A west Texas city has a population of 9,525. A city council poll revealed that 56% of the citizens want a fireworks display for the upcoming 4th of July celebration. How many of the city's people
want a fireworks display for the 4th of July?

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

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3

the answer is that it is true
