UPPER AND LOWER BOUNDS
a house is valued at £210000 correct to 2 significant figures
a) what is the lowest possibly value of the house
b) what is the highest possible value of the house

9514 1404 393

Step-by-step explanation:

Essentially, you add or subtract 5 in the place where there would be a third significant digit.

Technically, you can't add 5,000, because that would round up to £220,000, so you can only add 4,999. (If you feel the need to take it to the penny, you can also add 0.99.)

a) lowest: £210,000 -5,000 = £205,000

b) highest: £210,000 +4,999 = £214,999

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
