Answer:
95%
Step-by-step explanation:
About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.
P(z1<Z<z2)=P(-2<Z<2)
P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)
P(-2<Z<2)=0.4772+0.4772
P(-2<Z<2)=0.9544
Thus, About 95% of the area is between z2 and z2
If you mean 9% of 153 your answer is 13.77
Answer:
Area = Length x width
Step-by-step explanation:
Answer:
Each side is 8.55
Step-by-step explanation:
The perimeter of a square is given by
P =4s
34.2 = 4s
Divide each side by 4
34.2 /4 = 4s/4
8.55 = s
Each side is 8.55
