Answer:
The lowest time limit in which 95% of the bugs can be found is 11.22 hours.
Step-by-step explanation:
We are given that X is the time in hours required to find a bug in a software system. Assume that X is normally distributed with mean of 3 and standard deviation of 5.
<em>So, X = time in hours required to find a bug in a software system </em>
X ~ N(
)
The z score probability distribution is given by;
Z =
~ N(0,1)
where,
= mean value
= standard deviation
<em>Let the lowest time limit in which 95% of the bugs can be found = </em>
<em />
Now, we have to find the lowest time limit in which 95% of the bugs can be found, i.e.;
P(
<
) = 0.95
P(Z <
) = 0.95
Now, the critical value of
in the z table which given an area of less than 95% is 1.6449, which means;
= 1.6449
= 3 + 8.22 = 11.22
Therefore, the lowest time limit in which 95% of the bugs can be found is 11.22 hours.

Step-by-step explanation:
ASA or "angle-side-angle" tells us that two triangles are congruent if two angles and the side contained between them are equal. Hence, we are looking for two angles that coincide in echa triangle, this is the case for the triangles in a. and b., and that the side that lies between the two angles is also equal in both triangles, again this is the case for a. and b.
