Answer:
For this case the confidence interval is given by :
Step-by-step explanation:
Data provided
represent the sample mean for the fuel efficiencies
population mean
s=2.51 represent the sample standard deviation
n=601 represent the sample size
Confidence interval
The formula for the confidence interval of the true mean is given by:
(1)
The degrees of freedom for this case is given by:
The Confidence level for this case is 0.95 or 95%, and the significance level 
and 
and the critical value is given by 
Replcing into the formula for the confidence interval is given by:
For this case the confidence interval is given by :
(2^8 *3^-5* 6^0)^-2 * ((3^-2)/(2^3))^4 * 2^28
anything to the 0 power is 1
(2^8 *3^-5* 1)^-2 * ((3^-2)/(2^3))^4 * 2^28
using the power of power property to take the power inside
(2^(8*-2) *3^(-5* -2) * (3^-2*4)/(2^3*4) * 2^28
simplify
2^ -16 * 3^10 * 3^-8 /2*12 * 2^28
get rid of the division by making the exponent negative
2^-16 * 3^10 * 3^-8 *2*-12 * 2^28
combine exponents with like bases
2^(-16-12+28) * 3^(10-8)
2^(0) *3^2
anything to the 0 power is 1
1*9
9
it is 40$$$Answer:
Step-by-step explanation:
Answer to 12: C.
Explanation: By dividing 60 by 15 you get 4 and by dividing 32 by 8 you get 4. 15 and 8 both go into it evenly so that is the answer.
Answer to 14: B
Explanation: when you divide 236.25 by 7 you get 33.75 and then multiply that by 2 and you get 67.7 so you know 2 fluid ounces of milk contain 67.7 mg of calcium
sorry i couldnt answer 13
Answer:
from one language to another
Step-by-step explanation: or in math In Euclidean geometry, a translation is a geometric transformation that moves every point of a figure or a space by the same distance in a given direction. In Euclidean geometry a transformation is a one-to-one correspondence between two sets of points or a mapping from one plane to another.
