Answer:
0.0025 = 0.25% probability that both are defective
Step-by-step explanation:
For each item, there are only two possible outcomes. Either they are defective, or they are not. Items are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
5 percent of these are defective.
This means that 
If two items are randomly selected as they come off the production line, what is the probability that both are defective
This is P(X = 2) when n = 2. So


0.0025 = 0.25% probability that both are defective
The value of m is 2450
<h3>What is Equation?</h3>
Two or more expressions with an Equal sign is called as Equation.
The given equation is
2(14m/400)=171.5
Distribute 2 with numerator on LHS
28m/400=171.5
14m/200=171.5
7m/100=171.5
Multiply 100 on both sides
7m=17150
m=2450
Hence, the value of m is 2450

Answer:
D
Step-by-step explanation:
when a number is added at the end it results in a vertical transformation
16 x 8 = 128 square feet (area of rectangle)
shaded:
8 x 2 = 16
10 x 1 = 10
1/2 (3)(10) = 15
total shaded area: 16+10+15 = 41 square feet
total non-shaded area = 128 - 41 = 87 square feet
answer
area of the shaded region = 41 square feet
area of the non - shaded region = 87 square feet
