The probability that the actress will need to attend more than 5 try-outs is approximately 0.478.

Since the outcomes of each try-out are independent,

As per the given information,

Number of try-out is 0.15

probability means the possibilities.

We can model the number of try-outs needed to get an offer as a geometric random variable with the probability of success p = 0.15.

Let X be the number of tryouts needed to get an offer.

Then, X follows a geometric distribution with parameter p=0.15, and the probability of needing to attend more than 5 try-outs is:

[tex]P(X > 5) &= 1 - P(X \leq 5)[/tex]

=[tex]1 - \sum_{k=1}^{5} P(X=k)[/tex]

= 1 [tex]- \sum_{k=1}^{5} P(X=k)[/tex]

= [tex]1 - [(1-p)^0p + (1-p)^1p + (1-p)^2p + (1-p)^3p + (1-p)^4p][/tex]

=[tex]1 - [(1-p)^0p + (1-p)^1p + (1-p)^2p + (1-p)^3p + (1-p)^4p][/tex]

=  0.478

Hence the number of possibility required to attend more than 5 try-outs is approximately 0.478.

The radius of the circle is √17.

The center of the circle is (4, 2).

A circle is a two-dimensional figure with a radius and circumference of 2πr.

The area of a circle is πr².

We have,

The equation of a circle with radius r and center (h, k) is

(x - h)² + (y - k)² = r²

Now,

x² + y² - 4 y - 8x + 3 = 0

x² - 8x + y² - 4y + 3 = 0

x² - 8x + 4² - 4² + y² - 4y + 2² - 2² + 3 = 0

(x - 4)² + (y - 2)² - 16 - 4 + 3 = 0

(x - 4)² + (y - 2)² = 16 + 4 - 3

(x - 4)² + (y - 2)² = √17

This means,

radius = √17 and center = (4, 2)

Thus,

The radius and center of the circle are √17 and (4, 2).

Joan paid with $19.00, she should receive $19.00 - $12.00, which equals $11.30 in change.So Joan should receive 11.30 in change.

Joan should receive $11.30 in change. To calculate this, we must start with the total cost of her items, which comes to $10.20 ($1.20 for the milk, $4.70 for the sandwich, and $3.30 for the sherbet). To this we must add the tax, which was $1.80. This brings the total cost to $12.00. Joan should receive $11.30 in change. To get this answer, we can use the following formula: Change = Total Payment - (Cost of Items + Tax). In this case, the formula would look like this: Change = 19.00 - (1.20 + 4.70 + 3.30 + 1.80). After calculating, the answer is 11.30. So Joan should receive 11.30 in change.

Answer:

The equation of the line of symmetry of triangle ABC is:

Step-by-step explanation:

The line of symmetry of an isosceles triangle bisects the vertex angle (the angle opposite the base) and is perpendicular to the base of the triangle.

As AB = AC, then angle A is the vertex angle of the isosceles triangle ABC.

If B and C lie on the line with equation 3y = 2x + 12, then the line of symmetry is the line that is perpendicular to this line and passes through A (4, 37).

Rearrange the given equation 3y = 2x + 12 to slope-intercept form by dividing both sides by 3:

[tex]\implies y=\dfrac{2}{3}x+4[/tex]

Perpendicular lines have slopes that are negative reciprocals of one another.  Therefore, the slope of the perpendicular line is -³/₂.

Substitute the found slope and point A (4, 37) into the point-slope formula:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-37=-\dfrac{3}{2}(x-4)[/tex]

Rearrange the equation to standard form:

[tex]\implies 2y-74=-3(x-4)[/tex]

[tex]\implies 2y-74=-3x+12[/tex]

[tex]\implies 3x+2y-74=12[/tex]

[tex]\implies 3x+2y=86[/tex]

Therefore, the equation of the line of symmetry of triangle ABC is:

The required measure of angle m∠Q is 42 degrees, as of the given condition.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should equal to 180°

Here,
In a triangle, the sum of the angles is always equal to 180 degrees. Therefore, for triangle OPQ,

m∠O + m∠P + m∠Q = 180°

Using the given information,

m∠O = (6x - 14)°

m∠P = (2x + 16)°

m∠Q = (2x + 8)°

(6x - 14)° + (2x + 16)° + (2x + 8)° = 180°

10x + 10 = 180°

10x = 170

x = 17

Substituting the value of x back into the expression for m∠Q,

m∠Q = (2x + 8)°

m∠Q = (2 * 17 + 8)°

m∠Q = 42°

So the value of m∠Q is 42 degrees.

