The weight load on an airplane pallet is normally distributed with a mean of 250 pounds and a standard deviation of 40 pounds. What is the probability that a randomly selected pallet will support more than 290 pounds

0.1587

Step-by-step explanation:

Given : The weight load on an airplane pallet is normally distributed with a mean of 250 pounds and a standard deviation of 40 pounds.

i.e. pounds

pounds

Let x be the weight load on an airplane pallet.

Then, the probability that a randomly selected pallet will support more than 290 pounds will be :-

Hence, the required probability is 0.1587 .

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.
