Answer: [tex]p + 254 \leq 471[/tex]
Step-by-step explanation:
The number of people in the theater plus 254 )the number of people already in the theater) must be less than or equal to the maximum amount allowed to be seated, 471.
So, [tex]p + 254[/tex] represents the number of people in the theater.
471 is the maximum amount of people.
So, p + 254 must be less than or equal to [tex]p + 254[/tex].
Therefore, we can say that:
[tex]p + 254 \leq 471[/tex]
Evaluate each expression.
The final answers are a) 12 b)3/28 c) 2

What is the sum of roots of x2 +5 x 6 0?
The sum of roots of x2 + 5x + 6 = 0 is -5.
x2 + 5x + 6 = 0
To find the sum of roots, we need to factor the equation :
x2 + 5x + 6 = 0
x2 + 3x + 2x + 6
= 0
x(x + 3) + 2(x + 3)
= 0
(x + 3)(x + 2) = 0
x = -3, -2
Sum of Roots = -3 + (-2) = -5
x2 + 5x + 6 = 0
To find the sum of roots, we need to factorize the given equation. To do that, we can divide the equation into two parts, x2 + 3x and 2x + 6. We can factorize the first part as x(x + 3) and the second part as 2(x + 3). Then, we can multiply both parts to get the factorized equation, (x + 3)(x + 2) = 0. We can solve this equation to get the roots, x = -3 and -2. Finally, we can add both roots to get the sum of roots, -3 + (-2) = -5.

how to determine sample size needed for confidence intercal when population standard deviation not known
When the population standard deviation is not known, the sample size needed for a confidence interval can be determined using the t-distribution.
The t-distribution is used to calculate the margin of error, which is the amount of variation that is allowed in the sample results. The sample size needed for a confidence interval is determined by calculating the critical value of the t-distribution for a given level of confidence and degree of freedom. The degree of freedom is the number of independent observations in the sample minus one.
The confidence level determines the critical value of the t-distribution, which is used to calculate the margin of error. The sample size is then calculated by dividing the margin of error by the desired confidence level. This method allows us to determine the sample size needed for a confidence interval even when the population standard deviation is unknown.

What is the relationship between the base and height when you are finding the area of a triangle?
The base in term of the height of the triangle is written as ;b = 2A/h.
Define the term area of a triangle?A closed triangle has three sides. It is among the fundamental geometric shapes because it has three vertices and three sides.
Based on the length of its sides, a triangle can be labeled as equilateral, isoscles, or scalene.A two-dimensional shape's area is the space the shape takes up. By dividing the shape equal unit squares and counting them, since each unit square takes up one square unit space, the area may be obtained.Think about the ABC scalene triangle. Keep in mind that the height of a triangle must be perpendicular towards the base in order for its area to be expressed as being half that of a rectangle. Create a perpendicular hence from a vertex to the opposite side.Thus, the formula for the are area of the triangle is -
A = 1/2 bh
In which,
b = base of the triangle.
h = height of the triangle.

Determine the equation, slope and y-intercept for a function
that outputs the total points the Dragons scored (p) based on
the number of 2-point baskets made (b).
Slope:
Y-Intercept:
Equation (in slope-intercept form):
Answer:
Slope: 2
Y-Intercept: 47
Equation (in slope-intercept form): p = 2b + 47.
Step-by-step explanation:
To determine the equation, slope, and y-intercept for a function that outputs the total points the Dragons scored based on the number of 2-point baskets made, you will need to use the information given about the number of 3-pointers, foul shots, and 2-point baskets made.
First, let's define p as the total number of points the Dragons scored and b as the number of 2-point baskets made.
We know that the Dragons scored a total of 12 three-pointers * 3 points per 3-pointer + 11 foul shots * 1 point per foul shot = 47 points from 3-pointers and foul shots.
Therefore, the total number of points the Dragons scored can be expressed as:
p = 47 points + 2 points per 2-point basket * b 2-point baskets
This equation is in slope-intercept form, with the slope being 2 points per 2-point basket and the y-intercept being 39 points.
The equation in slope-intercept form is:
p = 2b + 47
Therefore, the slope of the function is 2, the y-intercept is 39, and the equation is p = 2b + 47.

What are the 2 types of functions give examples?
The two types of functions are linear and non linear functions.
A linear function is a function that can be written in the form f(x) = mx + b, where m and b are constants. This type of function has a constant rate of change, meaning the output will always increase or decrease the same amount for a given change in the input. For example, if the input increases by 3, the output will increase by 6. An example of a linear function is f(x) = 3x + 5. This function will always increase by 3 for each increase in the input, and will always have a y-intercept of 5.
A non-linear function is a function that cannot be written in the form f(x) = mx + b. This type of function has a variable rate of change, meaning the output will increase and decrease at different rates for different changes in the input. An example of a non-linear function is f(x) = x2 - 4x + 5. This function will increase and decrease at different rates for different changes in the input, and will always have a y-intercept of 5.

Answer:
C, n= -1 or 1.
Step-by-step explanation: The bars around 3x+6 are absolute value bars (| |), meaning that whatever lies inside of them will turn positive. An example: |-9| ➡️ 9. So, since we do have the absolute value bars, multiplying 3 by -1 would not effect the equation. So therefor we could use a regular 1 or a negative one to make the equation equal to 9.

The discriminant of a quadratic equation is equal to the expression (b^2 - 4ac) where a, b, and c are the coefficients of the equation. In this case, the discriminant is equal to (5^2 - 4(2)(3)) = 25 - 24 = 1.
The discriminant of a quadratic equation is a numerical value that can be used to determine the nature of its roots. The discriminant is equal to the expression (b^2 - 4ac) where a, b, and c are the coefficients of the equation. In this case, the equation is 2x² 5x 3 0. We can identify the coefficients of the equation as a = 2, b = 5, and c = 3. Using the formula, the discriminant is equal to (5^2 - 4(2)(3)) = 25 - 24 = 1. This means that the equation has two real and equal roots, as the discriminant is equal to zero. This can be seen by factoring the equation, which gives us (2x - 3)(x + 1) = 0. The roots of the equation are then x = 3/2 and x = -1.
Discriminant = b^2 - 4ac

A triangle has two sides of length 8.3 and 3.4. What compound inequality describes the possible lengths for the third side, x?
Using Pythagoras theorem the compound inequality for the possible length is 7.6 ≤ x ≤ 9
Pythagoras TheoremPythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
To find the possible value for the third side, we have to use Pythagoras formula which is given as;
x² = y² + z²
In the first scenario, we would assume the third side is the hypothenuse
x² = 8.3² + 3.4²
x = 9
In the second scenario, we would assume the third side is one of the legs of the triangle and the formula will change to
8.3² = y² + 3.4²
y² = 8.3² - 3.4²
