Answer:
3
Step-by-step explanation:
Add up the exponents of the variables
5xyz = 1+1+1 = 3
The degree is 3
Answer:
The answer is below
Step-by-step explanation:
From the table, the mean (μ) = 1390.75 and the standard deviation (σ) = 518.75
The confidence level (C) = 90% = 0.9
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1 / 2 = 0.05
The z score of α/2 (0.05) is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.645.
The margin of error (E) is given as:

The confidence interval = μ ± E = 1390.75 ± 228.07 = (1162.68, 1618.82)
The confidence interval is between 1162.68 and 1618.82.
Answer: 271 miles
Step-by-step explanation:725÷8 to find the MPH which is 90.625. Then
multiply 90.625 by 3 which is 271.
