A consumer testing service is commissioned to rank the top 3 brands of laundry detergent. A total of 10 brands are to be included in the study. In how many ways can the consumer testing service arrive at the final ranking
Answers
Answer:
120ways
Step-by-step explanation:
This question bothers combination. Combination has to do with selection.
Given
Total number of brands = 10
If we the service is to rank the top 3, this can be done in 10C3 number of ways.
10C3 = 10!/(10-3)!3!
10C 3 = 10!/7!3!
10C3 = 10*9*8*7!/7!3!
10C3 = 10*9*8/6
10C3 = 720/6
10C3 = 120
Hence it will take 120ways for the consumer testing service to arrive at the final ranking
In a class of 125 students, 28 are computer science majors, 52 are mechanical engineering majors, 12 are civil engineers and the rest are general engineering majors. Assume students only have one major. If a student is chosen at random what is the probability they are:
Answers
Answer:
The probability none mechanical engineering majors is 0.03967.
Step-by-step explanation:
Given that,
Total students = 125
Number of students in computer science = 28
Number of students in mechanical engineering = 52
Number of students in civil engineering= 12
Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?
We need to calculate the probability none are mechanical engineering majors
Using given data
None mechanical engineering majors = [tex]\dfrac{125-52}{125}=0.584[/tex]
If six students from the class are chosen at random then
The probability none are mechanical engineering majors will be
[tex]P_{nme}=(0.584)^6[/tex]
[tex]P_{nme}=0.03967[/tex]
Hence, The probability none mechanical engineering majors is 0.03967.

You work on a concrete crew starting a construction project. Once the pouring begins, it must continue non-stop until it is completed. Your crew will work an 8-hour shift along with two other crews. The total project requires 175,000 yards of concrete. Your supervisor estimates that each crew will pour around 1200 yards per hour. How many consecutive days should you plan to work on this project?
Answers
Answer:
I believe it is 6 days.
The total number of days all crew needs to pour concrete is 6 days consecutive.
Work-day based problem:What information do we have?
Total number of crew = 3
Total yards = 175,000
Each crew pour concrete per hour = 1200
Total concrete pour per day = 1200 × 3 × 8
Total concrete pour per day = 28,800 yard
Total number of days crew pours concrete = Total yards / Total concrete pour per day
Total number of days crew pours concrete = 175,000 / 28,800
Total number of days crew pours concrete = 6.076
Total number of days crew pours concrete = 6 days

44
-34
Answers
Answer:
44
Step-by-step explanation:
44÷5 is 8.8 which is greater than 7
Answer:
x=44
Step-by-step explanation:
Divide each number by 5
-44/5 = -8.8
34/5 = 6.8
44/5=8.8
-34/5=-6.8
8.8 is the only one greater than 7 so 44 is the only one that satisfies the inequality
