I = PRT/100
I = Simple Interest
P = Principal
R = Interest Rate per period
T = Time ( no. of periods )
Interest = (2500×9.5×3)/100 = 712.50
Answer : $2500 - $712.50 = $1787.50
1.4 decameter because a decameter equals to meter divided by 10
Answer:
The answer is 0.97
Step-by-step explanation:
Hi, we need to use the log properties taking into account that Ln(2) is aprox. 0.69 and Ln(3) is aprox. 1.10. I think you can understand better as we solve it, so here it goes.

Since:


Then

Now, we have everything where we want it, in terms of Ln(2) and Ln(3), now it is easy to solve.


Best of luck.
Answer:
54.56
Step-by-step explanation:
Given:
Mean, u = 48
Standard deviation,
= 4
Test score = 5%
Required:
Find the raw score, X.
Having a test score of 5% means the Zscore has to correspond to 95%, ie, 1 - 0.05 = 0.95.
Thus, 
To get X, use the formula:

= 48 + (4 * 1.64)
= 48 + 6.56
= 54.56
The anxiety test score that would put someone in the top 5% is 54.56
