Step-by-step explanation:

Notice that, the angle QRS is external to the triangle and adjacent to the angle PRQ. According to the theorem of a external/adjacent angle, we have: m∠QRS = m∠PQR + m∠RPQ, where PQR and RPQ are internal angles.

From the hypothesis, we have:

m∠QRS =(10x−12)∘(10x−12)

m∠PQR = (3x+20)∘(3x+20)

m∠RPQ=(3x−8)∘(3x−8)

Using the first equation and replacing the hypothesis:

m∠QRS = m∠PQR + m∠RPQ

(10x−12)∘(10x−12) = (3x+20)∘(3x+20) + (3x−8)∘(3x−8)

Multiplying and applying the remarkable identity:

Then, we use a calculator to find the roots, which are:

In this case, we will see what root is the right one.

Now, we replace it into m∠QRS =(10x−12)∘(10x−12), because we need to find m∠QRS.

m∠QRS =(10x−12)∘(10x−12) = (10(4.7) - 12) (10(4.7) - 12) = (35) (35) = 1225

Answer:  y ≤ (1/2)x + 3

Step-by-step explanation:

The slope is 1/2 and the y-intercept is 3.

The linear inequality represented by the graph is \(y \le \frac 12x + 3\)

From the graph, we have the following highlights:

The first highlight implies that the inequality sign to use is ≤

The slope (m) is calculated as:

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

So, we have:

\(m = \frac{3 -4}{0-2}\)

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

\(m = \frac{1}{2}\)

The y-intercept (b) is where the line crosses the y-axis:

b = 3

The linear inequality is represented as:

\(y \le mx + b\)

So, we have:

\(y \le \frac 12x + 3\)

Hence, the linear inequality is \(y \le \frac 12x + 3\)

Answer:

A.   4.5 ft

B.    4 ft

C.    1 ft

Step-by-step explanation:

If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.

You would need to find the vertex of the parabola.  The ordered pairs would be (d, h) instead  of the normal (x, y).  

A.  The maximum height will be the h value of the vertex

B.   Let h = 0 and solve the equation for d.  That will give you distance from the stump that the frog landed.

C.  The distance from the log at the maximum height is the d value of the vertex

So, that is what is needed to be done.

Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2  (discard -2 since a distance cannot be negative)

So the answer to A is 4.5 ft.

The answer to B is 4ft.

The answer to C is 1 ft.

Now, can you find the vertex on your own and can you solve the equation when h = 0?  I hope so.  OK?

A function assigns the values. The maximum height will be when the horizontal distance is 1feet from the log.

A function assigns the value of each element of one set to the other specific element of another set.

A.) The maximum height of the frog,

h = -0.5d²+d+4

dh/dd = -0.5(2d)+1

dh/dd = -d+1

0=-d+1

d = 1

The maximum height will be when the horizontal distance is 1feet from the log.

h = -0.5(1)² + 1 + 4

h = -0.5 + 1 + 4

h = 4.5

Hence, the maximum height of the frog will be 4.5 feet.

B.) The Distance between the frog and the stump when the frog land can be found,by putting h=0.

0 = -0.5(d)²+ d + 4

d²-2d-8=0

d²-4d+2d-8=0

d(d-4)+2(d-4)=0

d = 4, -2

Since the distance can not be negative, the frog is 4 feet away from the stump when the frog land.

C.) The maximum height will be when the horizontal distance is 1feet from the log.

we need to standardize the value of 24 months using the given mean and standard deviation there is a 22.66% chance that a randomly selected customer will require a replacement within 24 months due to the battery no longer working.

