Answer:
0.58
Step-by-step explanation:
The first approach to solving the question above is to find the product of 0.3 and 0.4 thus:
Next step is to find the sum of 0.3 and 0.4 thus:
The final step is to find the difference between the two results. Thus:
Therefore, the product of 0.3 and 0.4 subtracted from the sum of 0.3 and 0.4 is 0.58
30.08 divided by 4 is 7.52
Answer:
a number greater than 1 equal to 12 is 6

Missing question: How many executives should be surveyed?
Solution:
Mean = 13 hours
SD = 3 hours
Confidence level = 95%
Mean viewing time within a quarter of an hour = 0.25 = 1.96*3/sqrt (N)
Where N = Sample population
N = {(1.96*3)/0.25}^2 = 553.19 ≈ 554
Therefore, 554 executives should be surveyed to yield such results.
