Answer:
0.1513
Step-by-step explanation:
mean= 15.4
SD=4.5
P(20<X<28)
P((20-15.4)/4.5 < Z < (28-15.4)/4.5)
P(1.022 < Z< 2.8 )
From Z distribution table,
P(Z<2.8)= 0.99744
P(Z<1.022)= 0.84614
P(1.022 < Z< 2.8 )= P(Z<2.8)- P(Z<1.022)
= 0.99744-0.84614
= 0.1513
Answer:
1 time
Step-by-step explanation:
Given numbers are 54 and 36.
The greatest common divisor of 54 and 36 = 18
So, .
The least common multiple of 54 and 36 = 108
So, .
As 54 is replaced by and 36 is replaced by
, so after applying the given procedure, the new number is
Now, apply the same procedure, to get and
.
The greatest common divisor of 18 and 108 = 18
So, .
The least common multiple of 18 and 108 = 108
So, .
As is replaced by
and
is replaced by
, so after applying the given procedure, the new number is
which is the same as in equation (i)
Hence, after applying the procedure 1 time after , the obtained number
is the same as
.
