Two typists are comparing their typing speeds. The number of words that typist A can type is given by
the function w = 501, where w is the number of
words typed and is the time, in minutes, spent
typing. The graph shows the number of words that
typist B can type. Which typist can type faster?
Explain.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

60: 45 =12: 9 =4: 3 so the answer is 4: 3
