Avideo shop owner wants to find out how many videos are turned in late. he found that of the next 30 videos turned in, 8 were late. if 450 videos are turned in over the next several hours, what is the best prediction for how many will be late?

120

Step-by-step explanation:

8/30 were late, and if the denometer changed from 30 to 450, it must have multiplied by 15. So if you multiplied the bottom of the fraction, you would have to multiply the top too. So 8 x 15 = 120

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

combine all like terms then its just a 2 step equation
