Box A contains 3 red and 2 blue marbles while Box B contains 2 red and 8 blue marbles. A fair coin is tossed. If the coin turns up heads, a marble is chosen from Box A; if it turns up tails, a marble is chosen from Box B.

A. Find the probability that a red marble is chosen.

B. Referring to above information, suppose that the person who tosses the coin does not reveal whether it has turned up heads or tails (so that the box from which a marble was chosen is not revealed) but does reveal that a red marble was chosen. What is the probability that Box A was chosen (i.e., the coin turned up heads)?

**Answer:**

A. [tex]\frac{4}{10}[/tex]

B. [tex]\frac{3}{4}[/tex]

**Step-by-step explanation:**

**Given -** Box A contains 3 red and 2 blue marbles while Box B contains 2

red and 8 blue marbles. A fair coin is tossed. If the coin turns up

heads, a marble is chosen from Box A; if it turns up tails, a marble

is chosen from Box B.

**To find -** A. Find the probability that a red marble is chosen.

B. Referring to above information, suppose that the person who

tosses the coin does not reveal whether it has turned up

heads or tails (so that the box from which a marble was

chosen is not revealed) but does reveal that a red marble was

chosen. What is the probability that Box A was chosen (i.e.,

the coin turned up heads)?

**Proof -**

As given ,

Box A : 3 red marbles and 2 blue marbles.

Box B : 2 red marbles and 8 blue marbles.

a.)

As we have to find the probability that a red marble is chosen.

A red marble is chosen in two different ways - either it can be from Box A or Box be .

If Box A is chosen , then Probability of red ball is [tex]\frac{3}{5}[/tex]

If Box B is chosen , Then Probability of Red ball is [tex]\frac{2}{10} = \frac{1}{5}[/tex]

Now,

Probability of Box A is Chosen = [tex]\frac{1}{2}[/tex]

Probability of Box B is chosen = [tex]\frac{1}{2}[/tex]

∴ we get

Probability that a Red marble is chosen = [tex]\frac{1}{2}[/tex]×[tex]\frac{3}{5}[/tex] + [tex]\frac{1}{2}[/tex]×[tex]\frac{1}{5}[/tex] = [tex]\frac{3}{10} + \frac{1}{10} = \frac{4}{10}[/tex] = 0.4

b.)

Now,

Probability that Box A is chosen given that Red marble is chosen is

P(Box A | Red marble ) = [tex]\frac{(\frac{3}{5})(\frac{1}{2}) }{(\frac{3}{5})(\frac{1}{2}) + (\frac{1}{5})(\frac{1}{2})} = \frac{\frac{3}{10} }{\frac{3}{10} + \frac{1}{10} } = \frac{\frac{3}{10} }{\frac{4}{10}}[/tex] = [tex]\frac{3}{4}[/tex]

**Answer:**

y=-(x+11)(x-23)

**Step-by-step explanation:**

y=-(x+11)(x-23)

use the x intercepts they give you, and make it the opposite i.e. if it positive, then make it negative if it is negative make it positive

i.e. -11 equals 11

thus (x+11)

then, the graph is concave down, so it is negative at the front

On a scale drawing of a building, 1 inch represents 14 feet. If the height of the actual building is 49 feet, what is the height of the drawing?

enter the answer in the text box below

____ in.

The answer is 3.5 inches for K12 test

All i did was see what coud make 49 feet.

since 1 inch = 14 feet then i did 3 x 14 which got 42.

I then just shuffled around numbers and got 3.5.

An employee's salary,

S

(

n

)

, in dollars, at a company is a function of the number of years,

n

, that the employee has worked at the company.

The relationship between

n

and

S

(

n

)

is shown in the table below.

The question is incomplete. Here is the complete question.

An employee's salary, S(n), in dollars, at a company is a function of the number of years, n, that the employee has worked at the company.

The relationship between *n *and *S(n) *is shown in the table below.

Which** **of the following** **equations represents an explicit formula for *S(n)*?

A. S(n) = 40,000(1.05)ⁿ

B. S(n) = 40,000 + 1.05n

C. S(n) = 40,000(1.05)ⁿ⁻¹

D. S(n) = 40,000 + 1.05(n-1)

**Answer:** A. S(n) = 40,000(1.05)ⁿ

**Step-by-step explanation:** The table shows an exponential function, which is, in general, is of the form:

[tex]S(n)=S_{0}r^{n}[/tex]

where

S₀ is the initial value

r is the rate the salary grows

n is the years the employee worked

From the table, in the first year, an employee receives $40,000, so, that is the initial value.

The salary increases at a constant rate of 1.05 per year, as shown below:

[tex]r=\frac{42,000}{40,000}=\frac{44,100}{42,000}=\frac{46,305}{44,100}[/tex]

r = 1.05

So, the rate the salary grows is r = 1.05 or 5%.

