Answer: what’s the questions to number 5 and 4
Step-by-step explanation:
The conclusion is P(pass l morning) = 0.56
P(pass l afternoon) = 0.72
Conclusion: a student taking the test in the afternoon has a greater probability of passing than a student taking the test in the morning.
<h3>What are the probabilities?</h3>
Probability is the odds that a random event would happen. The odds that the event would happen lies between 0 and 1. The closer the probability is to one, the more likely it is for the event to happen.
P(pass l morning) = number of students who took the test in the morning and passed / total number of students that took the exam in the morning
28 / 50 = 0.56
P(pass l afternoon) = number of students who took the test in the afternoon and passed / total number of students that took the exam in the afternoon = 36 / 50 = 0.72

<span>We simplify the equation to the form, which is simple to understand
<span>q+2/5=2q-11/7
Simplifying:
<span>q + 0.4=2q-11/7
Simplifying:
<span>q + 0.4=2q-1.57142857143
We move all terms containing q to the left and all other terms to the right.
<span>+1q-2q=-1.57142857143-0.4
We simplify left and right side of the equation.
<span>-1q=-1.97142857143
We divide both sides of the equation by -1 to get q.
<span>q=1.97142857143</span></span></span></span></span></span></span>
