Those shapes are congruent
The mean is the sum of all 12 numbers divided by 12, which is 578.25 ~ 578.3. The variance is calculated by subtracting each score from the mean, squaring, and adding all such squares. Then divide by the number of terms (12) to get 68572.35. Take the square root to get the standard deviation, which is 261.9. So the correct answer is B.
Answer:
n= 5.57 years
Step-by-step explanation:
Giving the following information:
your final balance on an investment of 270$ invested at 10% was $459.00
<u>To calculate the time passed between values, we need to use the following formula:</u>
n= ln(FV/PV) / ln(1+i)
FV= 459
PV= 270
i= 0.1
n= ln(459/270) / ln (1.1)
n= 5.57 years
Answer:
I would use either a dotted half note for the first measure (equivalent to 3 beats), or use a half note and a quarter note. In the second measure I would use a half note.
