Dead trees In Rocky Mountain National Park, many mature pine trees along Highway 34 are dying due to infes- tation by pine beetles. Scientists would like to use a sample of size 200 to estimate the proportion of the approximately 5000 pine trees along the highway that have been infested. (a) Explain why it wouldn't be practical for scientists to obtain an SRS in this setting.
(b) A possible alternative would be to use the first 200 pine trees along the highway as you enter the park. Why isn't this a good idea?
(c) Describe how to select a systematic random sample of 200 pine trees along Highway 34,

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
