Answer:
Prof B and Prof D
Step-by-step explanation:
Step-by-step explanation:
From the question we are told that
Sample size 100
Instructor Number of Failures
Prof. A 13
Prof. B 0
Prof. C 11
Prof. D 16
Confidence level= 0.95
From Z table
Z=1.96
Generally proportion for failure is mathematically given as
For Prof A
For Prof B
For Prof C
For Prof D
Generally the average proportional failure is mathematically given as
Therefore having this we calculate for the control limits
Generally the upper control limit UCl is mathematically given as
Upper control limits:
Generally the upper control limit UCl is mathematically given as
Lower limit control limits:
Therefore the Range is 0.0412 to 0.1588
Given the range 0.0412 to 0.1588 Prof B and Prof D are outside the Range making them the correct options
Answer:
D 3,528
Step-by-step explanation:
Multiply 252 seat times the 14 trips will get you 3,528 passengers. (Your answer)
Inequalities help us to compare two unequal expressions. The minimum number of sets of knives Indigo should buy is 8.
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Let the number of sets of knives indigo should buy be represented by x.
Given Indigo needs to order some new supplies for the restaurant where she works and the restaurant needs at least 430 knives. Also, There are currently 269 knives. Now, If each set on sale contains 18 knives the inequality that can represent the minimum number of sets of knives Indigo should buy is,
269+18x≥430
18x≥430-289
18x≥141
x≥7.833
x≥8
Hence, the minimum number of sets of knives Indigo should buy is 8.
