Answer:

Step-by-step explanation:

The theoretical probability of an event is the number of favorable outcomes over the total number of possible outcomes. In this case, the total number of possible outcomes is 2, since each camper can either swim or hike. The number of favorable outcomes for swimming is also 2 (heads on a coin flip). Therefore, the theoretical probability of swimming is 2/2 or 1/2.

The experimental probability of an event is the number of times the event occurred in the experiment divided by the total number of trials. In this case, there were 12 students who chose to swim out of 40 total students. Therefore, the experimental probability of swimming is 12/40 or 3/10.

Comparing the two probabilities, we see that the theoretical probability of swimming is 1/2 while the experimental probability of swimming is 3/10. Therefore, the statement "The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40" is true.

The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40.

The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40. (option b)

The theoretical probability of an event is calculated based on the assumption of equal likelihood for all possible outcomes. In this case, since each student flips a fair coin, there are two equally likely outcomes: heads (swimming) and tails (hiking). Therefore, the theoretical probability of swimming (P(swimming)) is 1/2, and the theoretical probability of hiking is also 1/2.

However, the experimental probability is determined by the actual outcomes observed in the experiment. According to the data provided, out of the 40 students, 12 students got heads (swimming) and 28 students got tails (hiking). To find the experimental probability of swimming, we divide the number of students who swam by the total number of students:

12/40 = 0.3.

The theoretical probability of swimming, P(swimming), is one half (0.5), but the experimental probability is 28 over 40 (0.7).

The theoretical probability of swimming, P(swimming), is one half (0.5), but the experimental probability is 12 over 40 (0.3).

The theoretical probability of swimming, P(swimming), is 12 over 28 (~0.4286), but the experimental probability is one half (0.5).

The theoretical probability of swimming, P(swimming), is 28 over 40 (0.7), but the experimental probability is one half (0.5).

Out of these options, the correct one is the theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40. (option b).

29 + 14 = 44 by decomposing numbers to add and make a new 10.

Decomposition of numbers involves breaking a number down into its constituent parts or smaller numbers that add up to the original number. This can be done in different ways depending on the purpose and context of the problem.

For example, one common way of decomposing a number is by place value. In this case, the number is broken down into its digits, which represent different powers of ten. For instance, the number 562 can be decomposed into 500 + 60 + 2.

Another way of decomposing numbers is by factoring. In this case, the number is expressed as a product of its factors. For example, the number 12 can be decomposed as 2 x 2 x 3.

Decomposing numbers is a useful skill in many areas of mathematics, including arithmetic, algebra, and geometry. It is often used to simplify problems, make computations easier, and facilitate further analysis.

To decompose 29 to make a new 10, we can break it into 9 and 20. Then, to decompose 14 to make a new 10, we can break it into 6 and 8.

So, we have:

29 + 14 = (9 + 20) + (6 + 8)

Now, we can regroup the numbers to make a new 10:

= (9 + 1) + (20 + 6) + 8

= 10 + 26 + 8

= 44

Therefore, 29 + 14 = 44 by decomposing numbers to add and make a new 10.

What Mathematics

Step-by-step explanation:

We may conclude after answering the presented question that Therefore, the coordinates of point C are (-6, 0).

In mathematics, a coordinate is a number or combination of numbers that represents the location of a point or object in space. Coordinates are frequently used to define a point or object's position in a certain coordinate system, such as the Cartesian or polar coordinate systems. In the Cartesian coordinate system, a point is found by its distance from the origin along the x-axis and its distance from the origin along the y-axis. These distances are represented by two integers, the x-coordinate and the y-coordinate. The point's location in the plane is specified by the two coordinates.

Using the distance formula, we can find the distances AC and CB:

[tex]AC = \sqrt((x - (-8))^2 + (y - 4)^2)\\CB = \sqrt((10 - x)^2 + (-2 - y)^2)\\[/tex]

Since AC:CB = 2:1, we have:

[tex]AC/CB = 2/1\sqrt((x - (-8))^2 + (y - 4)^2) / \sqrt((10 - x)^2 + (-2 - y)^2) = 2/1\\(x - (-8))^2 + (y - 4)^2 / ((10 - x)^2 + (-2 - y)^2) = 4\\(x - (-8))^2 + (y - 4)^2 = 4((10 - x)^2 + (-2 - y)^2)\\5x^2 + 5y^2 - 116x + 20y + 340 = 0\\(x - (-8))^2 + (y - 4)^2 = r^2\\(x - (-8))^2 + (y - 4)^2 / ((10 - x)^2 + (-2 - y)^2) = 4\\[/tex]

where r is the radius of the circle.

