Load the data set all countries. write an r function called sample gdp() that will randomly sample of a user-defined number of these countries and calculate the median gross domestic product (in $us) per capita. use the r function sample gdp() to randomly sample 5, 10, 15, 100, 200, and all of these countries. comment on the findings. include the command set. seed(302) before the first function call and after the function definition for reproducibility. you only need to include the command once. do not include the command before each function call.

b

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

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:
