Answer:
The correct answer is actually around 21%. Are you sure the question wasn't asking what the approximate percent decrease from 85 to 70 was? Because in that case it would be around 17%.
Step-by-step explanation:
Answer:
9.9 years
Step-by-step explanation:
A = P e ^(rt)
Where A is the amount in the account
P is the amount invested
R is the interest rate
t is the time
P = 8500
r =7% = .07
A = 17000
Substituting into the equation
17000=8500 e^(.07t)
Divide each side by 8500
17000/8500=8500/8500 e^(.07t)
2 = e^(.07t)
Take the natural log of each side
ln (2) = ln e^(.07t)
ln(2) = .07t
Divide each side by .07
ln(2)/.07 = .07t/.07
ln(2)/.07 = t
9.902102579=t
Rounding to one decimal place

I'm not 100% positive but if my calculations are right then there is a 7.2% chance that a green bead will be drawn 25 times. I hope that helped.
<h3>-1.5, 0.6, 1.125, 1.4 is the order from least to greatest</h3>
<em><u>Solution:</u></em>
Given that,
A photographer records the amount he changes his shutter speed for each photo he takes
The changes are -1.5,1 1/8 ,3/5 and 1.4
Thus the changes are:
1.5
![1\frac{1}{8} = \frac{9}{8} = 1.125\\\\\frac{3}{5} =0.6\\\\ 1.4](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B8%7D%20%3D%20%5Cfrac%7B9%7D%7B8%7D%20%3D%201.125%5C%5C%5C%5C%5Cfrac%7B3%7D%7B5%7D%20%3D0.6%5C%5C%5C%5C%201.4)
<em><u>Order the changes from least to greatest
</u></em>
Negative numbers are least
Therefore,
-1.5, 0.6, 1.125, 1.4
