Answer:
0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.
The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.
Step-by-step explanation:
Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.
First six not defective, each with 0.98 probability.
7th defective, with 0.02 probability. So
0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.
Find the expected number and variance of the number of components tested before a defective component is found.
Inverse binomial distribution, with 
Expected number before 1 defective(n = 1). So
Variance is:
The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.
Answer:
Each person would receive maximum 0.8 pounds of potato.
Step-by-step explanation:
Given:
Total Amount of Potato = 16 pounds.
Number of people attend reunion = 20
We need to find the largest amount of potato each person would receive.
Solution:
largest amount of potato each person would receive can be calculated by dividing Total Amount of Potato with Number of people attend the reunion.
framing in equation form we get;
largest amount of potato each person would receive = 
Hence Each person would receive maximum 0.8 pounds of potato.
Answer: Circle, in my opinion
Step-by-step explanation:
Trapezoid Formula: (a+b/2)h
Circle Formula: πr*2
Solving a circle requires less steps than solving for a trapezoid would, so in my opinion, finding the area of a circle is easier than a trapezoid.
Hope this helps!
Answer:
The Radius is 6.5 cm.
Step-by-step explanation:
We know that the diameter of a circle is a line that begins on one point of a circle and ends on the opposite side. We also know that the radius is a point on the circle that starts from that point and ends at the center. Therefore, the radius would be half the diameter.
Hope this helped :D!
