Answer:
3.24%
Step-by-step explanation:
Percentage error =[ (|calculated value - actual value) / actual value] x 100
calculated area = length x width
6.5 x 7.8 = 50.7
[(|50.7 - 52.4|] / 52.4] x 100 = 3,24
Answer:
Mean and standard deviation of the sample mean are 225.8 and 3.56 respectively.
Step-by-step explanation:
The mean (μₓ) and standard deviation of the sample mean (σₓ) are related to the mean (μ) and standard deviation of the population (σ) through the following relationship
μₓ = μ = 225.8
σₓ = σ/√n = 17.8/√25 = 17.8/5 = 3.56
Answer:
x = 9 or x = 0
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 4 x - 5 x = 0
x^2 - 4 x - 5 x = x^2 - 9 x:
x^2 - 9 x = 0
Factor x from the left hand side:
x (x - 9) = 0
Split into two equations:
x - 9 = 0 or x = 0
Add 9 to both sides:
Answer: x = 9 or x = 0
