The 7-inch chord can be divided into three parts, one with a length of 3 inches and two with a length of 2 inches.

In this problem we have a chord of 7 inches long that must be divided into three parts such that one part is a inch longer than any of the two other parts. Mathematically speaking, the situation is represented by the following linear equation, which is resolved afterwards:

x + x + x + 1 = 7

3 · x + 1 = 7

3 · x = 6

x = 2

In consequence, the 7-inch chord can be divided into three parts, one with a length of 3 inches and two with a length of 2 inches.

Answer:

1/8

Step-by-step explanation:

A “standard number cube” has six sides, marked 1 2 3 4 5 and 6. Of those, exactly half are even and exactly half are odd, so we can dispense with the 6 part and just go 1/2 (the same as 3/6, after all)

So the first roll is even half the time. If it is, the second roll is odd half the time, so the chances of an even then odd pair are 1/2*1/2=1/4.

If those two happen in the correct order, the chances of the third roll being even are again 1/2… so we have 1/2*1/2*1/2=1/8

Step-by-step explanation:

Transformation in math refers to the process of changing the position, size, or shape of a geometric figure.

Geometric transformations can be divided into four main categories:

Translation: A translation is a transformation that slides a geometric figure in a specific direction without changing its shape or orientation. The distance and direction of the movement are specified by a vector.

Rotation: A rotation is a transformation that turns a geometric figure around a fixed point called the center of rotation. The shape and size of the figure remain unchanged, but its orientation is different.

Reflection: A reflection is a transformation that flips a geometric figure over a line called the line of reflection. The shape of the figure remains the same, but its orientation is reversed.

Scaling: Scaling is a transformation that changes the size of a geometric figure. It can be either a uniform scaling, where the figure is enlarged or shrunk by the same amount in all directions, or a non-uniform scaling, where the figure is stretched or compressed in different directions.

These four types of transformations can be combined to create more complex transformations, such as a rotation followed by a translation. Transformations are important in many areas of mathematics, including geometry, linear algebra, and calculus. They have applications in fields such as computer graphics, robotics, and physics.

The dot plot that represents the data in the table is: D.

If we have a given set of data values of a data distribution, "x" can be used to represent each of the data point in the data set. The number of "x" on a data point, tells the frequency of the data point that is displayed by a dot plot.

To construct the dot plot given in the diagram, find the frequency of each data point. Thus, we would have the following:

50 - 3

60 - 2

80 - 3

90 - 8

100 - 4

Thus, the dot plot in option D displays the exact number of "x" that tallies with the above frequency for each data point. Therefore, the dot plot that represents the data in the table is: D.

According to the concept of algebraic expression and arithmetic, the correct answers are A) Number of adults = N - 25. B) Number of adults when N = 124: 124 - 25 = 99

A) Let's denote the number of children as N. Since there are 25 fewer adults than children, the number of adults can be expressed as N - 25.

B) If there are 124 children, we substitute N with 124 in the expression from part A. Thus, the number of adults would be 124 - 25 = 99.

To arrive at these answers, we used the given information that there are "N" children and 25 fewer adults than children. By substituting the value of N, we determined the number of adults in terms of N and then calculated the specific number of adults when N is equal to 124.

Note: The given question is incomplete. The complete question is:

Some adults and children are watching a musical. there are 'N' number of children. There are 25 fewer adults than children.

After answering the presented question, we can conclude that As a equation result, the pizza's temperature after 5 minutes is 320°F.

In mathematics, an equation is a statement that states the equality of two expressions. An equation consists of two sides separated by an algebraic equation (=). The argument \("2x + 3 = 9," f\)or example, states that the sentence "2x Plus 3" equals the value "9." The goal of solving equations is to find the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complex, linear or nonlinear, and contain one or more parts. In the equation\("x^2 + 2x - 3 = 0,"\)the variable x is raised to the second power. Lines are used in many areas of mathematics, including algebra, calculus, and geometry.

Let T(t) be the temperature of the pizza at time t, where t is in minutes. Then,

(a) Applying the Newton's Law of Cooling calculation, we get:

(T(0) - 80) / (400 - 80) = k (where k is the proportionality constant) (where k is the proportionality constant)

When we solve for k, we get:

k = (T(0) - 80) / 320

(T(3) - 80) / (400 - 80) = (T(0) - 80) / 320

T(0) = 400 - 320 * (T(3) - 80) / 320 = 400 - (T(3) - 80) = 320 + 80 = 400°F

(T(5) - 80) / (400 - 80) = (T(0) - 80) / 320

(T(5) - 80) / 320 = (400 - 80) / 320

T(5) - 80 = 3 * (400 - 80) / 4

T(5) = 3 * 320 / 4 + 80 = 240 + 80 = 320°F

As a result, the pizza's temperature after 5 minutes is 320°F.

Answer:

slope: 5/2

Step-by-step explanation:

The equation of the quadratic function shown in the graph y - 8 = -2(x + 1)².

The vertex of this parabola is (-1, 8).  It opens downward, so the x² term has a negative coefficient.  The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).

Through the vertex form of the equation of a parabola we get:

y - (8) = a(x - (-1)) + 7, or.y - 8 = a(x + 1)².

Find coefficient a by substituting the coordinates (-3, 0) in this equation:

0 - 8 = a(-3 + 1)^2, or

-8 = a(-2)² or a = -2

The desired equation is y - 8 = -2(x + 1)^2

Answer:

(6³×2^6)÷2³=6³×2^(6-3)=6³×2³=(6×2)³=12³is your answer(1728)

Solution:

To test the hypothesis is that the mean ozone level is different from 4.40 parts per million at 1% of significance level.

The null hypothesis and the alternative hypothesis is :

\($H_0: \mu = 4.40$\)

\($H_a: \mu \neq 4.40$\)

The z-test statistics is :

\($z=\frac{\overline x - \mu}{\left( \sigma / \sqrt n \right)} $\)

\($z=\frac{4.2 - 4.4}{\left(0.7 / \sqrt{23} \right)} $\)

\($z =\frac{-0.2}{0.145}$\)

z = -1.37

The z critical value for the two tailed test at 99% confidence level is from the standard normal table, he z critical value for a two tailed at 99% confidence is 2.57

So the z critical value for a two tailed test at 99% confidence is ± 2.57

Conclusion :

The z values corresponding to the sample statistics falls in the critical region, so the null hypothesis is to be rejected at 1% level of significance. There is a sufficient evidence to indicate that the mean ozone level is different from 4.4 parts per million. The result is statistically significant.
