The equation of the parabola is y = -2x² + 9x + 5.

To find the quadratic function that includes the set of values given, we need to solve for the coefficients of the quadratic equation in the standard form of y = ax² + bx + c, where a, b, and c are constants.

Substituting the values of the points (0, 5), (2, 15), and (4, 9) into the quadratic equation, we get a system of three equations:

For (0, 5):

5 = a(0)² + b(0) + c

5 = c

For (2, 15):

15 = a(2)² + b(2) + c

15 = 4a + 2b + 5

For (4, 9):

9 = a(4)² + b(4) + c

9 = 16a + 4b + 5

Now, we can solve the system of equations for a and b:

4a + 2b = 10

16a + 4b = 4

Multiplying the first equation by 2 and subtracting it from the second equation, we get:

16a + 4b - 8a - 4b = 4 - 20

8a = -16

a = -2

Substituting a = -2 into the first equation, we get:

4(-2) + 2b = 10

2b = 18

b = 9

Therefore, the quadratic function that includes the set of values (0, 5), (2, 15), and (4, 9) is:

y = -2x² + 9x + 5

Step-by-step explanation:

The ratio of Mary's share to Katherine's share to Alex's share is 5:4:1, which means Mary pays 5/10 of the bill, Katherine pays 4/10 of the bill, and Alex pays 1/10 of the bill.

To find the ratio, we can write their contribution as a fraction of the total parts and then solve the fractions then they'll have the same denominator.

So, Mary's share is 5/10, Katherine's share is 4/10, and Alex's share is 1/10.

To convert this as a ratio, we write 5:4:1, where each number represents the number of parts each person pays, and the colon separates each person's contribution.

Therefore, the ratio of Mary's share to Katherine's share to Alex's share is 5:4:1

28.8%​ is the probability that a data value is between 48 and 52.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

First, we need to standardize the values and use a standard normal distribution table or calculator.

The standardized value of 48 is:

z = (48 - 48) / 5 = 0

The standardized value of 52 is:

z = (52 - 48) / 5 = 0.8

Now we need to find the probability that a data value is between z = 0 and z = 0.8 in a standard normal distribution. We can use a standard normal distribution table or calculator to find this probability.

Using the table or calculator, we can find that the probability of a data value being between z = 0 and z = 0.8 in a standard normal distribution is approximately 0.2881.

Rounding this answer to the nearest tenth of a percent, we get:

P(48 < x < 52) ≈ 28.8%

Therefore, the answer is D, 28.8%.

Unconscious processing is a complex cognitive phenomenon that involves a wide range of mental activities that occur outside of our conscious awareness. It is not simply a group of answer choices or a set of predetermined responses that are guided by habit or well-established routines.

Rather, unconscious processing is a highly nuanced and multifaceted process that is guided by a variety of different factors, including our emotions, our past experiences, our cultural background, and our personal beliefs and values.

At the same time, it is important to note that unconscious processing is not entirely independent of our executive functions or our conscious awareness. While it may be composed of relatively specialized parts, such as our automatic reflexes and basic sensory processing systems, these parts are still intricately connected to the higher-level cognitive processes that govern our decision-making, problem-solving, and goal-oriented behavior.

In short, unconscious processing is a complex and dynamic process that involves a broad range of cognitive and emotional factors, and is intimately intertwined with our conscious awareness and executive functions.

Answer:

1/32

Step-by-step explanation:

We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.

1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32

Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.

The Value for s/t is 4/5.

We know that the general equation for a circle is ( x - h )² + ( y - k )² = r², where ( h, k ) is the center and r is the radius.

Given:

x² + y² + sx + ty + 33 = 0

x² + y² + sx + s²x²/4 + ty + t²y² / 4 + 33 = 0

(x² + + sx + s²x²/4) + (y² + ty + t²y²/4 ) + 33 = 0

(x+ sx/2)² + ( y+ ty/2)² + 33 = 0..............(1)

We know that the standard form

(x-a)² + (y- b)² = r²

where (a, b) is the center.

So, We have center (4,5)

(x-4)² + (y- 5)² = r²

Now Comparing above with Equation (1) we get

s/2 = -4 and t/2 = -5

s= -8 and t= -10

We have to determine the equation for the line between (4,5,6) and (1,0,-3) in R³. Equation is written as (x, y,z) = (4,5,6) + (1,0,-3). The midpoint is equals to middle point of a line segment. It is equidistant from both endpoints. The midpoint can be found with the formula, \((x, y, z) = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}, \frac{z_1 + z_2}{2})\)

Here (x₁, y₁ , z₁) and (x₂, y₂, z₂) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points. Here,

x₁ = 4, y₁ = 5, z₁ =6 and x₂ = 1, y₂=0, z₂ = -3, Substitute all known values in above formula, \((x, y, z) = (\frac{4+1}{2}, \frac{5+ 0}{2}, \frac{6+ (-3)}{2}). \)

Since probabilities cannot be negative, we can conclude that the given probabilities are inconsistent or there might be an error in the information provided. Please verify the values and provide correct probabilities so that we can accurately calculate P(B|A), the probability of the flight being delayed when it is raining.

Let's denote the events as follows:

A: It will rain

B: The flight will be delayed

We are given the following probabilities:

P(A) = 0.11 (probability of rain)

P(B) = 0.14 (probability of flight delay)

P(A'∩B') = 0.76 (probability of no rain and on-time departure)

We can use the probability formula to calculate the probability of the flight being delayed when it is raining, P(B|A), which is the probability of B given A.

We know that:

P(B|A) = P(A∩B) / P(A)

To find P(A∩B), we can use the formula:

P(A∩B) = P(A) - P(A'∩B')

Substituting the given values:

P(A∩B) = P(A) - P(A'∩B')

P(A∩B) = 0.11 - 0.76

P(A∩B) = -0.65

The correct solution to the inequality x^2 - 9x < -18 is x < 3 or x > 6.

To solve the inequality x^2 - 9x < -18, you can follow these steps:

Move all terms to one side of the inequality to form a quadratic expression: x^2 - 9x + 18 < 0.

Factorize the quadratic expression: (x - 6)(x - 3) < 0.

Determine the sign of the expression for different intervals of x. To do this, you can create a sign chart:

Interval | (x - 6) | (x - 3) | (x - 6)(x - 3) |

x < 3 | - | - | + |

3 < x < 6 | - | + | - |

x > 6 | + | + | + |

Analyze the sign chart to determine when the expression (x - 6)(x - 3) is less than zero (negative).

The expression is negative when x is between 3 and 6, i.e., 3 < x < 6.

Write the solution in interval notation:

x < 3 or x > 6

Therefore, the correct solution to the inequality x^2 - 9x < -18 is x < 3 or x > 6.

The domain of the function f(x) = 5x - 10 is the set of all real numbers.

If the range of the function f(x) = 5x - 10 is given by the set of all positive real numbers, we can determine the domain of the function based on this information.

The range of the function is the set of all possible output values (y-values) that the function can produce.

The range is specified as all positive real numbers.

To find the domain of the function, we need to consider the values of x for which the function is defined and produces valid outputs.

The function f(x) = 5x - 10 is a linear function, which means it is defined for all real numbers.

The domain of a linear function is unrestricted, meaning it includes all real numbers.

Cosine is:

Secant is:

or

Both refer to the same (adjacent) angle therefore cosine is used more often than secant.

Answer:

Step-by-step explanation:

In trigonometry, secant in a right triangle, is the reciprocal of the cosine of an angle symbol: sec while cosine is in a right triangle, is the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.

The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. The cosine of ∠A will be abbreviated as cos ∠A

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
