Answer: w =40m

dependent variable = w

independent variable = m.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of words typed (w) will be equal to the product of the number of words typed per minute (40) and the number of minutes (m)

w =40m

The dependent variable is w , and the independent variable is m.

Because the output value of w depends of the input value of m.

Consider the volume of a rectangular pyramid, one whose base is not square. Does changing one of the three variables (length, wi

user100 [1]

Let

L------> the length of the base of the pyramid

W-----> the width of the base of the pyramid

H-----> the height of the pyramid

V------> Volume of a rectangular pyramid

we know that

V=(1/3)*[L*W]*H

the three variables are going to have the same influence on the volume

example

case a) let's change the variable L (we reduce the variable by half)

L=(1/2)*L

the new volume is equal to

V new=(1/3)*[(L/2)*W]*H-----> V new=(1/2)*V

the new volume is half the original volume

case b) let's change the variable W (we reduce the variable by half)

W=(1/2)*W

the new volume is equal to

V new=(1/3)*[(W/2)*L]*H-----> V new=(1/2)*V

the new volume is half the original volume

case c) let's change the variable H (we reduce the variable by half)

H=(1/2)*H

the new volume is equal to

V new=(1/3)*[L*W]*H/2-----> V new=(1/2)*V

the new volume is half the original volume

therefore

the answer is

the three variables have the same influence on the volume

How do you choose between mean and median as the best measure for the center of a distribution

slava [35]

The mean is often the default measure of center because it includes every data point, ie its more representative. However, if you have outliers then the mean will be skewed toward the outlier. For example, with home prices, very expensive houses will make the mean larger than it should be if you focused on the main cluster of data. This is why the median home price is often measured and reported (rather than the mean home price).

What is the sum of the interior angles of the polygon shown?

Virty [35]

The sum of the interior angles of the polygon shown is 540 degrees

Solution:

The sum of the measures of the interior angles of a polygon with n sides is:

$Sum = (n -2) \times 180$

From given figure in question,

Number of sides in polygon = 5 ( which is a pentagon )

Therefore,

n = 5

Thus the sum of measures of interior angles is:

$Sum = (5-2) \times 180\\\\Sum = 3 \times 180\\\\Sum = 540$

Thus the sum of the interior angles of the polygon shown is 540 degrees
