Answer:
x-coordinate: 2
y-coordinate: 3
Step-by-step explanation:
X always comes first in ordered pairs
0.000000001 is 10^-9 in scientific notation ( as there are 9 digits after the decimal point)
Answer is 2.5 * 10^-9
Answer:
15.85%
Step-by-step explanation:
Empirical rule states that for a normal distribution, 68% of the data falls within one standard deviation, 95% falls within two standard deviation and 99.7% falls within three standard deviation.
Given mean (μ) = 41 months, standard deviation (σ) = 5 months
One standard deviation = μ ± σ = 41 ± 5 = (36, 46)
Therefore 68% falls within 36 months and 41 months
Two standard deviation = μ ± 2σ = 41 ± 2(5) = (31,51)
Therefore 95% falls within 31 months and 51 months
Three standard deviation = μ ± 3σ = 41 ± 3(5) = (26, 56)
Therefore 99.7% falls within 26 months and 56 months
The percentage of cars that remain in service between 46 and 51 months = 32%/2 - 0.3%/2 = 16% - 0.15% = 15.85%
Answer:
discriminant = 0
Step-by-step explanation:
discriminant is b² - 4ac
in this problem, a = 1, b = -10, c = 25
you plug the values of a, b, and c into the discriminant formula: b² - 4ac
(-10)² - 4(1)(25) = 100 - 100 which equals zero
