A. 8.005 • 10² = 800.5 (Incorrect)
B. 8.500 • 10⁻³ = 0.0085 (Incorrect)
C. 8.005 • 10⁻⁴ = 0.000801 (Incorrect)
D. 8.005 • 10⁻³ = 0.008005 (Correct)
Answer: D. 8.005 • 10⁻³
You can solve a system with variables by:
1. Pick any two pairs of equations from the system.
2. Eliminate the same variable from each pair using the Addition/Subtraction method
3. Solve the system of the two new equations using the Addition/Subtraction method
4. Substitute the solution back into one of the original equations and solve for the third variable
5. check by plugging the solution into one of the other three equations
For the equation of the line expressed as Ax + By + C = 0, the value of the slope (m) is calculated by -A / B. For perpendicular lines, the slope of one should be the negative reciprocal of the other. From the choices given, the lines that are perpendicular is Option A.
Answer:
No.
Step-by-step explanation:
The central Limit Theorem states that the sample size must be greater than 30 for an approximate normal distribution.
