UPPER AND LOWER BOUNDS
a book has a front and a back and 400 pages. the front and back cover are each 0.9 mm thick, measured to 1 decimal place. each page is 0.13 min thick, measured to two decimal places. calculate the minimum thickness of the book. some working must be shown

51.7mm

Step-by-step explanation:

#Find the minimum bound of the back/front thickness:

-Given that it's rounded to one decimal point, the margin or error will be:

We subtract this ME from the front thickness to get the minimum thickness:

#Find the minimum bound of the pages:

-Given that it's rounded to one decimal point, the margin or error will be:

We subtract this ME from the page thickness to get the minimum thickness:

The minimum book thickness is thus calculated as:

Hence, the minimum thickness of the book is 51.7 mm

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
