For this Q:
mean=31
st.dev.=0.8
x=32
Calculate z-score:
z=(x-m)/s = (32-31)/0.8=1.25
This z-score value corresponding to the probability of 0.8944

Answer:
.3636363636363636363636363636363636363...so on so forth.
Step-by-step explanation:
repeating
The other dog's age is "x". Rex's puppy is 5 years less than "x". SO...
x-5.
Understand?
4m = 12x + 40
8x + 8x + 12x + 40 + 4m = 360
28x + 40 + 12x + 40 = 360
x = 7
m = 12(7) + 40 = 124
Two, 2 and 7, because 3/11 just equals 0.2727272727..., so the two and seven keep repeating
