a letter is chosen at random from the word 'mathematics'. Fin the probability that letter T is not chosen.

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:

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

a.)the line for function b is steeper
