The owner of a fitness center conducted a survey using 20 people at the center, selected at random. Each person was given 30 seconds to do as many push-ups as possible, and 30 seconds to do as many sit-ups as possible. The data is shown in the graph.

which two statements correctly describe the data?

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

the answer is 8/21

hope this

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
