Jerry took a sample of 4 employees in his office and observed how many hours they each worked one day.
Illusion [34]

The error in Jerry's calculation is 4.84

The number of employees, N = 4

The mean is calculated as:

\mu = \frac{10+2+4+8}{4} \\\mu = \frac{24}{4} \\\mu = 6

The formula for the standard deviation is:

SD =\sqrt{\frac{\sum{(x-\mu)^2}}{N} }

This can be further calculated as:

SD = \sqrt{\frac{(10-6)^2+(2-6)^2+(4-6)^2+(8-6)^2}{4} }\\\\SD = \sqrt{\frac{4^2+(-4)^2+(-2)^2+(2)^2}{4} } \\\\SD = \sqrt{\frac{16+16+4+4}{4} } \\\\SD = \sqrt{\frac{40}{4} } \\\\SD = \sqrt{10} \\\\SD = 3.16

Jerry thinks the Standard Deviation = 8

The true Standard Deviation = 3.16

Error = |True value - Measured value|

Error = |3.16 - 8|

Error = 4.84

Perform the indicated operation. Show all necessary work.
densk [106]

The subtraction of a negative number is the same as addition of the

positive equivalent of the number.

The outputs of the operations are;

  • (a) -2 - (-9) = 7
  • (b) -2 - 9 = -11
  • (c) -2 + 9 + 2 = 9

Reasons:

(a) The operation is -2 - (-9)

Which is the subtraction of negative 9 from negative 2, which gives, a double negative, which is equivalent to a positive, therefore, we get;

-2 - (-9) = -2 + 9 = <u>7</u>

<u />

(b) The operation is -2 - 9

The above operation is the subtraction of +9 from negative 2, which gives;

-2 - 9 =<u> -11</u>

(c) The operation is -2 - (-9) - (-2)

The above operation is the subtraction of negative 9, and negative 2 from

negative 2, and therefore, has two double negatives that result two

positive(s) increases, as follows;

-2 - (-9) - (-2) = -2 + 9 + 2 = 9

What is the benefit of having a quadratic on vertex form?
kobusy [5.1K]
<span> The advantages of those forms are right in their name.
If you are trying to find the vertex of an equation, all you have to do is write down (h,k)
Standard form is good for using the quadratic formula, since it has a,b, and c
Factored form is good when trying to factor out an equation, eg (ax^2 + bx + c) and is used for writing down polynomials.
