Answer: (0.25,0.33)
Step-by-step explanation:
A 99% confidence interval for population proportion is given by:-
, where 
= sample proportion, 
= sample size.
Given: 
A 99% confidence interval estimate of the proportion of adults who use the Internet for shopping:
Thus, a 99% confidence interval estimate of the proportion of adults who use the Internet for shopping = (0.25,0.33)
From 2000 to 2011, there are 11 years. From the given function, we can calculate the profit for a small business at the end of 2011 by substituting 11 to the x of the given equation.
y = (30,000)(1.06)(11)
y = 349,800
Thus, the profit at the end of 2011 is approximately $349,800.
Answer:
22
Step-by-step explanation:
(5x-7 )+(4x-11)=180 ( it equals 180 because those two angles equal 180)
Then add the similar things together
5x+4x=9x
-7-11= -18
9x-18=180, add 18 on both sides to get 9x alone
9x=180, then divide 180 by 9 to get x alone
x=22
Answer:it is 6,930
Step-by-step explanation:
Answer:
Step-by-step explanation:
The demand function is expressed as
D(p )=1150-50p
The supply function is expressed as S(p)=−200 + 40p
Where
p represents the price
A) The equilibrium price is the price at which the quantity supplied and the quantity demanded would be equal. Therefore
1150 - 50p = - 200 + 40p
40p + 50p = 1150 + 200
90p = 1350
p = 1350/90
p = 15
The equilibrium price is $15
b) For quantity demanded to be greater than quantity supplied, the price would be
1150 - 50p > - 200 + 40p
40p + 50p > 1150 + 200
90p > 1350
p > 1350/90
p > 15
The price would be greater than 15
c) if the quantity demanded is greater than the quantity supplied, the prices of the T shirt would increase.
