Sergei runs a bakery. He needs at least 175175175 kilograms of flour in total to complete the holiday orders he's received. He only has 343434 kilograms of flour, so he needs to buy more. The flour he likes comes in bags that each contain 232323 kilograms of flour. He wants to buy the smallest number of bags as possible and get the amount of flour he needs.
Let FFF represent the number of bags of flour that Sergei buys.

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:

school a:

minimum value is 2

maximum value is 22

the lower quartile is 2.5

the median is 10

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12

the median is 16

the upper quartile is 18

box plot for school a isn't symmetrical. the data tails on the right

box plot for school b isn't symmetrical. the data tails on the left
