The value of x of the cubic equation e³ˣ + eˣ - 6 = 0 will be 0.49
<h3>What is a cubic equation?</h3>
The cubic equation is given as ax³ + bx² + cx + d = 0. Then degree of the equation will be 3. Then we have
The cubic equation will be
e³ˣ + eˣ - 6 = 0
Let eˣ = u, then the equation will be
u³ + u - 6 = 0
Then the root of the equation is calculated by the calculator, then we have
u = 1.634, -0.817, -0.817
eˣ = 1.634, -0.817, -0.817
Take log on both sides, then we have
x = ln 1.634, ln(-0.817), ln(-0.817)
x = 0.49, not defined, not defined
Then the value of x will be 0.49.

Answer:
If you asked a lot of students from this particular university how many classes they are registered for, the average of classes will be 4.15.
Step-by-step explanation:
The expected value is the average of the discrete random variable in the long run. If an event occurs many, many times the average value of the outcomes gets closer to the expected value, and when the sample is big you get the expected value.
