The residual for a predicted relative abundance when the rainfall was 3 inches is 1.25. What is the actual relative abundance when the rainfall was 3 inches

The actual relative abundance will be "7.59".

Step-by-step explanation:

The predicted relative abundance for 3 inches rainfall will be:

=

=

The residual will be:

=

=

Now,

The actual relative abundance will be:

=

=

=

Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
