Let n = 2.5. what is the value of 2n(6n-3)+4n?

Answers

Answer 1

Answer: $n = 2.5, \ \n\n\ 2n(6n-3)+4n = 12n^2 - 6n +4n =12n^2-2n\n \n12n^2-2n=12 *(2.5)^2-2*2.5=12*6.25-5=75-5=70$

Answer 2

Answer: $2n(6n-3)+4n$

substitute $n=2.5$

$2*2.5(6*2.5-3)+4*2.5=5(15-3)+10=60+10=70$

I can see your problem immediately . . . there's no question !

Since y^2 + 6y + 9 can be factored, the polynomial is not factored all the way. To factor it, try (y + 3)(y+3) or simply put, (y +3)^2. Don't forget to keep the 6y^2, so the completely factored version would be : 6y^2 (y+3)(y+3)

Answer:

Step-by-step explanation:

To calculate the Mean Absolute Deviation (MAD) for a set of data, follow these steps:

1. Find the mean (average) of the data set by adding up all the values and dividing by the total number of values. In this case, the sum of the values is:

85 + 91 + 93 + 99 + 99 + 99 + 102 + 108 + 110 + 115 = 1001

Dividing 1001 by 10 (the number of values) gives us the mean:

1001 / 10 = 100.1

2. Subtract the mean from each value in the data set and take the absolute value of the result. This gives us the deviation of each value from the mean. For example, the deviation of the first value (85) from the mean (100.1) is:

|85 - 100.1| = 15.1

Repeat this step for all the values in the data set.

3. Calculate the average of these deviations to find the Mean Absolute Deviation. Add up all the deviations and divide by the total number of values. In this case, the sum of the deviations is:

15.1 + 8.9 + 6.9 + 0.9 + 0.9 + 0.9 + 1.9 + 7.9 + 9.9 + 14.9 = 77.1

Dividing 77.1 by 10 (the number of values) gives us the Mean Absolute Deviation:

77.1 / 10 = 7.71

Therefore, the correct answer is not listed among the given options. The MAD for the given data set is approximately 7.71 (in thousands of dollars) or $7,710.
