Answer:
262 square centimeter.
Formula Surface area = 2(wl + hl + wh)
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.
Answer:
The answer is zero
Step-by-step explanation:
Shortest: 1/4 + 3/10 = 5/20 + 6/20 = 11/20
Longest: 1/2 + 3/5 = 10/20 + 12/20 = 22/20
Difference. 22/20 - 11/20 = 11/20
