a fair coin is tossed until either a tail occurs or 5 heads in a row have occurred. let x denote the number of tosses. find the frequency function, mean and variance of x.

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.

hi there!

the answer is: 2 and -2

step-by-step explanation:

case 1: an absolute value of positive number will still be a positive number

so absolute value of 2 is 2

case 2: an absolute value of negative number will be positive number so absolute value of -2 is 2

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
