The wall street journal reported that the age at first startup for 30% of entrepreneurs was 29 years of age or less and the age at first startup for 70% of entrepreneurs was 30 years of age or more. (a) suppose a sample of 200 entrepreneurs will be taken to learn about the most important qualities of entrepreneurs. show the sampling distribution of p where p is the sample proportion of entrepreneurs whose first startup was at 29 years of age or less. if required, round your answers to four decimal places.

i need more information to answer

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

what "following statement"?

step-by-step explanation:

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.
