Suppose that 80% of trees in a forest of 300 trees are infected with a virus, and we take an SRS (sample random sample) of 5 trees to test for the virus. What is the probability that exactly 2 of the 5 trees have the virus? P(X=2)=

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

c

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
