Answer:
YES, the number of people who visited the park can be represented as a function of the daily average temperature.
Step-by-step explanation:
From the table of values given which defines the number of visitors to the park as a function of daily temperature, the temperature is the domain values (independent variable), while the number of visitors is the range values (dependent variable).
For any relation to be considered a function, as a principle, any given domain value must have exactly one range value. In other words, there must not be two different range values assign to one domain value.
This means, for the relation between temperature and number of visitors to be considered a function, it must not have a domain value that is mapped to more than one range value.
Examining the table given, if we map each domain value to the range value, we will find out that there are only 1 exact range value for a domain value.
<em>Therefore, we can say: YES, the number of people who visited the park can be represented as a function of the daily average temperature.</em>
Answer:
a) 1470 ways
b) 2835 ways
Step-by-step explanation:
the question is not correct, in the correct question The number of independents should be 3 not 2
there are 7 republicans, 10 democrats and 3 independents.
C(n,r) is the number of different combinations of n distinct objects taken r at a time.
C(n,r) = 
a) it will consist of 1 Republican and 4 Democrats
The number of ways this can be chosen is = C(7,1) × C(10,4) =
= 7 × 210 = 1470 ways
(b) it will consist of 2 Republicans, 2 Democrats, and 2 Independents (consist of 2 independents not 3)
The number of ways this can be chosen is = C(7,2) × C(10,2) × C(2,2)
=
= 21 × 45 × 3 = 2835 ways
