In a multiple regression problem involving two independent variables, if b1 is computed to be +2.0, it means that:
Group of answer choices:
A. the estimated mean of Y increases by 2 units for each increase of 1 unit of X1, without regard to X2.
B. the relationship between X1 and Y is significant.
C. the estimated mean of Y increases by 2 units for each increase of 1 unit of X1, holding X2 constant.
D. the estimated mean of Y is 2 when X1 equals zero.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

c) yes, because of asa or aas

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
