To win a loto in one state, one must correctly select 7 numbers from a collection of 48 numbers (1 through 48). the order in which the selection is made does not matter. how many different selections are possible?

Step-by-step explanation:

Since the order in which you select the numbers is not important then we have a combination problem

The formula of combinations is:

Where n is the number of objects you can choose, and you choose r from them

Then you will get the number of possible ways to select r objects from a group of n objects

In this case we have that:

Therefore:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
