The median is 38.5
The lower quartile is 29
There is an outlier (154)
The upper quartile is 70
and
The interquartile range is 70 - 29 = 41
A) (8-8/6-2)=0
B) (3-4/7-3)= -1/4
C) (9-3/6-2)=3/2
D) (5-3/7-7)= 1/0 (not identified)
Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions
Answer: 6
Step-by-step explanation:
Here's the complete question:
Leah has 8 4/7 meters of cloth, which she divides equally among her friends. Each friend 10/7 gets meters of cloth. She distributed the cloth to ---- friends.
Total length of the cloth = 8 4/7m
Number of friends = Unknown
Amount of length gotten by each friend= 10/7
The number of friends that she shred the cloth among will be:
= Total length of cloth / Length gotten by each friend
= 8 4/7 ÷ 10/7
= 60/7 ÷ 10/7
= 6/7 × 7/10.
= 60/10
= 6.
It was shared among 6 friends
