In a class of 30 students, 20 students like Math and 15 like Science. Also, each student likes at least one of the two

subjects. Find how many students like both the subjects. Also,

illustrate the above information in a Venn-diagram.​

1.30

step-by-step explanation:

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

the correct answer is the last option
