Answer:
Step-by-step explanation:
1.
one dollar = $1
2 1/2 = 2.5
$1 / 2.5 = $0.40 or 40 cents
2.
$3.78 / 6 = $0.63 or 63 cents
3.
$1.56 / 20 = $0.078
4.
1 1/2 = 1.5
$1.58 / 1.5 = $1.053
5.
$3.90/5 = $0.79 or 79 cents

If x and y vary inversely, then xy = const.
x = 10, y = 8

Answer:
it will take a programmer about 16.67 times to work before they are fired
Step-by-step explanation:
From the information given;
The transistion matrix for this study can be computed as:
P M X
P 0.7 0.2 0.1
M 0 0.95 0.05
X 0 0 1
where;
The probability that the programmer remains a programmer = 
The probability that the programmer turns out to be a manager = 
The probability that the programmer is being fired = 
Thus, the required number of years prior to the moment being fired for an employee y(P), for programmer and y(M) for manager is represented by ;



y(M) = 
y(M) =20
y(P)=1+0.7y(P)+0.2y(M)
y(P) - 0.7y(P) = 1 + 0.2y(M)
0.3y(P) = 1 + 0.2(20)=1+4
0.3y(P) = 1 + 4
0.3y(P) = 5


Therefore, it will take a programmer about 16.67 times to work before they are fired
