Help please
mezya [45]

Answer:

Step-by-step explanation:

Remark

My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)

What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.

zero

n = 0

g(0) = 34 - 5*0

g(0) = 34

One

n = 1

g(1) = 34 - 5*1

g(1) = 34 - 5

g(1) = 29

Two

g(2) = 34 - 5*2

g(2) = 34 - 10

g(2) = 24

Three

g(3) = 34 - 5*3

g(3) = 34 - 15

g(3) = 19

Four

g(4) = 34 - 5*4

g(4) = 34 - 20

g(4) = 19

Answer

0      1       2       3      4

34  29     24     19     14

And how many map squares did we survive more than 29 plant species
denis-greek [22]

Answer:

Hello your question is incomplete attached Below is the missing histogram

answer: 10 map squares

Step-by-step explanation:

There are 10 map squares that did survive more than 29 pant species because from the given diagram we can see that the plant species above 29  are spotted in 4 map squares ( i.e. from spot 30 to 39 ) and 6 map squares ( i.e. from 30 to 49 )

hence the total number of map squares = 4 + 6 = 10 map squares
