Answer:

IQR = 5

The IQR covers 50%

Step-by-step explanation:

The interquartile range is the right line of the box minus the left side of the box

UQ - LQ = IQR

8 - 3 = 5

The interquartile range is 5

Now to find the percent in the interquartile range.

The Box divides the data in quartiles or 25%

The dot to the left line is 25%

The left line to the middle is  25%

The  middle to the right line is  25%

The right line to the right dote is 25%

From the left line to the right line is 25% + 25% = 50 %

The IQR covers 50%

If the domain of the function f(x)=2x2- 8is {-2, 3, 5}, then the range is
Simora [160]

Answer:

{0, 10, 42}

Step-by-step explanation:

<em>Domain is set of input values and range is set output values.</em>

For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}

<u>Range is:</u>

  • f(-2) = 2(-2)² - 8 = 0
  • f(3) = 2*3² - 8 = 10
  • f(5) = 2*5² - 8 = 42

<u>Range:</u> {0, 10, 42}

What is the gravity of a location if the mass of an object is 300 kg and it has a weight of 450N ?
kozerog [31]

The gravity is 1.5m\s^2

Further explanation:

The weight of any object is given by the product of mass and gravity of the object

Let

m denote the mass of object

g be the gravity

and

w be the weight

Then the statement can be mathematically written as:

w=m*g

Given

m=300kg

w=450N

Putting the values of m and w into the formula

450=g*300\\g= \frac{450}{300}\\g=1.5\ ms^{-2}

The gravity is 1.5m\s^2

Keywords: Mass, Gravity
