If a population has a birth rate of 40 individuals per 1,000 per year and a death rate of 30 individuals per 1,000 per year, how will the population change each year? (assume that the population is below carrying capacity and that there is no immigration or emigration.)a) it will decrease by 70%. b) it will increase by 1%. c) it will increase by 5%. d) it will increase by 70%. e) it will increase by 100%.

Population will increase by 1 %

So option (b) will be correct option

Step-by-step explanation:

We have given birth rate of 40 individuals per 1000 per year

So birth rate in percentage %

And rate rate of 30 individuals per 1000 er year

So death rte in  percentage %

So net change in population change per year = 4-3 = 1 %

So population will increase by 1 % per year

So option (b) will be correct answer

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
