A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?
iVinArrow [24]
I'll use my own formula (similar to yours tho)

A=P(1+ \frac{r}{n})^{nt}
A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years


so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so

2P=P(1+ \frac{0.12}{4})^{(4*t)}
divide both sides by P
2=(1+ \frac{0.12}{4})^{(4*t)}
simplify
2=(1+ 0.03)^{4t}
2=(1.03)^{4t}
take the ln of both sides
ln(2)=ln(1.03)^{4t}
ln(2)=4tln(1.03)
ln(2)=t(4ln(1.03))
divide both sides by 4ln(1.03)
\frac{ln(2)}{4ln(1.03)}=t
use calculator
5.86244=t

10 men and 12 women will be seated in a row of 22 chairs. What is the probability that all men will be seated side by side in 10
-BARSIC- [3]

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that 10 men and 12 women will be seated in a row of 22 chairs.

Total possible ways to arrange n terms is n!.

Similarly,

Total possible ways to place 22 people on 22 chairs = 22!

\text{Total outcomes}=22!

It is given that all men will be seated side by side in 10 consecutive positions.

Total possible ways to place 10 people on 10 chairs = 10!

Let 10 men = 1 unit because all men will be seated side by side in 10 consecutive positions. 12 women = 12 units because women can any where.

Total number of units = 12 + 1 = 13.

Total possible ways to place 13 units = 13!

Total possible ways to place 10 men and 12 women, when all men will be seated side by side in 10 consecutive positions is

\text{Favorable outcomes}=10!\cdot 13!

The probability that all men will be seated side by side in 10 consecutive positions

P=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}=\frac{10!\cdot 13!}{22!}

Therefore the correct option is 4.

aniked [119]

Answer:

some do not have numbers so I tried to make the linking as easy to understand as possible, with answers in bold.

Step-by-step explanation:

(6x + 6) + (-3 - 4x) = 2x + 3

4) = 12x - 2

(6p + 4) + (-5p + 8) = p + 12

6) = -n + 5

(-8r + 8) + (-7 - 7r) = -15r + 1

8) = 6r - 13

(1 - 6x) + (7x + 3) = x + 4

10) = -12x - 3
