You have $50,000 to invest (YAY!). You need $350,000 in the account to retire in 30 years. At what continuously compounded inter

Luden [163]

Answer:

You need to invest at a continuous compound interest rate of 6.701355026%

Step-by-step explanation:

The formula to use is the compound interest formula:A=P(1+r/100)^t

where A=Total amount at the end of the investment period

P=Principal amount

R=Rate of interest

T=Investment tenor/time

Now,

350,000=50000(1+r/100)^30 is what needs to be simplified to 6.701355026%

1. What is the mean to the nearest tenth?

Inessa [10]

Solution: 1. The mean is given below:

$Mean=\frac{\sum fx}{\sum f}$

Where:

$f$ is the frequency

$x$ is the value

$\therefore Mean=\frac{1 \times 7 + 2 \times 1+ 3 \times 3 + 4 \times 2 + 5\times 2}{15}$

$=\frac{7+2+9+8+10}{15} =\frac{36}{15} =2.4$

Therefore, the mean = 2.4

2. The mean is given below:

$Mean = \frac{8+11+23+15}{4}$

$=\frac{57}{4}$

$=14.3$

I am not understanding why your teacher 14.3 is wrong. Please check whether the weight of 4 pumpkins is correct or not.

3. We are given that on average 5 passengers will board the bus at each of the 6 stops.

Let x be the number of passengers board the bus at the sixth stop.

Therefore, the average is:

$\frac{3+7+5+6+2+x}{6} =5$

$23+x=30$

$x=30-23$

$x=7$

Therefore, 7 passengers need to board the bus at the sixth stop for Leah's prediction to be true.
