Answer:
36π
Step-by-step explanation:
d= 6 in
r= d/2=6/2= 3 in
volume of sphere= 4/3πr^3
=4/3 ×π×3^3
=36π in^3
Answer:
21.759
Step-by-step explanation:
Given that :
Mean (m) = 25
Standard deviation (s) = 12.5
Sample size (n) = 40
α = 90%
The confidence interval is obtained using the relation:
Mean ± Zcritical * s/sqrt(n)
Zcritical at 90% confidence interval = 1.64
25 ± 1.64 * (12.5/sqrt(40))
Lower boundary : 25 - 1.64(1.9764235) = 21.75866546
Upper boundary : 25 + 1.64(1.9764235) = 28.24133454
(21.759, 28.241)
Hence, lower bound of confidence interval is : 21.759
Where’s your z? incomplete question
Answer:
The correct option is;
C diseconomies of scale; coordination problems
Step-by-step explanation:
Dis-economies of scale is in effect where the average cost of production of firm increases as it increases its inputs towards producing more. That is as the production rate increases, the unit cost of production also increases
Increase in the mean cost of production as the production rate increases is an indication of diminishing returns to increasing scale of production
Dis-economies of scale can be caused by Coordination problems
Difficulties in Co-ordination and monitoring . Where there is growth, the monitoring and coordination requirements becomes more complex, there is also the tendency for increased inefficiency and increase in average cost as the firm expands
Answer:
x=15
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
