xeze [42]

Answer:

  4

Step-by-step explanation:

The perimeter of each square window is 4 times the length of one side, so is 20 feet.

80 feet can be divided into 80/20 = 4 sections of 20 feet each.

Shelly has enough lights to surround 4 windows.

Two different numbers are selected simultaneously and at random from the set {1,2,3,4,5,6,7,8,9,10}. What is the probability tha
ehidna [41]

The probability of getting positive difference between the numbers 3 or greater between 1,2,3,4,5,6,7,8,9,10 if two numbers are selected is 28/45.

Given Numbers:{ 1,2,3,4,5,6,7,8,9,10}

We have to find the probability that the positive difference between the numbers selected is 3 or greater.

Probability is the likelihood of happening an event among all the events possible.

Total number of combinations when two numbers are selected from 10 numbers is 10 C 2=10!/2!(10-2)!

=10*9*8!/2*1(8!)

=10*9/2

=45 combinations

Combinations of numbers whose difference will be 3 or more are: (10,7),(10,6),(10,5),(10,4)(10,3)(10,2)(10,1)(9,6)(9,5)(9,4)(9,3)(9,2)(9,1)(8,5)(8,4)(8,3)(8,2)(8,1)(7,4)(7,3)(7,2)(7,1)(6,3)(6,2)(6,1)(5,2)(5,1)(4,1)

Total numbers =28

Probability=numbers/total combinations

=28/45

Hence the probability that two numbers selected gives difference of 3 or more is 28/45.

A) Graph the function and label all zeros. Be sure to label the axis and what you are incrementing by.
Liono4ka [1.6K]

9514 1404 393

Answer:

  • graph is shown below
  • absolute max and min do not exist
  • local max: 0 at x=0
  • local min: -500/27 ≈ -18.519 at x=10/3

Step-by-step explanation:

The function is odd degree so has no absolute maximum or minimum. It factors as ...

  g(x) = x^2(x -5)

so has zeros at x=0 (multiplicity 2, meaning this is a local maximum*) and x=5.

Differentiating, we find the derivative of g(x) is zero at x = 0 and x = 10/3.

  g'(x) = 3x^2 -10x = x(3x -10)   ⇒   x=0 and x=10/3 are critical points

The value of g(10/3) is a local minimum. That value is ...

  g(10/3) = (10/3)^2((10-15)/3) = -500/27 ≈ -18.519

__

The local maximum is (0, 0); the local minimum is (10/3, -500/27). The graph is shown below.

_____

* When a root has even multiplicity, the graph does not cross the x-axis. That means the root corresponds to a local extremum. Since this is the left-most root of an odd-degree function with a positive leading coefficient, it is a local <em>maximum</em>. (The function is <em>increasing</em> left of the left-most turning point.)

The formula for the area of a triangle is A=12bh. Solve this equation for b.
aksik [14]

Step-by-step explanation:

Hey there!

Given;

[A = 1/2b*h]

Divide both sides by 'h'.

A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].

Multiply '2' and 'A'.

A*2/h = b

b = 2A/h.
