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:
B. 467
A yellow ball will be selected about 467 times.
Answer:
The amount earned is $27,137.65
Interest earned is $17,137.65
Step-by-step explanation:
Here, we want to use the compound interest formula
We have this as follows;
A = P(1 + r/n)^nt
A is the amount
P is the principal which is the amount deposited = $10,000
r is the interest rate = 4% = 4/100 = 0.04
n is the number of times the interest is compounded per year;
Since it is every month, the number of times in a year is 12
t is the number of years = 25
Substituting these values;
A = 10,000(1 + 0.04/12)^(25*12)
A = $27,137.65
The interest earned is the difference between this amount and the amount deposited which is;
27,137.65 - 10,000 = $17,137.65
