La probabilidad de que al tirar un dado, salga 1, es de 1/6. La probabilidad de que salga 3, es de 1/6. Calcular la probabilidad de que al tirar un dado, salga 1 o 3.
Answers
Respuesta. La probabilidad de sacar um 3 seria de 16.66% osea un sexto ,de sacar un numero par es de tres sexto osea del 50% y de sacar un numero impar es de tres sexto osea 50% igual ke los pares y de sacar un numero menor k 7 es de 6 sobre 6 osea 100%.
El valor uno corresponde al suceso seguro: lanzamos un dado al aire y la probabilidad de que salga cualquier número del 1 al 6 es igual a uno (100%). El resto de sucesos tendrá probabilidades entre cero y uno: que será tanto mayor cuanto más probable sea que dicho suceso tenga lugar.

Six friends share 3/4 of a pound of roasted almonds. What fraction of a pound does each friend receive
Answers
Answer: 1/8 pounds of roasted almonds
Step-by-step explanation:
There are six friends and each of them are to receive and equal piece out of a 3/4 pound of roasted almonds.
The almonds each friend will get will therefore be the 3/4 pack divided by 6:
= 3/4 ÷ 6
= 3/4 * 1/6
= 3/24
= 1/8 pounds of roasted almonds
When dividing by a number, you can instead multiply by the inverse of that number.
In the figure, triangle CAE is an enlargement of triangle CBD with scale factor of 4/3. The area of the smaller triangle is 9cm2. What is the area of the bigger traingle
Answers
Answer:
16 cm^2
Step-by-step explanation:
Given
[tex]\triangle CAE[/tex] -- Bigger Triangle
[tex]\triangle CBD[/tex] -- Smaller Triangle
[tex]k = \frac{4}{3}[/tex] --- Scale factor
Area of CBD = 9
Required
Determine the area of CAE
The area of triangle CBD is:
[tex]A_1 = \frac{1}{2}bh[/tex]
[tex]\frac{1}{2}bh = 9[/tex]
The area of CAE is:
[tex]A_2 = \frac{1}{2}BH[/tex]
Where:
[tex]B = \frac{4}{3}b[/tex] and
[tex]H = \frac{4}{3}h[/tex]
The above values is the dimension of the larger triangle (after dilation).
So, we have:
[tex]A_2 = \frac{1}{2}*\frac{4}{3}b * \frac{4}{3} * h[/tex]
[tex]A_2 = \frac{1}{2}*\frac{4}{3} * \frac{4}{3} *b* h[/tex]
[tex]A_2 = \frac{1}{2}*\frac{16}{9} *b* h[/tex]
Re-order
[tex]A_2 = \frac{16}{9}*\frac{1}{2}* b* h[/tex]
[tex]A_2 = \frac{16}{9}*\frac{1}{2}bh[/tex]
Recall that:
[tex]\frac{1}{2}bh = 9[/tex]
[tex]A_2 = \frac{16}{9}*9[/tex]
[tex]A_2 = 16[/tex]
Hence, the area is 16 cm^2
What are the points on y-axis which are at a distance of 4 units from 4x+3y=12
Answers
Given:
The equation of line is
[tex]4x+3y=12[/tex]
To find:
The points on y-axis which are at a distance of 4 units from the given line.
Solution:
The point lie on the y-axis. So, their x-coordinate must be zero.
Let the points are in the form of (0,k).
The distance between a point [tex](x_0,y_0)[/tex] and a line [tex]ax+by+c=0[/tex] is
[tex]d=\dfrac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}[/tex]
The given equation can be written as
[tex]4x+3y-12=0[/tex]
The distance between (0,k) and [tex]4x+3y-12=0[/tex] is 4 units.
[tex]4=\dfrac{|4(0)+3(k)-12|}{\sqrt{4^2+3^2}}[/tex]
[tex]4=\dfrac{|0+3k-12|}{\sqrt{16+9}}[/tex]
[tex]4=\dfrac{|3k-12|}{\sqrt{25}}[/tex]
[tex]4=\dfrac{|3k-12|}{5}[/tex]
Multiply both sides by 5.
[tex]20=|3k-12|[/tex]
[tex]\pm 20=3k-12[/tex]
[tex]12\pm 20=3k[/tex]
[tex]\dfrac{12\pm 20}{3}=k[/tex]
Now,
[tex]k=\dfrac{12-20}{3}\text{ and }k=\dfrac{12+20}{3}[/tex]
[tex]k=\dfrac{-8}{3}\text{ and }k=\dfrac{32}{3}[/tex]
Therefore, the two points are [tex]\left(0,\dfrac{-8}{3}\right)\text{ and }\left(0,\dfrac{32}{3}\right)[/tex].

Un jugador de basquetbol ha realizado los 2/5 del número de puntos conseguidos por su equipo en un partido y otro la tercera parte del resto. Si los demás jugadores han conseguido 34 puntos, ¿cuántos puntos obtuvo el equipo en el partido?
Answers
Answer:
85 points
Step-by-step explanation:
Let :
Total points made by team = x
Points made by the player :
2/5 of total = 2x/5
1/3 of the rest :
Points left = x - 2x/5= 3x /5
1/3 of 3x /5
1/3 * 3x / 5
= 3x / 15 = x / 5
Points made by rest of the players = 34 points
Hence, total points scored, x :
x = 34 + 2x /5 + x /5
x = 34 + 3x / 5
x - 3x/5 = 34
2x / 5 = 34
2x = 34 * 5
2x = 170
x = 170 / 2
x = 85
Total points scored by team = 85

Charlie runs laps around a track. The table shows how long it takes him to run different numbers of laps. How long would it take Charlie to run 9 laps?
Number of laps 2, 4, 6, 8, 10
Time (min) 16, 32, 48, 64, 80
Answers
Answer:
72
Step-by-step explanation:
It would take Charlie 72 minutes to run 9 laps. To solve the question find how long it takes to run 1 lap. Do this by dividing the number of minutes by the number of laps ran. For example, 16/2 equals 8, which means it took him 8 minutes to run one lap. To check you can divide the other values, like 32/4= 8 and 48/6 = 8. Then, multiply 8*9 it see how long it takes for him to run 9 laps. Therefore, the answer is 72 because 8*9=72.

A new phone costs $230 and the sales tax rate is 7%. What is the total cost of the camera after tax?
Answers
That's a question about percentage.
One way to represent percentage is using decimal number. In this way, 1 is equivalent to 100% and the other less percentages using numbers between 0 and 1.
Examples:
90% is equivalent to 0,90.5% is equivalent to 0.05. It's not 0.5 because 0.5 is equivalent to 50%.13.17% is equivalent to 0.1317.245% is equivalent to 2.45.If we want to know the percentage of a number, we should multiplacate the number by the porcentage in the decimal number form.
Examples:
55.90% of 200 is equal to: [tex]200 \times 0.5590 = 111.8[/tex]360% of 88 is equal to: [tex]88\times 3.6 = 316.8[/tex]In our problem, we have a phone with a increase of 7%. To solve that, it's important to perceive that $230 is equal to 100% and with a increase of 7%, we will pay 107%.
107% in the decimal number form is 1.07. With that information, we should multiplicate 1.07 by the original value and we will find the answer.
We know that [tex]230\times 1.07 = 246.1[/tex], therefore, the total cost of the phone after tax is $246.1.
I hope I've helped. :D
