Assume that you have a large sample of radioactive atoms, arranged in a rectangular lattice. Imagine that this lattice has some

number of rows and columns, with an atom in each lattice-position.
Now, in this scenario, the atoms do *NOT* decay independently. Instead, each row and column of atoms decays independently. More specifically, imagine that each row of atoms decays as a random variable, independently of all other rows and columns. Say that the probability of any particular row decaying over the course of one hour is 10%. In addition, each column of atoms decays as a random variable, independently of all other rows and columns
Say that the probability of any particular column decaying over the course of one hour is 40%.
Can you make a model for how the total number of atoms decays?
Make a graph/plot of your model, illustrating the amount of radioactive material you expect as a function of time in hours).
Does the total number of atoms decay exponentially?
If so, can you define a decay rate for the total number of atoms?

At a local school dance, the booster club is having a fundraiser selling pictures. Pictures without frames sell for $5, and with
Sergeu [11.5K]
Let p = pictures only
let f = pictures with frames

p + f = 100
5p + 10f = 875

Solve for one variable in the first equation then plug into the second

p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75

75 pictures with frames were sold

MAVERICK [17]

Answer:

6

Step-by-step explanation:

x^{2} - 6x +5 = 0

x^{2} - 6x + 9 -9 +5 = 0

[x^{2} - 6x + 9] - 4 =0

(x -3)^{2} -4 = 0

(x -3)^{2} = 4

(x-3) = \sqrt{4} or (x-3) = - \sqrt{4}

(x-3) = 2 or (x-3) = -2

x = 5 or x = 1

therefore, sum of these solutions is 5+1 = 6

Find the value of x in the picture please
Marianna [84]

Answer:

Option B. The value of x is 20

Step-by-step explanation:

we know that

<u>The intersecting chords theorem</u>  states that the products of the lengths of the line segments on each chord are equal.

so

In this problem

(x)(x-11)=(x-8)(x-5)\\x^{2}-11x=x^{2}-5x-8x+40\\-11x=-13x+40\\2x=40\\x=20
