Answer:
Jack is 31
Lacy is 10
Step-by-step explanation:
x - 9 = 22
since jack is 3 times as old as lacy,
the formula is
3x - 9 = 22
3x = 31
x = 10.3
So Jack is 31
And Lacy is 10
To prove this, subract 9 (years) from both ages
It will give you an approximate sum of 22 years for both their ages, as the question states
Since Lacy is a little over 10 years old, Jack is 31 instead of 30
The formula was taken from someone elses answer so sorry if it`s wrong

Answer:
standard deviation of these expected returns = 0.0295 or 2.95%
Step-by-step explanation:
The detailed step is shown in the attachment
Total amount = Pe^(rt)
where
P=principal
e=2.7182818284...
r=0.035
t=3 (years)
Total amount
= 7565(e^(0.035*3)
=$ 8402.53
There are different data sets that have the same mean, median, and mode. Here's the data sets i got:
Set 1: 2,2,2,3,5,5
Set 2: 0,1,2,2,4,10
The mean for the 1st set is:
2+2+2+3+5+5= 19/6=3.1
The mean for the 2nd set is:
0+1+2+2+4+10= 19/6=3.1
The median for the 1st and 2nd set is:
2.5
And the mode (most common number) for the 2 sets is:
2
Hope this helps!! :-)
Sorry if I took to long, it took me awhile to come up with 2 sets that had different numbers, but had the same mean/median/ and mode.
