Answer:
41.92%
Step-by-step explanation:
In table attached standard normal distribution curve is shown.
Data
mean, µ = 4.3 minutes
standard deviation, σ = 0.5 minutes
desired point, x = 5 minutes
x-axis, Z = (x - µ)/σ
The probability that calls last between 4.3 and 5.0 minutes is equivalent to find the area below the curve between Z = 0 and Z = (5 - 4.3)/0.5 = 1.4, which is 0.4192, or 41.92%
Answer:
[-3,9]
Step-by-step explanation:
you look at the x axis
Answer:
43
Step-by-step explanation:
x=2, y=3 is a pair of a equations right there, so a correct solution.
How about another linear system?
Answer: x+y=5, 10x + y = 23
