In a survey of 480 students, 253 indicated that play the piano, 268 indicated that they play the harp and 73 indicated they play the piano and the harp. 1. how many students surveyed play the harp only?

195

Step-by-step explanation:

To find many play the harp only, we need to get the number of students that said they play the harp.

268 play the harp

73 play the harp and piano

Now since we're only looking for the students that only play the harp, we subtract the number of students who play the harp and piano to the students who play the harp alone.

268 - 73 = 195

So 195 Students play the harp.

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.
