Answer:
± 4.05
Explanation:
Data provided in the question:
Random sample size = 15
Standard deviation = 8
Confidence level = 95%
Now,
Margin of error is given as:
Margin of error = ± [ ( z × s ) ÷ √n ]
Here,
From standard z table for 95% confidence level z = 1.96
Margin of error = ± [ ( 1.96 × 8 ) ÷ √15 ]
or
Margin of error = ± [ 15.68 ÷ 3.873 ]
or
Margin of error = ± 4.05
It is because he is paying money so it is a expense
Answer:
31%
Explanation:
The current price is $3,863.99
The precious price is $5,599.99
The actual difference in price is $5,599.99 - $3,863.99
=$ 1, 736.00
Percentage decrease will be actual decrease/ original price X 100
= $ 1736.00/ $5,599.99 x 100
=0.31 x 100
=31%
Answer:
GDP for an open economy from the spending approach follows this equation:
GDP = Consumption + Investment + Government Spending + Net Exports (Exports - Imports)
It can also be written as:
GDP = C + I + G + NX (X - N)
The balance of private consumption is simply equal to C, the balance of public spending is G, and the balance of the external sector is net exports or NX.
Answer:
Each grilled cheese costs $1.25
Explanation:
Giving the following information:
Her income is $50 a week. Hamburgers cost $4, and she consumes 10 of them. She consumes eight grilled cheese sandwiches.
To calculate the price of the grilled cheese sandwiches, we need to use the following equation:
Income= cost of hamburgers*number of units + cost of grilled cheese*number of units
50= 4*10 + x*8
10=8x
$1.25= x= grilled cheese
