When Mandy tossed a fistful of silver coins into the air, then picked up the 23 coins that landed heads up, this isn't a random sample of the coins.

In statistics, a simple random sample is a subset of individuals chosen at random from a larger set, with all individuals having the same probability. It is the process of selecting a sample at random.

A simple random sample is a subset of a population chosen at random. This sampling method gives each member of the population an exact equal chance of being chosen, reducing the risk of selection bias.

In this case, Mandy only picked heads, this isn't a random sample since it's biased.

The greatest common factor (GCF) of two or more numbers is the largest number that divides evenly into each of the numbers without leaving a remainder. To find the GCF of 24, 30 and 50, we can use the prime factorization method. The prime factorization of 24 is 2^3 * 3^1, the prime factorization of 30 is 2 * 3^1 * 5^1, and the prime factorization of 50 is 2 * 5^2. We can see that the GCF of these numbers is 2 * 3^1 = 6, since 6 is the highest power of 2 and 3 that divides all three numbers evenly. So, the GCF of 24, 30 and 50 is 6.

The radius of the circle is 15.7 mm.

The route or boundary that encircles any shape in mathematics is defined by the shape's circumference.

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle.

We have,

The circumference of Circle = 2πr

Also, The circumference of a circle is 98.596 millimeters.

So, circumference of Circle = 2πr

98.596 = 2πr

98.596 = 6.28r

r= 98. 596 / 6.28

r = 15.7 mm

Answer:

x > 4 / 5

Step-by-step explanation:

This is similar to solving 7x = 2x + 4, but instead you have an inequality. The only thing you have to watch out for is if you divide by a negative number, if you do, you have to flip the "alligator" sign.

To solve without having to flip:

\(7x > 2x + 4\\7x - 2x > 2x - 2x + 4\\5x > 4\\5x/5 > 4 / 5\\x > \frac{4}{5}\)

Solving requiring "alligator" flip:

\(7x > 2x + 4\\7x - 7x > 2x - 7x + 4\\0 > -5x + 4\\-4 > -5x\\\frac{-4}{-5} > \frac{-5x}{-5} \\ \frac{4}{5} < x\)

The angle 1 is 19 degrees and angle 2 is 379 degrees. The angles can be found by solving the equation cos(3x + 10) = sin(3x + 26). The two angles, angle 1 and angle 2, can be determined by finding the values of x that satisfy the equation.

To find the angles, we'll solve the equation cos(3x + 10) = sin(3x + 26) for x, taking into account that angles are in degrees.

First, we'll rewrite the equation using the trigonometric identity cos(theta) = sin(90 - theta):

cos(3x + 10) = cos(90 - (3x + 26))

For the angles to be equal, the expressions inside the cosine functions must be equal:

3x + 10 = 90 - (3x + 26)

Simplifying the equation:

3x + 10 = 90 - 3x - 26

Combine like terms:

6x = 54 - 10 - 26

6x = 18

Divide both sides by 6:

x = 3

Now that we have the value of x, we can find the corresponding angles.

Angle 1:

Plugging in x = 3 into the equation:

3x + 10 = 3(3) + 10 = 19

Therefore, angle 1 is 19 degrees.

Angle 2:

To find the second angle, we can use the fact that cosine is a periodic function with a period of 360 degrees. Adding 360 to angle 1 gives us:

19 + 360 = 379

Therefore, angle 2 is 379 degrees.

In summary, angle 1 is 19 degrees and angle 2 is 379 degrees.

Answer:

x = 46°

Step-by-step explanation:

Angles on a straight line sum to 180°.

Therefore, the interior angle of the triangle that forms a linear pair with the exterior angle marked 130° is:

⇒ 180° - 130° = 50°

The interior angle of the triangle that forms a linear pair with the exterior angle marked 96° is:

⇒ 180° - 96° = 84°

The interior angles of a triangle sum to 180°. Therefore:

⇒ 50° + 84° + x = 180°

⇒ 134° + x = 180°

⇒ 134° + x - 134° = 180° - 134°

⇒ x = 46°

Therefore, the size of angle x is 46°.

The first part of the trip took approximately 6.39 hours and the second part of the trip took approximately 5.84 hours.

In this problem, we are given the distance, total time, and average speeds for two parts of a plane trip.

Using the formula for average speed

Distance = average speed x time,

We can set up two equations and solve for the times spent flying at each speed.

We define t₁ as the time spent flying at 115 mph and t₂ as the time spent flying at 125 mph.

From the equation

730 miles = 115 mph x t₁,

we solve for t₁ and get

t₁ = 6.391304347826087 hours.

Similarly, from the equation

730 miles = 125 mph x t₂,

we solve for t₂ and get

t₂ = 5.84 hours.

Therefore, the plane flew at an average speed of 115 mph for approximately 6.39 hours and at an average speed of 125 mph for approximately 5.84 hours.

To describe a linear program for finding the largest axis-aligned square that lies entirely inside a polygon (p), we can define the decision variables, objective function, and constraints as follows:

Decision Variables:

Let x be the side length of the square.

Objective Function:

Maximize x. The objective is to find the largest possible side length for the square.

Constraints:

Square Within Polygon Constraint:

For each vertex (xᵢ, yᵢ) of the polygon p, we can define the following set of inequalities:

xᵢ ≤ x, for all vertices of the polygon.

These inequalities ensure that the square lies entirely within the polygon.

Square Symmetry Constraint:

To ensure that the square is axis-aligned, we can impose symmetry constraints. For example, if the coordinates of the center of the square are (c_x, c_y), then we can add the following constraints:

c_x ± (x/2) = constant, for fixed values of c_x.

c_y ± (x/2) = constant, for fixed values of c_y.

These constraints ensure that the sides of the square are parallel to the x and y axes.

Non-Negative Constraint:

x ≥ 0, to ensure a non-negative side length for the square.

By formulating and solving this linear program, we can find the optimal value for x, which represents the largest axis-aligned square that lies entirely within the given polygon p.

Cl is the confidence interval, x is the sample mean, σ is the population standard deviation, n is the sample size, and zα/2 is the z-score corresponding to the desired level of confidence.

The σ are fixed for a given level of confidence, we can achieve this by increasing n by a factor of 4.

Specifically, if we increase the sample size from n to 4n, then the new confidence interval will have half the width of the original interval.

Using the given function, it is found that it will take 38.12 years for the tree's height to exceed 17 feet.

The function that models the tree's height after t years is given by:

\(h(t) = 6 + 3\ln{(t + 1)}\)

It will be of 17 feet when h(t) = 17, hence:

\(h(t) = 6 + 3\ln{(t + 1)}\)

\(17 = 6 + 3\ln{(t + 1)}\)

\(3\ln{(t + 1)} = 11\)

\(\ln{(t + 1)} = \frac{11}{3}\)

\(e^{\ln{(t + 1)}} = e^{\frac{11}{3}}\)

\(t + 1 = e^{\frac{11}{3}}\)

\(t = e^{\frac{11}{3}} - 1\)

t = 38.12.
