Answer:
c. x = 1/a
Step-by-step explanation:
4ax + 5ax = 3ax + 6
9ax = 3ax + 6 (addition property of equality)
6ax = 6 (subtraction property of equality)
6ax/6 = 6/6 (division property of equality)
ax/a = 1/a (simplify)
x = 1/a
The probability the man will win will be 13.23%. And the probability of winning if he wins by getting at least four heads in five flips will be 36.01%.
<h3>How to find that a given condition can be modeled by binomial distribution?</h3>
Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
P(X = x) = ⁿCₓ pˣ (1 - p)⁽ⁿ⁻ˣ⁾
A man wins in a gambling game if he gets two heads in five flips of a biased coin. the probability of getting a head with the coin is 0.7.
Then we have
p = 0.7
n = 5
Then the probability the man will win will be
P(X = 2) = ⁵C₂ (0.7)² (1 - 0.7)⁽⁵⁻²⁾
P(X = 2) = 10 x 0.49 x 0.027
P(X = 2) = 0.1323
P(X = 2) = 13.23%
Then the probability of winning if he wins by getting at least four heads in five flips will be
P(X = 4) = ⁵C₄ (0.7)⁴ (1 - 0.7)⁽⁵⁻⁴⁾
P(X = 4) = 5 x 0.2401 x 0.3
P(X = 4) = 0.3601
P(X = 4) = 36.01%

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.
