Answer: 13.5
Step-by-step explanation: You would plug 3 in for x. The expression would then be 3(4.5). This is equivalent to 13.5 when simplified.
Answer: I'm confused. What are you asking here?
Step-by-step explanation:
The inequality of the given question is x+2y ≥ 150
Step-by-step explanation:
Given,
The mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together.
And, he needs to obtain 150 to achieve the grade.
To find, the inequality to student mark
Let,
The student got x in Term 1 and y in Term 2.
To be passed, he needs to get x+2y
So, the requited inequality will be x+2y ≥ 150
Answer:
The boat would travel 6.75 miles in a 1/2 hour.
Step-by-step explanation:
If the boat travels 27 miles in 2 hours, you would take 27 and divide it by 2 to find out how many miles it travels in 1 hour. (27/2= 13.5 miles). Then you would take 13.5 miles and divide it by 2 again to find how many miles it traveled in 1/2 an hour. (13.5/2 = 6.75 miles).
Answer:
b. A driver with an 8-minute commute
d. A bicyclist with a 6-minute commute
Step-by-step explanation:
X = driver to work time (Normal)
Y = bicycle to work time (Normal)
<u>Driving</u>
1) If x = 45
ii) If x = 8
<u>Bicycle</u>
i) If y = 44
ii) If y = 6
The event at driving commute time x = 8 and time bicycle y = 6 are the most unusual time. this is because they are 3 standard deviation below the mean time of respective events
- driver with an 8-minute commute
- A bicyclist with a 6-minute commute