Z = (x - μ) / σ
where x is the value we want to standardize (24 months), μ is the mean (30 months), and σ is the standard deviation (8 months).
Z = (24 - 30) / 8 = -0.75
Now we can use a standard normal distribution table or calculator to find the probability of a Z-score less than -0.75.
P(Z < -0.75) = 0.2266
Therefore, the probability that a customer who purchases the warranty will require a replacement within 24 months from the date of purchase because the battery no longer works is approximately 0.2266 or 22.66%.
To answer your question, we will use the normal distribution, mean, and standard deviation. The mean life span of the new battery is 30 months, with a standard deviation of 8 months. You want to know the probability that a customer will require a replacement within 24 months.
First, we need to find the z-score, which is the number of standard deviations away from the mean a given value is. The formula for the z-score is:
z = (X - μ) / σ
where X is the value we're interested in (24 months), μ is the mean (30 months), and σ is the standard deviation (8 months).
z = (24 - 30) / 8
z = -6 / 8
z = -0.75
Now we need to find the probability associated with this z-score. You can use a z-table or an online calculator to find the probability. For a z-score of -0.75, the probability is approximately 0.2266.

The system specifications may not be consistent if the router doesn't support the new address space. The reason is that the router must be compatible with the addressing scheme used by the system for proper communication.

If the router does not support the new address space, there might be issues with the system's performance or accessibility. The address space is the number of unique IP addresses that are available in a network. An IP address is required to identify each device on a network and to enable communication between devices.

With the increasing number of devices on a network, new address spaces are required to ensure that each device has a unique IP address. The compatibility of system specifications is a crucial aspect that must be considered when building a system. If the system specifications are not consistent, it might cause the system to malfunction, resulting in poor performance or accessibility issues.

The measure of angle Z is 47.19°.

Law of sines is defined as that ratio of the length of the sides of a triangle to the sine of the angle opposite to the these sides are equal.

That is, if a, b and c are sides opposite to the angles A, B and C respectively, then,

a / sin A = b / sin B = c / sin C

Given a triangle XYZ.

m ∠Y = 78°, XY = 9, XZ = 12

We have to find the measure of angle Z.

Using the law of sines,

XZ / sin Y = XY / sin Z

12 / sin (78°) = 9 / sin Z

Cross multiplying,

12 × sin Z = 9 × sin (78°)

sin Z = (9 × sin (78°)) / 12

sin Z = 0.7336

Z = sin⁻¹ (0.7336)

Z = 0.8236 radians

  = 47.19°

What is the solution of an equation?

An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution. To put it another way, a solution is a value or set of values (one for each unknown) that, when used to replace the unknowns, cause the equation to equal itself.

What is distributive property?

The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms.

Given equation is 2(4x+3)+4=3x-(2x+4).

Apply distributive property in 2(4x+3):

8x + 6 + 4 = 3x - (2x+4)

Formula for use to calculate this is

\(p_x= (number of combination)p^xq^{n-x}\)

Well, for this we use the binomial distribution probability mass function. This is because there is only two possible outcome in the roll of the die - even or odd. Thus, we know that the binomial distribution pmf is given by:

\(p_x= (number of combination)p^xq^{n-x}\)

where, p is binomial probability and n is number of trials

We know n is 10 in this case since there are 10 roll of a die. We know p is 1/2 because it is a fair die and there are 3 chances out of 6 that it will be even (or odd). We also know k is 5 because we want to find out the probability that out of 10, there will exactly be the same amount of even and odd results (which means even has to appear 5 times, odd also 5 times).

Which is basically 252*(0.03125)*(0.03125), which equals 0.246094, or .2461.

The equation 3x = 6.4 can be solved for x by dividing both sides of the equation by 3: 3x/3 = 6.4/3; x = 2.13

So, for 3x and 6.4x to be equal, x must be equal to 2.13. This means that you need to multiply the number 6.4 by 2.13 to equal 3. The equation 3x = 6.4 represents the relationship between two variables, x and 3x. We are trying to find the value of x that would make 3x equal to 6.4. To do this, we divide both sides of the equation by 3. Dividing both sides of an equation by the same number does not change the relationship between the variables; it only scales down the variable's value by the same factor.

