Use Continuous Compound Interest Formula:
A = Pe^rt
A = Future Amount
P = Initial Amount
r = Interest rate
t = Time
%2 = 2/100
= 0.02
A = 500.00e^(0.02)(4)
A = 541.6435338
Round to nearest cent:
A ≈ 541.64 -> Final Answer.
Answer:
mother=m
e=emily
m=4e
m+6=3(e+6)
substitute the first equation into the second.
4e+6=3(e+6)
4e+6=3e+18
4e=3e+12
e=12

Since a circle (assuming it is) has 360degrees in total, you would have to do 360-(23+60+150) which would equal to 137.
(The answer would be 137 degrees.)
The angle of depression from the top of a 150 m high cliff to a boat at sea is 7 degree. How much closer to the cliff must the boat move for the angle of depression to become 19 degree.

ince the exam creator claims that on the same exam, nine times out of
ten, seniors will have an average score within 6% of 80%, that means
there is a 90% confidence interval.
9 / 10 = .90 = 90%
90% = 1.645
1.645 * .9 = 1.4805
Margin of Error - 1.4805
and The margin of error is the distance from x-bar, the center of the
confidence interval ,to the end of the interval. This distance is 6% of
80% which is given by:
<span><span><span>80×6</span>100</span>=4.8</span>
Therefore the margin of error is 4.8% and the confidence interval is:
({80 - 4.8}%, {80 + 4.8}%)
