A project is graded on a scale of 1 to 5. If the random variable, X, is the project grade, what is the mean of the probability distribution below? A probability distribution is shown. The probability of 1 is 0. 1; 2 is 0. 2; 3 is 0. 4; 4 is 0. 2; 5 is 0. 1. 0. 2 0. 4 1 2003.

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

my guess is

step-by-step explanation:

(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
