The answer to this question is 7 days = a week
Step-by-step explanation:
Formula for compound interest is given by

Where
A is the amount at the end of the period
P is the principal
R is the rate
n is the period
The interest = A - P
From the question
P = $ 3200
n = 3 years
R = 40%
So we have

A = $ 8780.80
<h3>The amount is
$ 8780.80</h3>
The interest is
$ 8780.80 - $3200
<h3>= $ 5580.80</h3>
Hope this helps you
Answer : option A
To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile
Inter quartile range is the middle 50% of the given range of scores.
The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%
From the diagram , we can see that
Upper quartile = 89
lower quartile = 65
So range is 65% to 89%
Answer:
x = 3
Step-by-step explanation:
exponential equation:
nb=a
logarithmic equation: logna=b
If you put in 8 for f(x) your exponential equation is
2x=8
Use the pattern above to change it to a log equation
8 = 2^x
log 8 = log 2^x = xlog 2
log 2^3 = 3log 2 = xlog 2
x = 3
