Answer:
a) 18 cm
b) 18
c) 3
The Earl's height is unusual because the z score does not lies in the given range of usual i.e -2 and 2
Step-by-step explanation:
Given:
Mean height, μ = 174 cm
Standard deviation = 6 cm
height of Earl, x = 192 cm
a) The positive difference between Earl height and the mean = x - μ
= 192 - 174 = 18 cm
b) standard deviations is 18
c) Now,
the z score is calculated as:

or

or
z = 3
The Earl's height is unusual because the z score does not lies in the given range of usual i.e -2 and 2
The correct answer would be C) 180 cubic feet.
WORK: 18 x 20 = 360, 6/12 = 0.5... then multiply 360 x 0.5 and you get 180
Given:
Rate of interest = 8% compounded continuously.
Amount = 100,000
Time = 25 years
To find:
The principal value.
Solution:
Formula for amount after continuous compound interest:

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting
in the above formula, we get




On further simplification, we get

Therefore, the amount 13533.528 is invested.
