Answer:
9
Step-by-step explanation:
SV=Total
ST=part of the length
so, =14-5=9
Answer:
A.
Step-by-step explanation:
(23 * 5) represents the total number of 6th graders.
-s represents the number of students who were absent.
(23 * 5) - s represents the number of students in the museum.
Answer: it’s a
Step-by-step explanation:
Answer:
The total cost will be $60 dollars.
Step-by-step explanation:
If the adults tickets are $20 and the children's are 50% less
$20 × 0.5 = $10
so with two adults and two kids
20 + 20 + 10 + 10 = $60
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.
