Answer:
x (smallest to largest) = 0,45 ,55
y (smallest to largest) = 0,10,40
Step-by-step explanation:
(hours) Dinghy Rowboat Labor Available
Metal Work 2 3 120
Painting 2 2 110
Let x represent the number of dinghies the company can manufacture and y represent the number of rowboats.
So, total hours for metal work =
So, total hours for Painting =
So, equation becomes:
Plot the inequalities
Refer the attached figure
So, the vertices of the feasible region are (0,40),(45,10) and (55,0)
So, x values are 0 , 45 and 55
x represents the number of dinghies
So, x (smallest to largest) = 0,45 ,55
y values are 40,10,0
y represent the number of rowboats.
So, y (smallest to largest) = 0,10,40
Answer:
(b)
Step-by-step explanation:
1 male named Bart (b)
3 females named Charlene(c), Diana(d), and Erin(e).
Since there is replacement, the possible samples are:
bb, bc, be, bd, cb, cc, cd, ce, db, dc, dd, de, eb, ec, ed, and ee.
Total Number of pairs = 16
Event of picking 2 males:bb
Event of 1 male:bc,cb,bd,db,be,eb
Event of picking 0 males:
cc, cd, ce, dc, dd, de, ec, ed, and ee.
b. The mean of the sampling distribution
c. No; the proportion of males is while the mean is
.
B. No, the sample mean is not equal to the population proportion of males. These values are not always equal, because proportion is an unbiased estimator.
