Answer:
38.3 square inches
Step-by-step explanation:
The product of length and width gives the area of a rectangle:
area = (9.00 in)·(4.25 in) = 38.2500 in²
Each contributor has 3 significant digits, so your rounding rule requires the answer be rounded to 3 significant digits:
area ≈ 38.3 in²

Answer:
The probability that 8 mice are required is 0.2428.
Step-by-step explanation:
Given : A scientist inoculates mice, one at a time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.
To find : What is the probability that 8 mice are required? The probability that that 8 mice are required is nothing ?
Solution :
Applying binomial distribution,

Where, p is the probability of success 
q is the probability of failure q=1-p, 
n is total number of trials n=8
r=3
Substitute the values,




Therefore, the probability that 8 mice are required is 0.2428.
