Answer:
1) The value of c is given by
2) The value of k is given by
Step-by-step explanation:
Given that function g is defined by , where c is a constant.
To find c:
Also given that value of g(x) at x=0.5 is equal to -1
ie.,
At x=0.5
Therefore
2) Given that function h is defined by , where k is a constant.
To find k:
Also given that value of h(x) at x=20 is equal to 65
ie.,
At x=20
Therefore
Option C: np is the expression used for calculating the mean of a binomial distribution.
Explanation:
From the options, we need to determine the expression that is used for calculating the mean of a binomial distribution.
<u>Option A: npq</u>
The variance of the binomial distribution can be calculated using the expression npq.
Hence, Option A is not the correct answer.
<u>Option B: </u><u></u>
The standard deviation of the binomial distribution can be calculated using the expression
Hence, Option B is not the correct answer.
<u>Option C: np</u>
The mean of the binomial distribution can be calculated using the expression np
Hence, Option C is the correct answer.
<u>Option D</u>:
The mean of the binomial distribution cannot be determined using the expression
Hence, Option D is not the correct answer.
