Three brothers each purchase two chili dogs and an order of tater tots. The tater tots cost $2.50. If their grand total was $34.50, then how much did each chili dog cost?

The coordinate of point k is (-5,0) with the given transformation and the coordinate of point P is (9,-2).

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

14)

The K'(-8,6) is become by the rule x - 3 and y + 6

So, x - 3 = -8 → x = -8 + 3 = -5

y + 6 = 6 → y = 0

So the coordinate of point K is (-5,0).

15)

The point P'(1,-2) is translated along the vector {-8,0} so -8 means x - 8 and 0 mean y - 0.

Therefore, x - 8 = 1 → x = 1 + 8 = 9

y - 0 = -2 → y = -2 so coordinate is (9,-2).

Hence "The coordinate of point k is (-5,0) with the given transformation and the coordinate of point P is (9,-2)".

The correct answer to the given question about chi-square distribution and sampling distribution is a. 5 or higher.

The chi-square distribution provides a good approximation to the sampling distribution of the chi-square statistic only if the sample size is large. Generally, a sample size of 5 or higher is considered large enough for this approximation. This is because the chi-square distribution approaches a normal distribution as the degrees of freedom increase, and a sample size of 5 or more provides enough degrees of freedom for the approximation to be valid. However, if any expected count is less than 5, then the approximation may not be reliable, and alternative methods should be considered (such as Fisher's exact test or the Monte Carlo method).

The present value of the loan is found to be  approximately $70.28.

To find the present value of a loan, we can use the formula:

Present Value = Future Value / (1 + (interest rate * time))

Given that the future value is $1,321.17, the interest rate is 7.75%, and the time is 230 days, we can plug in these values into the formula:

Present Value = 1321.17 / (1 + (0.0775 * 230))

Calculating the expression in the parentheses first:

Present Value = 1321.17 / (1 + 17.8075)

Simplifying further:

Present Value = 1321.17 / 18.8075

Evaluating the division:

Present Value ≈ $70.28

Therefore, the present value of the loan is approximately $70.28.

The axis of symmetry and vertex of the graph of 2 - 12x + 2 y = 3x  The correct answer is b. Axis: x = 2 Vertex: (2, 2).

To find the axis of symmetry and vertex of a graph, we need to manipulate the given equation into vertex form, which is in the form of (x - h)^2 = 4p(y - k), where (h, k) represents the vertex.

Starting with the given equation 2 - 12x + 2y = 3x, we rearrange it as 3x - 2y = -2. Next, we isolate the x term by subtracting 3x from both sides: -2y = -3x - 2. Then, we divide both sides by -2 to get y isolated: y = (3/2)x + 1.

Comparing this equation to the vertex form, we see that the coefficient of x is 3/2, which is equivalent to 6/4 or 1.5. This tells us that the vertex lies on the line x = 2. Therefore, the correct answer is b. Axis: x = 2 Vertex: (2, 2).

The factoring of the expression 9 x²+48 x+64 is (3x+8)²

To solve this exercise, we have to follow the rules of factoring:

9 x²+48 x+64

1. Factor 48 from 48x:

9 x²+48 x+64

9 x²+(24+24) x+64

2. Apply the distributive property:

9 x² + 24x + 24x + 64

3. Groups the first two terms and the last two terms:

(9 x² + 24x) + 24x + 64

4. Factorize the greatest common denominator (GCM) of each group:

3x(3x + 8x) + 8(3x + 8)

5. Simplify the common term (3x + 8) with the distributive property:

(3x+8) (3x+8)

The term that best represents the intersection of two pages of an open book is point.

A third item made up of everything that is simultaneously contained in all of the other things is called an intersection of two or more objects in mathematics. In Euclidean geometry, for instance, the intersection of two lines in a plane that are not parallel is where they come together. More broadly, the set of elements that are a part of all of the sets is what is meant by the intersection of sets in set theory. The items being considered do not need to be in a shared space, unlike the Euclidean concept.

A point is the most frequent shape for an intersection in plane geometry, while there are other shapes that can be used as well. An intersection is an item of lesser dimension that is incident to each in incidence geometry, which is typically applied to flats.

