I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.
Width of rectangle = x
Length =3x+7
Perimeter of rectangle = 158cm
2(l+w)=158
2(3x+7+x)=158
2(4x+7)=158
8x+14=158
8x=158-14
x=144/8
x=18
Therefore the width of the rectangle is 18cm
Length=3x+18+7
54+7=61cm
Area=lxw
=61x18
=1098^2
Answer:
C.I = $251.2
Step-by-step explanation:
P = Principal amount = 1600
r = rate of annual interest = 6%
n = period / no. of years = 2.5 years
C.I = (P* (1+r^n))-P
C.I = (1600*(1+0.06)^2.5))-1600
C.I = (1600*(1.06^2.5))-1600
C.I = (1600*1.157)-1600
C.I = 1851.2-1600
C.I = 251.2

Answer:
The value of test statistic is -2.
Step-by-step explanation:
The following information is missing in the question.
The population mean is 12 minutes.
We are given the following in the question:
Population mean, μ = 12 minutes
Sample mean,
= 8 minutes
Sample size, n = 36
Population standard deviation, σ = 12 minutes
Formula:
Putting all the values, we have
The value of test statistic is -2.
