Answer:

The perimeter of the triangle is P=a+b+c

where a, b and c are sides of the triangle.

a=3 3/6 cm

b=9 1/8 cm

c=6 cm

Now a=21/6 cm, b=73/8 cm, c=6 cm

We have to take LCM in order to make the denominator same.

Now, the LCM is 48

21*8/6*8 + 73*6/8*6 + 6*48/48

168/48 + 438/48 + 288/48

= 894/48 cm

Clarence measures the diameter of each tennis ball and a bag with a standard ruler. Unfortunately he uses the ruler and correctl

ollegr [7]

Refer to the figure below.

Assume that there are n correct measurements
$x_{i} , \, i=1,2, \, ... \, n$
Because each measurement has an error of 0.2 in, the actual measurements are
$x_{i} + 2$

From the figure, the analysis indicates that the correct mean is
μ = 3 in = 3*2.54 cm = 7.62 cm
The correct standard deviation is
2.934 in = 2.934*2.54 cm = 7.45 cm

Answer:
μ = 7.62 cm
σ = 7.45 cm
