Edgeunity. these two graphs show the same data. what is
different about the two graphs?
o the vertical scale
o the horizontal scale
the width of intervals
the starting values of the intervals

answer:

step-by-step explanation:

recognize, describe, and calculate the measures of location of data: quartiles and percentiles.

for most of the work you do in this book, you will use a histogram to display the data. one advantage of a histogram is that it can readily display large data sets. a rule of thumb is to use a histogram when the data set consists of 100 values or more.

a histogram consists of contiguous (adjoining) boxes. it has both a horizontal axis and a vertical axis. the horizontal axis is labeled with what the data represents (for instance, distance from your home to school). the vertical axis is labeled either frequency or relative frequency (or percent frequency or probability). the graph will have the same shape with either label. the histogram (like the stemplot) can give you the shape of the data, the center, and the spread of the data.

the relative frequency is equal to the frequency for an observed value of the data divided by the total number of data values in the sample.(remember, frequency is defined as the number of times an answer occurs.) if:

f = frequency

n = total number of data values (or the sum of the individual frequencies), and

rf = relative frequency,

then

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
