Answer:
Required output = 14
Step-by-step explanation:
Sum of the input 3 and 4 = 3 + 4
Twice the sum means two times.
So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.
2(3 + 4)
Perform the addition inside the parentheses.
2(3 + 4) = 2(7)
Now, multiply.
2(3 + 4) = 14
Hence, required output = 14

What can be used to predict diameter, given family income
We can see (by observation) that the data on the table can only be represented on a scattered plot, and scattered plot uses regression equation for data prediction.
i.e.
--- equation of line of best fit
In this case;


<em>When the x value (income) is known, we can simply plug in the value in the above equation to get the y value (diameter)</em>
