The heights of 200 adults were recorded and divided into two categories.

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

Response:

Part a) The price of raisins is $0.8 for each ounce

Part b) 1.25 ounces

Detailed explanation:

The accurate question is

Jackson purchased 5 ounces of raisins costing him $4 dollars.

a) What is the cost per ounce of raisins?

b) How many ounces of raisins could one get for $1?

Part a)  What is the cost per ounce of raisins?

It is established that

To calculate the unit price, divide the total expense by the total weight

thus

consequently

The raisins are priced at $0.8 for each ounce

Part b) How many ounces of raisins can be obtained with $1?

It is known that

The raisins are sold at $0.8 per ounce

by using proportions

Determine how many ounces of raisins one can purchase for $1

Let

x -----> the ounces of raisins
