The answer is B A = 0, B = 1 , C = 3
Answer:
A. The distribution should be skewed to the left because the mean is less than the median.
B. Most students scored a C or higher.
Step-by-step explanation:
A. Since mean<median<mode, we have a negative skewness and hence the distribution is skewed to the left.
B. Since the mean score is 71 and the modal score is 81, it is expected that a 'C' should be the lowest grade most students will have.
Step-by-step explanation:
Equating two statements is called proportion. By property of the proportion, the cross product of the mean is equal to cross product of the extreme. Also we can denote as ratio of extreme and mean.
A×B=B×C
Answer:
Aidan got <u>56%</u> of votes.
Step-by-step explanation:
Given:
Aidan is running for student body president. In today's election, he received 462 votes out of a total of 825 votes cast.
Now, to find the percent of votes did Aidan get.
<em>Total votes cast = 825 votes.</em>
<em>Votes he received = 462 votes.</em>
Now, to get the percent of votes Aidan get:




Therefore, Aidan got 56% of votes.
Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
Step-by-step explanation:
We are given a function
and we need to find domain and range of this function
Domain:
The domain of a function is the set of points for which the function is real and defined.
Since all the values give the result which is real and defined so domain is all real numbers.
Range:
The set of values of the variable that is dependent, the function should be defined.
So, all the values should be greater than 0 i.e {y | y > 0}
So, Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
