Step-by-step explanation:

The triangle midsegment is a very important concept in geometry, and the triangle midsegment theorem states that the midsegment of a triangle is parallel to the third side and has a length equal to half of the length of the third side

The triangle midsegment theorem states that the midsegment of a triangle is parallel to the third side of the triangle and has a length that is equal to half of the length of the third side.

In this explanation, we will define the midsegment of a triangle and explain the triangle midsegment theorem in more detail.

To begin, let's consider a triangle ABC with midpoints D and E on sides AB and AC respectively. The segment DE is the midsegment of triangle ABC.

According to the triangle midsegment theorem, the length of DE is equal to half the length of the third side of the triangle, BC. Mathematically, this can be represented as follows:

DE = BC/2

In addition to the length, the midsegment of a triangle is also parallel to the third side. This means that if we extend the midsegment, it will eventually intersect the third side of the triangle.

The triangle midsegment theorem states that the midsegment of a triangle is parallel to the third side and also has the same length as half of the third side.

it will take approximately 678.24 seconds, or about 11 minutes and 18 seconds, to earn $2,000,000 if you make $2949 per second.

Why it is?

We can use a simple formula to solve this problem:

Time = Amount / Rate

where Amount is the amount of money you want to earn ($2,000,000) and Rate is the rate at which you earn money per second ($2949).

Plugging in these values, we get:

Time = $2,000,000 / $2949 per second

Time = 678.24 seconds

when possible, the best way to establish that an observed association is the result of a cause and effect relation is by means of well designed experiment.

In an experiment, a researcher manipulates one or more variables, while holding all other variables constant. By noting how the manipulated variables affect a response variable, the researcher can test whether a causal relationship exists between the manipulated variables and the response variable. Characteristics of a Good Experimental Design:

Provides unbiased estimates of the factor effects and associated uncertainties Enables the experimenter to detect important differences Includes the plan for analysis and reporting of the results Gives results that are easy to interpret Permits conclusions that have wide validity Shows the direction of better results Is as simple as possible Basic Principles of  experimental design:

The basic principles of experimental design are

(i) Randomization

(ii) Replication

(iii) Local Control

Randomization:

Randomization is the cornerstone underlying the use of statistical methods in experimental designs.  Randomization is the random process of assigning treatments to the experimental units. The random process implies that every possible allotment of treatments has the same probability.

Replication:

By replication, we mean that repetition of the basic experiments. For example, If we need to compare the grain yield of two varieties of wheat then each variety is applied to more than one experimental units.

Local Control

it has been observed that all extraneous source of variation is not removed by randomization and replication, i.e. unable to control the extraneous source of variation. Thus we need to a refinement in the experimental technique.

Answer:

a. y = 6.5x + 3.99

b. y = 10.49x

Step-by-step explanation:

a.

total cost = charge per shirt + flat rate of shipping

y = 6.5x + 3.99

b.

total cost = charge per shirt + shipping charge per shirt

y = 6.5x + 3.99x

y = 10.49x

If the shipping charge applies to every shirt, then the total cost is the cost of the shirts (6.5x) plus the cost of shipping multiplied by the number of shirts (3.99x)

Answer:

Step-by-step explanation:

Answer:

Hi there!

Recall that slope-intercept form is:

y = mx + b

Where m = slope

In this instance, we are given a slope of 4,

therefore:

y = 4x + b

Substitute in the x and y coordinates of the point given:

0 = 4(3) + b

0 = 12 + b

Substract 12 from both side:

-12 = b

Therefore, the equation would be:

y = 4x - 12

Graph the equation by finding x and y values or using a calculator:

x = 0, y = 4(0) - 12 = 12 (0, 12)

x = 1, y = 4(1) - 12 = - 8 (1, -8)

x = 2, y = 4(2) - 12 = - 4 (2, -4)

x = 3, y = 4(3) - 12 = 0 (3, 0)

Answer:

Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .

Step-by-step explanation:

The sample proportion is p2= 7/27= 0.259

and q2= 0.74

The sample size = n= 27

The population proportion = p1= 0.4

q1= 0.6

We formulate the null and alternate hypotheses that the new program is effective

H0: p2> p1   vs  Ha: p2 ≤ p1

The test statistic is

z= p2- p1/√ p1q1/n

z= 0.259-0.4/ √0.4*0.6/27

z=  -0.141/0.09428

z= -1.496

The significance level ∝ is 0.05

The critical region for one tailed test is z ≤ ± 1.645

Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .

The vector space that has exactly one basis is the trivial vector space, which is the vector space containing only the zero vector.

A basis for a vector space is a set of linearly independent vectors that span the entire space. In a non-trivial vector space (a space that contains more than just the zero vector), there are infinitely many possible bases. This is because any set of linearly independent vectors that span the space can be used as a basis.

