WHICH ONE IS NOT PROPORTIONAL PLEASE HELP

Mechanical pencils are sold in a package of 4 pencils for $3.52. Which statement is not proportional to this?

a single pencil for $0.88

two packages of 4 pencils for $7.04

Buy one package, get the second 50% off.

One small package, containing 2 pencils, costs $1.76.

Buy one package, get the second 50% off is proportional.

Step-by-step explanation:

4 divided by 3.52 is .88, so that is the base amount.

We know that a single pencil is .88, so that is right.

To find two packages, you would multiply one package by 2 (3.52 x 2)

To find the price of two pencils, you multiply the price of one pencil by two (.88 x 2) but is 1.76

The only one that does not fit is the buy one get one 50% off.

y=mx+b is the final answer!   : )

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
