Given:
speed = distance / time
walking: 3 miles per hour
running 5 miles per hour
for a total of 3 hours.
3t = 5(3-t)
3t = 15 - 5t
3t + 5t = 15
8t = 15
t = 15/8
t = 1 7/8
7/8 * 60 mins = 52.50 minutes
t = 1 hour and 52.5 minutes
It took Stu 1 hour and 52.5 minutes to hike the trail one way.
Answer: Ordinal
Step-by-step explanation:
We know that the ordinal scale is a level of measurement which is used when we are ordering attributes according to their ranks or preferences.
For example : In an exam we arrange position of students as :
First > Second > Third and so on.
Given : A group of women tried five brands of fingernail polish and ranked them according to preference. It means she is arranging the brands in an order .
Thus this is an ordinal level of measurement .
Answer:
in order to convert Celsius to Fahrenheit, you will need to use this formula: F = 9/5C + 32. Therefore, you will need to solve for C or substitute values and solve in that manner. To find Fahrenheit temperature for -20 degrees Celsius, you can just plug it into the formula. Therefore, F = 9/5 (-20) + 32 and F = 28.4. If you were given 59 degrees Fahrenheit you would get: 59 = 9/5C + 32 and this would give you 27 (5/9) = C, after you have plugged the values into the above formula. When you simplify you, you get C = 15.
It is a bit tedious to write 6 equations, but it is a straightforward process to substitute the given point values into the form provided.
For segment ab. (x1, y1) = (1, 1); (x2, y2) = (3, 4).
... x = 1 + t(3-1)
... y = 1 + t(4-1)
ab = {x=1+2t, y=1+3t}
For segment bc. (x1, y1) = (3, 4); (x2, y2) = (1, 7).
... x = 3 + t(1-3)
... y = 4 + t(7-4)
bc = {x=3-2t, y=4+3t}
For segment ca. (x1, y1) = (1, 7); (x2, y2) = (1, 1).
... x = 1 + t(1-1)
... y = 7 + t(1-7)
ca = {x=1, y=7-6t}
Option D. However, despite its many utilitarian benefits, colleges have not always supported the study of philosophy.
Which choice most effectively sets up the information that follows?
- Despite philosophy teaching useful tools for academic and professional achievement, only 18 percent of the American colleges incorporated the course within curriculum, thus indicating their lack of support.
- Hence, Option D is correct. The other options do not express this condition.
