The slope of a line parrallel to the line whose equation is 8x+10y = 60 is -4/5

The standard form of a equation of a line is y = mx + c

The line whose equation is 8x+10y = 60

10y = -8x + 60

y = 1/10(-8x + 60)

y = -4/5 x + 6

The slope of the line is -4/5

When two lines are parallel the slope of both the lines is equal

so, the slope of the line parallel is same as the slope of the line  8x+10y = 60

Therefore, the slope of a line parrallel to the line whose equation is 8x+10y = 60 is -4/5

Therefore, the 90% confidence interval for the mean height of the population of female runners is (64.77, 66.83) inches.

A confidence interval is a range of values that provides an estimate of the unknown population parameter with a certain level of confidence. The confidence level represents the percentage of times that the true population parameter will be contained within the interval, based on repeated sampling.

a) Using a t-distribution with 11 degrees of freedom (n-1), and a 90% confidence level, the t-value is 1.796.

The left boundary of the confidence interval is:

65.80 - (1.796 * (1.95 / √(12))) = 64.77 inches (rounded to two decimal places)

b) The right boundary of the confidence interval is:

Answer:

\(y=\frac{3}{10} x-\frac{16}{5}\)

Step-by-step explanation:

Equation for slope:

\(m=\frac{y_{1}- y_{2} }{x_{1}- x_{2} }\)

Substitute in your x and y values:

\(m=\frac{-2+5}{4+6} \\ m=\frac{3}{10}\)

Now write the equation:

\(y=\frac{3}{10} x\)

this is not done yet though since it does not work:

\(-2=\frac{3}{10} *4\\-2=1\frac{1}{5}\)

so we add the y- intercept \(b\) to make the equation equal:

\(-2=1\frac{1}{5}+b\)

From here we solve for \(b\):

\(b=-\frac{16}{5}\)

\(y=\frac{3}{10} x-\frac{16}{5}\)

In each case, the dimension of the subspace of P_3 spanned by the given sets can be found by determining the linear independence of the vectors within each set.

1. S = span{x, x - 2, x^2 + 2}
The given vectors are linearly independent, as there is no scalar multiple or linear combination of the first two vectors that can result in the third vector. Therefore, dim(S) = 3.

2. S = span{x, x - 2, x^2 + 2, x^2 - 2}
The first three vectors are linearly independent, as previously determined. The fourth vector, x^2 - 2, can be obtained by subtracting the second vector (x - 2) from the third vector (x^2 + 2), making the fourth vector linearly dependent on the other vectors. Thus, dim(S) = 3.

3. S = span{x^2, x^2 - x - 2, x + 2}
These vectors are linearly independent, as there is no scalar multiple or linear combination of any two vectors that can result in the third vector. Therefore, dim(S) = 3.

4. S = span{3x, x - 3}
The given vectors are linearly independent since neither vector is a scalar multiple of the other. Therefore, dim(S) = 2.

Let

The number is soil = x

The number of plants = y

You are buying plants and soil for your garden.

You want to buy at least 5 plants

At least = greater than or equal to with the inequality sign(≥)

Hence:

Answer:

696

Step-by-step explanation:

\(\frac{m}{8} = 87\)

First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).

\(m=87*8\\m = 696\)

Because any number divided by 1 would just be itself, 696/1 is just 696.

Answer: m/1= 7.125 or 7.1 (rounded)

Step-by-step explanation:

if m/8=57 then m/1 multiplied by 8 would be 57 . so you do the opposite and divide 57 by 8.

The mathematical expression y(x,t) = Asin(kx)sin(wt) provides a way to describe the behavior of a standing wave in terms of its amplitude, frequency, and location along the string.

At time t=0,

the standing wave can be mathematically expressed as

y(x,0) = Asin(kx)sin(w*0) = Asin(kx)sin(0) = 0.

This means that the displacement of the string is zero at time t=0.

However, it is important to note that this does not mean that the string is not moving at all. Rather, it means that the string is in a state of equilibrium at time t=0, with the maximum transverse displacement being A.

As time progresses, the standing wave will oscillate between the maximum positive and negative transverse displacement values, creating a pattern of nodes (points of zero displacements) and antinodes (points of maximum displacement).

The wave number k and angular frequency w are both constants that are dependent on the physical properties of the string and the conditions under which the wave is being produced.

