The mean of a binomial probability distribution is given by μ = np where n is the number of trials (number of samples) and p is the probability of success.

Given that a<span> statistics class at wilmington college has 25 students of which 15 are math majors and 10 are business majors and selecting a business major is defined as a success.

p = 10 / 25 = 0.4

If the professor randomly selects five students to work together on a group project, the mean of this probability distribution is given by 5 x 0.4 = 2.</span>

HELP ME!! SOMEBODY PLEASE HELP ME
IRISSAK [1]
6^2 = x (x - 9)
x^2 - 9x - 36 = 0
(x -12)(x + 3) = 0
x - 12 = 0; x = 12
x +3 = 0; x = -3

so in this case x = 12 then DC = 12 - 9 = 3

y^2 = 12^2 - 6^2
y^2 = 144 - 36
y^2 = 108
y = 10.4

What is the perimeter of the triangle
KengaRu [80]

The perimeter of the triangle is 40 units

<h3>Perimeter of a triangle</h3>

From the question, we are to determine the perimeter of the given triangle

From the given diagram, we can observe that the triangle is a right triangle

The vertical length of the triangle is 15 units

and the horizontal length of the triangle is 8 units

Thus,

We can find the hypotenuse by using the<em> Pythagorean theorem </em>

Let the hypotenuse be h

Then,

h² = 15² + 8²

h² = 225 + 64

h² = 289

h = √289

h = 17 units

Now, for the perimeter of the triangle

The perimeter of a triangle is the sum of all its three sides

Thus,

The perimeter. P, of the triangle is

P = 15 + 8 + 17

P = 40 units

Hence, the perimeter of the triangle is 40 units
