The difference of the range and the interquartile range of the data set represented by the box plot is _.

10

Step-by-step explanation:

==>The range of the data set is the difference between the largest value of the data set (34) and the smallest value of the data set (16).

Range = 34 - 16 = 18

==>The interquartile range is the difference between the Q3 and the Q1.

Q3 = 29 (the data set value at the end of the box to our right)

Q1 = 21 (the data set value at the beginning of the box on our left)

IQR = 29 - 21 = 8

==>The difference between the range and the IQR = 18 - 8 = 10

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
