Answer: 3.22
Explanation:
Given that;
mean = 2.5 min
standard deviation = 0.25 min
now to get the value of X required, we say
z = (x - u) / a
where z is the distance from the mean measured in the standard deviation units, x is the value we are interested in, u is the mean distribution, a is the standard deviation of the distribution.
the time delay should be just enough to allow 99.8% of the cabinets to dry completely = 99.8/100 = 0.9980
first we determine an appropriate z value.
Using the standardized normal tables,
value of z for approximately 0.9980 is 2.88
so using our initial equation z = (x - u) / a
we substitute the value
z = (x - u) / a
2.88 = ( x - 2.5) / 0.25
2.88 * 0.25 = x - 2.5
0.72 = x - 2.5
x = 0.72 + 2.5
x = 3.22
Answer:
b) 5
Explanation:
W TP MP MRP
1 100
2 190 90 900
3 270 80 800
4 340 70 700
5 400 60 600
6 450 50 500
7 490 40 400
8 520 30 300
the marginal product of n labor = (total product of n labor - the total product of p labor)/(n-p)............(n>p)
Marginal revenue product = marginal product*price
the firm employ input up to marginal revenue product equal to the wage
MRP = wage or closest lower wage
where W = 5
the firm will higher 5 workers.
If the firm can increase its profit by increasing its output then the firm is not producing at where the marginal cost is equal to the marginal revenue. A profit-maximizing firm in a competitive market will produce its output at the point in which MC=MR.
