Consider the following game. Every time you play, it'll cost you $5.00. You have a 1 in 20 chance to win $30.00, a 1 in 5 chance to win $10.00, and a 15 in 20 chance to receive nothing.. What is expected value.?

Formula give is Probability(of winning) x $ (gain) - probability (of losing) x $loss

i need points

step-by-step explanation:

sorry bubs

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

so mark-up is 0.4 multiplied by 180 = 72
