Which set does not contain -3? a)the set of all real numbers b) the set of all integers. c) the set of all whole numbers d) the set of all rational numbers

Solution:

As we know that a set of real number is defined as the set of values in

Hence -3 is a real number.

An integer is defined as a number which is complete in itself or which is not a fraction or decimal.

Hence -3 is an integer.

The set of Whole numbers is defined as the set of values in

But there should not be any fraction or decimal number in the interval.

Hence -3 is not a whole Number.

As we know that a rational number is defined as the set of values which can be written in form, where

Hence -3 is a rational number.

Hence correct option is C

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
