Answer:
probability that Stu buys a sandwich and gets the bus = 0.35
Step-by-step explanation:
Probability of success of two independent events is the product of the respective probabilities, i.e. the multiplication rule.
P(Sandwich) = P(S) = 0.5
P(Bus) = P(B) = 0.7
Assuming the events are independent,
probability that Stu buys a sandwich and gets the bus
= P(SB) = P(S)*P(B) = 0.5*0.7 = 0.35

Answer:
Explained below.
Step-by-step explanation:
The data provided is for the number of overtime hours worked in one week per employee.
(a)
The probability distribution is as follows:
X Frequency P(X)
0 8 0.042
1 10 0.052
2 33 0.173
3 53 0.277
4 43 0.225
5 25 0.131
<u>6 19 0.099
</u>
<u> 191 1.000
</u>
(b)
Construct the histogram in Excel.
The histogram is approximately symmetric as maximum data is collected in the middle.
Answer:
Step-by-step explanation:
Add together: 2 2/3 hrs and 2 3/4 hrs:
First determine the LCD of these two fractions. The LCD here is 3*4 = 12.
Rewrite the given times using this LCD:
2 8/12 + 2 9/12
Adding 2 and 2 results in 4; adding 8/12 and 9/12 results in 17/12, or 1 5/12.
The final result is 4 + 1 5/12, or 5 5/12.
The movie and dinner together lasted 5 5/12 hrs.
If movie and dinner started at 3:00, dinner would have finished at
3:00 + 5:5/12, or
8:25 p.m. (since 5:5/12 is the same as 5:25).
Finished eating at 8:25 p.m.
