There are 11 trees that are more than 6m tall but not more than 12m tall.
What is the Range?
In mathematics, a range is the set of all output values, or results, of a function. In statistics, a range is a measure of dispersion, which is used to describe the distribution of a set of data.
The table provided gives the frequency of trees at different height ranges. The range for the trees more than 6m tall but not more than 12m tall is 6<h<=9, and the frequency for this range is 11. This means that there are 11 trees in the park that are taller than 6 meters but not taller than 12 meters.
Hence, There are 11 trees that are more than 6m tall but not more than 12m tall.

What are the coordinates of the vertex of the graph of the function y 3x² 12x 3?.
Answers
The coordinates of the vertex of the function y = -3x² -12x + 3 is (-2,15) and the graph of the function is attached below.
Vertex in math is known as a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet.
Here we have given that the function y = -3x² - 12x + 3 and we have to find the coordinates of the vertex.
As we all know that for any equation of the type y = ax² + bx + c the vertex is given by (h, k)
And the value of the vertex is calculated by using the formula h = -b/2a and k = (4ac - b2)/4a.
From the given question we have identified the value of a = -3, b = -12 and c = 3
Then the value of h is calculated as,
=> h = -(-12)/2(-3)
When we simplify this one then we get the value of h as -2
Similarly the value of k is calculated as,
=> 4ac = 4(-3)(3) = -36
Then the equation is written as,
=> k = [-36 - (-12)2]/4(-3)
When we simplify this one then we get
=> k = -180/-12
Therefore, the value of k is 15
Hence the coordinates of the vertex is (h, k) = (-2, 15).

How many solutions does the following pair of linear equations have 3x 5y 20 6x 10y 40?.
Answers
The pair of linear equations 3x + 5y = 20 and 6x + 10y = 40 have infinitely many solutions.
The given pair of linear equations can be represented in the form of Ax + By = C and Dx + Ey = F, where A = 3, B = 5, C = 20, D = 6, E = 10, and F = 40.
To find the number of solutions for the given pair of linear equations, we can use the following method:
Form the determinant of the coefficients of the variables (x and y) by taking the product of A and E and subtracting the product of B and D.Calculate the value of the determinant, in this case (3 * 10) - (5 * 6) = 30 - 30 = 0. If the determinant is zero, the system has either no solution or infinitely many solutions. In this case, the system of equations has infinitely many solutions, since the determinant is zero.So, the pair of linear equations 3x + 5y = 20 and 6x + 10y = 40 have infinitely many solutions.

A toy american eskimo dog has a mean weight of 8 pounds with a standard deviation of 1 pound. Assuming the weights of toy eskimo dogs are normally distributed, what range of weights would 95% of the dogs have?.
Answers
95% of toy eskimo dogs have weight between 6.04 and 9.96 pounds assuming normal distribution.
What is weight ?
Weight is a measure of the force exerted on an object due to gravity. It is typically measured in units of mass such as kilograms (kg) or pounds (lbs). The weight of an object can be determined by multiplying its mass by the acceleration due to gravity.
Assuming the weights of toy eskimo dogs are normally distributed, we can use the standard normal distribution table to find the range of weights that would include 95% of the dogs.
The standard normal distribution table gives the proportion of data within a given number of standard deviations from the mean. Since the standard deviation of the toy eskimo dog's weight is 1 pound, we can use this table to find the range of weights that are within 1.96 standard deviations from the mean.
Using this method, we can find that 95% of the toy eskimo dogs will have a weight that is between 6.04 pounds (8 - 1.96) and 9.96 pounds (8 + 1.96).
95% of toy eskimo dogs have weight between 6.04 and 9.96 pounds assuming normal distribution.

A tiling pattern i defined by the pattern rule equation n=53pn=53p, where pp i the poition number and nn i the number of tile. How many tile would there be in poition 26?
Answers
Thus, position 26 would have 1378 tiles.
Pattern rule equation:
A pattern rule equation is a mathematical formula that describes how a pattern is created. It defines the relationship between the position number (p) and the number of tiles (n) in the pattern.
The pattern rule equation is a useful tool to predict the number of tiles in a certain position, for example, position 26 as I mentioned in my previous answer.
It's also useful to predict the total number of tiles in a pattern or to identify the position number of a specific number of tiles.
In the pattern rule equation n = 53p, n is the number of tiles and p is the position number. To find the number of tiles in position 26, we can substitute 26 for p in the equation:
n = 53p
n = 53(26)
n = 1378
So there would be 1378 tiles in position 26.

Quadratic Formula: The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.
The value b² - 4ac is called the discriminant of a quadratic equation and is represented as 'D'. The nature of the roots of the quadratic equation can be predicted based on the discriminant value.
If D > 0, the roots are real and distinct (two real solutions).
If D = 0, the roots are real and equal (one real solution).

When you solve an equation for one variable and then substitute the resulting expression in for that variable in the other equation its is known as Substitution method.
I will demonstrate how the substitution method works. Suppose we have the following systems of linear equations with two variables:
Equation 1: 3x + 2y = 11
Equation 2: -x + y = 3
By solving these two equations we get x=1 and y=4.
Equation 2: -x + y = 3
-x + x + y = x + 3
y = x + 3
Next, substitute the value of y in Equation 2 (from the previous step), and substitute its value into Equation 1 to solve for x:
Equation 1: 3x + 2y = 11
Substitute y = x + 3 into Equation 1:
3x + 2(x + 3) = 11
3x + 2x + 6 = 11
Combine like terms:
5x + 6 = 11
5x + 6 - 6 = 11 - 6
5x = 5
Divide both sides by 5 to solve for x:

Each ticket cost 54$.
$332 (the total cost of the tickets) less $5 (the service charge) equals the cost of 9 tickets.
Round your estimate to the nearest even number: If you want it to be an even $100, deduct $4 rather than $5. Then multiply by a whole number to get 9 + 2 = 10. You now have simple numbers. $10 is equivalent to $100 divided by 10 tickets.

In the context of the problem, the rate at which the automated car wash can wash cars is the number of cars that it can wash per unit of time.
The rate at which the automated car wash can wash cars is 30 cars per 5 hours. To find out how long it would take to wash 120 cars, we can use the formula:
Time = (Number of cars / Rate)
Time = (120 cars / 30 cars per 5 hours)