When the outside temperature is 30°F, the sales is $414.13

When the sale is $1,993.33, the outside temperature is 78°F

Since the equation y = 32.9x - 572.87 can be used to model the relationship between sales at a local ice cream shop, y, in dollars, and the outside temperature, x, in degrees Fahrenheit (F).

Thus, when the outside temperature is 30°F, the sales can be estimated by substituting x = 30°F into the equation and solving for y. That is:

y = 32.9x - 572.87

y =  32.9(30) - 572.87

y = 987 - 572.87

y = $414.13

Thus, when the sale is $1,993.33, the outside temperature can be estimated by substituting y = $1,993.33 into the equation and solving for x. That is:

y = 32.9x - 572.87

1,993.33 = 32.9x - 572.87

32.9x = 1,993.33 + 572.87

32.9x = 2566.2

The system of equations 5x+2y=-7 and 10x+4y= -14 has unique solution which is (-7/5,0).

In general, a system of linear equations can have one of three possible outcomes:

One unique solution (as in this case)

No solution (if the equations are inconsistent)

Infinitely many solutions (if the equations are dependent)

To solve this system of equations, we can use the method of elimination or substitution. Let's use the method of elimination, which involves adding or subtracting the equations to eliminate one variable.

First, we need to choose a variable to eliminate. Looking at the coefficients of x and y, we see that we can eliminate y by multiplying the first equation by -2 and adding it to the second equation:

-10x - 4y = 14

5x + 2y = -7

-5x = 7

Now we can solve for x:

-5x = 7

x = -7/5

We can substitute this value of x into one of the equations to solve for y. Let's use the first equation:

5x + 2y = -7

5(-7/5) + 2y = -7

-7 + 2y = -7

2y = 0

y = 0

Therefore, the solution to the system of equations is (x,y) = (-7/5,0).

This is called a unique solution, meaning there is only one possible solution for the system of equations.

The standard function for F(x)=4(x+6)2+5, will be f(x)=8x+53.

What is the definition of a function?

A function is defined as a connection between a set of inputs and a single output. A function is a link between inputs that corresponds to exactly one output. Every function has a domain, a co-domain, and a range. A function is often denoted as f(x), where x represents the input. The general representation of a function is y = f(x).

There are several types of functions in mathematics. Here are a few examples:

An injective function or a one to one function exists when there is a mapping for a range for each domain between two sets.

Surjective functions, also known as Onto functions, are employed for transferring more than one element from domain to range.

A polynomial function is a function composed of polynomials.

Functions that may be used to inverse another function are known as inverse functions.

Now,

Given function is F(x)=4(x+6)2+5

The current age of Rita is 17 years and Cheryl is 7 years respectively, according to mentioned data.

Let us assume Rita's present age be x and Cheryl's age be y.

Rita's age two years ago = 3 × Cheryl's age two years ago

x - 2 = 3 (y - 2) - equation 1

Rita's age after three years = 3 × Cheryl's age after three years

x + 3 = 2 (y + 3) - equation 2

Solving equation 1

x - 2 = 3y - 6

x = 3y - 6 + 2

x = 3y - 4

Solving equation 2

x + 3 = 2y + 6

x = 2y + 6 - 3

x = 2y + 3

Keep the value of x from equation 2 in equation 1

2y + 3 = 3y - 4

Rearranging the equation

3y - 2y = 3 + 4

y = 7

Keep the value of y in equation x = 2y + 3

x = 2×7 + 3

x = 14 + 3

x = 17

So, Cheryl's and Rita's age is 7 and 17 years respectively.

Answer:

y = (2/3)x + 3

Step-by-step explanation:

first we need to find the y-intercept

we can do this by using what is given, the point (-3,1) and the slope (2/3)

using the slope-intercept formula: y = mx + b.

m = slope

b = y intercept

we can plug in the x and y values we were given

so,

1 = (2/3)(-3) + b

we can now easily solve for b

1 = (2/3)(-3) = b

first multiply

1 = -2 + b

then add 2 to both sides, this way we isolate b

3 = b

now that we have the y intercept we can write the equation of the line

y = (2/3)x + 3

if you really wanted to, you can check if this is correct by plugging in the point again and seeing if the equation is true.

1 = (2/3)(-3) + 3

multiply first

1 = -2 + 3

add the like terms

1 = 1
