Flip 10,000 fair coins*. The number of heads will be around 5000 , give or take about . (Enter the expected value of the number of heads, and its standard error.) *This experiment has been performed, and the expected value and standard error empirically verified, by John Kerrich in the 1940s.

mean, 40.6

step-by-step explanation:

69.64%

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
