You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.
For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers
-9+-5+-4+-3+-1=-22
-22/5=-4.4
the mean for those set of numbers is -4.4

x=2 then,
3*2^2 - 2*2+1
3*4-4+1
12-4+1
9
Step-by-step explanation:
Simplify:
3x^2 - 2x + 1
=> 3(2)^2 - 2(2) + 1 [∵ x = 2 (Given)]
=> 3(4) - 2(2) + 1
=> 12 - 4 + 1
=> 13 - 4
=> 9 Ans.

Answer:
Step-by-step explanation:
10*10=100
including jasmine with her 9 friends we have 10 people giving away 10 samples of chocolate each. Every person has to give away 10 samples. So 10 times 10. Which gives us a 100. I hope i understood your question correctly.
your answer: 100 samples given out in total

5/6x -4 =6
how do you solve for x?
Answer:
x=12
Step-by-step explanation:
so first you add 4 to both sides:
[tex]\frac{5}{6}[/tex]x - 4 = 6
+4 +4
= [tex]\frac{5}{6}[/tex]x = 10
now you divide 10 by [tex]\frac{5}{6}[/tex] or you can flip the fraction upside down and multiply it by 10:
[tex]\frac{6}{5}[/tex] × 10 = [tex]\frac{60}{5}[/tex] = 12
x = 12
Solve for x:
Add 4 to both sides-
5/6x - 4 = 6
+4 +4
5/6x = 10
Now divide 5/6 on both sides-
(5/6)/(5/6) = 10/(5/6)
x = 12
hope this helps !!

Answer:
20
Step-by-step explanation:
coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y).
Write an equation for a line in slope-intercept form that is perpendicular to the line y = 4x + 3 and passes through the point (-4, -2).
Answer: The equation of the line perpendicular to y = 4x + 3 and passes through the point (-4, -2) is y = -(1/4)x - 3.
Step-by-step explanation: An line perpendicular to perpendicular to the line y = 4x + 3 would have a slope that is the negative inverse of the refernce line. That would make the new line's slope -(1/4), the negative inverse of 4,
We can write the new new as y = -(1/4)x + b. b, the y-intercept, is +3 in the original equation, but it will change for the new line. We can calculate the new y-intercept by using the one point, (-4,-2) that we know is a solution for the equation (it falls on the line).
y = -(1/4)x + b
-2 = -(1/4)(-4) + b
-2 = 1+b
b = -3
The equation of the line perpendicular to y = 4x + 3 and passes through the point (-4, -2) is y = -(1/4)x - 3.

Answer:
a. [tex]4^2[/tex]
b. 16
Step-by-step explanation:
The area of a square is equal to the side length squared. Normally, the area of a rectangle is length times width but since all sides are equal in a square it is just the side times the side. This can be simplified to side length squared.
Since the side length is 4 the exponent form of the area is simply 4 squared or [tex]4^2[/tex].
Then, compute this by multiplying 4*4. This equals 16 cms square.

Properties used:
All angles of a triangle add up to 180 degrees
180 is a straight line; so both sides of a straight line add up to 180
10) 180 - 153 = 27
180-27-133 = ?
? = 20 degrees
11) 180-87=93
180-93-23=?
? = 64 degrees
Answer:
11.) Angle FED = 20 Degrees | 12.) Angle FHG=74
Step-by-step explanation:
11.) Angle FED= 20 degrees
one side of a straight line = 180 degrees
all the angles of the insides of a triangle added together = 180 degrees
If angle EDF is 153 degrees, we do 180 - 153 = 27 degrees. Now we know that angle FDE = 27 degrees. Now we add all the angles we have together. 133+?+27=180. (133+27=160) If 160+?=180, we solve it by doing: 180-160, and we get 20.
12.) Angle FHG=74
For this problem, we use the same formulas as before. So let's solve!
180-87=93. So angle GFH=83 degrees.
Now we need to add the angles together:
83+23+?=180. 83+23=106
180-106=74.

Answer:
look below
Step-by-step explanation:
going left and right changes the x( first number in each parentheses)
going up and down changes the y (second number in parentheses)
going to the left by 9 means all the first numbers are going in the negative direction (-9)
going up by 12 means the second numbers are going in the positive direction (+12)
take all x values and add -9, take all y values and add 12
X (-15, 13)
Y(-5,12)
Z(-8, 15)
The distance a train travels between 2 cities is 540 miles. The train travels at a speed of 80 miles per hour. Matt set up these rates to find the time it took the train to travel between the 2 cities.
80 miles
1 hour
= ? hours
540 miles
What was Matt’s error?
The first rate should be written as 80 hours to 1 mile.
The second rate should be written as a rate of distance to time.
The first rate should compare miles to miles.
Matt did not make an error.
