Line graphs (or line charts) are best when you want to show how the value of something changes over time, or compare how several things change over time relative to each other. Whenever you hear that key phrase “over time,” that's your clue to consider using a line graph for your data.

Answer:
y = 2x - 1
Step-by-step explanation:
Consider the differences between consecutive values of y. If constant then this value is the multiplier.
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 9 - 7 = 2 ← constant difference, hence
y = 2x
Given the point (0, - 1 ) then we require to subtract - 1, that is
y = 2x - 1 ← equation relating x and y
Answer:
0.0367 = 3.67% probability that exactly 6 patients will die
Step-by-step explanation:
The patients are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:

In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this question, we have that:
20 patients means that 
Sample of 8 means that 
9 have the heart problem, so 
What is the probability that exactly 6 patients will die?
This is P(X = 6).


0.0367 = 3.67% probability that exactly 6 patients will die

<u>Answers: </u>
In the given identities a + 0 = 0 + a will represent the additive identity.
<u>Solution: </u>
The additive identity says that if you add a real number to zero or add zero to a real number, then you get the same real number back. This can be written as,
A + 0 = A
The number zero is known as identity element or the additive identity.
Let us understand the additive property using a example:
Let us consider the case 0 + 40 = 40, here 0 represents the identity value.
When we add zero to real number 40, we get the result as 40 which is the same number.
Hence, on the given options, the value a + 0 = a will represent the additive identity.
9 1/2 quarts is the same as 38 cups. So you would just subtract 38-7 to get 31. So 31 cups were drank.
