Mean is the average
Without outlier:
one 7
two 8
two 9
four 10
=[7+(2*8)+(2*9)+(4*10)] / 9
= (7 + 16 + 18 + 40) / 9
= 81/9

What makes this undefined.
The expression is undefined when x=3 or -3
Solution:An expression is undefined when it's divided by 0.In order to make the denominator equal 0, we need to subtract 9-9. Notice that x is squared.So x times itself should equal 9. What number is it?That's right, 3.So we have9-(3)^2=9-9=0There's also another solution: x=-3 (-3•(-3)=9Hope it helps.
Do comment if you have any query.
Answer: The expression is undefined when x is 3 or -3
Step-by-step explanation:
The denominator of a fraction can never be 0 because you cannot divide by 0. So all we have to do is determine the value of x when the denominator is equal to 0.
[tex]9-x^{2} =0\\[/tex]
We want [tex]x^2[/tex] to be positive so divide everything by -1
[tex]9-x^{2} =0\\\\\frac{9-x^{2}}{-1}=\frac{0}{-1} \\-9+x^2=0\\x^2-9=0[/tex]
Use difference of two squares (DOTS) to factor
[tex]x^2+9=0\\(x+3)(x-3)=0[/tex]
So x cannot be 3 or -3

Abraham is three times as old as Sylvia.
In eight years' time, Abraham will be
twice as old as Sylvia. How old is
Abraham?
Answer:
24 years old
Step-by-step explanation:
let x = age of abraham, y = age of sylvia
x = 3y
x + 8 = 2y+16 => (2(y+8))
3y + 8 = 2y + 16
y = 8
x = 3(8)
x = 24

How many angles are formed by intersecting roads? Number the angles
Answer:
When two lines intersect and form 4 angles at the intersection, the two angles that are opposite each other are called “opposite angles” or “vertical angles” and these vertical angles are “congruent” – meaning they have the same shape and size.
Step-by-step explanation:
please huryyyyyyyyyyyyyyyyyyyyyy!!!!!!!!!!
Answer:
(x-1)^2 + (y-1)^2 = 16
Step-by-step explanation:
center, (h,k) = (1,1) radius = 4
put in standard form for a circle
(x-h)^2 + ( y-k)^2 = r^2
Scoopers ice cream shop sells one scoop of ice cream for $1.60. They sell three scoops for $4.80. How much money is needed to buy two scoops of ice cream?
Answer:
$3.20
Step-by-step explanation:
1.60 x 2 = $3.20
You need $3.20 to buy 2 scoops of ice cream.
Answer:
Step-by-step explanation:
Since the cost of one ice cream scoop is $1.60, you would either have to add $1.60 two times, or multiply 1.60x2.
$1.60+$1.60 or 1.60x2=$3.20.
Therefore, the answer to the question would be “$3.20 would be needed to buy two scoops of ice cream.”

[tex] \frac{{b}^{4} }{ {a}^{2} {c}^{2} } [/tex]
explanation:
There's 4 as in the denominator which cancels out the 2 in the numerator. Thus leaving you with 2 as in the denominator. Then there's only 1 b I the denominator which is canceled out by the ones in the numerator, leaving you with only 4 b's in the numerator. Finally there is only 1 c in the numerator which is canceled out by the ones in the denominator. Thus leaving you with 2 c's in the denominator.

Answer:

Let the missing length is x.
According to Pythagorean, we have the following equation

Missing length = 4 in
Step-by-step explanation:
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = 3 inb = ?c = 5 inSubstitute given values into the formula and solve for ?:
⇒ 3² + ?² = 5²
⇒ 9 + ?² = 25
⇒ ?² = 25 - 9
⇒ ?² = 16
⇒ ? = √16
⇒ ? = 4 in

- You work in the human resources department of a
company. Per the employee benefits package, each
employee earns 1 and 1/2 vacation days per month. You
need to calculate the total number of vacation days
that an employee earns in a year. How many total
vacation days will an employee earn in a year?
Answer:
18 Days Off
Step-by-step explanation:
Firstly, to solve this question you have to identify how many months are in a year; that's 12. So now we know:
Each employee can take 1 1/2 days off in a monthThere are 12 months in a yearMaking a formula for calculation is the best way to do this, especially since we now have all of the information needed to answer.
VacationDays=1 [tex]\frac{1}{2}[/tex] × 12
Vacation days are the total number of vacation days in a year.
∴VD= 1 [tex]\frac{1}{2}[/tex] x 12
VD= 18
∴Total vacation days equal 18
Each employee gets 18 vacation days in a year.

please show work 2. Which equation represents the line whose slope is 6 and whose y-intercept is 2?
A. y = 2x + 6
B. 2y + 6x = 0
C. y = 6x + 2
D. y + 2x = 6
We are given the line's slope and the line's y-intercept (the point where the line touches the y-axis)
It's easier to write the equation in Slope-Intercept Form, which looks like so:-
[tex]\boxed{y=mx+b}[/tex]
where m -> slope of the line & b -> y-intercept
Instead of m, you should plug in 6:-
y=6x+b
Instead of b, you should plug in 2:-
y=6x+2 ✓

Find the area of each regular polygon below. Round values to the nearest 0.01. Show work for all steps clearly.
The area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively.
Data;
apothem = 15Area of a HexagonThe area of a hexagon with apothem 15 can be calculated by first finding the length of the side of the hexagon.
Length of hexagon can be found using trigonometric ratio;
[tex]a = x\sqrt{3}[/tex]
Making x the subject of formula
[tex]x = \frac{a}{\sqrt{3} }\\x = \frac{15}{\sqrt{3} }\\x = 8.660[/tex]
And then the length of the side is 2x
[tex]s = 2 * 8660 = 17.32[/tex]
The perimeter of the hexagon is;
[tex]p = 6s \\p = 6 * 17.32=103.92[/tex]
And the area is given as
[tex]A = \frac{1}{2} * perimeter * apothem\\A = \frac{1}{2} * 103.92 * 15\\A = 779.4unit^2[/tex]
The area of the hexagon is 779.4 squared unit.
Area of the pentagonThe area of the pentagon can be found using several methods, but we can simply find the angle between the sides if we divide the pentagon into 10 pieces and then substitute the formula.
Total area of a pentagon is 360 degree.
[tex]\theta = \frac{360}{10} = 36^0\\[/tex]
The area of a pentagon is given as
[tex]A = \frac{5s^2}{4 tan \theta} \\A = \frac{5 * 7^2}{4* tan36} \\A = 84.303cm^2[/tex]
The area of the pentagon is 84.303cm^2
From the calculations above, the area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively

When solving this equation for x, what would you do next?
Answer: A. Distribute the 3 outside of the parathesis to everything inside the parenthesis
We use the order of operations, also known as PEMDAS.
Since there is a variable inside the parenthesis, we cannot add/subtract 4. This means the next step is to distribute.
After distributing, the equation looks like this and we can solve it from there:
