Your formula is wrong
it should be
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years
given
P=200
R=0.04
N=12 (12 months in 1 year)
t=8
A=275.279
round
275.28

Answer: u = (41.659, 36.341)
Step-by-step explanation:
Constructing a 90% confidence interval for mean is given by the formulae below.
u = x + Zα/2 * σ/√n...... This is the upper limit
u = x - Zα/2 * σ/√n........ This is the lower limit.
u = population mean
x = sample mean = 39
σ = population standard deviation = 9
Zα/2 = Z score for a two tailed test with an a level of significance = 1.645 ( for 90% confidence level)
Upper limit
u = 39 + 1.645 * (9/√31)
u = 39 + 1.645 * (1.616)
u = 39 + 2.6590
u = 41.659
Lower limit
u = 39 - 1.645 * (9/√31)
u = 39 - 1.645 * (1.616)
u = 39 - 2.6590
u = 36.341
Answer:
andrew is 1.45833333333... meters tall
Step-by-step explanation:
If pizza is available, then I will eat pizza is my statement - it's conditional in that I will eat pizza if pizza is available.
The converse is pretty much switching the if and then, so I get 'If I eat pizza, then pizza is available', which is true .
