Answer:
10
Step-by-step explanation:
Add all of the numbers up and divide by the amount of numbers there are. You subtract for the negatives.
Answer:
False
Step-by-step explanation:
lets find out..
x - 3y < 1.....check (2,-1)....x = 2 and y = -1
now we sub
2 - 3(-1) < 1
2 + 3 < 1
5 < 1.......so is 5 less then 1 ? NO, it is not...so (2,-1) IS NOT a solution

Answer:
<em>The per-pupil spending will be approximate $8,300 in 4 years</em>
Step-by-step explanation:
<u>Exponential Model</u>
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the current quantity.
An exponential decaying function is expressed as:

Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The statistics of the years 2019-2020 at North Carolina indicate initial spending of Co=10,632 per student. The decaying rate is r=6% = 0.06 per year, thus the exponential model is:


where t is expressed in years.
We are required to know the expected spending for t= 4 years. Substitute t=4:

The per-pupil spending will be approximate $8,300 in 4 years
(2×100)+(3×1)+(4×1/10)+(3×1/1000)
200+3+0.4+0.003
203.401
