gulaghasi [49]

Answer:

<u>The approximate total weight of the grapefruits, using the clustering estimation technique is B. 35 ounces.</u>

Step-by-step explanation:

We notice that the weights of the grapefruits given are slightly down or above 7, then we will use <em>7 as our cluster</em> for the estimation, as follows:

Weights

7.47 ⇒ 7

7.23  ⇒ 7

6.46  ⇒ 7

7.48  ⇒ 7

6.81  ⇒ 7

<u>Now we can add up 7 + 7 + 7 + 7 + 7 for the weights of the grapefruits and the approximate total weight is B. 35 ounces.</u>
