Answer:
$23.52
Step-by-step explanation:
So first you would have to find how much each one would be if you were buying one individual book. For that you would do 31.36/4 to get $7.84. Then since you found that for only 1 book, you would need to multiply that by 3 to get $23.52
When you multiply exponents like in the problem, you add them together.
So to find the answer, just subtract the final exponent of 'a' from the original.
6-2=4
The answer should be 4
Answer:
Step-by-step explanation:
From the question we are told that:
Center of hyperbola at ( 6 , 9 )
Focus of hyperbola at ( 11 , 9 )
Vertex of hyperbola at ( 9 , 9)
Equation of hyperbola 
Generally the C and D of the hyperbola equation is mathematically given by
Generally the A and B a of the hyperbola equation is mathematically given by
Therefore with Center,Focus ,Vertex on the same line
Answer:
Step-by-step explanation:
The confidence interval gives a range of values that could contain the population mean.
Confidence interval is written as
Sample mean ± margin of error
Confidence interval does not express probability.
Given that the sample mean home price for city A is $189500 and the sample mean home price for city B is $185000, the difference in the sample mean home prices for both cities is
189500 - 185000 = $4500
Since the margin of error for 95% confidence interval for the difference in average home price between the two cities (A-B) to be $3400, then
The upper limit of the confidence interval is
4500 + 3400 = $7900
The lower limit of the confidence interval is
4500 - 3400 = $1100
Therefore, the correct conclusion is
Beatrice can be 95% confident that the average home price is between $1100 and $7900 more in city A than in city B.
