If what you are asking is when they well reach the same amount of money it’s 6 weeks
First of all, 2^n and 3^n are exponentials with different bases, and thus their sum cannot be simplified beyond 2^n + 3^n. In other words, these two functions cannot be combined ino one function (such as 4^n).
You may gain much more insight by graphing 2^n, 3^n and 4^n to determine whether there is truth in the given statement or not.
10% of $125 is $12.50.
Now 20%=2*10%.
So 20% of $125 is $25.
If you were to receive a 20% discount, you'd only have to pay $100 to bag the jump suit.
Answer: x=114

Answer:
Answer:
B
Step-by-step explanation:
First to find the sample mean
Xbar= summation x/n= 40/4= 10
The sample standard deviation is:
S= √summation(x-xbar)²/ n-1
=√6/3= 1.4142
The degrees of freedom
df= N-1= 4-1= 3
For 95% confidence level, critical value of t
t= 3.182
The 95% confidence interval is:
=Xbar plus or minus t' *8/√n
= 10 plus or minus 3.182(1.4142/√4)
= 10plus or minus 2.25
So 7.75 or 12.25
