Answer:

Step-by-step explanation:

y = C(x - 1/3)(x - 1/3)(x + 1/4)

y = C(x² - 2/3x + 1/9)(x + 1/4)

y = C(x³ - 2/3x² + 1/4x² + 1/9x - 1/6x + 1/36)

y = C(x³ - 5/12x² - 1/18x + 1/36)

now to account for the y intercept (x = 0)

-3 = C((0)³ - 5/12(0)² - 1/18(0) + 1/36)

-3 = C(1/36)

C = -108

distribute the C term across all variables.

y = -108x³ + 45x² + 6x - 3

we can verify our solution using a plotting calculator.

Nitella [24]

Answer:

Option A is correct.

A uniform distribution.

Step-by-step explanation:

Complete Question

T-Mobile sells 6 different models of cell phones and have found that they sell an equal number of each model. The probability distribution that would describe this random variable is called:

A) Uniform Distribution

B) Continuous Distribution

C) Poisson Distribution

D) Relative Frequency Distribution

Solution

A uniform distribution is one in which all the variables have the same probability of occurring.

It is also known as a rectangular distribution, as every portion of the sample space has an equal chance of occurring, with equal length on the probability curve, leading to a rectangular probability curve.

And for this question, 6 different models of phones sell an equal number, hence, the probability of selling each model is equal to one another, hence, this is evidently a uniform distribution.

Hope this Helps!!!
