<u>According to given table we have pairs of points:</u>

  • (4, 6.00), (5, 8.25), (6, 10.50)

<u>The rate of change is:</u>

AP and BQ are medians of the triangle ABC and K is the centroid of the triangle.
One of the properties of  the medians is that the point of intersection divides the median in the ratio 2:1

Answer:

0.156

Step-by-step explanation:

Using binomial probability formula, we have :

P( a out of n ) =ⁿCₐ x pᵃ x qⁿ⁻ᵃ  ------------------------------------------------- (1)

Where n = total number of sample

           a = number of success

            p = probability of success

            q = probability of failure

            n-a = number of failures

From the question:

n =10 , a = 7, p=0.54, q = 1-p = 0.46

Substituting into equation (1) we have:

P (7 out of 10) =  ¹⁰C₇ x (0.54)⁷x (0.46)¹⁰⁻⁷

                      = 0.1563

                     ≈ 0.156
