What is the question?
Step-by-step explanation:
Answer:
c. 2b - 3
Step-by-step explanation:
Simplify the following:
-2 b + 4 + 4 b - 7
Grouping like terms, -2 b + 4 + 4 b - 7 = (4 b - 2 b) + (4 - 7):
(4 b - 2 b) + (4 - 7)
4 b - 2 b = 2 b:
2 b + (4 - 7)
4 - 7 = -3:
Answer: 2 b + -3
Answer: ( Min = 0 ,
,
,
, Max = 10 )
Step-by-step explanation:
Given : A random sample of 11 days were selected from last year's records maintained by the maternity ward in a local hospital, and the number of babies born each day of the days is given below:
3 7 7 10 0 7 1 2 5 3 0
We first arrange them in increasing order , we get
0 0 1 2 3 3 5 7 7 7 10
Here , N= 11
Now , we can see that
Minimum value = 0
Maximum value = 10
First quartile
= ![(\dfrac{N+1}{4})^{th}\ term=(\dfrac{12}{4})^{th}\ term = 3^{rd} term =1](https://tex.z-dn.net/?f=%28%5Cdfrac%7BN%2B1%7D%7B4%7D%29%5E%7Bth%7D%5C%20term%3D%28%5Cdfrac%7B12%7D%7B4%7D%29%5E%7Bth%7D%5C%20term%20%3D%203%5E%7Brd%7D%20term%20%3D1)
Second quartile
= Median = Middlemost number = 3
Third quartile
= ![(\dfrac{3(N+1)}{4})^{th}\ term=(\dfrac{36}{4})^{th}\ term](https://tex.z-dn.net/?f=%28%5Cdfrac%7B3%28N%2B1%29%7D%7B4%7D%29%5E%7Bth%7D%5C%20term%3D%28%5Cdfrac%7B36%7D%7B4%7D%29%5E%7Bth%7D%5C%20term)
![= 9^{th} term =7](https://tex.z-dn.net/?f=%3D%209%5E%7Bth%7D%20term%20%3D7)
∴ The required five number summary : ( Min = 0 ,
,
,
, Max = 10 )
50 x .40 = 20
50 - 20 = 30
approx. $30
