Tyler is making a wooden post that is 3.5 feet in length he polices marks one and 1/3 in A part on the post after making 20 marks Tyler says there is between 15 in and 16 in on the post that has not been marked

Tyler is right

Step-by-step explanation:

Given that:

Lenght of wooden plank used = 3.5 feets

Placement of tick marks = 1 1/3 inches apart

Number of tick marks placed = 20

Recall:

1 foot = 12 inches

Hence, length of wooden post in inches :

3.5 * 12 = 42 inches on length

Total length covered by the ticks placed :

1 1/3 inches * Number of ticks placed

1. 333 * 20 = 26.6667 inches

Unmarked length = length of post - length covered by tickmark

Unmarked length = (42 - 26.6666) inches

Unmarked length = 15.3333 inches.

Hence,

Within 15 - 16 inches are yet to be marked.

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.
