Alocker combination has two nonzero digits, and digits can be used twice. the first number is 8. what is the probability that the second number is 8?
a. 1/9
b. 1/8
c. 7/8
d. 8/9

nope

step-by-step explanation:

a

step-by-step explanation:

strong negative correlation

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