The Rpm is 9000 and maximum Horsepower cannot be determined Finding the maximum of the function will help us determine the RPM at which the engine is producing the most horsepower.

To do it, we must calculate its derivative and set it to zero:

d(HP)/d(RPM) = 0.5 × (9000 - RPM)\(x^{-0.5}\)

When we solve for RPM by setting this equal to zero, we obtain:

0 = 0.5 × (9000 - RPM)\(x^{-0.5}\)

(9000 - RPM)\(x^{0.5}\) = 0

9000 - RPM = 0

RPM = 9000

So, at 9000 RPM, the most horsepower is produced. At this RPM, we only evaluate the function to determine the maximum horsepower:

HP = 0.5 × (9000 - RPM)\(x^{-0.5}\) × RPM\(x^{2}\)

HP = 0.5 × (9000 - RPM)\(x^{-0.5}\) × RPM\(x^{2}\) × 9000\(x^{2}\)

HP = 0.5 × (0)\(x^{-0.5}\) × 9000\(x^{2}\)

HP = 0.5 × infinity × 9000\(x^{2}\)

However, since infinity is not a mathematical concept, computations cannot use it. It indicates that as RPM near 9000, the engine's power output increases significantly, but the engine's maximum horsepower cannot be precisely measured.

Answer:

Option D --->  y=5x

When a line is directly proportional it means it crosses the origin so has a y- and x-intercept of 0.

So if we use the format y=mx+c, it will work but our c value will be 0 as I explained above .

To work out the gradient we simply take 2 points (0,0) and (1,5)) on the graph and use the gradient formula :

m = change in y ÷ change in x

m = 5÷1

m = 5

Answer:

yes

Step-by-step explanation:

The slope of the line m is -2 if the line passes through (4, -3) and (0, 5) the answer is -2.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)

From the graph:

(4, -3) and (0, 5)

The slope of the line m = (5+3)/(-4)

The slope of the line m = -2

Thus,  the slope of the line m is -2 if the line passes through (4, -3) and (0, 5) the answer is -2.

The probability of of a random student having blue eyes and dark hair

 is 35% .

let consider the total students in the school be (U) = 100%

out of them ,

students having blue eyes (A) = 60%

students having  dark hair (B) = 55%

students with neither blue eyes nor dark hair (A∪B)' = 20%

let the students with blue eyes and dark hair be (A∩B) = x %

Then according to the set theorem

U = n(A∪B) + n(A∪B)'

U = n(A) + n(B) - n(A∩B) + n(A∪B)'

100 = 60 + 55 - x +20

∴ x = 60 + 55 +20 - 100

x = 35 %

The given numbers are −6.809 and −6.812.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Comparing decimals involves starting with the digits having the highest place value, just like when comparing other whole numbers. We begin the comparison by putting the provided decimal numbers in a place value table. We move on to the digits in the next place to the right if the digits on the biggest place value match. Up till the digits that are different are reached, we continue comparing digits.

Answer: 5.824 m / min

Step-by-step explanation:

Change in position = -2.1m to -38.6m

Distance = |-38.6 m - (-2.1m) |

=|-36.5| m

= 36.5 m

Time = \(6\dfrac14\ min=\dfrac{6\times4+1}{4}\ min\)

\(=\dfrac{25}{4}\ min\)

The average change in Michelle's position each minute = \(\dfrac{36.5}{\dfrac{25}{4}}\text{ m/min}\)

\(=\dfrac{36.4\times4}{25}\text{ m/min}\\\\= 5.824\text{ m/min}\)

Hence, the average change in Michelle's position each minute = 5.824 m / min

\(\text{Average Weight}=\frac{1}{8}\sum\limits^{8}_{i=1}{X_{i}}\)

Step-by-step explanation:

The average value of a data set is the representation of the central tendency of the data set, i.e. the average of a set is the measure of center.

The formula to compute the average of a data set is:

\(\text{Average}=\frac{1}{N}\sum\limits^{N}_{i=1}{X_{i}}\)

Here,

N = number of observation in the data set

\(\sum\limits^{N}_{i=1}{X_{i}}\) = sum of all the observations

It is provided that the line plot shows the weights of the 8 kittens at 3 weeks old.

So, there are a total of N = 8 kittens.
