One spring day, Dylan noted the time of day and the temperature, in degrees Fahrenheit. His findings are as follows: At 6 a. m., the temperature was 56° F. For the next 2 hours, the temperature rose 3° per hour. For the next 3 hours, it rose 4° per hour. The temperature then stayed steady until 6 p. m. For the next 4 hours, the temperature dropped 3° per hour. The temperature then dropped steadily until the temperature was 61° at midnight. On the set of axes below, graph Dylan's data.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

ok thats very interesting

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
