Answer:
Step-by-step explanation:
<u>Use compound interest formula</u>
- A = P(1 + r)^(nt), where A- future amount, P - invested amount, r- interest rate, t- time, n- number of compounds per year
<u>Given:</u>
- P = $2975
- r = 4% = 0.04
- t = 2.5 years
- n = 1
<u>Substitute the values and calculate:</u>
- A = 2975(1 + 0.04)^2.5 = 3281.48
Correct choice is B
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of a circle into center radius form is equal to
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
therefore
the center is the point 
the radius is 
using a graphing tool
see the attached figure
Answer: The sample portion would less closely model the population proportion
Answer:
50000000000 if your combining them both or if separate Q1: 25000000 Q2: 2000
Step-by-step explanation:
2.5(10^7)(2(10^3))
=25000000*2000
=2.5*10000000*2*1000
=(2.5*2)*(10000000*1000)
=5*10000000000
=50000000000
If separate:
question 1:
2.5(107)
=2.5*107
=2.5*(10*10*10*10*10*10*10)
=25000000
question 2:
2(103)
=2*103
=2*(10*10*10)
=2000
I hope this helps!
