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?

Our math team had m students last year, but this year it has already n students! By what percent did the number of students grow
AlekseyPX
For this case we are going to assume the following:
 m: whole number greater than zero.
 n: integer greater than zero.
 Where,
 n> m
 According to these assumptions, the percentage of growth is given by the following formula:
 (n / m) * 100 - 100
 Answer:
 
the number of students did grow by:
 
(n / m) * 100 - 100

Which represents the solution(s) of the system of equations, y = x^2 - 6x + 8 and y = -x + 4? Determine the solution set by grap
Len [333]

Answer:

(1, 3) and (4,0)

Step-by-step explanation:

The quadratic function is y=x^2-6x+8

We can rewrite in the form y=(x-3)^2-1

The graph is obtained by shifting the parent quadratic function 3 units right and 1 unit down to obtain the parabola shown in the attachment.

The straight line also have equation y=-x+4

The slope is -1 and y-intercept is 4.

We can easily graph this straight line on the same graph as shown in the attachment.

The two graphs intersected at (4,0) and (1,3).

The solution set is therefore  {(x,y)|x=4,y=0 or x=1,y=3}
