What is Venn diagram?

"A Venn diagram in mathematics is a diagram that uses overlapping circles or other shapes to represent the logical relationships between two or more sets of items. "

What is probability?

"For any experiment, a probability denotes the possibility of outcome for any event."

The formula to calculate the probability of an event:

For event A, the probability of event A is,

P(A) = number of favorable outcomes/ total umber of outcomes

What is conditional probability?

"Conditional probability is the probability of an event occurring given that another event has already occurred."

The formula to calculate the conditional probability:

P(A|B) = P(A∩B)÷P(B)

For given diagram:

Let A represents a set of students playing Basketball and B represents a set of students playing Soccer

So, A = {Fran, Ian, Juan, Ella}

⇒ n(A) = 4

B = {Mickey, Marcus, Ella}

⇒ n(B) = 3

(A ∩ B) = {Ella}

⇒ n(A ∩ B) = 1

sample space: S = {Fran, Ian, Juan, Ella, Mickey, Marcus, Mai, Karl, Jada, Gabby}

⇒ n(S) = 10

Now, we calculate probability of B and A∩B.

P(B) = n(B)/n(S)

P(B) = 3/10

Also, P(A∩B) = n(A∩B) / n(S)

P(A∩B) = 1/10

So, the required probability would be,

⇒ P(A|B) = P(A∩B) ÷ P(B)

⇒ P(A|B) = (1/10) ÷ (3/10)

P(A|B) = 1/3

Therefore, P(A|B) = 1/3

Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?

Answers

Step-by-step explanation:

A. For Tavon's gift card the equation is

let y be the total amount

let x be the number of 30 day period

y=145-3.5x------1

for Tavon's second gift card the equation is

let y be the total amount

let x be the number of 30 day period

y=125-3x-------------2

B. equating 1 and 2 we have

145-3.5x=125-3x

solve for x we have

145-125=-3x+3.5x

20=0.5x

divide both sides by x we have

x=20/0.5

x= 40

put x=40 in

y=145-3.5*40------1

y=145-140

y=$5

put x=40 in

y=125-3*40------1

y=125-120

y=$5

Let x = number of bags of potato chips

Let y = the number of bags of corn chips

x+y≥100

Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation

2.50(80)+2.90(20) = 258 which is ≤$350

Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.

What is the value of x? What is the measure of angle 6? Show all of your work and/or explain your answer.

Answers

Answer:

1) 5 & 9

5=Corresponding Angle

9=Alternate Exterior Angle

2) 7 & 8

We know 4 is supplementary to 8.  Since that is true, 7 & 8 are also.

8=Corresponing angle to 4

7=Verticle angle to 8

3) We know 1 and 3 equal 180

x-20+x+40=180

2x+20=180

2x=180-20

2x=160

x=80

<2=X+20

=80+20

=100

Angle 2 is the same as angles 5 and 6 added together.

We know angle 5 is the same as angle 1 (corresponding angles).

<1=X-20

=80-20

=60

Now that we know <2=100 and <5=60, we can figure out <6

100-60=40

<6=40°

Step-by-step explanation:

1) 5 & 9

5=Corresponding Angle

2) 7 & 8

We know 4 is supplementary to 8.  Since that is true, 7 & 8 are also.

8=Corresponing angle to 4

7=Verticle angle to 8

3) We know 1 and 3 equal 180

2x+20=180

2x=180-20

Angle 2 is the same as angles 5 and 6 added together.

We know angle 5 is the same as angle 1 (corresponding angles).

Tom es el gerente del departamento de delicatessen en una tienda de comestibles. Debe programar que los empleados trabajen en el departamento durante al menos 260 horas a la semana. Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Escriba una desigualdad para determinar nnn, el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.

Answers

Answer:

La desigualdad para determinar el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana es 20+40*n ≥ 260. Resolviendo al menos 6 empleados deben trabajar a tiempo completo.

Step-by-step explanation:

Una inecuación es una desigualdad entre letras (incógnitas) y números relacionados por  operaciones aritméticas. Su conjunto solución es el conjunto de números reales que la satisfacen. En una desigualdad, dos expresiones algebraicas están conectadas a través de los signos: mayor que >, menor que <, menor o igual que ≤ y mayor o igual que ≥.

Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.

Sabiendo que x representa la cantidad de trabajadores a medio tiempo  y n la cantidad de trabajadores a  tiempo completo, entonces  20*x+40*n representa la cantidad de horas que todos los empleados trabajan semanalmente. Si los empleados trabajen al menos 260 horas a la semana, esto significa que la cantidad de horas que todos los empleados trabajan a la semana debe ser mayor o igual a 260 horas. Entonces:

20*x+40*n ≥ 260

Si Tom tiene un empleado a tiempo parcial, entonces la cantidad de trabajadores a medio tiempo x debe tener un valor de 1. Entonces:

20*1+40*n ≥ 260

20+40*n ≥ 260

40*n ≥ 260 -20

40*n ≥ 240

n ≥ 240 ÷40

n ≥ 6

Entonces 6 empleados o más deben trabajar a tiempo completo.

Marcus reads in a magazine article that 62% of teenagers prefer Batman over Iron Man. He decides to test this so he takes a simple random sample of 50 people at Wal-Mart on a Sunday afternoon. What is the probability that he finds exactly 40 Batman fans? Round to the nearest thousandth.

Answers

Answer:

The probability is 0.003

Step-by-step explanation:

If 62% prefers Batman, the percentage that prefers Iron man will be (100-62)% = 38%

So the probability of finding a teenager that likes batman will be 62/100 = 0.62

The probability of finding a teenager that prefers iron man will be 38/100 = 0.38

Now, we want to find the probability that out of 50 people at Walmart on a Sunday, exactly 40 prefers Batman

We can use the Bernoulli approximation of the binomial theorem ;

let probability of liking Batman be q and that of iron man be q

Thus the approximation will be;

P(X = 40) = 50 C 40 (0.62)^40 (0.38)^10

= 0.003200147531

To the nearest thousandth, this is 0.003

Consider the square arrangements below in relation to the girls' expressions, where n represents the figure number.
Determine whether Maya, Kiana or both girls are correct in their given expressions. Justify your response.

The evaluation of your response will be based on the following criteria.

Answers

Answer:

Answer:

Kaya's answer is correct.

Step-by-step explanation:

The number of dots in successive figures are

8, 16, 24.

So Kaya's solution 8n is correct.

When n = 1, first square = 8*1 = 8 dots

n = 2: second square = 8*2 = 16

n = 3, 3rd square = 8*3 = 24.

If I have interpreted Kianna's formula correctly

for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2

Eve knits scarves for her online store. This week she has already knitted 9 scarves. There are 2 days left in the work week. She set a goal for herself to knit at least 17 scarves and at the most 19 scarves this week. Eve wants to know how many scarves she should knit each day to meet her goal.

Which inequality represents the given situation?


A.
17 ≤ 2x - 9 ≤ 19
B.
17 ≥ 2x + 9 ≥ 19
C.
17 ≤ 2x - 9 ≥ 19
D.
17 ≤ 2x + 9 ≤ 19

Answers

we can eliminate A and C first because A says 17 would be the most or equal to when we know she said 19 would be the most and C says that 19 would be the least or equal to. so the answer would be D. but it’s D because B says 17 would be the most or equal while saying 19 would be the least and we know that’s not true.

TL;DR: the answer is D

The amount of money left in Alma's bank account is expressed by the linear equation y = -27x + 577, where x represents the number of weeks and y represents the amount of money left in her account. After how many weeks will Alma have $145 left in her account? 12 weeks 16 weeks 22 weeks 26 weeks

Answers

Given:

The linear equation is

[tex]y=-27x+577[/tex]

where x represents the number of weeks and y represents the amount of money left in Alma's account.

To find:

The number of weeks in which Alma have $145 left in her account.

Solution:

We have,

[tex]y=-27x+577[/tex]

Substitute y=145, we get

[tex]145=-27x+577[/tex]

Subtract both sides by 577.

[tex]145-577=-27x[/tex]

[tex]-432=-27x[/tex]

Divide both sides by -27.

[tex]\dfrac{-432}{-27}=\dfrac{-27x}{-27}[/tex]

[tex]16=x[/tex]

So, the number of required weeks is 16. Therefore, the correct option is B.
