A conclusion which can be inferred about an individual score that corresponds to a z-value of 1.0 is that: c.) it is likely to come from the healthy distribution.

A z-value is also referred to as a z-score or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.

In Statistics, z-values can either be positive or negative and it can be calculated by using this formula:

\(Z=\frac{x\;-\;u}{\delta}\)

Where:

Since the individual score that corresponds to a z-value of 1.0, we can reasonably infer and logically conclude that an individual score is likely to come from the healthy distribution.

I don't know how to type the process

The constant of variation, k for the given table is 0.0725 which is the third option.

There is a table given with values of x and y.

We have to find the value of the constant of variation, k for the table.

We can write the relationship of x and y as :-

y = kx

k = y/x

Hence,

Putting the value of x = 4 and y = 0.29 , we get

k = 4/0.29 = 0.0725

We can also use any other of the values of x and y and we will get the same result.

12/0.87 = 36/2.61 = 60/4.35 = 0.0725.

Answer: 1/5

Step-by-step explanation:

So we have a total of 15 pens and 3 of those pens we know are red. The probability of randomly selecting a red pen would be 3/15 or simplified 1/5

Answer:

1/5

Step-by-step explanation:

** numbers of chances you can pick/total chances of that you can pick anything

--> # of chances you can pick red pens, in this case, is 3, since there are only 3 red pens -->3/total

--> in this case total should be every numbers of pens added --> 3+8+4 = 15

--> 3/15 -->simplify: 1/5

Answer:

The possible lengths of TR : TR = 17, 40, 42, 52,

Step-by-step explanation:

Given: Triangle WTR with WT = 25 and WR = 40. Identify all possible lengths for TR.

To find the possible lengths of the third side of a triangle:

c - a< b > a + c

a = WT = 25

c = WR= 40

b = TR = ??

40 - 25 < b < 40 + 25

15 < b < 65

The possible lengths of TR has to be greater than 15 and less than 65, Hence: TR = 17, 40, 42, 52,

Answer:

8,900

Step-by-step explanation:

Given Number: 8,937.2546

Determine the two consecutive multiples of 100 that bracket 8,937.2546

8,937.2546 is between 8,900 and 9,000

8,950 is the midpoint between 8,900 and 9,000

As illustrated on the number line, 8,937.2546 is less than the midpoint (8,950)

Therefore, 8,937.2546 rounded to the nearest hundred = 8,900

The value of x that makes the given image to be a rectangle is: x = 2.5

The length of the diagonals of a rectangle are equal and congruent to each other. It is also pertinent to note that the diagonals of a rectangle bisect each other at the center. Thus:

From the given parameters, we see that half of the diagonals have been labelled and as such we have:

8x - 3 = 4x + 7

Rearrange to have like terms on same side and so we have:

8x - 4x = 7 + 3

4x = 10

x = 10/4

x = 2.5

Thus, the value of x from the calculation above of the rectangle is 2.5

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

Domain: {x | x is a real number}

Option D, "{x | x is a real number}" accurately represents the domain of the function.

The domain of the step function f(x) = [2x] - 1, where [2x] represents the greatest integer less than or equal to 2x, can be determined by considering the restrictions on the input values.

In this case, the step function is defined for all real numbers. However, the greatest integer function imposes a restriction. Since the greatest integer function only outputs integers, the input values (2x) must be such that they produce integer outputs.

For any real number x, the greatest integer less than or equal to 2x will always be an integer. Therefore, the domain of the function f(x) = [2x] - 1 is:

(a) Linear system of equations: \($f(-12) = f(12)$, $f^{'}(-6) = f^{'}(6)$, $f^{''}(-6) = f^{''}(6)$, $f(-6) + f(6) = 24$\)

To find the solutions, we first differentiate f and obtain f'(x) = 4a3x3+ 2a2x + α1.

Using the stationary point condition, we have f'(-6) = f'(6) = 0, which gives the following equations: 864a + 6α1 + 2a2 = 0 and -864a + 6α1 - 2a2 = 0Differentiating f' gives f''(x) = 12a3x2 + 2a2.

