Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
Answer:
Extensive property
Step-by-step explanation:
The intensive properties does not depend on the amount of mass of the system or the size of the system, for example the density 
is a quantity that is already defined for the system, because the density of water is equal for a drop or for a pool of water.
In the case of extensive properties the value of them is proportional to the size or mass of the system. For example mass is an extensive property because depend on the amount of substance. Other example could be the enegy.
In the case of weigth is a quantity that depends on mass value, then weigth is an extensive property.
I think answer is A
Because slope=rise/run
Rise is 3
Run is 2
But it will be negative because of the direction of slope
Answer:
a=-b(x-1)
Step-by-step explanation:
Is it factored, but that question doesn't have too much helpful in it
