What is the mean of the values in the dot plot? enter your answer in the box. a number line ranging from 15 to 25 with one dot over 16, four dots over 17, four dots over 19, one dot over 21, two dots over 22, one dot over 23, and one dot over 25.

19.5

Step-by-step explanation: I took the test.

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:
