neurons are cells in the nervous system that process and transmit info. An average neuron is about 5 x 10^-6 meter in diameter. A standard table tennis ball is 0.04 meter in diameter. About how many times as great is the diameter of a ball

Ratio = Diameter of ball/Diameter of neuron

Ratio = 0.04 m/5×10⁻⁶ m

Ratio = 8,000

Therefore, the tennis ball is 8,000 times larger than the neuron,

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
