Congruent means they are the same size
To prove the two triangles are congruent you would need to know the length of at least two of the sides. If two sides were not known you would need to know the length of one side and at least one of the unknown angles.
Answer:
a

d
Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158 is greater than 3( Note :the probability of z-score = 3 is 97%)
e
The correct option is option 3
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.25
The sample size is n = 508
Generally the mean is mathematically represented as

=> 
=> 
Generally the standard deviation is mathematically represented as

=>
=>
Generally the z-score of 158 is mathematically represented as

=> 
=> 
Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158 is greater than 3( Note :the probability of z-score = 3 is 97%)
What this means is that the almost the whole professional hockey league player are born in the first month which is unusual
These are two questions and two answers.
Question 1. The ordered pair given in the first row in the table can be written using function notation as?
Answer: f(-2) = 1
Justification:
In functions, the notation f(x) denotes the image (ouput) obtained when you apply the rule (function) to the value x, i.e. x is the input.
So, for example, the image of x = 5 is f(5), the image of x = 2,000 is f(2,000), the imaga of x = - 100.5 is f(-100.5).
In the table, the first row shows that the image of x = -2 is 1, so f(-2) = 1, and that is the answer to the question.
Question 2. f(x) = –2 when x is?
Answer: x = 4.
Justification.
You are requested to find which value of x makes the function f(x) equals -2.
Therefore, you have to see that in the third row of the table it is shown that f(x) is - 2 when x = 4., and that is the answer.
All the following expressions mean the same and are used when you deal with functions:
- the ordered pair (4, -2),
- the image of 4 is - 2
- the preimage of -2 is 4
- f(4) = -2
- f(x) = -2, when x = 4.
