Answer:
Min. 1st Qu. Median Mean 3rd Qu. Max.
3.10 11.55 12.15 15.35 18.45 30.00
Step-by-step explanation:
The five-number summary includes five things that are:
1. Minimum Value
2. First Quartile (Q₁)
3. Median
4. Third Quartile (Q₃)
5. Maximum Value
So,
1. Minimum Value = 3.10
It can be found by arranging the data in ascending order, the first value we will get is the minimum value.
2. First Quartile is the middle value between Minimum value and Median of data after arranging data in ascending order.
First Quartile (Q₁) = 11.55
3. Median is the middle value of the data after arranging them in ascending order.
Median = 12.15
4. The third Quartile is the middle value between Median and Maximum Value of data after arranging data in ascending order.
Third Quartile (Q₃) = 18.45
5. Maximum Value is the largest value of the data or is the last value after arranging the data in ascending order.
Maximum Value = 30.
Percentiles are mostly use in very large data. Here n percent of data shows the nth percentile.
Answer: The required length of each piece of wood is or 9 inches.
Step-by-step explanation: Given that a piece of lumber is feet long is to be cut into 3 equal pieces.
We are to find the length of each piece of wood in feet and in inches.
We will be using the UNITARY method to solve the given problem.
The length of 3 pieces of wood is equal to
Therefore, the length of each piece of wood will be
Thus, the required length of each piece of wood is or 9 inches.
Answer:
x = -10; x = 4
Step-by-step explanation:
Distribute
(3/4)(4c)+(3/4)(16)=2c/9
3c+12=2/9 c
Now subtract 2/9 c from both sides
3c+12-2/9 c=2/9 c-2/9 c
25/9 c+12 =0
Now we need to subtract 12 from both sides
25/9 c+12-12=0-12
25/9 c=-12
Just multiply both sides by 9/25 so we find the value for c
25/9 *(25/9 c)=-12(9/25)
c= -108/25
I hope that's help:0
