Step-by-step explanation:
Mei runs 6 days each week.
=> Mei runs 18 days in 3 weeks.
Since she ran 92.16 miles in 18 days,
She ran 92.16 miles / 18 days
= 5.12 miles/day.
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:
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.

What does 9 + 15 = in distributive property to factor out the greatest common factor?
Answer:
3(3+5)
Step-by-step explanation:
first, you have to find the greatest common factor of 9 and 15, which is 3.
then, you have to do:
9/3 = 3
15/3 = 5
so if you factor out the 3, you get 3(3 + 5)

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
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

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?
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

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

The price of a shirt is usually £45. During a sale the prices in the shop are reduced by 2 5 . How much is the shirt in the sale?
Answer:
£27
Step-by-step explanation:
From the above question, we know that:
The price of a shirt is usually = £45. During a sale the prices in the shop are reduced by 2/5 .
Hence, the amount that the cost of tht shirt is reduced by is :
£45 × 2/5
= £18
The cost of this shirt in the sale is calculated as:
£45 - £18
= £27

sin²x = 2-2cosX
Step-by-step explanation:
sin²x = 2 - 2cosx
1 - cos²x = 2 - 2cosx (because sin²x + cos²x = 1)
cos²x - 2cosx + 1 = 0
(cosx - 1)² = 0
cosx - 1 = 0
cosx = 1
Hence x = 0.
