Answer:
(0, 127.85714285714)
Step-by-step explanation:
To find the y-intercept of the line, you need to find the equation of the line first.
The format of an equation of a line is: y = mx + c where m is the slope and c is the y-intercept (which is what we want to find).
Slope = 
= 
= 
Slope = 
Thus, the slope of a line is -
.
To find the y-intercept, we just have to put in the slope of the line in an ordered pair.
y = mx + c
-117 = -(-36) + c
-117 = 10
+ c
c = -117 - 10
c = -127
Thus, the y-intercept of a line is (0, -127 ).
PS: Since it's a fraction, I'm not too sure how you would want to present it. Below are the different forms of the same answer. Depending on your question, you can choose the most appropriate form to take.
The mixed number form is: -127
The improper fraction form is: -
The decimal form is: -127.85714285714
Answer:
Forty-seven percent is the statistic and 31% is the parameter
Step-by-step explanation:
Various terms are used in mathematics when it comes to carrying out particular studies in statistics.
A) Parameter
A parameter when is comes to statistical studies can be defined as the term that tells us more about a group or population of people.
B) Statistic
Statistic is a measure that tells us about is a characteristic of a sample or part of a given population.
In the above question, we are told that: a study of parents of kindergarteners included 349 parents who were chosen at random. Of these parents, 47% said they sent their children to pre-kindergarten. School records show that only 31% of parents of kindergarteners sent their children to pre- kindergarten.
According to the definition of Parameter and Statistic that I explained above,
A) The Parameter is 31% . This is
because it tell us about percentage ( a sample) of parents whose children are in kindergarten that sent their children to prekindergarten first.
B) The Statistic is 47% . This is because, it tell us about the percentage of parents that sent their children to prekindergarten.
CLASS A
Mean: 4.8
Median: 5
Range: 6
CLASS B
Mean: 4
Median: 4
Range: 5
Therefore, the mean study time of students in Class B is less than that of students in Class A.
