Answer:
8.18 cubic inches
Step-by-step explanation:
An orange is a sphere so you will use the formula for the volume of a sphere.
V= 4
/3 * π * r^3 r^3= 1.25* 1.25 * 1.25= 1.953
V= 4/3* 3.14 * 1.953 = 8.176=8.18
Answer:
50 or more

Answer: in 95% of races, his finishing time will be between 62 and 64 seconds.
Step-by-step explanation:
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 63 seconds and the standard deviation is 5 seconds.
2 standard deviations = 2 × 0.5 = 1
63 - 1 = 62 seconds
63 + 1 = 64 seconds
Therefore, in 95% of races, his finishing time will be between 62 and 64 seconds.
