Answer:

quantities or total number of observations

Step-by-step explanation:

Average also known as mean is a measure of central tendency. It is determined by adding the numbers together and dividing it by the total number

Average = sum of the numbers / total number

For example, there are 3 numbers 3 , 6, 9

Average = ( 3 + 6 + 9) / 3 = 18 / 3 = 6

Kyra has a rock collection. When she puts her rocks into 2 equal plies, there are no rocks left over. When she puts her rocks in

Nat2105 [25]

Step-by-step explanation:

According to this description we need a number that can be divided by 2,3 and 4 since the amount of rocks can be described by a natural number. However if a number is divided by 4 it is divided by 2 as well since 2*2=4.

$\frac{x}{4} = \alpha \\ \frac{x}{2} = 2 \alpha$

If α is a natural number then 2*α is a natural number as well as the product of two natural numbers.

Which means that we need a number devided by 3 and 4.

The smallest number that fulfills this demand is 3*4=12.

Also any product of 12 with any natural number can be devided by 3, 4 and 2.

If the exercise asks for the numbers that are divided only by 2,3 and 4 these are:

${3}^{ \alpha } \times 12 \: and \: {4}^{ \alpha } \times 12 \: \\ where \: \alpha \: belongs \: to \: the \: set \: of \: all \: \\ natural \: numbers$

A box of oat cereal costs $3.90 for 15 ounces.A box of rice cereal costs $3.30 for 11 ounces.Which box of cereal costs less per

allsm [11]

To solve this is you have to find the price per ounce for each item by simply dividing the price by the ounces.

For the oat cereal divide $3.90 by 15

3.90/15

.26 per ounce

For the rice cereal divide $3.30 by 11

3.30/11

.30 per ounce

The oat cereal costs less per ounce since it is only .26 per ounce whereas the rice cereal is .30 per ounce.

Hope this helps!
