Answer:
Step-by-step explanation:
Given data:

standard deviation is 
As distribution is normal in shape and values are symmetrical
The standard deviation rule says that 95% of observation lies between the second standard deviation of the mean
so, approximately only 5% of observation lies outside the interval and normal shape is symmetric. hence approximately 0.15% of observation lies above the interval


almost 0.15% of students spent more amount is 529
Answer:
58 more ml
Step-by-step explanation:
147-89=58 ml.
A= bh(1/2)
a=12(14)(1/2)
a= 168(1/2)
a= 84inches
The absolute value of zero is zero
