Answer:
uniformly distributed random numbers here the MATLAB code to find for any number of people and interval
X = rand
X = rand(n)
X = rand(sz1,...,szN)
X = rand(sz)
X = rand(___,typename)
X = rand(___,'like',p)
where
X = rand returns a single uniformly distributed random number in the interval (0,1).
X = rand(n) returns an n-by-n matrix of random numbers.
X = rand(sz1,...,szN) returns an sz1-by-...-by-szN array of random numbers where sz1,...,szN indicate the size of each dimension. For example, rand(3,4) returns a 3-by-4 matrix.
X = rand(sz) returns an array of random numbers where size vector sz specifies size(X). For example, rand([3 4]) returns a 3-by-4 matrix.
X = rand(___,typename) returns an array of random numbers of data type typename. The typename input can be either 'single' or 'double'. You can use any of the input arguments in the previous syntaxes.
X = rand(___,'like',p) returns an array of random numbers like p; that is, of the same object type as p. You can specify either typename or 'like', but not both.
Answer:
A
Step-by-step explanation:
if you have 3.24 you move the decimal to the left since it is negative. you move it 3 spots to the left. When you get 0.00324
Answer:
Tony = 36 Hours
Chris = 45 Hours
Step-by-step explanation:
let y+9 = Chris's time to build the fence alone
let y = Tony's time
let the completed job = 1
20/y+9 + 20/y = 1
Multiply the equation by y(y+9)
20y + 20(y+180) = y(y+9)
20y + 20y + 180 = y^2 + 9y
40 y + 180 = y^2 + 9y
0 = y^2 + 9y -40y - 180
y^2 - 31y - 180
(y + 5)(y - 36) = 0
y + 5 = 0
y = 0 - 5
y = -5 We reject this answer since we're only interested in the positive answer in terms of work done by two people.
y - 36 = 0
y = 0 + 36
y = 36 hours
So Chris takes y + 9 hours more than Tony
Chris's Time = y + 9
Chris's Time = 36 + 9
Chris's Time = 45 hours
