Answer:
Median without outlier should be 40
For the bottom questions, it should go:
Decreases the mean, does not change the median, does not change the mode
It's decreasing the mean because it goes from 44.7 to 39
Median w/ and without outlier is both 40
Mode also stays the same w/ or without the outlier, which is 96

Answer:
Let's work this out.
n - 3 / n + 3
n / n + 6
In order to avoid it cancelling out, we only cancelled out one side.
2n = 6
n = 3

Can you plz help me because it says that it’s wrong?
Answer:
202
Step-by-step explanation:
So it has to end in 2 because 20t+22 will always be a 2.
day1:
17x1+49=66
no 2
day2:
17x2+49=83
odd
day3:
D=100
no 2
day4:
odd
day5:
D=134
no 2
etc
keep adding 17 to D until you get one that ends in 2
D=202
A=202
The line segment between (9,6) and (-2,-1) is bisected at (3.5,2.5). Find the y-intercept of the perpendicular bisector.
Ans: y-intercept = (0, _____)
Answer:
Y-intercept is (0,8)
Step-by-step explanation:
Firstly, we need to get the equation of the line segment
We have the general equation as;
y = mx + b
m is the slope and b is the y-intercept
So for the slope between (9,6) and (-2,-1); we have
m = (y2-y1)/(x2-x1)
m = (-1-6)/(-2-9) = -7/-11 = 7/11
Mathematically, when two lines are perpendicular, their slopes have a product of -1
Let the slope of the second line be m
m * 7/11 = -1
7m = -11
m = -11/7
The equation of the second line is;
y = mx + b
y = -11x/7 + b
The line passes through the point (3.5,2.5)
So,
2.5 = -11/7(3.5) + b
2.5 = -5.5 + b
b = 2.5 + 5.5
b = 8
so the y-intercept of the perpendicular bisector is 8

4x4+4x3-9x2-x+2 = x-1
Answer:
x= 13/2
Step-by-step explanation:
multiply 4x4+4x3-9x2-x+2=x-1
calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13
solution x=13/2

Answer:
The third number line where x = -2, 2
Step-by-step explanation:
The solution is, the number line represents the solutions is given below.
here, we have,
given equation is,
25x + 200 > 1,200
Subtract 200 from each side
25x + 200-200 > 1,200-200
25x> 1000
Divide by 25
25x/25 >1000/25
x>40

PLEASE HELP ME ITS MY LAST QUESTION!!
Write three very large numbers and three very small numbers. Now write them using scientific notation. Then
perform one calculation with the numbers.
100 = 10^2
1000 = 10^3
10000 = 10^4
0.1 = 10^(-1)
0.01 = 10^(-2)
0.001 = 10^(-3)
Now,
100 × 0.1 = 10^2 × 10^(-1)
= 10

(13x + 12x) divided by 4 = 10
What is x
Answer: x is 8/5
Step-by-step explanation:
Answer:
x = [tex]\frac{8}{5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{13x+12x}{4}[/tex] = 10 ( multiply both sides by 4 to clear the fraction )
25x = 40 ( divide both sides by 25 )
x = [tex]\frac{40}{25}[/tex] = [tex]\frac{8}{5}[/tex]
3x + 2y = -2
2x - 2y = -18

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?
Answer:
I mean I don't know your options, but the answer is probably something like y=180x
Step-by-step explanation:
Answer:
1440
Step-by-step explanation:
Sum= (180)(8)=1440
Better:
Sum= (x-2)(180)
x represents the number of sides
So it would be
sum=(10-2)(180)
The answer then would be 1440
It is given that yvaries directly as x. If y= 5 when x= 4 determine the constant of variation,
Answer:
[tex]k=\dfrac{5}{4}[/tex]
Step-by-step explanation:
Given that,
y varies directly as x. It means,
y = kx
Where
k is the constant of variation
or
[tex]k=\dfrac{y}{x}\\\\k=\dfrac{5}{4}[/tex]
So, the constant of variation is [tex]\dfrac{5}{4}[/tex].
