A bag contains 8 black marbles, 16 white marbles, 14 red marbles, and 10 green marbles. A marble is drawn at random from the bag. What is the probability that the marble drawn will not be white? 1/3. 2/3. 3/4. 15/16

### Answers

**Answer:**

2/3

**Step-by-step explanation:**

total marbles is (8 black+ 16 white + 14 red +10 green) = 48

no white cmarbles ( 8+14+10) = 32

32/ 48 = 2/3

Which shows the equation of the line containing the point (–2, 6) and having a slope of 3 in slope-intercept form?

3y = x + 20

y=3x−20

y = 3x + 12

y=−32x+3

### Answers

**Answer:**

y=3x+12

**Step-by-step explanation:**

Use this formula: y-y1=m(x-x1)

(y-Your y point=slope(x-Your x point)

Point= (-2, 6), Slope= 3

(Anything negative, you add. Anything positive, you subtract.)

Plug in your values: y-6=3(x+2)

distribute: y-6=3x+6

Add six to both sides of the equation:y-6(+6)=3x+6(+6)

We get our answer: y=3x+12

**What is Combination?**

A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Since, the order matters, we use the permutations formula to solve this question.

**Permutations formula:**

The number of possible permutations of x elements from a set of n elements is given by the following formula:

ⁿPₓ = n! / (n - x)!

In this question:

The **first seat** is Jose's.

The remaining four are **organized **among the other 7 members. So

There is no **difference**. So, 7 people can be sit in different ways as;

ⁿPₓ = n! / (n - x)!

⁷P₄ = 7! / (7 - 4)!

= 7! / 3!

= 840

So, the correct answer is, 840

The square root of X+6= X-6

### Answers

**Answer:**

x = 10

**Step-by-step explanation:**

I assume you mean

sqrt(x + 6) = x - 6

let's square the whole equation :

x + 6 = (x - 6)² = x² - 12x + 36

x² - 13x + 30 = 0

the general solution to a quadratic equation is

x = (-b ±sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = -13

c = 30

x = (13 ±sqrt(13² - 4×1×30))/(2×1) =

= (13 ±sqrt(169 - 120))/2 = (13 ±sqrt(49))/2 =

= (13 ± 7)/2

x1 = (13 + 7)/2 = 20/2 = 10

x2 = (13 - 7)/2 = 6/2 = 3

for x = 10 we get for the original equation

sqrt(10+6) = 10-6 = 4

sqrt(16) = 4

4 = 4

so, x = 10 is a valid solution.

for x = 3 we get

sqrt(3 + 6) = 3 - 6 = -3

sqrt(9) = -3

3 = -3

so, this (x = 3) counts as an invalid solution, because most teachers nowadays expect the square root symbol operation to deliver only the positive solution.

although a square root is actually representing both : the positive AND the negative solution, because the negative number multiplied by itself is the same result as the positive number multiplied by itself.

so, actually

sqrt(9) = -3

± 3 = -3

is still correct and valid. but not what your teacher expects most likely.

in my younger days only the square root of a negative number counted as invalid operation (in the space of Real numbers, of course), and therefore only a solution leading to a square root of a negative number was an invalid solution.

Fred figured out the volume of the glass is 141.37cm. Show work

### Answers

To solve this problem, we have to calculate the **volume **of a **hemisphere **and the **volume** of a **cylinder** and add them together. The **volume** of the glass can be only be calculated when we find the **volume** of the **hemisphere **and the **volume **of the** cylinder **and then add then up together.

Volume of a Hemisphere

The volume of a hemisphere is given as

[tex]v = \frac{2}{3} * \pi * r^3[/tex]

Data

r = 3cm

Let's substitute the values into the equation and solve.

[tex]v = \frac{2}{3} * \pi * r^3\\v = 56.556cm^3\\[/tex]

Volume of a Cylinder

The formula of **volume** of a **cylinder** is

[tex]v = \pi r^2 h[/tex]

data given

h = 3cmr = 3cm

Let's substitute the values into the equation and solve

[tex]v = \pi r^2 h\\v = 3.142 * 3^2 * 3\\v = 84.834cm^3[/tex]

Let's add both **volumes** together so we have the **volume **of the glass cup

[tex]56.556 + 84.834 = 141.39cm^3[/tex]

The **volume** of the glass can be only be calculated when we find the **volume** of the **hemisphere **and the **volume **of the** cylinder **and then add then up together.
