Answer:
$148.02
Step-by-step explanation:
In the question
Principal = $100, rate(R) = 4% compounded annually, time(T)= 10 years
we know that the formula for compound interest
A= where A is amount
now putting values in the above formula we get
A=
therefore A= $148.024428
rounding off to the nearest penny we get amount as $148.02 and compound interest will be $48.02
Answer:
the probability that the average diameter of those sand dollars is more than 4.73 centimeters is 0.5910
Step-by-step explanation:
Given information:
mean, x = 5
standard deviation, σ = 0.9
number of sample, n = 16
now we calculate the probability that the average diameter of those sand dollars is more than 4.73 centimeters.
P(x>4.73) = P (z > (4.73 - x) / (σ )
= P (z > (4.73 - 4) / (0.9 )
= P (z > 0.203)
= 0.5910
