Answer:
The nth term is: 
a40 = 10
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.
The nth term of a sequence is given by:

In which
is the first term and d is the common difference.
1/4,1/2
This means that:

1/4
This means that 
The nth term is:


Then find a40.

So
a40 = 10

<h3>Known</h3>
g(x) = -2x - 11

<h3>Question</h3>
g(-3) = ..?
════════════════════
<h3>Way to do</h3>
#since x inside (x) change into (-3) then it means that you only need to change x into -3
g(-3) = -2(-3) - 11
g(-3) = 6 - 11
g(-3) = -5

Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14
