.14085$

For diastolic pressure data:

$\bar X =73.5\\\\S=12.54\\\\CV=\frac{12.54}{73.5}=0.17061$

It is observed that the systolic pressure shows greater standard deviation but less coefficient of variation. This is due to the greater magnitude of its measurement scale.

Systolic pressure is slightly less variable, among individuals in the sample, than diastolic pressure.

Can someone PLEASE ANSWER BOTH THESE QUESTIONS!!!!!!!!

Andreyy89

Answer:

52º, 128º

Step-by-step explanation:

8. Because ∠6 is an opposite angle to ∠5, ∠6=∠5=52º;

9. Because line a//line b, ∠6=∠4=52º, so ∠7=180º–52º=128º
