Answer:
The budget for The Twilight Saga: New Moon = $50 million
Explanation:
Let the budget for Twilight Saga: New Moon = T
Let the budget for Harry Potter: The Half Blood Prince = H
We are given the following:
(The budget for Twilight Saga is one-fifth the budget for Harry Potter)
Cross multiplying the equation
5T = H - - - - (1)
H + T = 300,000,000 - - - - - (2) (Together the budgets totaled $300 million)
Next, let us substitute the value of H in equation (2) with equation (1)
(5T) + T = 300,000,000
6T = 300,000,000
Therefore, the budget for The Twilight Saga: New moon = $50,000,000
And the budget for Harry Potter: The Half Blood Prince = $250,000,000
Answer:
option (B) 912 ± 42.6
Explanation:
Data provided in the question:
Standard deviation = 64 square feet
Sample size, n = 15
Mean = 912
Confidence level = 99%
Now,
Confidence interval = Mean ± z[s ÷ √n]
here,
z = 2.58 for 99% confidence level
Thus,
Confidence interval = 912 ± 2.58[64 ÷ √15]
or
Confidence interval = 912 ± 2.58[64 ÷ √15]
or
Confidence interval = 912 ± [ 2.58 × 16.525 ]
or
Confidence interval = 912 ± 42.63
= 912 ± 42.6
Hence,
The answer is option (B) 912 ± 42.6
