Answer: The expected probability that the coin will land with the tails side facing up the next time it is tossed can be calculated by taking the ratio of the number of times the tails side came up to the total number of tosses. In this case, the coin landed tails 12 times out of 30 tosses. So the probability of tails is:

12/30 = 0.4

Therefore, the expected probability that the coin will land with the tails side facing up the next time it is tossed is 0.4 or 40%.

It's important to notice that this probability is based on the assumption that the coin is fair, meaning it has an equal chance of landing heads or tails each time it is tossed.

The equation which is required to solve how many of each board John needs is x + x - 7 = 23.

The number of 20-foot boards is 15.

The number of 16-foot boards is 8.

As per the given data, John needs 23 boards to build rafters for his house.

He can use 16-foot or 20-foot length boards.

He needs seven fewer 16-foot boards than 20-foot boards.

Here we have to determine how many of each board John needs.

Let the number of 20-foot boards be x.

Then the number of 16-foot boards be x - 7.

Total number of boards are 23.

Equation to determine how many of each board John needs:

x + x - 7 = 23

2x - 7 = 23

2x = 23 + 7

2x = 30

x = 15

The number of 20-foot boards are 15.

The number of 16-foot boards are x - 7

= 15 - 7

As per the circumference of circle, the fencing cost altogether is $604.45

The term circumference in math is defined as the distance around a circle or any curved geometrical shape

Here we have know that a museum groundskeeper is creating a semicircular statuary garden with a diameter of 22 feet.

Here we have also know that there will be a fence around the garden and the fencing costs $8. 75 per linear foot.

Here we have the diameter then the value of radius is calculated as,

=> radius = 22/2 = 11

Then the circumference of the circle is calculated as,

=> C = 2 x π x 11

Apply the value of π as 3.14, then we get,

=> C = 2 x 3.14 x 11

=> C = 69.08

Then the cost for fencing is calculated as,

The solution of the system of equations:

is (-3, 6)

Here we want to solve the system of equations below:

y = -5x + 21

-4x + y = 6

We can use the elimination method to solve this if we take the difference between the two equations, we will get:

y - (-4x + y) = -5x - 21 - 6

4x = -5x - 27

Now we can solve this for x.

4x + 5x = -27

9x = -27

x = -27/9 = -3

And the value of y is given by:

y = -5x - 21  (we need to evaluate that on x = -3)

y = -5*-3 - 21

y =  15 - 21 = 6

The cubic equation 4 · x³ + 12 · x² + 3 · x - 5 = (2 · x - 1) · (p · x² + q · x + r) use the following coefficients: (p, q, r) = (2, 7, 5).

In this problem we find the definition of cubic equation as a product of a linear equation and a quadratic equation, the latter one has four unknown real coefficients, whose values can be found by expanding the product and comparing coefficients. First, write the entire equation:

4 · x³ + 12 · x² + 3 · x - 5 = (2 · x - 1) · (p · x² + q · x + r)

Second, expand the expression:

4 · x³ + 12 · x² + 3 · x - 5 = (2 · x - 1) · p · x² + (2 · x - 1) · q · x + (2 · x - 1) · r

4 · x³ + 12 · x² + 3 · x - 5 = 2 · p · x³ - p · x² + 2 · q · x² - q · x + 2 · r · x - r

4 · x³ + 12 · x² + 3 · x - 5 = 2 · p · x³ + (- p + 2 · q) · x² + (- q + 2 · r) · x - r

Third, find the values of p, q, r by comparison:

2 · p = 4

- p + 2 · q = 12

- q + 2 · r = 3

- r = - 5

Then:

p = 2, r = 5

q = - (3 - 2 · r)

q = - (3 - 2 · 5)

q = - (- 7)

q = 7

- 2 + 2 · 7 = 12

- 2 + 14 = 12

12 = 12

The values of real coefficients are (p, q, r) = (2, 7, 5).

If you pick any point and go up 100 and over 200, you get back on the line, so the slope is 100/200 or 1/2

Option C: C = 1/2 N + 400

Answer:

C. 1/2N +400

The total number of boys enrolled in the course is 170.

Here are 374 children, are there are 5 boys to every 6 girls.

If the ratio of boys to girls is 5 to 6, then 5 out of every 11 students are boys and 6 out of every 11 students are girls.

Set up a proportion for the boys, where b = the total number of boys.

5/11 = b/374

11b = 1870

b = 1870/11

b = 170

There are 170 boys.

The total number of student is 374, so the number of girls, is 374 -b.

There are 374-170= 204 girls.

Finding a proportionality constant would be another algebraic solution to this issue. The total number indicated by the ratio is 5 + 6 or 11, which is equal to the total number of children when multiplied by the proportionality constant.

The solution set for the given graph is (2,1). The solution has been obtained using linear equations.

What is a linear equation?

It is a linear equation that has the greatest degree of one. In a linear equation with an exponent greater than one, this indicates that there are no variables. A straight line is produced on the graph by this equation.

We are given two lines on the graph

The points of the red line are (3,0) and (0,3)

So, the equation of the line comes out to be

y=−x+3      ...(1)

The points of the blue line are (3,2) and (-1,-2)

So, the equation of the line comes out to be

y=x−1     ...(2)

To find the solution set, we need to solve the equations

Substituting (1) in (2), we get,

⇒−x+3 = x−1

⇒−2x = -4

⇒x = 2

So, y = 1

Answer:

? is 59 degrees

Step-by-step explanation:

the two angles created by the intersecting lines are vertical angles and are equal

also, we know there are a total of 180 degrees in a triangle, so

180 - (21 + 49) = 100

this will help us find '?' because we can add 21 and 100, to get 121, then deduct 121 from 180 to get the value of ? which is 59

The point at which the triangle's three interior angle bisectors intersect appears to be the incenter.

The incenter of a triangle seems to be the point at which the triangle's three interior angle bisectors intersect. This point is equidistant from the triangle's sides.

∠ARU angle = 40°

AU length = 20°

∠QPA = 35°

A diagram is included here.

AR is the angle bisector of angle URK.

As a result, ∠ARU = ∠ARK = 40°.

Because the incenter point is equidistant from the triangle's sides.

As a result, AT = AU = AK = 20.

Because PA is the angle bisector of angle QPU.

As a result, ∠QPA = ∠UPA.

3x + 2 = 4x - 9

4x - 3x = 9 + 2

x = 11

Changing the value of x in the angle 3x + 2

We obtain ∠QPA = 3(11) + 2 = 35°.
