For a binomial process, the probability of success is 40 percent and the number of trials is 5. Find the variance.
Natalka [10]

Answer:

1.2

Step-by-step explanation:

The variance of a binomial distribution is:

σ² = n p (1 − p)

where n is the number of trials and p is the probability of success.

Given n = 5 and p = 0.40:

σ² = 5 (0.40) (1 − 0.40)

σ² = 1.2

Find the vertex of the given function.
IRISSAK [1]

<em>The </em><em>vertex of the function is at (5, 10)</em>

<em>For the function, th</em><em>e domain exists </em><em>on all </em><em>real numbers</em><em> while the range exist for the value</em><em> f(x) ≥ 10</em>

<h3>Vertex, domain and range of a function</h3>

The vertex of a quadratic or linear function is in the form

y =  a(x – h)^2 + k

where;

(h, k) is the vertex of the function

Given the function expressed as;

f(x) = |x-5| + 10

On comparison, you can see that h = 5 and k =10, hence the vertex of the function is at (5, 10)

<u>For the domain and range</u>

Domain are the dependent variable for which a function exist while the range is the independent variable for which a function exist.

For the function, the domain exists on all real numbers while the range exist for the value f(x) ≥ 10

Witch is not a function {(7,8),(−4,4),(3,8),(−7,−1)} \{(-5, -3), (-1, -8), (-7, 0), (-5, -9)\}{(−5,−3),(−1,−8),(−7,0),(−5,−9)} \
iris [78.8K]

Given:

The relations are:

{(7,8),(−4,4),(3,8),(−7,−1)}

{(-5, -3), (-1, -8), (-7, 0), (-5, -9)}

{(8,4),(6,−1),(−4,5),(9,4)}

{(8,−3),(4,0),(−4,9),(3,2)}

To find:

The relation that is not a function.

Solution:

A relation is a function if there exist unique y-value for each x-value and a relation is not a function if there exist more than one y-values for any x-value.

In option B, the given relation is:

{(-5, -3), (-1, -8), (-7, 0), (-5, -9)}

Here, y=-3 and y=-9 for x=-5. There exist more than one y-values for x=-5. So, this relation is not a function.

In other three relations, all x-values are different, so there exist unique y-value for each x-value. It means the relations in options A, C and D are functions.

Therefore, the correct option is B.
