The mean value of land and buildings per acre from a sample of farms is ​$1500​, with a standard deviation of ​$100. The data set has a​ bell-shaped distribution. Assume the number of farms in the sample is 76. Use the empirical rule to estimate the number of farms whose land and building values per acre are between ​$1300 and ​$1700. farms?

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

step-by-step explanation: i dont

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.
