Answer:
About 2.2 gallons
Step-by-step explanation:
Create the following proportion:
=
Cross multiply.
10.5 x 1 = 10.5
4.75 x X = 4.75x
4.75x = 10.5
Divide both sides by 4.75x.
10.5/4.75 = 2.2

Answer:
10 Values
Step-by-step explanation:
We would use a set of data for illustration
Given the set of numbers:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
Since we have an even number of data, the median is in between 10 and 11.
(1,2,3,4,5,6,7,8,9,10),(11,12,13,14,15,16,17,18,19,20)
Lower Half: (1,2,3,4,5,6,7,8,9,10)
- The median of the lower half is in between 5 and 6. So
is in between 5 and 6.
Upper Half:(11,12,13,14,15,16,17,18,19,20)
- The median of the upper half is in between 15 and 16. So
is in between 15 and 16.
Therefore, we have the [position of the first and third quartiles as:
1,2,3,4,5,,6,7,8,9,10,11,12,13,14,15,
,16,17,18,19,20
There are 10 values in between the first and third quartiles.
Answer:
Step-by-step explanation:
M²N² - MN = MN (MN - 1)
M²N² + MN = MN (MN + 1)
= (MN - 1) * MN * (MN + 1)
= (MN - 1)(MN +1) MN {(a+ b)(a - b) = a² - b² }
= (M²N² - 1²) * MN
= (M²N² - 1)MN
