A minimum sample size of 75 is necessary. Step-by-step explanation: We need to determine our level, which is calculated by subtracting 1 from the confidence interval divided by 2. Now, we need to find the z value in the Z table that corresponds to a p-value of [Z value]. Therefore, it is the z value with a p-value of [specific value]. Next, we calculate the margin of error M, where [insert equation], with [standard deviation] representing the population standard deviation and n as the sample size. The standard deviation equals the square root of the variance. With a 0.95 probability level, if the margin of error desired is 5 or below, a sample size of at least 75 is required.

Answer:

The term 6x should actually be 6x²

Step-by-step-explanation:

The illustration referenced, which depicts the multiplication of the trinomial with the binomial, is provided in the image below.

To identify where Chin's multiplication went wrong and to establish the correct expression, we'll analyze each multiplication performed. Therefore, we have:

3x*x² = 3x³

3x*2x = 6x² (the mistake occurred here, as Chin recorded it as 6x in the chart)

3x*4 = 12x

2*x²=2x²

2*2x = 4x

2*4 = 8

Thus, the term 6x should indeed be corrected to 6x²
