The time that a butterfly lives after emerging from its chrysalis can be modelled by a random variable T, the model here taking

the probability that a butterfly survives for more than t days as P(T>t)=36(6+t)2, t≥0. For these problems, please ensure your answers are accurate to within 3 decimals. Part a) What is the probability that a butterfly will die within 6 days of emerging? 0.75 Part b) If a large number of butterflies emerge on the same day, after how many days would you expect only 6 % to be alive? 18.494 Part c) Calculate the mean lifetime of a butterfly after emerging from its chrysalis?

Written as a simplified polynomial in standard form, what is the result when
Naddika [18.5K]

Step-by-step explanation:

7x+10 - (x+2)^2

7x+10 - (x^2 + 2x + 4)

7x+ 10 - x^2 - 2x - 4

5x + 6 - x^2

then if u have to find the value of x then put the value of a = 1,b = 5,c = 6 in quadratic formula (-b + under root b^2 - 4ac / 2a) or (- b - under root b^2 - 4ac / 2a) it will gives the value of x...

HOPE it u..!!

edit - do let me knw that it's right or not..!!