**Therefore, the equation that shows an explicit formula for S(n) is **[tex]S(n)=40,000(1.05)^{n}[/tex]**.**

What is the relative minimum of the function?

if anyone could help it would be appreciated!! :)

**Answer:**

-2

**Step-by-step explanation:**

since the parabola opens upwards, the minimum is at the vertex of the parabola and the maximum is infinity, because the lines of a parabola goes on forever

you look for the smallest x value for the parabola and since you can see that the vertex of the parabola lies on x=-2, the minimum value of the function is -2.

Hope that helps :)

The value of Adam's model railway is $550.

This value increases exponentially at a rate of r %

per year.

At the end of 5 years the value will be $736.

Calculate the value of r.

**Answer:(c)**

**Step-by-step explanation:**

Given

The initial value of Adam's model is [tex]A_o=\$550[/tex]

the value increases exponentially with the rate of [tex]r\%[/tex]

Time period [tex]t=5\ years[/tex]

Final amount [tex]A=\$736[/tex]

Exponential growth is given by

[tex]\Rightarrow A=A_o(1+r)^t[/tex]

Putting values

[tex]\Rightarrow 736=550(1+r)^5\\\\\Rightarrow (1+r)^5=1.338[/tex]

[tex]\Rightarrow 1+r=1.05999\\\Rightarrow r=0.05999\ or\ 5.99\%\approx 6\%[/tex]

Option (c) is correct

The temperature readings from a thermocouple in a furnace fluctuate according to a cumulative distribution function,

0, x < 800 oC

F(x) = 0.05x - 40, 800 oC< or is equal to x < 820 oC

1, x > 820 oC

Determine the following.

A) P(X< 810.0).

B) P(800
C) P(X> 808.40).

D) If the specifications for the process require that the furnace temperature be between 805.60 and 808.40oC, what is the probability that the furnace will operate outside of the specifications?

**Answer:**

[tex]P(x<810)=0.5[/tex]

[tex]P(x<800) = 0[/tex]

[tex]P(x>808.40) = 0.58[/tex]

[tex]P(x\le805.40\ or\ x\ge 808.40) = 0.85[/tex]

**Step-by-step explanation:**

**Given:**

[tex]F(x) = \left\{\begin{array}{ll}{0} &; {x<800^{\circ} \mathrm{C}} \\ {0.05 x-40} &; {800^{\circ} \mathrm{C} \leq x<820^{\circ} \mathrm{C}} \\ {1} &; {x>820^{\circ} \mathrm{C}}\end{array}[/tex]

**Solving (a): P(x < 810)**

To solve this, we make use of:

[tex]P(x<810) = F(x) = 0.05x - 40[/tex]

**Because**

[tex]800^\circ C \le 810 \le 820^\circ C[/tex]

**So:**

[tex]F(x) = 0.05 * 810 -40[/tex]

[tex]F(x) = 40.5 -40[/tex]

[tex]F(x) = 0.5[/tex]

**Hence:**

[tex]P(x<810)=0.5[/tex]

**Solving (b): P(x < 800)**

**To solve this, we make use of:**

[tex]P(x<800) = F(x) = x[/tex]

**Because:**

[tex]x < 800^\circ C[/tex]

**So:**

[tex]P(x<800) = 0[/tex]

**Solving (c): P(x > 808.40)**

Here, we make use of complement rule:

[tex]P(x>808.40) = 1 - P(x \le 808.40)[/tex]

Where:

[tex]P(x\le808.40) = 0.05x - 40[/tex]

[tex]P(x\le808.40) = 0.05*808.40 - 40[/tex]

[tex]P(x\le808.40) = 0.42[/tex]

So:

[tex]P(x>808.40) = 1 - 0.42[/tex]

[tex]P(x>808.40) = 0.58[/tex]

**Solving (d) The probability that the temperature lies outside 805.60 and 808.40**

**First, we calculate the probability that it lies within.**

**This is represented as:**

[tex]P(805.40 < x < 808.40)[/tex]

**This is calculated using:**

[tex]P(805.40 < x < 808.40) = F(808.40) - F(805.40)[/tex]

[tex]P(805.40 < x < 808.40) = 0.05*808.40-40 - (0.05*805.40-40)[/tex]

[tex]P(805.40 < x < 808.40) = 0.42 - (0.27)[/tex]

[tex]P(805.40 < x < 808.40) = 0.42 - 0.27[/tex]

[tex]P(805.40 < x < 808.40) = 0.15[/tex]

**Using complement rule, the required probability is:**

[tex]P(x\le805.40\ or\ x\ge 808.40) = 1 - 0.15[/tex]

[tex]P(x\le805.40\ or\ x\ge 808.40) = 0.85[/tex]
