the chart below summarizes the results of a 5th grade experiment comparing student height to student arm span. which of the following equations would be a suitable equation for a line of best fit for the data in the chart?

height (in.)

42
45
52
48
49
53
59
45
44
60

arm span (in.)
41
43
55
49
49
52
60
44
45
67

a.
y=-x+7
b.
y=-x
c.
y=x
d.
y=x+7

Option: C is the correct answer.

             C.   y=x

We are given a set of data values as:

       Height(in.)       Arm span(in.)

           42                        41

           45                        43

           52                        55

           48                        49

           49                        49

           53                        52

           59                       60  

           45                        44

           44                        45    

           60                       67

on plotting these points we see that the line that best represent these data points is a linear graph and the equation of the line of best fit is:

                                y=x

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
