If 3 marbles are drawn from a bag of 12 marbles consisting of three red, four white and five blue, without returning them to the

FinnZ [79.3K]

Answer:

The probability of that happening is 1/22

Step-by-step explanation:

In order to find the probability, you need to start by finding the probability for each step. The probability of the first one being red is the number of red marbles divided by the total number of marbles.

3 red / 12 total.

3/12

1/4

Now the chance that the second is white is the total number of white marbles divided by how many are left in the bag.

4 white / 11 left

4/11

Lastly, the chance of the last one being blue is the number of blue marbles divided by the amount of total marbles left after two pulls.

5 blue/ 10 left

5/10

1/2

Now to find the overall probability of all 3 happening, we multiply all 3 probabilities together.

1/4 * 4/11 * 1/2 = 1/22

HELP what's the distance for this question?

jeyben [28]

Answer:

$Distance = 38.57ft$

Step-by-step explanation:

Given

$Base = 60$

$\theta = 50$

Required

The distance between the top and John

The distance is calculated using:

$sin\alpha = \frac{Distance}{Base}$

Where

$\alpha = 90 - \theta$ --- the angle between the diagonal line and the vertical line

$\alpha = 90 - 50$

$\alpha = 40$

So, we have:

$Sin(40) = \frac{Distance}{60}$

$Distance = 60 * sin(40)$

$Distance = 60 * 0.6428$

$Distance = 38.57ft$

$Distance = 986 * tan(38)$

$Distance = 986 * 0.7812$

$Distance = 770ft$ <em> --- approximated</em>

A family of 3 shares the minutes on a cell phone plan. Suppose the plan allows for 675 minutes per month. How many minuets are l

Olegator [25]

Let's come up with variables to substitute and make an equation.

T = total number of minutes
P = number of minutes used by each person in the phone plan
R = remaining minutes per month

R=T-3P

Now that we have an equation, we can substitute the numbers we are given in the problem to find the final solution.

R= 675- 3(250)
R= 675- 750
R= -75 minutes

There are no remaining minutes, and in fact, the people on the phone plan have used 75 extra minutes than provided for in their phone plan.

. The exterior angles of a triangle are (2x+10)⁰, (3x-5) ⁰ and (2x+40) ⁰.

Pepsi [2]

The exterior angles of a triangle are (2x+10)⁰, (3x-5) ⁰ and (2x+40) ⁰

To get interior angle for each , subtract from 180

$180-(2x+10)=170-2x\\180-(3x-5)=185-3x\\180-(2x+40)= 140-2x$

Sum of interior angles = 180

$170-2x+185-3x+140-2x=180$

$-7x+170+185+140=180\\-7x+495=180\\-7x+495-495=180-495\\-7x=-315\\x=45$

$170-2x=170-2(45)=80\\185-3x=185-3(45)=50\\140-2x=140-2(45)=50$

Answer: x=45

smaller angle =50 degree

largest interior angle = 80 degrees
