Answer:
27.5
Step-by-step explanation:
tens ones . tenths hundredths thousandths
2 7 . 5 3 9
Rounding to the nearest tenth means we look at the hundredth
3 <5 so we leave it alone
27.539 rounds to 27.5
Answer:
0.0735,0.0179,0.7026
Step-by-step explanation:
Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.
Sample size = 49
Population mean = 78
Population std deviation = 28
Std error of sample mean = 
a)
: N(78, 4)
b) 
(by converting to Z and finding value from Z table)
c) P (x overbar less than or equals 69.6 )
=
d) P (75.8 less than x overbar less than 88 )
=
Multiply 18 ×6 then multiply 4×6 then take the answer of 4×6 and take it away from 18×6
The value 2 / 7 is greater than 4 / 12 is - 1 / 21
<h3>How to perform subtraction in algebra?</h3>
To know the value 2/7 is greater by 4 / 12, we have to subtract 4 / 12 from 2 / 7 .
Therefore,
2 / 7 - 4 / 12 = 24 - 28/84
Therefore,
24 - 28/84 = - 4/ 84 = - 1 / 21
Therefore, it is greater by - 1 / 21
