Answer:
6
(4×n²) + (4×n¹) + (5×n^0) = 173
4n² + 4n + 5 = 173
4n² + 4n = 168
divide through by 4
n² + n - 42 = 0
n² + 7n - 6n - 42= 0
(n + 7)(n - 6) = 0
n = -7 or 6
but the solution is 6 since base is not negative.
Answer:
A. Miguel has the greatest spread.
B. Considering the middle 50% of the training time, the person with the least spread is Adam.
C. Miguel is inconsistent with the time set for training compared to that of Adam.
Step-by-step explanation:
The spread of a data shows the range of the data.
Using the range to determine the spread of the given data:
A. The range of the two persons can be determined by:
Range = highest value - lowest value
So that:
Adam's range = 106 - 91
= 15
Miguel's range = 105 - 86
= 19
Comparing the range of the two, Miguel has the greatest spread.
B. Considering the middle 50% of the training time;
Adam - 103 105 104 106 100
Miguel - 88 86 89 93 105
Adam's 50% range = 106 - 100
= 6
Miguel's 50% range = 105 - 86
= 19
Considering the middle 50% of the training time, the person with the least spread is Adam.
C. The answers to parts 2(a) and 2(b) shows that; there is a wide variation (much inconsistency) in the time that Miguel spend during training, but a minimum variation in the time spent by Adam during training.

Answer:
5
Step-by-step explanation:
The area of a rectangle is given by base x height = 1 x 5 = 5
Solution:
Given:
The value of a car after t - years will depreciate.
Hence, the equation given represents the value after depreciation over t-years.
To get the rate, we compare the equation with the depreciation formula.
Hence,
Therefore, the value of this car is decreasing at a rate of 6%. The purchase price of the car was $16,300.
