Find the range of the following data set. 1 1/4, 5/8, 3/4, 1/2, 1 1/2, 1 3/4 a. 1 b. 1 1/8 c. 1 1/4

C

Step-by-step explanation:

The range is the difference between the largest and smallest values in the data set.

largest = 1 and smallest =

range = 1 - = 1 → C

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
