Sum of three consecutive odd number is 69 find the prime number out​

23 is the prime number

Step-by-step explanation:

let n, n + 2, n + 4 be the consecutive odd numbers, then

n + n + 2 + n + 4 = 69 ← simplify left side

3n + 6 = 69 ( subtract 6 from both sides )

3n = 63 ( divide both sides by 3 )

n = 21 , then

n + 2 = 21 + 2 = 23 and n + 4 = 21 + 4 = 25

The 3 numbers are 21, 23, 25 with prime number 23

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
