Based on the absolute deviations and the predicted values, the sum of absolute deviations will be <u>4.8.</u>
<h3>What would be the sum of absolute deviations from predicted values?</h3>
This can be found as:
= ∑ (Observed value - Predicted value)
The observed values are given in the table and the predicted values will be calculated using y = 3.6x - 0.4.
Solving gives:
= [3 - (3.6 x 1 - 0.4)] + [7 - (3.6 x 2 - 0.4)] + [ 9 - (3.6 x 3 - 0.4)] + [14 - (3.6 x 4 - 0.4)] + [15 - (3.6 x 5 - 0.4)] + [21 - (3.6 x 6 - 0.4)] + [25 - (3.6 x 7 - 0.4)]
= 0.2 + 0.2 + 1.4 + 0 + 2.6 + 0.2 + 0.2
= 4.8

Answer:
8
Step-by-step explanation:
The constant of proportionality bus the amount earned by Ronnie, E, all over the corresponding hours he used in working, h.
Constant of proportionality = 
From the graph given, when h = 5, E = 40.
Therefore:
Constant of proportionality = 
I Think the answer is x+2y=16 please I’m sorry if the answer is wronge
Rates are used to compare related quantities such as costs of items in two countries
<h3>How to determine the ratio</h3>
The question is incomplete;
So, I will give a general explanation on how to calculate the rate.
Assume that the costs are:
United Kingdom = 500
Canada = 750
The ratio would be:
Ratio = United Kingdom : Canada
So, we have:
Ratio = 500 : 750
Simplify
Ratio = 2 : 3
Express as rate
Rate = 2/3
Using the assumed values, the rate of the total cost for items in the United Kingdom to that of the total cost of items in Canada is 2/3

to find the volume u need to multiply the l*w*h <br />formula: V= LxWxH <br />calculate de length width and height and multiply each that is going to give u the volume and u will have your answer ☺
