2. mr. demouy is thinking of an irrational number between 4 and 9. mrs. nelson says that the number must be the square root of 6 . mr. demouy says this isn’t true and there are many irrational numbers between 4 and 9 other than the square root of 6 . is mr. demouy right? if so, give 2 examples that mr. demouy could give and say how you known each number is irrational. if mr. demouy is not right, explain how you know this.

3. multiply the square root of 6 by any whole number that is not 1. is the product rational or irrational?

4. determine whether each number of expression is rational or irrational from the choices below. then explain how you know this.
a) - square root of 4
b) -2 square root of 6
c) square root of 47
d) -2 4/9
e) pi ^2
f) 4lsquare root of 2

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.  

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
