Jaclyn estimates that the square root of 50 in the following way:

50 −−−√ = 225−−√ =2*5 = 10
explain why her reasoning is incorrect. use complete sentences.

(2 points for explaining why it is wrong, 1 point for writing in complete sentences.)

Her reasoning is wrong because she forgot the root of 2. ()

Step-by-step explanation:

We decompose the number into prime factors

50 = 2*25 = 2*5*5 = 2*(5^2)

Now, we apply the square root of the last term

This is equal to:

* =

*5 = 5 = 7.071

Which is the same answer as = 7.071

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
