Answer:
0.683
Step-by-step explanation:
We have to find P(-1<z<1).
For this purpose, we use normal distribution area table
P(-1<z<1)=P(-1<z<0)+(0<z<1)
Using normal area table and looking the value corresponds to 1.0, we get
P(-1<z<1)=0.3413+0.3413
P(-1<z<1)=0.6826
Rounding the answer to three decimal places
P(-1<z<1)=0.683
So, 68.3% of the z-scores will be between -1 an 1.
Answer:
Her clay balls weight 0 pound because she doesn't have balls
Pi = 3.14
2*3.14 = 6.28
4*3.14 = 12.56
area = pi [ C/ (2pi)] ^2
C= circumference
area of small = 3.14 (6.28/6.28)^2 =3.14
area of regular = 3.14 (12.56/6.28)^2 = 12.56
12.56/3.14 = 4
The regular pancake is 4 times the area.
