According to the probability histogram for a discrete random variable X, what is μx?

a. 3.15

b. 3.05

c. 2.89

d. 2.65

e. 0.2

40 minutes

step-by-step explanation:

add the time and multiply by 2

answer: about 22.67

step-by-step explanation:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

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:
