3 < sqrt(12) < 4
6 < sqrt(40) < 7
So the only integers between those square roots are 5 and 6
Add them together.
If you need it into a decimal or would be .3
Given that Antonia and Carla have the same percentage of marbles and Antonia has 4 green marbles out of 16 marbles , to calculate the number of marbles that Carla has that aren't green we proceed as follows;
let the total number of Carla's marbles be x;
the percentage of green marbles that Antonia has is:
4/16×100=25%
since they have the same percentage then:
number of green marbles Carla has is 10:
this is 25% of x, hence:
10/x×100=25
1000/x=25
1000=25x
thus
x=1000/25
x=40
Carla has a total of 40 marbles. Thus the number of marbles which are not green will be:
40-10=30 marbles
Answer:
B
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 2, 4 ]
f(b) = f(4) = 16 ← from graph
f(a) = f(2) = 4 ← from graph
average rate of change = 
= 
= 6
