6. Suppose the class takes a test and the following averages are obtained: mean = 80, median= 90, and mode = 70. Tom, who scored 80, would like to know if he did better than half the class. What is your response?
We know that the mean is 80, the median is 90, and the mode is 70. This means that the majority of students got an 80 on the test.
However, the median is 90, which means half of the class is below 90 where Tom's grade is placed.
Hence, he did not do better than half of the class.Point DD is located at (-6,-5)(−6,−5) on the coordinate plane. Point DD is reflected over the xx-axis to create point D'D ′ . What ordered pair describes the location of D'?D ′ ?
The ordered pair that describes the location of N is (2,6)
Given:
N's coordinates are: (-2,-6)
Point N ′ is produced by reflecting point N over the y-axis.
By reflecting point N' over the x-axis, the final point N" is produced.
x , y = -x , y
N(-2 -6) = N'(2 6)
To locate the ordered pair describing where N" is located.
Point N's coordinates are (-2,-6). Point N ′ is produced by reflecting point N over the y-axis.
x , y = -x , y
N(-2 -6) = N'(2 6)

Put the following equation of a line into slope-intercept form, simplifying all fractions.
4x-20y=-160
The equation of the line 4x-20y = -160 in the slope intercept form is y = x/5 + 8 .
The equation of the line in slope intercept form is written as
y = mx + c ,
where m is the slope of the line , and c is the y intercept .
In the question ,
the equation of the line is given
equation of line is given as 4x-20y = -160
to convert the equation in slope intercept form , we rewrite it as
20y = 4x+160
dividing both sides by 20 ,
we get
20y/20 = 4x/20 + 160/20
y = x/5 + 8
hence ,the slope intercept form is y = x/5 + 8 , where 8 is the y intercept and 1/5 is the slope .
Therefore , the equation of the line 4x-20y = -160 in the slope intercept form is y = x/5 + 8 .

The elephants at the zoo eat 3 1/6 buckets of bananas each day. The zookeeper bought 6 1/3 buckets of bananas. How many days will the bananas last?
Write your answer as a fraction or as a whole or mixed number.
The bananas will last 2 days at the zoo (found by division).
According to the question,
We have the following information:
The elephants at the zoo eat [tex]3\frac{1}{6}[/tex] buckets of bananas each day. The zookeeper bought [tex]6\frac{1}{3}[/tex] buckets of bananas.
Now, first we will find the number of days taken in eating 1 bucket of bananas.
[tex]3\frac{1}{6}[/tex] buckets = 1 day
Now, we will convert this mixed fraction into simple fraction.
19/6 buckets = 1 day
1 bucket = 1/(19/6) days
1 bucket = 6/19 days
Now, we have the total number of buckets as [tex]6\frac{1}{3}[/tex].
Now, after converting this mixed fraction, we have:
19/3 buckets
1 bucket = 6/19 days
19/3 buckets = (6/19)*(19/3)
19/3 buckets = 2 days
2 is a whole number.
Hence, the given buckets of bananas will last 2 days.

The equation of the line that passes through the point (8, 0) is parallel to the line x - 4y = 20 is 1/4x - y = 2
Given,
The equation of the line: x - 4y = 20
The points which the line passes through, (x₁, y₁) = (8, 0)
We have to find the equation of the line parallel to the given line.
The formula for the slope intercept form:
(y - y₁) = m(x - x₁)
m is the slope of the line.
Lets find the slope of the line given.
x - 4y = 20
x = 20 + 4y
x - 20 = 4y
y = (x - 20) / 4
y = 1/4x - 5
Here, slope of the line is 1/4
Now, substitute the slope of the line and (x₁, y₁) in the slope intercept formula to get the equation of line parallel to the given line
(y - y₁) = m(x - x₁)
(y - 0) = 1/4(x - 8)
y = 1/4x - 8/4
y = 1/4x - 2

The difference between three times a number and 4
Answer:
3x - 4
Step-by-step explanation:
"Difference" is a clue word that tells you to use subtraction. The other clue word is "times" but that means times, or multiplication and is pretty straight forward.
"Three times a number" means to multiply a number, but we don't know the number, so we use a variable (a letter). I put x but you could use n or c or almost any letter for the variable.
"the difference of ___ and ___" means to subtract those two things.
So we get 3x - 4
