Answer:
Line A
Explanation:
Both lines have different patterns, but they both show that the amount of gallons of water increases as time increases. Line A moves more differently than line B. Line A shows an increase in that water is filling up quicker than line B. If you were to put points on a graph for both lines, you would figure out that the container for line A is filling up more quickly than the container in line B.
Answer:
22?
I'm not sure but i will corect it if i'm wrong
(4x^2 -25) /( 2x+5)
Factorise the numerator
((2x)^2 - (5)^2 ) / ( 2x+5)
Applying the Difference of squares
= ((2x +5)(2x -5))/ (2x+5)
(2x+5) cancels in both numerator and denominator
That implies ,
= (2x-5) , with restriction 2x+5 not equals to 0
or x not equals to -5/2
So the first one is the correct answer
(2x+5) , restriction , x not equals to -5/2
Step-by-step explanation:
Let,
Marks in fourth test = x
We know that
Mean = Sum of observation/Total observation
=> 46 = Sum/3
=> 46 × 3 = Sum
=> 138 = Sum
Now,
=> 50 = Sum of three observation + x/4
=> 50 = 138 + x/4
=> 50 × 4 = 138 + x
=> 200 = 138 + x
=> 200 - 138 = x
=> 62 = x
Hence,
he should score 62 marks in fourth test