However, in the trivial vector space, there is only one vector (the zero vector), and it is linearly independent of itself. Therefore, the trivial vector space has exactly one basis, which is the set containing only the zero vector. Any other set of vectors in the trivial vector space is linearly dependent, and therefore cannot be used as a basis.

The first 3 terms of the sequence using the expression are -5, -4 and -1

From the question, we have the following sequence that can be used in our computation:

n(n – 2) – 4

This means that

T(n) =  n(n – 2) – 4

Set n = 1, 2 and 3

So, we have

T(1) =  1 * (1 – 2) – 4 = -5

T(2) =  2 * (2 – 2) – 4 = -4

T(3) =  3 * (3 – 2) – 4 = -1

Option (a) is correct. There'll be No Solution to the given system of linear equations.

According to the solutions of linear equations, we know the following things,
1. If two intersecting lines are at one common point, the system has only one solution.
2. If two coincidental lines mean both equations give the same line, that means the system has infinitely many solutions.
3. If the lines are parallel to each other, the system will have no solution.

We can see lines are parallel but we can also find whether the given lines are parallel or not by simply finding their slope m.

For Line 1, we have the following data
\($\left(\mathrm{x}_1, \mathrm{y}_1\right)=(0,2)$\)

\($\left(\mathrm{x}_2, \mathrm{y}_2\right)=(3,1)$\)

For slope m of the line 1,
slope m₁ = \(\frac{y_2-y_1}{x_2-x_1}=\frac{1-2}{3-0}=-\frac{1}{3}\)

For Line 2, we have the following data

\($\left(\mathrm{x}_1, \mathrm{y}_1\right)=(0,-1)$\)

\(- $\left(x_2, y_2\right)=(3,-2)$\)

For slope m of line 2,
slope m₂\($=\frac{y_2-y_1}{x_2-x_1}=\frac{-2-(-1)}{3-0-x_1}=-\frac{1}{3}$\)

As the slope of both lines is equal, so lines are parallel to each other, and hence, if lines are parallel so there'll be no solution to the system.
Hence, option (a) is correct.

Answer: a

Step-by-step explanation: A plane is a 2d surface so if it ever intersects a 3d object the cross-section will be a 2d figure, in this case, a rectangle.

Answer:

Option B.

Step-by-step explanation:

The given function is

\(f(x)=-2\sqrt{x-7}+1\)

The above function is defined if (x-7) is greater than 0.

\(x-7\geq 0\)

Add 7 on both sides.

\(x\geq 7\)

It is means domain of the function is \([7,\infty)\). So, -6 is not in domain.

We know that

\(\sqrt{x-7}\geq 0\)

Multiply both sides by -2. So, the sign of inequality will change.

\(-2\sqrt{x-7}\leq 0\)

Add 1 on both sides.

\(-2\sqrt{x-7}+1\leq 0+1\)

\(f(x)\leq 1\)

It is means range of the function is \((-\infty,1]\). So, -6 is in Range.

Since –6 is not in the domain of f(x) but is in the range of f(x), therefore the correct option is B.

Answer:

B

Step-by-step explanation:

Answer:

a. For company A:

R(0) = $1.08 million, R(15) = $6.63 million

Average rate of change:

$5.55 million / 15 years = $.37 million/year

For company B, the average rate of change is $.32 million/year

So company A's revenue had a greater average rate of change.

b. Company A will eventually have a greater revenue.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean. By calculating the deviation of each data point from the mean, the standard deviation can be calculated as the square root of variance.

Given that mean μ = 4.2 , standard deviation σ = 1.3

1. P(X >= 5) = P((X - μ)/σ >

                    = (5 - 4.2) /1.3

                    = P(Z ≥ 0.6154)

                    = 1 - P(Z < 0.6154)

                    = 1 - 0.7324

                    = 0.2676

The required probability is 0.2676.

2.Given that n = 8 then  \(\bar x\) = σ/\(\sqrt{(n)\)  = 1.3/√(8) = 0.4596

P(x-bar ≥ 5) = P((\(\bar x\) - μ)/σx-bar ≥ (5 - 4.2)/0.4596)

                        = P(Z ≥ 1.7406)

                        = 1 - P(Z < 1.7406)

Answer:

\(x=\frac{y-3}{2y-3}\)

Step-by-step explanation:

\(y=2+\frac{1+x}{1-2x}\)

First, subtract 2 from both sides:

\(y-2=\frac{1+x}{1-2x}\)

Multiply both sides by (1 - 2x):

\(y-2(1-2x)=1+x\\y-2xy-2+4x=1+x\)

Subtract 1, subtract x, and add 2xy to both sides:

\(y-3+3x=2xy\)

Subtract 3x from both sides:

\(y-3=2xy-3x\)

Factor out the x:

\(y-3=x(2y-3)\)

Finally, divide both sides by (2y-3):

\(x=\frac{y-3}{2y-3}\)

Keep in mind that this is undefined at y=1.5. The original equation is also undefined at 0.5.