The 4P model of resisting corruption is a useful framework that can be utilized to combat corruption. It emphasizes the importance of prevention, punishment, promotion, and participation.

The 4P model is a method of combating corruption by focusing on becoming more aware of it. It is a framework that includes four elements:

Prevention, Punishment, Promotion, and Participation.

The first component of the 4P model is prevention, which entails identifying and eliminating the underlying causes of corruption. The objective is to minimize the opportunities for corruption and to promote ethical behavior.

This can be achieved through the establishment of strong policies and regulations, as well as the implementation of accountability mechanisms.

The second element of the 4P model is punishment. When corruption occurs, penalizing those who engage in it is critical to deter others from doing so. This entails implementing strict laws and regulations and ensuring that those caught face harsh consequences.

The third component of the 4P model is promotion. This element is all about promoting transparency and ethical conduct. The aim is to create a culture of integrity where people are encouraged to do the right thing and transparency is prioritized.

The variance of X is 0.09.

Formula used: Variance is the square of the standard deviation. T

he formula to calculate variance of a discrete random variable X is given by:

Var(X) = E[X²] - [E(X)]²Calculation:

P(B) = 0.2P(A)

= 0.5P(AB) =

0.1

By definition,

P(A U B) = P(A) + P(B) - P(AB)

⇒ P(A U B) = 0.5 + 0.2 - 0.1

⇒ P(A U B) = 0.6

Now,E[X] = E[1B + ?]

⇒ E[X] = E[1B] + E[?]

Since 1B can have two values 0 and 1.

So,E[1B] = 1*P(B) + 0*(1 - P(B))

= P(B)

= 0.2P(A/B)

= P(AB)/P(B)

⇒ P(A/B)

= 0.1/0.2

= 0.5

So, the conditional probability distribution of ? given B is:

P(?/B) = {0.5, 0.5}

⇒ E[?] = 0.5(0) + 0.5(1)

= 0.5⇒ E[X]

= 0.2 + 0.5

=0.7

Now,E[X²] = E[(1B + ?)²]

⇒ E[X²] = E[(1B)²] + 2E[1B?] + E[?]²

Now,(1B)² can take only 2 values 0 and 1.

So,E[(1B)²] = 0²P(B) + 1²(1 - P(B))= 0.8

Also,E[1B?] = E[1B]*E[?/B]⇒ E[1B?] = P(B)*E[?/B]= 0.2 * 0.5 = 0.1

Putting the values in the equation:E[X²] = 0.8 + 2(0.1) + (0.5)²= 1.21Finally,Var(X) = E[X²] - [E(X)]²= 1.21 - (0.7)²= 0.09

Therefore, the variance of X is 0.09.

Let's denote the lengths of the sides of the triangle as a, b, and 6, where side b is twice the length of side a.

According to the given information, we have the following relationships:

b = 2a (side b is twice the length of side a)

c = 6 (the third side has length 6)

To determine the possible values of the lengths of the sides, we can apply the triangle inequality theorem. According to this theorem, in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Applying the triangle inequality to our triangle, we get the following inequalities:

a + b > c

a + 2a > 6

3a > 6

a > 2

b + c > a

2a + 6 > a

a > -6 (This inequality doesn't provide any meaningful information as lengths cannot be negative.)

a + c > b

a + 6 > 2a

6 > a

Combining the inequalities, we find that 2 < a < 6.

Since side b is twice the length of side a, we have 4 < b < 12.

Therefore, the possible values of the lengths of the sides of the triangle are:

2 < a < 6

4 < b < 12

c = 6

The function f(x) = (x + 1)^2 / (x - 2)(x + 2), with f(x) = 1.

The function f(x) is given as f(x) = (x^2 + 2x + 1) / (x^2 - 4). To determine f(x) and f(x), we must first factor the numerator and denominator. We can factor the numerator as (x + 1)^2, and the denominator as (x - 2)(x + 2). Thus, f(x) = (x + 1)^2 / (x - 2)(x + 2).

To determine the horizontal asymptotes, we must divide the leading terms of the numerator and denominator. The leading terms are x^2 for the numerator and x^2 for the denominator, so the horizontal asymptotes are y = 1.

Therefore, we can conclude that the function f(x) = (x + 1)^2 / (x - 2)(x + 2), with f(x) = 1.
