Answer:
a) 9/20 or 45%
b) 2/5 or 40%
c) Answer choice 1
Step-by-step explanation:
a) During Linda's experimentation, she spinned the spinner a total of 18+14+8=40 times. Out of those, 18 landed on grey. Based on her results, the experimental probability is 18/40=9/20 or 45%.
b) Assuming the spinner is fair, since there are 5 total possible colors to land on and 2 of them are gray, the probability is 2/5 or 40%.
c) As time goes on and the spinner is spinned more and more often, it will continue to approach the theoretical probability, because that is the likelyhood every time that the arrow lands on grey. Hope this helps!

A parabola has a vertex at (-3,2). Where is the axis of symmetry?
Answer:
The axis of symmetry of the parabola with a vertex at (-3, 2) is at
x = -1/2
Step-by-step explanation:
Given a quadratic function (parabola) of the form:
y = ax² + bx + c
The axis of symmetry of the function is a vertical line that divides the parabola into two congruent halves. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.
This is given as x = -b/2a
We are given a parabola with vertex at (-3, 2). The quadratic function corresponding to this is
y = (x -(-3))(x - 2)
= (x + 3)(x - 2)
= x² - 2x + 3x - 6
y = x² + x - 6
Here, a = 1, b = 1, and c = -6
The axis of symmetry is at
x = -b/2a
= -1/2(1)
= -1/2
The axis of symmetry of the given parabola should be [tex]y-2=m(x+3)[/tex] for all cases. And, for horizontal and vertical orientation, the equation of the axis of symmetry should be y=2 and x=-3, respectively.
Given information:
The parabola has vertex at (-3,2).
It is required to get the axis of the parabola.
In general, the parabola with vertex (3,2) can have any axis of symmetry based on the orientation of the parabola. The only condition is that the axis must pass through the point (3,2).
The general equation of the axis of symmetry with slope m (orientation) should be,
[tex]y-(2)=m(x-(-3))\\y-2=m(x+3)[/tex]
So, the general equation of the axis of symmetry of the given parabola should be [tex]y-2=m(x+3)[/tex].
In normal cases, the orientation of the parabola is either horizontal or vertical.
In case of vertical orientation, the slope should be infinite or 1/0. So, the equation of axis will become,
[tex]0(y-2)=(x+3)\\x=-3[/tex]
In case of horizontal orientation, the slope should be infinite or 1/0. So, the equation of axis will become,
[tex](y-2)=0(x+3)\\y=2[/tex]
Therefore, the axis of symmetry of the given parabola should be [tex]y-2=m(x+3)[/tex] for all cases. And, for horizontal and vertical orientation, the equation of axis of symmetry should be y=2 and x=-3, respectively.

Answer:
4.5
Step-by-step explanation:
It's the right answer 2 is wrong.
The value of the third-term arithmetic sequence will be 4.5. Then the correct option is A.
What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
From the graph, the first term is 1.5 and the common difference is given as,
d = 3 - 1.5
d = 1.5
Then the arithmetic equation is given as,
aₙ = 1.5 + (n - 1)(1.5)
The value of the third term will be given as,
a₃ = 1.5 + (3 - 1)(1.5)
a₃ = 1.5 + 3
a₃ = 4.5
The value of the third-term arithmetic sequence will be 4.5. Then the correct option is A.

A rock group plans to travel for a total of 27 weeks, making three concert stops. They will be in Japan for 2 more weeks than they will be in Australia. Their stay in Sweden will be 2 weeks shorter than that in Australia. How many weeks will they be in each country?
Answer:
They spent 9 weeks in Australia, 11 weeks in Japan and 7 weeks in Sweden.
Step-by-step explanation:
A rock group plans to travel for a total of 27 weeks, making three concert stops in Japan, Australia and Sweden.
Let the number of weeks spent in Sweden be s.
Let the number of weeks spent in Japan be j.
Let the number of weeks spent in Australia be a.
This means that:
s + j + a = 27___________(1)
They will be in Japan for 2 more weeks than they will be in Australia. This means that:
j = a + 2 ______________(2)
Their stay in Sweden will be 2 weeks shorter than that in Australia. This means that:
s = a - 2 ______________(3)
We can replace s and j in (1) with (2) and (3):
=> a - 2 + a + 2 + a = 27
Collecting like terms:
a + a + a - 2 + 2 = 27
3a = 27
a = 27 / 3 = 9
The number of weeks they will spend in Australia is 9 weeks.
Putting this value of a in (2) and (3):
j = 9 + 2 = 11
and
s = 9 - 2 = 7
Therefore, they will spend 11 weeks in Japan and 7 weeks in Sweden.

