Answer:
-0.5
Step-by-step explanation:
σM=σ/√N
=9/√36
=9/6
=3/2=1.5
Z=(x-μ)/σ/√N
=(19.5-24)/9/√36
=-4.5/1.5=-3
The probability that the sample mean will be larger than 19.5 = -0.5
P(>19.5)=P(Z>-3)= -0.5
You do 1.2×12, which gives you 14.4% in a year
Answer:
0.5
because it is a standard deviation
The answer is: "
1.543 % " .
or, as a fraction: "
" .
_________________________________________________________Explanation:_________________________________________________________(5/18) out of 18
= (5/18) ÷ (18/1)
= (5/18) * (1/18)
= (5*1) / (18*18)
= 5/324 ;
5 ÷ 324 = 0.0154320987654321 ;
0.0154320987654321 * 100 =
1.543208 % ;

2 goes into 18 nine times.
3 goes into 27 nine times.
