Answer:
$55,085.44
Step-by-step explanation:
The formula for the account balance is ...
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years. Using the given values, we find the balance to be ...
A = $21,000(1 +0.082/2)^(2·12) = $21,000(1.041^24) ≈ $55,085.44
The balance is $55,085.44 after 12 years.
Answer:
0.40517 is the probability
Step-by-step explanation:
The first thing to do here is to calculate the corresponding z-score
Mathematically;
z-score = x-mean/SD
from the question,
x = 78, mean = 75 and SD = 12.5
Plugging these values in the z-score equation, we have;
z-score = (78-75)/12.5 = 3/12.5 = 0.24
So the probability we want to calculate is that;
P(z < 0.24)
we can get this by using the standard normal distribution table,
The value according to the table is;
0.40517
73 is a prime number because its only factors are 1 and itself
The answer to the squence is either d or a i believe
A regular octagaon has 8 equal sides
so it only makes sense to say that the other side of an octagon would be 4 inches too!
But if you want to know the total length, multiply 8 x 4 = 32 inches!
BUT THIS IS ONLY IF ITS A REGULAR OCTAGON
otherwise it can't be really determined since I don't know its symmetry or the angles!!
Hope I answered your question! :)
