Round 1.68 to the nearest whole number

Step-by-step explanation:

1.68 to the nearest whole number is 1.68

If the first digit in the fractional part of 1.68 is less than 5 then we simply remove the fractional part to get the answer.

If the first digit in the fractional part of 1.68 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.

The first digit in the fractional part is 6 and 6 is 5 or above. Therefore, we add 1 to the integer part and remove the fractional part to get 1.68 rounded to the nearest whole number as:  2

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
