What is the average rate of change over the interval [0, 4]?

choli [55]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Given:

Interval, [0, 4]

Required:

Average range of change over [0, 4]

SOLUTION:

Find f(0) and f(4) from the graph:

$f(0) = 0$ (when x = 0, y = 0)

$f(4) = 3$ (when x = 4, y = 3)

Average rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

$a = 0, f(a) = 0$

$b = 4, f(b) = 3$

Plug in the values into the formula for average rate of change.

$= \frac{3 - 0}{4 - 0}$

$= \frac{3}{4}$

Average rate of change $= \frac{3}{4}$

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.

How do i get x 0.15x+45=150

crimeas [40]

Subtract 45 on each side so it would be
0.15X=104 then divide both sides by 0.15X

then X= 700
