Answer:
B. entire singers
Step-by-step explanation:
A population consists of all subjects that are being studied.
The total number of singers the choral conductor choral conductor has in her choir is 1648.
The 1648 singers refers to the entire subject being studied
Therefore the population is the entire singers.
The correct answer is B.
Answer:

Step-by-step explanation:
We are given that,
The fall of the acorn is represented by the function,

Equating S(t) to 0 gives,

i.e. 
i.e. 
i.e. 
Since, time cannot be negative.
So,
i.e. 1.25 seconds is the time when the acorn will reach the ground.
Thus, from the figure below, we see that,
The interval in which the acorn is in the moving air is
.
Answer:true
Explanation:
24+24=48
48-8=40
40x2=80
80=80!
So it is true.
Answer:
r = -4
Step-by-step explanation:
If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.
This creates the equation 1-8r=13-5r.
Now it's just simple algebra.
You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.
Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.
Ok so <span>Interest = Principle * rate * time
P = 10,000
R = 3% = 0.03
T (we need to solve for t
I = 3600
now we sub..
3600 = (10,000)(0.03)(t)
3600 = 300t -- divide both sides by 300
3600/300 = t
12 = t
check..
I = prt
3600 = (10000)(0.03)(12)
3600 = (300)(12)
3600 = 3600 (correct)
It would take 12 years</span>