THIS IS A QUESTION FOR WOLLFGIRL Write out 2-4 sentences about which advertisement would give you the "best deal"
Answer:
answers are highlighted below! I hope this helps! please do not copy my work! ^-^ :)
Step-by-step explanation:
okay, on the first one we are told we have 15% off of $729.99
which then takes off about $109.50
after we subtract the $109.50 from the $729.99 we are left with $620.49, that's not including tax
sales ax is 8.25% or $51.19 that comes out to equal $671.69
so we can conclude that the big tv sale at the big box store is equal to the amount of $671.69
on the second one, its normally $699.99
we have the coupon for $100 off of that price so that leaves us with $599.99
but we have the $50 charge for delivery. so now its at $649.99
now we need to determine the price after tax. the price of tax is $53.62
add the tax amount to $649.99 to get $703.61
$703.61
the initial price of the tv is $734.95
$150 in rebate (refund)
$734.95 - $150 = $584.95
now we need to find the price including the delivery cost
$584.95 + $35 = $619.95
now lets find the tax price
$51.15
After Tax Price: $671.10
The TV from the Electronic Warehouse is the best option. You pay only $671.10! The prices from the two other stores are $703.61 and $671.69.
We are paying .59 cents less than one of the TV's, and we are also paying $32.51 less than the other TV! So the best option would be the TV from the Big Box store!
Determine if the following system of equations has no solutions, infinitely many
solutions or exactly one solution.
x + 6y = -5
3x + 18y = -15
Answer:
infinitely many solutions
Step-by-step explanation:
x + 6y = -5
3x + 18y = -15
Multiply the first equation by 3
3(x + 6y) = -5*3
3x + 18y = -15
The two equations are identical. This means they have infinite solutions along the line x+6y = -5

Answer:
y = 4x-7
Step-by-step explanation:
We have a slope and a point
m = 4 (2,1)
Using the slope intercept form of the equation
y = mx+b
y = 4x+b
From the point x=2 and y =1
1 = 4(2)+b
1 = 8+b
Subtract 8 from each side
1-8 =8-8+b
-7 = b
We can write the equation by using m=4 and b = -7
y = 4x-7
Answer:
y = 4x - 7
Step-by-step explanation:
y = mx + b
y = 4x + b
1 = 4(2) + b
b = 1 - 8
b = -7
y = 4x - 7
Program the VR Robot to drive forward 6 grid squares, turn around, and drive back 6 grid squares. How many degrees did you have to turn to face the way you came? What is the total distance traveled? Use a calculator and/or pencil and paper to find out.
Final answer:
The VR Robot will need to turn 180 degrees to face the original direction after driving forward 6 grid squares. It then drives back the same distance, totaling 12 grid squares or units of distance traveled.
Explanation:
To program a VR Robot to drive forward 6 grid squares, turn around, and drive back 6 grid squares, we need to calculate the total degrees turned and the total distance traveled. When turning to face the way it originally came from, the robot will need to turn 180 degrees.
This is because a half-circle, or a complete about-face turn, is 180 degrees. For the total distance traveled, if each grid square is a standardized distance (let's assume 1 unit distance per grid square), then driving forward 6 grid squares and back would accumulate a total of 12 grid squares or units.
The total distance traveled by the VR robot is 12 units. Turning around to face the original direction is simply a 180-degree turn, whether this is done to the left or to the right.

hope this helped you
Final answer:
The given expression 5a−5a²−10a⁴ is factored as a product by factoring out the common factors, resulting in 5a(1 - a - 2a³).
Explanation:
To write the expression 5a−5a²−10a⁴ as a product, we need to factor out the common factors in each term. The term with the lowest exponent in 'a' is '5a', which indicates we can factor out 'a' from the entire expression. However, we can also factor out a '5' since it is common to all terms. Here are the steps:
First, identify the common factors in the terms which are '5' and 'a'.Factor out '5a' from each term in the expression.Doing this, we get: 5a(1 - a - 2a³)
The expression can now be expressed as the product of '5a' and '(1 - a - 2a³)'.
