Five pulse rates are randomly selected from a set of measurements. the five pulse rates have a mean of 71.0 beats per minute. four of the pulse rates are 53, 79, 75, and 57. a. find the missing value. b. suppose that you need to create a list of n values that have a specific known mean. some of the n values can be freely selected. how many of the n values can be freely assigned before the remaining values are determined?

b) phosphorus pentoxide

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
