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

Step-by-step explanation:
14 - 8 + 3 + 8 × [24 ÷ 8}
14 - 8 + 3 + 8 × [3}
14-8+3+24= 33
= 33
Answer:
a. (2x - 3)(x - 4)
b. 17 m, 6 m
c. 46 m
Step-by-step explanation:
a.
2x² - 11x + 12 = (2x - 3)(x - 4)
b.
2x - 3 = 2(10) - 3 = 17
x - 4 = 10 - 4 = 6
c.
P = 2L + 2W = 2(17) + 2(6) = 46
30 times .4=12
30-12=18
The sales price would be $18
Answer:
We have: 2x+7y=−1
Let’s express this equation in terms of y:
⇒y=−27x−17
⇒ Gradient =−27
Parallel lines always have the same gradient:
⇒ Gradient of parallel lines =−27
Perpendicular lines have the negative reciprocal of the gradient:
⇒ Gradient of perpendicular lines =72
