Last year, Jay was 96 inches tall. This year, he is 108 inches tall. What is the percent increase in Jay's height?

12.5%

Step-by-step explanation:

From the information, last year, Jay was 96 inches tall while this year, he is 108 inches tall.

The percent increase in Jay's height will be:

= (108 - 96) / 96 × 100

= 12/96 × 100.

= 1/8 × 100

= 12.5%

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

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
