3 because the middle of 2 and 4 is three so three is the midpoint
F(x) and g(x) are common fractures
Yuh??
Answer:
First answer is 14
Second answer is 25
Step-by-step explanation:
Median is the middle ( 1 2 3 4 5 the median would be 3)
You start at 2 and end at 27
List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)
In this case there are two 14 & 15
14+15=29 29÷2=14.5
Since there are no decimal answers you are left with 14
Range you take the two end numbers and subtract them (27 & 2)
27-2=25
Hopefully this helps!
Answer:
6.1 gallons of 100% antifreeze and 48.9 gallons of 10% antifreeze
Step-by-step explanation:
Let the amount of 100% antifreeze be x gallon
let the amount of 10% antifreeze be y gallon
total amount to drum = 55 gallons
therefore x + y = 55 -------------------------------Eqn 1
100%(x) + 10(y) = 20%(55)
x + 0.1y = 11--------------------------------------Eqn 2
Both equations are solved simultaneously
From eqn 1 x = 55-y
Substitute x = 55-y into eqn 2
55-y+0.1y = 11
collecting like terms
44 = 0.9y
y = 48.88889
x = 55- 48.88889 = 6.11111 gallons
Therefore 6.1 gallons of 100% antifreeze and 48.9 gallons of 10% antifreeze
