Answer with explanation:
The average rate of change in a function f(x) from x=a to x=b is given by :-
For Section A .
The average rate of change in a function h(x)=4x from x=0 to x=1 is given by :-
For section B .
The average rate of change in a function h(x)=4x from x=2 to x=3 is given by :-
The average rate of section A is same for section B because the function is a linear function, and the rate of change of a linear function is constant.
Answer:
0.9945 = 99.45% probability that the student answers at most four questions correctly
Step-by-step explanation:
For each question, there are only two possible outcomes. Either the student answers correctly, or he/she does not. The probability of the student answering a question correctly is independent of any other question. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
A quiz consists of six multiple choice questions.
This means that
Each question has four choices. Student guesses randomly.
This means that
What is the probability that the student answers at most four questions correctly?
This is:
In which
. So
0.9945 = 99.45% probability that the student answers at most four questions correctly
