Answer:
Teresa should build 7.5 inches model.
Step-by-step explanation:
Consider the provided information.
Teresa is building a scale model of the JP Morgan chase Tower in Houston.
Her scale model, 1.5 inches represents 61 meters.
The actual building is 305 meters tall,
First find how many 61's are there in 305.
For this divide 305 by 61.
Actual building is 5 times taller than 61. Thus the model should be 5 times taller than 1.5.
multiply 1.5 with 5 gives us:
Hence, Teresa should build 7.5 inches model.
The weight of a plane with 81 gallons of fuel in the tank is about 44 tons
WE need to complete the square on the x and y terms:-
25x^2 - 100x - 9y^2 - 90y = 350
25(x^2 - 4x + ) - 9(y^2 + 10x ) = 350 + 25( ) - 9( )
25(x^2 - 4x + 4 ) - 9(y^2 + 10x + 25) = 350 + 25(4) - 9(25)
25(x - 2)^2 - 9(y + 5)^2 =
25(x - 2)^2 - 9(y + 5)^2 = 225
---------------- -------------- --------
225 225 225
( x - 2)^2 (y + 5)^2
------------- - -------------- = 1 Answer
9 25

Answer:
At least 1537 samples needed to estimate the true average number of eggs a queen bee lays with 95 percent confidence
Step-by-step explanation:
Minimum sample size required can be found using the formula
N≥
where
- z is the corresponding z-score of 95% confidence level (1.96)
- s is the standard deviation (10)
- ME is the margin of error (0.5)
then N≥
=1536.64
Then, at least 1537 samples needed to estimate the true average number of eggs a queen bee lays with 95 percent confidence
