Mrs. avery is going to randomly select one student from her class to read a poem out loud. there are 151515 boys and 131313 girl
2 answers:
P(boy) is asking for the probability that a boy will be chosen to read a poem out loud. Since there are 15 boys, we can get the probability by dividing this with the total number of students. This is because out of all the students, there is an equal possibility that each of the 15 boys will be chosen.
ANSWER: The probability that a boy is selected is 0.5357 or 53.57%

First divide both sides by 2:
Move the constant term to the right side:
Since
we want to have
Then
So in our equation, we need to add 49/16 to both sides in order to complete the square:
Answer:
Domain of the given function is all real numbers and the range of the function all real numbers.
Step-by-step explanation:
The given function is
.... (1)
The slope intercept form of a line function is
.... (2)
Where, m is slope and b is y-intercept.
From (1) and (2), we get
It means the slope of the line is -5 and y-intercept is 4.
Draw a line with slope -5 and y-intercept 4 on a coordinate plane as show below.
Domain is the set of inputs and range is the set of outputs.
The function is defined for all values of x. So, the domain of the function is all real numbers.
The value of function can be any real number. So, the range of the function is all real numbers.
Therefore, the domain of the given function is all real numbers and the range of the function all real numbers.
