In a board game, players take turns spinning a wheel with 4 spaces and values of $100, $200, $400, $900. The probability of landing on $100 is .22. The probability of landing on $900 is .54. The probability of landing on $400 is .23. The probability of landing on $200 is 0.01 What is the expected value of spinning the wheel once? Show work

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:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