So, by dividing both sides of the equation by 3, we get:

3x/3 = 6.4/3

x = 2.13

Finally, to make 6.4x equal to 3, we need to divide 6.4 by 2.13: 6.4 / 2.13 = 3. So, we need to multiply 6.4 by 2.13 to equal 3.

The value o f c based on The Mean Value Theorem is 1

f'(c) = \(\frac{f(b)-f(a)}{b-a}\) ... (i)

Based on the question, we got equations:

f(x) = 1 + x + x² ... (ii)

By using derivative, we get:

f'(x) = 1 + 2x ... (iii)

From the question, we get:

f(a) = f(0)

f(b) = f(2)

Then we need to find the value of both f(0) and f(2):

f(0) = 1 + (0) + (0)²

f(0) = 1 ... (iv)

f(2) = 1 + (2) + (2)²

f(2) = 7 ... (v)

We also need to find the equation for f'(c) based on equation (iii):

f'(x) = 1 + 2x

f'(c) = 1 + 2c ... (vi)

We will input equations (iv) and (v) into equation (i) to find another equation of f'(c):

f'(c) = \(\frac{f(2)-f(0)}{2-0}\)

f'(c) = \(\frac{7-1}{2-0}\)

f'(c) = \(\frac{6}{2}\)

f'(c) = 3 ... (vii)

Then we will subtitute the equation (vi) with equation (vii) to find the value of c:

Answer:

119 is the value of x when y = 7

Step-by-step explanation:

Since y varies inversely with x, we can use the following equation to model this:

y = k/x, where

Step 1:  Find k by plugging in values:

Before we can find the value of x when y = k, we'll first need to find k, the constant of proportionality.  We can find k by plugging in 49 for y and 17 for x:

Plugging in the values in the inverse variation equation gives us:

49 = k/17

Solve for k by multiplying both sides by 17:

(49 = k / 17) * 17

833 = k

Thus, the constant of proportionality (k) is 833.

Step 2:  Find x when y = k by plugging in 7 for y and 833 for k in the inverse variation equation:

Plugging in the values in the inverse variation gives us:

7 = 833/x

Multiplying both sides by x gives us:

(7 = 833/x) * x

7x = 833

Dividing both sides by 7 gives us:

(7x = 833) / 7

x = 119

Thus, 119 is the value of x when y = 7.

For a sample of rating of an automobile manufacturer's van regarding rating of 28.3 miles/gallon (mpg), the Z-test statistic value is equals to the -1.631.

Z-test is a parametric test. When the sample size is sufficiently large, it is mostly used. This test statistic is computed a standard normal distribution. It is then compared with the critical value (obtained from z-table). If the test statistic value is greater than it, there is evidence to reject the null hypothesis. We have an automobile manufacturer with its van rating. A sample of 200 vans is randomly considered. Sample size, n = 200

Mean of rating = 28

Standard deviations = 2.6

Lavel of significance= 0.01

To test the firm'claim we have to consider hypothesis testing here. Since it is claimed by an automobile manufacturer that its car has a 28.3 miles/gallon (MPG) rating, therefore, the null hypothesis and alternative can be stated as:

\(H_0 :μ = 28.3\)

\(H_a :μ≠28.3\)

Now, to determine the value of the test statistic, consider the Z-test : \( z = \dfrac{{M - \mu }}{{\dfrac{\sigma }{{\sqrt n }}}}\)

where, M -> mean

n --> sample size

Substitute all known values in above formula, \(= \dfrac{{28 - 28.3}}{{\dfrac{{2.6 }}{{\sqrt {200} }}}}\\\)

\(= \dfrac{{-0.3}}{{\dfrac{{0.26 }}{{\sqrt {2} }}}}\\\)

=> z = - 1.631

Hence, required test statistic value is -1.631.

h(0) = -16(0)² + 80(0) + 1

h(0) = 1

We can find the time at which the vertical velocity is zero by finding the vertex of the parabolic function. The vertex can be found using the formula:

t = -b/2a

where a = -16 and b = 80. Substituting these values into the formula gives:
