The probability that at least 4 buyers would prefer green among the 16 selected is approximately 0.1031.

What is probability?

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.

This problem can be modeled as a binomial distribution with n = 16 trials and p = 0.3 probability of success (preferring green).

Let X be the number of buyers who prefer green among the 16 selected. We need to find P(X ≥ 4).

Using a binomial probability table or calculator, we can find:

P(X ≥ 4) = 1 - P(X < 4)

= 1 - P(X ≤ 3)

= 1 - [P(X=0) + P(X=1) + P(X=2) + P(X=3)]

= 1 - [0.1233 + 0.2854 + 0.3028 + 0.1854]

= 0.1031 (rounded to 4 decimal places)

Therefore, the probability that at least 4 buyers would prefer green among the 16 selected is approximately 0.1031.

Answer: Gloria must but at least one ticket in order for the first plan to be the better plan

What are linear and non-linear functions?

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

The point that partitions segment AB in a 1:4 ratio is (-1, -0.4).

In this scenario, line ratio would be used to determine the coordinates of the point Q on the directed line segment AB that partitions the segment into a ratio of 1 to 4.

In Mathematics, line ratio can be used to determine the coordinates of Q and this is modeled by the following mathematical expression:

Q(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Substituting the given parameters into the line ratio formula, we have;

Q(x, y) = [(1(7) + 4(-3))/(1 + 4)],  [(1(-10) + 4(2))/(1 + 4)]

Q(x, y) = [(7 - 12)/(5)],  [(-10 + 8)/5]

Q(x, y) = [-5/5],  [(-2)/(5)]

Q(x, y) = [-1, -2/5]

The probability that exactly 7 employees out of 23 sent complete the program is 0.217 or 21.7%.

In this case, the number of trials is 23, and the probability of success is 0.4 (since, on average, 40% of those sent complete the program). We want to find the probability of exactly 7 successes.

The binomial probability formula is:

P(X=k) = [tex](^n_k) \times p^k \times (1-p)^{(n-k)}[/tex]

Where P(X=k) is the probability of k successes, n is the total number of trials, p is the probability of success, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.

Using this formula, we can calculate the probability of exactly 7 employees completing the program as follows:

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to solve problems related to geometry, physics, engineering, and many other fields. Trigonometry is based on the study of the six trigonometric functions: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). These functions describe the ratios of the lengths of the sides of a right triangle, and can be used to calculate the unknown side lengths or angles of a triangle. Trigonometry is also useful for working with periodic functions, such as waves and oscillations. The trigonometric functions can be used to model and analyze these periodic phenomena, and to predict future behavior based on past observations. Applications of trigonometry can be found in many areas of science, engineering, and technology, including astronomy, navigation, architecture, surveying, and electronics.

Here,

To find sin(A), we need to use the trigonometric ratios of the sides of the right triangle ABC, where angle A is opposite to side a, angle B is opposite to side b and angle C is opposite to side c. We have sides of the triangle as follows:

a = 72

b = 65

c = 97

To find sin(A), we can use the following formula:

sin(A) = opposite/hypotenuse

In this case, the opposite side of angle A is b and the hypotenuse is c, so we have:

sin(A) = b/c

sin(A) = 65/97

If a multiplies an n x p matrix b then the total number of multiplications involved is m x p. And is given by Dimensional vector.

For explanation, There are two separate cases to consider when multiplying an m-by-n matrix and an n-dimensional vector, or an m-by-n matrix and an n-by-p matrix.

When an m-by-n matrix, A, multiplies an n-dimensional vector, x, the number of separate multiplications involved is m. This is because in order to compute the dot product of A and x, each row of A needs to be multiplied by the vector x, resulting in m separate multiplications.

On the other hand, when A multiplies an n-by-p matrix, B, the number of separate multiplications involved is m x p. This is because in order to multiply A and B, each row of A must be multiplied by each column of B, resulting in m x p separate multiplications.

Therefore, the number of separate multiplications involved when multiplying an m-by-n matrix and an n-dimensional vector is m, and the number of separate multiplications involved when multiplying an m x n matrix and an n x p matrix is m x p.

