[tex]0.0633[/tex] is the the probability that the 6th pizza ordered is the first extra-large pizza.
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
According to question, at a certain pizzeria, it is known that 12% of orders are for extra-large pizzas.
We have to find, what is the probability that the 6th pizza ordered is the first extra-large pizza.
Probability of extra-large pizzas [tex]=\frac{12}{100}[/tex][tex]=0.12[/tex]
Probability of other pizzas[tex]=1-0.12=0.88[/tex]
Hence, the probability that the 6th pizza ordered is the first extra-large pizza[tex]=0.88^{5}[/tex]×[tex]0.12[/tex](since first 5 pizzas are other pizza)
[tex]=0.527[/tex]×[tex]0.12[/tex]
[tex]=0.0633[/tex]
Hence, we can conclude that [tex]0.0633[/tex] is the probability that the 6th pizza ordered is the first extra-large pizza.

Bao is taking a multiple choice test with a total of 100 points available. Each question
is worth exactly 2 points. What would be Bao's test score (out of 100) if she got 8
questions wrong? What would be her score if she got x questions wrong?
Answer:
84
Step-by-step explanation:
100-point test = 50 questions which are worth 2-points each.
(50 x 2 = 100)
If she got 8 wrong, this means she lost 16 points ( 8 questions x 2 points each = 16 points in total)
100 - 16 = 84
To find her score if she got x questions wrong just multiply x by 2 and subtract the answer to 100.

Eigh has a piece of rope that is 6 2/3 feet long. How do you write 6 2/3 as a fraction greater than 1.
Answer: 20/3
Step-by-step explanation:
To write 6 2/3 as a fraction greater than 1, we simply have to convert it from a mixed fraction to an improper fraction. This will be:
6 2/3 = [(6 × 3) + 2]/3
= (18 + 2)/3
= 20/3
Therefore, the answer is 20/3.

Luis, que recibe $200 mensuales desde hace un año, el mes pasado le dijo a su papá que le aumentará su mesada; el monto deseado será suficiente si tres medios de la cantidad deseada más 4100 son mayores o iguales a $700. ¿Cuánto de más quiere recibir Luis?
Answer:
Luis quiere recibir 200$ de más por mes.
Step-by-step explanation:
Para podr calcular esto, necesitamos escribir la desigualdad dada, y para ello debemos transformar el lenguaje a lenguaje algebraico.
tres medios de la cantidad deseada: 3/2 x
mas 4100 (en este caso debería ser $100, y fue un error de tipeo): + 100
son mayor o igual a $700: ≥ 700
Inecuación: 3/2 x + 100 ≥ 700
Ahora solo nos queda resolver el valor de x de esta inecuación. El resultado nos dirá cuanto quiere recibir al mes, por lo que la resta de esta cantidad con la cantidad que recibía antes nos dirá cuanto de más desea recibir:
3/2 x + 100 ≥ 700
3/2 x ≥ 700 - 100
3/2 x ≥ 600
3x ≥ 600 * 2
x ≥ 1200 / 3
x ≥ 400
Por tanto, Luis desea recibir al mes $400, lo que se traduce en que quiere recibir de más
400 - 200 = 200
Luis desea recibir de mas $200.

25 Patricia bought 5 apples and 7 bananas for $12.65. Jose bought 10 apples and 8 bananas for $18.10 at the same grocery store. What is the cost of one apple?
Answer:
Apple cost $0.85
Banana cost $1.2
Step-by-step explanation:
Given data
let the number of apples be x
and the number of bananas be y
Patricia bought 5 apples and 7 bananas for $12.65
5x+7y= 12.65----------1
Jose bought 10 apples and 8 bananas for $18.10
10x+8y= 18.10-----------2
solve 1 and 2 above
5x+7y= 12.65 X 2
10x+8y= 18.10 X 1
10x+14y= 25.3
- 10x+8y= 18.10
6y= 7.2
y= 7.2/6
y= 1.2
put y= 1.2 in 1
5x+7(1.2)= 12.65
5x+ 8.4= 12.65
5x= 12.65- 8.4
5x= 4.25
x= 4.25/5
x= 0.85
Hence each apple cost $0.85
Banana cost $1.2
Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
Answer:
f(x) = [tex]\frac{1}{16}[/tex] (x - 2)² + 2
Step-by-step explanation:
From any point (x, y ) on the parabola the focus and the directrix are equidistant.
Using the distance formula
[tex]\sqrt{(x-2)^2+(y-6)^2}[/tex] = | y + 2 | ← square both sides
(x - 2)² + (y - 6)² = (y + 2)² ← subtract (y + 2)² from both sides
(x - 2)² + (y - 6)² - (y + 2)² = 0 ← subtract (x - 2)² from both sides
(y - 6)² - (y + 2)² = - (x - 2)² ← expand left side using FOIL and simplify
y² - 12y + 36 - y² - 4y - 4 = - (x - 2)²
- 16y + 32 = - (x - 2)² ← subtract 32 from both sides
- 16y = - (x - 2)² - 32 ← divide all terms by - 16
y = [tex]\frac{1}{16}[/tex] (x - 2)² + 2

The elevation of a point in a valley is 121 feet below sea level.
Write a signed number to represent this elevation.
Answer:
-121 feet
Step-by-step explanation:
If itś 121 feet below sea level than it would be -121 feet
The signed number -121 represents an elevation of 121 feet below sea level in the context of the valley.
To represent the elevation of a point in a valley that is 121 feet below sea level as a signed number, we can use a negative sign (-) to indicate a position below sea level.
Therefore, the signed number to represent this elevation would be -121. The negative sign (-) indicates that the elevation is below sea level, and the magnitude of the number (121) represents the distance below sea level, which is 121 feet in this case.
In summary, the signed number -121 represents an elevation of 121 feet below sea level in the context of the valley.

Linda is paid double her normal hourly rate for each hour she works over 40 hours in a week. Last
week she worked 52 hours and earned $544. What is her hourly pay?
Answer:
her hourly pay is £8.50
Step-by-step explanation:
h= hourly pay
n = number of hours worked over 40 hours in a week
week pay = 40h + (n x 2 x h)
544 = 40h + 2nh
52 - 40 = 12, so n = 12
544 = 40h + 2 x 12 x h
544 = 40h + 24h
544 = 64h
544/64 = 8.5 h=8.5 (£8.50)
just to check:
£8.50 x 40 = £340
£8.50 x 2 x 12 = 204
340 + 204 = 544 yayy the answer is correct

10x + 4y = 20
13x - 4y = -66
What does x and y equal?
Answer: (-2, 10)
Explanation: Since one equation has a +4y and the other equation has
a -4y, when we add the equations together, the y's will cancel out.
So we have 23x = -46 and x = -2.
To find y, plug -2 back in for x in either of the two original equations.
I've chosen to plug -2 into the first equation to get 10(-2) + 4y = 20.
Solving from here, y = 10.
So our final answer is the ordered pair (-2, 10).
Now, check your answer.

reflection and translation.
Given:
The different transformation in the options.
To find:
The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.
Solution:
In option 1,
[tex](x,y)\to (y,x)[/tex]
It represents reflection across the line y=x.
In option 2,
[tex](x,y)\to (x,-y)[/tex]
It represents reflection across the x-axis.
In option 3,
[tex](x,y)\to (4x,4y)[/tex]
It represents dilation by scale factor 4 and the center of dilation is at origin.
In option 4,
[tex](x,y)\to (x+2,y-5)[/tex]
It represents translation 2 units right and 5 units down.
We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.
So, the perimeter of the figure and its image are same in the case of reflection and translation.
But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.
Therefore, the correct option is 3.