Solving this system of equations, we get:

x = -6

y = 0

Answer:

  a1 = 1875

Step-by-step explanation:

You want a1 for the geometric series that has r = 2/5, an = 120, and Sn = 3045.

The n-th term of the geometric series with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

The sum of the first n terms of the geometric series is ...

  Sn = a1·(r^n -1)/(r -1)

We can use the expression for an to substitute for r^n in the sum equation:

  [tex]a_n=a_1(r^n)(r^{-1})\\\\r^n=\dfrac{a_n}{a_1r^{-1}}=\dfrac{a_nr}{a_1}\\\\S_n=a_1\dfrac{r_n-1}{r-1}=a1\dfrac{\dfrac{a_nr}{a_1}-1}{r-1}\\\\S_n=\dfrac{a_nr-a_1}{r-1}\\\\a_1=a_nr-S_n(r-1)=a_nr+(1-r)S_n\\\\a_1=(120)\dfrac{2}{5}+(1-\dfrac{2}{5})(3045)=\dfrac{2\cdot120+3\cdot3045}{5}\\\\\boxed{a_1=1875}[/tex]

__

Additional comment

The sum is of the first four terms:

  1875 +750 +300 +120 = 3045

We can also find this by working backward. The previous term is 5/2 times the current term. We need to find the terms that have a sum of 3045.

  120 +300 +750 +1875 +4687.5 +...

Clearly, 5 terms is too many. The sum of the first 4 terms of the backward series is 3045, so we know n=4 and the first term is 1875—the last term of our 4-term backward series.

The quadratic equation f(x) = x² + 2x - 12 can be rewritten as f(x) = (x + 1)²- 13 using the completing square method.

Completing the square is a strategy used in algebra to solve quadratic equations of the type ax² + bx + c = 0, where a, b, and c are constants and x is the variable. By converting the quadratic equation into a perfect square trinomial, the square roots of both sides of the equation may be used to quickly solve the problem. This is the core notion behind the completion of the square. The quadratic expression becomes a perfect square when we add and subtract a specific number from it to complete the square. Half of the x-term squared coefficient is equal to the sum of the numbers we add and remove.

The given function is f(x) = x² + 2x-12.

Now, group the x terms together:

f(x) = (x² + 2x) - 12

Between the parenthesis, add and remove the square of the x-half-coefficient: term's:

f(x) = (x² + 2x + (2/2)² - (2/2)²) - 12

f(x) = (x + 1)² - 1 - 12

First, we need to find the maximum height that the rocket will reach. To do that, we need to find the vertex of the parabolic function h(t) = -16t^2 + 144t + 9. We can use the formula for the vertex of a parabola, which is given by the formula t = -b/2a, where a = -16 and b = 144.

t = -b/2a = -144/(2*(-16)) = 4.5

So the rocket will reach its maximum height after 4.5 seconds.

To find the maximum height, we need to substitute t = 4.5 into the function h(t):

h(4.5) = -16(4.5)^2 + 144(4.5) + 9 = 324

So the maximum height that the rocket will reach is 324 feet.

Therefore, the rocket will reach its maximum height of 324 feet after 4.5 seconds.

We have the equation:

√2 - √36 - 2x = 6

Simplifying the radicals we get:

√2 - 6 - 2x = 6

Adding 6 to both sides we get:

√2 - 2x = 12

Subtracting √2 from both sides we get:

-2x = 12 - √2

Dividing by -2 we get:

x = (6 - (1/√2))

Therefore, the real solution is:

x = (6 - (1/√2))

To check for extraneous solutions, we need to substitute this value of x back into the original equation and check if it satisfies the equation.

√2 - √36 - 2(6 - (1/√2)) = 6

Simplifying this we get:

-6 = 6

This is not true, so the solution x = (6 - (1/√2)) is extraneous.

Therefore, there is no real solution to the equation.

If 8 cups of flour are mixed with 12 cups of sugar, then the ratio of flour to sugar is:

8 : 12

Simplifying this ratio by dividing both numbers by 4, we get:

This means that for every 2 cups of flour, we need 3 cups of sugar.

If we are using 27 cups of sugar, we can set up a proportion to find out how much flour we need:

2/3 = x/27

Multiplying both sides by 27:
