Answer:
0.21
Step-by-step explanation:
Given that Jane is a better tennis player than Jack is. If the probability that Jane will beat Jack in any given game is 0.7,
Probability for Jane beating Jack is 0.7 and hence
Probability for Jack beating Jane is 0.3
We find that each game is independent of the other
If two games are played
Probability that they will each win one game if they play two games
= Prob that Jack wins one game * Prob that Jane wins one game
= 0.7*0.3
= 0.21
(Since if A and B are independent events P(AB) = P(A) *P(B)

Solution:
we are given that
The state of New Jersey has a population of about 8.9 million and its area is about 8700 mi².
we have been asked to find the population density of New Jersey?
As we know the population density is defined as the population per square unit of area.
Population=8.9 million=8900000
Area=8700 mi².
Hence population density can be given as
The population density of New Jersey 1023.
Answer:
Domain- -4,-2,0,2 Range- -3,0,2,3,5
Step-by-step explanation:
(x,y)
The domain is the x
The range is the y
And if the number is there more than once you only have to list it once.
Typically you list them from least to greatest so the smallest number the higher number.
Answer:
Candace must make 32 sales.
Step-by-step explanation:
You can describe Candice weekly pay as a first degree function.
In our function, each sale n is the independent variable and her pay P is the the dependent variable. P is dependent of n, so we are going to write as P(n).
So, we can model the equation of P as a function of n by the following equation:
P(n) = 425 + 17.75n,
where, as the problem states, 425 is the flat rate and 17.75 is her comission for each sale n.
Now, the question is how many sales must Candace make to make $993 in one week. So, we want P(n) to be equals to $993 and we have to find n.
993 = 425 + 17.75n
Now we just need to solve this equation
993-425 = 17.75n
568 = 17.75n
n = 568/17.75
n = 32
So, to make $993 in one week, Candace must make 32 sales.
