Human blood can contain the A antigen, the B antigen, both the A and B antigens, or neither antigen. It may or
may not also contain the Rh antigen. Blood is called type
A-positive if the individual has the A and Rh but not the B
antigen. A person having only the A and B antigens is said
to have type AB-negative blood. A person having only the
Rh antigen has type O-positive blood. Other blood types
are defined in a similar manner. In a certain hospital, the
data, shown to the right, was recorded. Use a Venn
diagram to answer parts (a) through (h) about the blood
samples. For parts (d) through (h), the presence or
absence of antigens determines blood type.

answer: idk

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
