What is the mean of the set of data below?
Answer:
Mean = 8
Step-by-step explanation:
add all the numbers
2+3+5+6+8+11+11+12+14 = 72
then divide by how many number there are which is 9
72 / 9 = 8

10.
plug in x to check work
Step-by-step explanation:
8.
1/2(x + 24) = 21
1/2x +12 = 21
1/2x = 9
x = 18
9.
28 - 3x - 4 = 2x + 12 + x
24 - 3x = 3x + 12
24 - 6x = 12
-6x = -12
x = 2
10.
3x - 18 + 6 = 5x - 6
3x - 12 = 5x - 6
-2x - 12 = -6
-2x = 6
x = -3
hope it help.

Find the midpoint of BF B(0,-14) F(4,6)
Answer:
Step-by-step explanation:
B(0, -14) ⇒ x₁ = 0 & y₁ = -14
F(4,6) ⇒ x₂ = 4 & y₂ = 6
[tex]Midpoint = \left(\dfrac{x_{1}+x_{2}}{2}, \dfrac{y_{1}+y_{2}}{2} \right)[/tex]
[tex]=\left(\dfrac{0+4}{2},\dfrac{-14 + 6}{2}\right)\\\\\\= \left(\dfrac{4}{2}, \dfrac{-8}{2} \right)\\\\\\=\left(2, -4 \right)[/tex]

Please answer question in screen shot
Answer:
1 (the answer will always be 1)
Step-by-step explanation:
Let's forget about the absolute value signs for a second and just look at what's inside
[tex]\frac{x+y}{-x-y}[/tex]
This can be rewritten as
[tex]-\frac{x+y}{x+y}[/tex]
When you have the same numerator and denominator, it will always come out to 1, so we can just say that this is saying
[tex]-\frac{x+y}{x+y} = -1[/tex]
Now, back to the absolute value signs
This comes out to negative 1, but the absolute value signs means to always change the negative to a positive (but if it's a positive, it stays positive!)
So that means:
[tex]|-1| = 1[/tex]
and 1 is your answer

A home builder needs to cover the rectangular floor of a closet with a carpet the closet is 2 yards long and 2/3 of a yard wide how much carpet will the home builder need to cover the closet?
Your Answer is 4 Yards
Step-by-step explanation:
2/3 yards is 2 feet
2 yards is 6 feet
2 times 6 feet is 12 foot e.g. (2 x 6 = 12)
12 feet is 4 yards.
Formula (L x W = A)
L = length
W = Width
A = Area

A company wants to decrease their
energy use by 15%. If their electric
bill is currently $2,100 a month,
what will their bill be if they are
successful? Give your answer
accurate to at least the nearest
dollar.
15% decrease means the bill would be 85% of the original bill ( 100% -15% = 85%)
multiply the current bill by 85%
2100 x 0.85 = 1.785
the bill would be $1,785

Let C be the total cost;
[tex]c = 28 \times 30 = 840[/tex]
Let R be the total revenue;
[tex]r = 28 \times 25 = 700[/tex]
Let P be the net profit;

Which of the following polynomials has solutions that are not real numbers?
A
x2 - 6x +3
B
x2 + 4x +3
-*? - 9x - 10
x? + 2x +3
Answer:
Option 4 is correct.
Step-by-step explanation:
To find: Polynomial whose solution are not real numbers.
Given Polynomials are Quadratic Polynomial.
So, we can check if solution of quadratic polynomial by find & checking value of discriminant.
Standard form of Quadratic polynomial is given by
ax² + bx + c
then Discriminant, D = b² - 4ac
If, D > 0 ⇒ Solutions are distinct real numbers
if, D = 0 ⇒ Solutions are equal real numbers
if, D < 0 ⇒ Solutions are not real numbers (They are complex conjugates)
Option A:
By comparing with standard form
a = 1 , b = -6 , c = 3
D = (-6)² - 4 × 1 × 3 = 36 - 12 = 24 > 0
Thus, Solutions are Real numbers.
Option B:
By comparing with standard form
a = 1 , b = 4 , c = 3
D = (4)² - 4 × 1 × 3 = 16 - 12 = 4 > 0
Thus, Solutions are Real numbers.
Option C:
By comparing with standard form
a = -1 , b = -9 , c =-10
D = (-9)² - 4 × (-1) × (-10) = 81 - 40 = 41 > 0
Thus, Solutions are Real numbers.
Option D:
By comparing with standard form
a = 1 , b = 2 , c = 3
D = (2)² - 4 × 1 × 3 = 4 - 12 = -8 < 0
Thus, Solutions are not Real numbers.
Therefore, Option 4 is correct.

Nine more than the product of a number and eight equals four
Answer:
Step-by-step explanation:
Let the number = 'x'
Product of number and eight ⇒ 8*x = 8x
Nine more than the product of 8x ⇒add 9 to 8x
8x + 9 = 4
8x = 4 - 9
8x = -5
x = -5/8