The value of y when x = 25 is 30

What are direct variations ?

One quantity directly changes in response to a change in another quantity, which is referred to as direct variation. This suggests that if one quantity increases, the other will follow suit and rise in proportion. In a similar manner, if one quantity declines, the other amount also declines.

given y is directly proportional to x then the equation connecting them is

y = kx ← k is the constant of proportionality

To find k use the condition y = 36 when x = 30

So, 36=k(30)

=> k = 36/30 = 1.2

equation of proportionality:

y=1.2x

Answer:

Step-by-step explanation:

Let's use algebra to solve this problem.

Let's start by assigning variables to the unknown quantities. Let G be the initial number of green beads and Y be the initial number of yellow beads.

We know that the number of green beads is 1/3 the number of yellow beads:

G = (1/3)Y

After giving away some beads, he had 42 green beads and 270 yellow beads left. So we can set up two equations using this information:

G - 2f = 42

Y - 3f = 270

where f is the number of friends he gave the beads to.

Now we can substitute G = (1/3)Y into the first equation:

(1/3)Y - 2f = 42

Multiplying both sides by 3, we get:

Y - 6f = 126

Now we have two equations that we can solve simultaneously:

Y - 3f = 270

Y - 6f = 126

Subtracting the first equation from the second, we get:

3f = 144

So f = 48. He gave the beads to 48 friends.

To find the total number of beads he had at first, we can use the equation G = (1/3)Y:

G + Y = (4/3)Y = (4/3)(270) = 360

So he had a total of 360 beads at first.

Answer:

To solve the problem, we need to first determine the value of the quarters Anna has. Since there are 5 quarters, we have:

5 quarters = 5 x $0.25 = $1.25

Thus, Anna has $2.00 - $1.25 = $0.75 left. We can find the maximum number of dimes she can have by dividing this amount by the value of a dime, which is $0.10. Therefore:

$0.75 ÷ $0.10 = 7.5

Since Anna cannot have a fraction of a dime, we round down to the nearest whole number to get a maximum of 7 dimes. Therefore, the answer is option B, 5.

The correct option is the second one, your supervisor did not divide by the total number of bags.

Here we can see a table with the size of each bag (in grams) and the number of sold bags.

Now, remember that for a set of N numbers {x₁, ..., xₙ} the mean is:

M = (x₁ + x₂ + ...)/N

So the denominator is the amount of elements in the set.

Then here in the denominator we should see the total number of bags sold, which is:

25 + 32 + 40 + 18 = 115

That number should be in the denominator instead of the sum of the masses.

Then the correct option is the second one.

Next, we can do some easy multiplication such as the following:

3 x 4 = ?

? = 12.

Thus, the answer to your problem is, 12

Answer:

To find how much greater 4/5 is than 3/4 we can turn them into decimal values:

3/4 = 0.75

0.8 - 0.75 = 0.05

4/5 is 0.05 or 1/20 greater than 3/4

As a result, (x, y) = is the answer to a set of equations. (-17, -3). There aren't an endless number of answers because there is a single one.

The meaning of an equation in algebra is a mathematical assertion that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are split by the 'equal' symbol.

The statements that are true about this system of equations are:

The x-variable will be eliminated when adding the system of equations.

There are infinitely many solutions to the system of equations.

To eliminate the x-variable, we can add the two equations as follows:

(2x - 7y) + (-2x + 11y) = -13 + 1

Simplifying the left-hand side and the right-hand side gives:

4y = -12

Dividing both sides by 4 yields:

y = -3

Substituting y = -3 into either of the original equations gives:

2x - 7(-3) = -13

Simplifying this equation yields:

2x + 21 = -13

Subtracting 21 from both sides yields:

2x = -34

Dividing both sides by 2 yields:

x = -17

Therefore, the solution to the system of equations is (x, y) = (-17, -3). Since there is a unique solution, there are not infinitely many solutions.

The statement "The sum of the system of equations is 4y = -12" is false since the sum of the equations does not simplify to that expression.

The statement "x = 17" is false since the correct solution is x = -17.

The statement "The y-variable will be eliminated when adding the system of equations" is false since adding the equations only eliminated the x-variable.
