We know that 5 days and 12 hours is as much as 5.5 days, so all we need to do is to multiply 1800 watt-hours by 5.5 days:

1800 * 5.5 = 9900

Answer: <u>A light bulb consumes 9900 watt-hours each 5 days and 12 hours</u>.

The completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

<h3>What is polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is a real number).

The polynomial equation given in the problem is,

p^4 - 16

Let the factor form of the polynomial is f(p). Thus,

f(p)=p^4 - 16\\f(p)=p^4 - 2^4\\f(p)=(p^2)^2- (2^2)^2

Using the formula of difference of squares, we get,

f(p)=(p^2-4)(p^2+4)\\f(p)=(p^2-2^2)(p^2+4)\\f(p)=(p-2)(p+2)(p^2+4)

Thus, the completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

What is the mean absolute deviation of the following set of data 10 4 12 4 2 10 10 6
mart [117]

The mean absolute deviation of the given data 10, 4, 12, 4, 2, 10, 10, 6 is 3.1875.

According to the given question.

The given data set is

10, 4, 12, 4, 2, 10, 10, 6

Mean of the given data set  

= (10 + 4 +  12 + 4 + 2 + 10 + 10 + 6)/8

= 7.25

Now, the absolute values are:

|10 - 7.25| = 2.75

|4 - 7.25| = 3.25

|12 -7.25| = 4.25

| 4 - 7.25| = 3.25

| 2 - 7.25| = 5.25

| 10 - 7.25| = 2.75

| 10 - 7.25| = 2.75

| 6 - 7.25| = 1.25

The average of all absolute values

= (2.75 + 3.25 + 4.25 + 3.25 + 5.25 + 2.75 + 2.75 + 1.25)/8

= 25.5/8

= 3.1875

Therefore, the mean absolute deviation of the given data 10, 4, 12, 4, 2, 10, 10, 6 is 3.1875.