Using the second derivative test, we have f''(-6) < 0 and f''(6) > 0, which gives 72a - 12a2 < 0 and 72a + 12a2 > 0 respectively.

Adding these two equations gives 144a > 0 or a > 0.Using the condition f(-12) = f(12) gives the equation -20736a + 1728a3 - 144α1 + 4a2 = 0.

Finally, the condition for the total water consumption can be expressed as f(-6) + f(6) = 24, which gives -144a + 12a3 + 6α1 + 2a2 = 24The final system of linear equations is:

\($$\begin{matrix}-20736a + 1728a^3 - 144α_1 + 4a^2 &=& 0\\ 864a + 6α_1 + 2a^2 &=& 0\\ -864a + 6α_1 - 2a^2 &=& 0\\ -144a + 12a^3 + 6α_1 + 2a^2 &=& 24 \end{matrix}$$\)
(b) Solving the system of equations using Gaussian elimination:

\($$\begin{pmatrix} 1 & 0 & 0 & 0 & -\frac{1}{2} \\ 0 & 1 & 0 & 0 & \frac{5}{36} \\ 0 & 0 & 1 & 0 & \frac{25}{288} \\ 0 & 0 & 0 & 1 & \frac{15}{32} \\ \end{pmatrix}$$This gives a = $\frac{1}{288}$, α1 = $\frac{5}{6}$, a2 = $\frac{25}{576}$,\)

which can be used to find f using f(x) = $\frac{1}{288}(x^4+3x^3-25x^2+180x+288)$
(c) The solution to the linear system of equations in (a) gives the function \(f(x) = $\frac{1}{288}(x^4+3x^3-25x^2+180x+288)$.\)

Therefore, this is the only function that satisfies all the given data.
(d) It is not possible that the total water consumed during the night hours from 1am to 5am is smaller than 2 (that is the average over these four hours is less than half of the daily average).

Proof:If we let g(x) denote the amount of water used during the night hours, then the total water usage is 24 = f(-12) + g(x) + f(12). Note that f(-12) = f(12), which gives g(x) = 12. Hence, the average over the four hours is g(x)/4 = 3, which is greater than half of the daily average. Therefore, it is not possible for the average to be less than 2.

The question provides all the necessary data to determine the function f(x) that models the daily water usage of a Melbournian family. We are given that the function is a polynomial of degree 4, and that it passes through (12, f(12)) and (-12, f(-12)). We are also given that x=- -6,6 are stationary points of the function and that the total water consumption during the day equals 24. Using these conditions, we are able to write a system of linear equations that determines the coefficients of the polynomial.

We then use Gaussian elimination to solve the system and obtain the function f(x). Finally, we show that it is not possible for the total water consumed during the night hours from 1am to 5am to be smaller than 2, and that the function f(x) satisfies all the given data.

19. An equation in polar coordinates of the form r = ±√5

20. An equation in polar coordinates of the form r = 5secθ

21. An equation in polar coordinates of the form r = secθtanθ

Given that,

We have to convert to an equation in polar coordinates of the form r = f(θ).

We use Jacobian properties to solve the equation.

19. x² + y² = 5

We know that,

x = rcosθ

y = rsinθ

x² + y² = r²cos²θ + r²sin²θ

x² + y² = r²(cos²θ + sin²θ)

x² + y² = r²(1)

x² + y² = r²

So, x² + y² = 5

r² = 5

Taking square root on both sides,

r = ±√5

Therefore, an equation in polar coordinates of the form r = ±√5

20. x = 5

We know that,

x = rcosθ

So,

x = 5

rcosθ = 5

r = 5secθ

Therefore, an equation in polar coordinates of the form r = 5secθ

21. y = x²

We know that,

x = rcosθ

y = rsinθ

rsinθ = r²cos²θ

Dividing r on both sides

sinθ = rcos²θ

r = \(\frac{sin\theta}{cos^2\theta}\)

r = secθtanθ

Therefore, an equation in polar coordinates of the form r = secθtanθ
