Please assist me with those investment problems

Step-by-step explanation:

The attachment shows the calculator entries and results. It is a matter of putting the given values into the formula and doing the arithmetic.

Option A)

2000×((1 + 0.042/4)^(4×3))

= $2267

Option B)

2000×((1 + 0.038/12)^(12×3))

= $2241

Option A has higher value after 3 years

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

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
