Answer:

The answer is 0.039.

Step-by-step explanation:

The confidence interval narrows as the sample standard deviation gets smaller.

The width of a confidence interval depends on the sample size, the confidence level, and the sample standard deviation. The formula for a confidence interval is given as (sample mean - z-score * (sample standard deviation/square root of sample size)) to (sample mean + z-score * (sample standard deviation/square root of sample size)), where z-score depends on the confidence level.

Since the sample standard deviation is in the denominator of this formula, a smaller sample standard deviation results in a smaller value in the denominator and thus a narrower interval.

y = x is the linear regression equation for the given Dot plot.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, a graph of a linear regression that has points (60, 60) and (70, 70) as we can see in the graph.

From the general formula of the linear equation:

Y = mx + b

where m is the slope

b is the y-intercept

Slope m = (y₂ -y₁)/(x₂ - x₁)

In our case,

Slope = (70 - 60)/70 - 60

m = 10/10 = 1

Thus the equation of a line:

y = x + b

Since, the line goes from (60, 60)

60 = 60 + b

b = 0

Thus, the final equation of the line will be y = x

Therefore, the linear regression equation for the given Dot plot is y = x.

the cost of popcorn machine is $15. So we should add it to 100$

Then it is 115$. This is the amount that team A need

The cost of additional supplies for the popcorn is $0.05 per bag & team A will sell the bags of popcorn for $0.50 each. then the profit that the team A can gain by selling a bag is,

[tex]0.50 - 0.05 = 0.45[/tex]

The two equations would be 1.5x + 2.5y = 30, 3x + 1.5y = 40, when we add both the equations we get, 4.5x + 4y = 70, and the value of x is 10.

To solve a system of linear equations in two variables using the substitution in two variables using the substitution method. First solve one of the equations for one variable. Substitute this in the other equation in terms of a single variable. Then solve it for the variable. Now, substitute it in any of the equations to get the value of another variable.

Given:

Add the two equations together:

1.5x + 2.5y = 30

3x + 1.5y = 40

(1.5x + 3x) + (2.5y + 1.5y) = (30 + 40)

4.5x + 4y = 70

Isolate the x-variable by subtracting 4y from both sides of the equation:

4.5x + 4y = 70

4.5x + 4y - 4y = 70 - 4y

4.5x = 70 - 4y

Divide both sides of the equation by 4.5 to solve for x:

4.5x = 70 - 4y

4.5x/ 4.5 = (70 - 4y)/4.5

x = (70 - 4y) / 4.5

Substitute the value of y from the first equation:

1.5x + 2.5y = 30

2.5y = 30 - 1.5x

y = (30 - 1.5x) / 2.5

Substitute the value of y into the equation for x and solve:

x = (70 - 4y) / 4.5

x = (70 - 4((30 - 1.5x) / 2.5)) / 4.5

x = 10

The distance from the point for the line is (0; -1; 1).

A line is a set of points that lie on the same straight path, extending in opposite directions without end.

To find the distance from the point (1; 2; 3) to the line that contains the two points (1; 3; 2) and (5; 7; 4), we can use the vector formula.

First, we need to find the direction vector of the line by subtracting the first point from the second point:

=> (5; 7; 4) - (1; 3; 2) = (4; 4; 2).

Next, we need to find a vector that connects the point to the line, which is

=> (1; 2; 3) - (1; 3; 2) = (0; -1; 1).

Finally, the magnitude of this cross product is the distance from the point to the line.

Molly is building a model roller coaster that is based on the Millennium Force in Cedar Point, which is 94 meters tall. To create a model of the roller coaster, she is using a scale of 1 centimeter to 4 meters. This means that for every 1 centimeter on the model, it represents 4 meters in the actual height of the roller coaster.

To find the height of the model, we need to divide the actual height of the roller coaster by the ratio of meters per centimeter. That is:

Height of the model = 94 meters / (1 centimeter / 4 meters)

Height of the model = 94 meters * 4 meters / 1 centimeter

Height of the model = 376 meters / 1 centimeter

As a result, the x-coordinate of the point on the curve closest to the origin is 2.

Coordinates are a pair of integers that are used to locate a point or object in a two-dimensional plane. A point's location on a 2D plane is defined by two integers called the x-coordinate and the y-coordinate. The distance of a point from the y-axis scaled with the x-axis is known as its abscissa or x coordinate. The ordinate is the distance of a point from the x-axis scaled with the y-axis. Coordinates are the abscissa and ordinate combined. To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate.

Here,

The x-coordinate of the point on the curve that is closest to the origin can be found by minimizing the distance between the point on the curve and the origin. The distance between two points (x1, y1) and (x2, y2) is given by the Pythagorean theorem:

d = √((x2 - x1)^2 + (y2 - y1)^2)

For the origin and a point on the curve, we have x1 = y1 = 0, so the distance between the origin and a point (x, y) on the curve is:

d = √(x^2 + y^2)

Using the equation of the curve, we have y = 2 * √(9 - x), so the distance can be expressed as:

d = √(x^2 + (2 * √(9 - x))^2)

= √(x^2 + 4(9 - x))

= √(x^2 + 36 - 4x)

To find the x-coordinate of the point that minimizes d, we can use calculus. Setting the derivative of d with respect to x equal to zero and solving for x, we obtain:

d' / dx = 2x - 4 = 0

x = 2

So the x-coordinate of the point on the curve that is closest to the origin is 2.

Define array C as an array of length n with all values zero for i = 1 to n

C[i] = t / A[i] // Note use INTEGER arithmetic here

t = C[i] mod A[i] // Note using integer modulo here to get the remainder

end fo ... ro

return C

An easy counterexample would be to use V = ( 5, 3, 1 ), and t= 9. The greedy algorithm will return values ( 1, 0, 4), but a little intuition shows that the array ( 0, 3, 0 ) will use fewer coins.

c) If we consider the array A = ( kn-1, kn-2, ..., k0), and k >0, then we can see that for any k < (n-1), there will be at most (k-1) coins of that value; if there had been sufficient \"value\" remaining to select k coins o that value, the greedy algorithm would have selected one more coin of the next coin up. Another way to look at this is that for any selection by the greedy algorithm from ki ... k0, the value MUST be less than ki+1, since ki+1 is by definition a multiple of k.

Therefore, the correct answer is C) 1.00 x + 3.00 y.

In mathematics and computer science, a vector is an ordered list of numbers that can be used to represent things like position, direction, and magnitude. Vectors can be added and subtracted, and they can be multiplied by scalars (numbers).

To subtract two vectors, we need to subtract the corresponding components. So, the x-component of vector C is

(-3.00 x) - (-2.00 x) = -3.00 + 2.00

= 1.00

and the y-component of vector C is

y'' p(x)y' q(x)y = [y1''(x) y2(x) + 2y1'(x) y2'(x) + y1(x) y2''(x)] p(x) [y1'(x) y2(x) + y1(x) y2'(x)] q(x) [y1(x) y2(x)]

= [y1''(x) p(x)y1'(x) + 2y1'(x) p(x)y2'(x) + y1(x) y2''(x) p(x)] q(x) [y1(x) y2(x)]

= [r1(x) + r2(x)] q(x) [y1(x) y2(x)]

= r1(x)r2(x) q(x) [y1(x) y2(x)]

Since this is equal to y″ p(x)y′ q(x)y, it follows that y(x) = y1(x) y2(x) is a solution of y″ p(x)y′ q(x)y = r1(x) r2(x). We can prove this using the product rule. Let y(x) = y1(x) y2(x). Then:

y'(x) = y1'(x) y2(x) + y1(x) y2'(x)
