Radius of a wheel = 13 inch
= 1.08333 ft
circumference of a wheel = 2×pi×r^2
= 2 × (22/7) × 1.08333^2 ft
= 2 × (22/7) × 1.1736 ft
= (44/7)×1.1736 ft
= 51.6384/7 ft
= 7.3769142857 ft
distance covered in one minute = 37 × 60 ft/min
= 2220 ft/min
now, revolution per minute = 2220 / 7.3769142857
= 300.93884
therefore her wheels are making 300.93884 revolutions per minute
Answer:
Mean is the measure of central tendency is most appropriate to describe the given data.
Step-by-step explanation:
We are given the following in the question:
The distribution of time in seconds is a bell shaped distribution that is a normal distribution.
Properties of a normal distribution:
- The mean, mode and median for a normal distribution are equal.
- The mean divides the data into two equal parts.
- The area under the graph is 1.
- Thus, mean is the most appropriate measure of central tendency for normally distributed data.
Thus, the correct answer is
Mean is the measure of central tendency is most appropriate to describe the given data.
Answer:
See attached diagram
Step-by-step explanation:
See attached picture....I assumed -3% was really just -3
I don't know part 1 but
Part B: It's increased 6cm at segment P, decreased 6cm at segment R, stays constant for 1 second at segment Q
Part C: First the Ant takes 3 seconds climbing up 6cm of the hill then stays there for 1 second then takes 3 seconds climbing 6cm back down the hill.
(79 + 94 + 91 + 92 + x) / 5 > = 90
(356 + x) / 5 > = 90
356 + x > = 90 * 5
356 + x > = 450
x > = 450 - 356
x > = 94 <=== Sherman can get the lowest score at 94
