i bought a box of chips worth $12.98, there are 30 bags of chips in the box. How much is 1 bag of chips worth ? please help

Answer:

10.94

Step-by-step explanation:

The standard deviation is calculated by using the following formula:

$s=\sqrt{\frac{1}{N-1}sum(xi -x)^2}$

This means that N is the total number of cases you want to take into account, times the sum of x at the ith position - x squared.

In other words, the standard deviation in your example implies the following:

26 is the first value, so i = 1, 34 is the second value, so i = 2, 18 where i = 3, and so on and so forth, until you reach the end, which is 6 (so the initial value is 1 and the last one is 6).

You're doing a sum over an iteration of all the numbers in your sample.

So applying the sum of all of the numbers, it gives us the following:

$(26-28)^2+(34 - 28)^2+(18 - 28)^2 ... (41 - 28)^2$

$= \frac{598}{5} \\=119.6\\$

The sum of all of the numbers in your sample is equal to 119.6.

Substitute into the equation once again:

$s=\sqrt{119.6}$

Where the square root of 119.6 is 10.93617...

Rounded to two decimal places: 10.94

How should this model be completed to represent 642/11 ??<br><br> Enter the answer in the box.

Rashid [163]

Model be completed to represent 642/11 is 29.1818181818

$\frac{642}{11}$ = 58.3636363636

58.3636363636 = 583.636363636 to the nearest tenth

58.3636363636 = 58.36 to the nearest hundredth

58.3636363636 = 58.364 to the nearest thousandth

= 0 to the nearest tenth

= 0 to the nearest hundredth

= 0 to the nearest thousandth

642 divide by half plus 20

( $\frac{642}{2}$ ) + 20 = 341

642 divide by half plus 40

( $\frac{642}{2}$ ) + 40 = 361

$\frac{642}{11}$ divided by 2

( $\frac{642}{11}$ ) ÷ 2 = 29.1818181818

Division is one among the four basic operations of arithmetic, the ways in which numbers are combined to make new numbers. the opposite operations are addition, subtraction, and multiplication.

At an elementary level the division of two natural numbers is, among other possible interpretations, the method of calculating the number of times one number is contained within another.7 This number of times needn't be an integer. for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).

The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which is that the number of times the second number is completely contained in the first number, and a remainder, which is that the part of the first number that remains, when within the course of computing the quotient, no further full chunk of the dimensions of the second number can be allocated. for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.

For division to always yield one number instead of a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.
