Mr. Whitman gave a test to his 32 math students. He felt the results were low, so he retested them one week later. The results of the original and retake test are shown below.
A. What is the difference in the median grade?
B. Compare the percent of students who got at least a 60 on the original test to those that got at least a 60 on the retake.
C. If the students need a 65 in order to pass the test, how many more passed the retake?
The number of student more passed the retake, when the students need a 65 in order to pass the test is 8.
What is box and whiskers plot?Box plot is the way of representation of data which gives the graphical image of the data set to understand better. In this the data is represented with the help of quartile.
A.The difference in the median grade-The median of first test is 60 while the second test is 80. Thus, the difference is,
[tex]d=80-60\\d=20[/tex]
B. Compare the percent of students who got at least a 60 on the original test to those that got at least a 60 on the retake.The student, who got at least 60 in first test, falls in the second half of the plot. Thus, the 50% of students got atleast 60% marks. In the retake test, all 100% student got at least 60 on test.
C. If the students need a 65 in order to pass the test, how many more passed the retake?In the first test 1/4 are passed while in second test 3/4 students are passed and got the marks 65 or more than this, Thus the number of student pass more in this test,
[tex]n=(\dfrac{3}{4}-\dfrac{1}{2})\times 32\\n=8[/tex]
Thus, the number of student more passed the retake, when the students need a 65 in order to pass the test is 8.

Answer:
rounded to the nearest whole number = 166
Step-by-step explanation:
Add all of the angles together, to get 39x. In a hexagon, all the angles add up to 720. Divide 720 by 39 to get x, then multiply x by 9, as that is the largest angle to get an answer rounded to the nearest whole number of 166.

Given f(x) =4x + 8 and g(x) = x^2 + x ; find ( f o g ) ( -5 )
Answer:
88
Step-by-step explanation:
(fog)(-g) = f(g(-5))
g(-5) is 20
f(20) is 88
The composition of the function at x = -5,
(fog)(-5) = 88.
What is composite function?Let the two function f(x) and g(x) generate a new function h(x) using an operation.
The operation is composition of functions and h(x) is a composite function.
Given:
Two functions,
f(x) =4x + 8,
and g(x) = x² + x.
g(-5) = 20
The composition of the function at x = -5,
(fog)(-5) = f(g(-5))
(fog)(-5) = f(20)
(fog)(-5) = 20(4) + 8
(fog)(-5) = 88
Therefore, (fog)(-5) = 88

a) Write an equation in terms of x that represents the problem. (b) Solve the problem.
The difference of 4 and a number is − 9. Find the number.
Part 1 of 2
The equation that represents the problem is_______ ?.
The number is_____?
Answer:
the equation is
x - 4 = - 9
the number is
-5
Step-by-step explanation:
First, we don't know the number so we represent it with a variable like "x".
then difference simply means subtraction.
" is" simply means = ( equal to)
so the question says that difference of 4 and a number is 9 so we have x - 4 = -9
so now let's solve for x
we group liked terms and make x stand alone.
x = -9 + 4
( +4 because it crossed an equal sign)
x = - 5
we have
x = -5
so we can substitute the -5 into the equation to if its true
from the equation x - 4 = - 9
where we put -5 instead of x
-5 - 4 = - 9
Identify which value will be used for a variable. Write an equation that represents the problem Solve the problem
Question:

breaks. How many breaks were taken?
Using proportions, it is found that when the Axolotl was swimming, 8 breaks were taken.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, in each break there are 6 yards. How many breaks are there in 48 yards? Hence the rule of three is given by:
1 break - 6 yards.
n breaks - 48 yards.
Applying cross multiplication:
6n = 48.
n = 48/6.
n = 8.
8 breaks were taken.
