It is expected that the proportion of tuna caught using a particular technique is 0.8. What is the probability that in a random sample of 84 fishing trips, the proportion of tuna caught is greater than 0.8? Round to four
decimal places.

is only a line? i think so

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

what? that isnt a question

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
