Answer:
50%
Step-by-step explanation:
The question asks who has taken fewer than 19 courses.
So first we look at how many are fewer than 19.
There are 4 that are fewer than 19: 12, 9, 5, 17
So.. 4/8 (8 is the total number of options)
To find the percentage you...

Answer:
joint variation means L (safe load) is directly proportional to both w and d2
inverse proportionality means L = k/l
So the equation is:
L = k(wd2/l)
You are given:
w = 6 in
d = 5 in
l = 12 ft
L = 7666 lbs
7666 = k(6*52/12)
Solve for the constant, k.
7666 = k (6*25/12)
7666 = k (150/12)
7666 = k (12.5)
613.28 lbs/(ft.in3) = k
Use this k-value to solve for L in the last part of the question.
What safe load, L would a beam 3 in. wide, 7 in. deep and 15 ft long of the same material support? (Round off your answer to the nearest pound.)
w = 3 in
d =7 in
l = 15 ft
k = 613.28 lbs/(ft.in3)
Final Safe load = 6010.144 lbs *** Edited for clarity and to fix a multiplication erro
Answer:
x > - 8
Step-by-step explanation:
- 4 ( x - 4 ) < - x + 40
- 4x + 16 < - x + 40
+ 16 - 40 < - x + 4x
- 24 < 3x
3x > - 24
x > - 24 / 3
x > - 8
Answer:
Step-by-step explanation:
Given
Range = 0 to 8 years
Distribution: Uniform Distribution
Required
Determine the mean
The mean of a uniform distribution is calculated as thus:
Where a and b are the range of the distribution
In this case:
So, we have:
