3) 180-32= 148°
4) x = 142°
5) 3x+2x = 90°
5x =90°
x= 90/5
x = 18°
6) 180 = 6x + x
180 +2 = 7x
182/7 =x
26° = x
Answer:
4.
- this shows that the height of 13 year old females in one class is less variable than the other class.
- this means that the height of students in class with range 6 may vary from person to person while that in class with range 3 maybe clustered around one another.
- we're expected to see students of almost same height in class ,with range 3, more than the students in class with range 6.
5.
arranging the values in ascending order
2, 2, 4, 4, 4, 5, 6, 6, 6, 8, 8, 9
median = 1/ 2 [ n/2th term +{ (n/2)+ 1 }th term ]
for n is even
= 1/ 2 [ 6th + 7th term]
= 1/ 2 [5 + 6]
= 5.5
mode = value with highest frequency or the value that appears most frequently In a given set of data.
mode =4, 6
because both 4and 6 appear 3 times in the given set of data which is the highest frequency.
Answer:
Mean: 8,75
Median: 7,5
Step-by-step explanation:
To find Mean
To find the mean data you have to put data all set in order:
3, 4, 6, 6, 9, 12, 15, 15
Then, all of the numbers in the data set added together and then divided by how many numbers in the data that already put in order:
3 + 4 + 6 + 6 + 9 + 12 + 15 + 15 = 70
There are 8 numbers in the data so divide 70 by 8:
70 ÷ 8 = 8,75
----
To find Median
The median is in the middle number of the data that already in order. Which is number 6 and 9.
Median = (6 + 9) ÷ 2
Median = 15 : 2
Median = 7,5
