The first thing to do is to sort the given data from smallest to largest. Doing so leads to this ordered list:
{13, 15, 15, 17, 18, 18, 20, 21, 21, 23, 26, 27, 28, 30, 32, 33, 37, 40}

From this list, we can see which values are between 10 and 19 (inclusive). Those values are {13, 15, 15, 17, 18, 18} which represents 6 values. So the first bar (for the "10-19" group) is going to be 6 units high.

The next group, in the "20-29" group, is this set of values {20, 21, 21, 23, 26, 27, 28} which is 7 items this time. The second bar is 7 units high.

The "30-39" bar will be 4 units high because there are 4 items in the set {30, 32, 33, 37}

There is only one person who is between 40 and 49, and that person is 40 years old. So the "40-49" group has a bar that has height of 1.

The final histogram and frequency chart is shown in the attached image. The frequency chart is optional, but it helps supplement the histogram in my opinion.

How many years would it take to make $500 interest on a 12000 investment at 3% per year
padilas [110]

Answer:

t=1.4\ years

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=?\\ P=\$12,000\\ I=\$500\\r=3\%=3/100=0.03

substitute in the formula above

500=12,000(0.03t)

solve for t

500=360t

t=500/360

t=1.4\ years
