The discriminant of f(x)is -28, and f(x) has no distinct real number zeros.

The expression\(b^{2}- 4ac\) gives the value of discriminant of the quadratic function with the form f(x) = \(ax^{2} + bx + c\). This result is obtained through using this formula on the quadratic function, where f(x) = \(-4x^{2}+ 10x - 8\):  \(b^2 - 4ac = (10)^2 - 4(-4)(-8)\) = 100-128 = -28. Hence, -28 is the discriminant of f(x).

The discriminant informs us of the characteristics of the quadratic equation's roots. There are two unique real roots if the discriminant index is positive. There is just one real root (with a multiplicity of 2) if the discriminator is zero. There are only two complicated roots (no real roots) if discrimination is negative.

Given that f(x)'s discriminant is minus (-28), we can conclude that there are no true roots. F(x) contains two complex roots as a result. This is further demonstrated by the fact that the parabola widens downward and does not cross the x-axis, as indicated by the fact that the coefficient of the \(x^{2}\) term in f(x) is negative.

Step-by-step explanation:

The graph of the function y=3x+1 is shown.

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

We are given that;

The function is y=3x+1

Now,

When x = 0, y = 3(0) + 1 = 1, so one point on the function is (0, 1).

When x = 1, y = 3(1) + 1 = 4, so another point on the function is (1, 4).

When x = -1, y = 3(-1) + 1 = -2, so a third point on the function is (-1, -2).

Therefore, the graph will be given the attachment

The formula of finding mean :- sum of terms

number of terms

91+90+87+79+58=405

5. 405/5=81/1.

The mean is 81/1.

The following are the measures of angles and sides using the sine and cosine rules:

1). QR = 15, m∠P = 52°, m∠Q = 43°

2). BC = 21, DC = 10.4, m∠C = 22°

3). VX = 10.7, WX = 10.2, m∠V = 39°

4). HF = 18.4, m∠H = 28.7, m∠F = 15.3

The sine rule is a relationship between the size of an angle in a triangle and the opposing side. While the cosine rule relates the lengths of the sides of a triangle to the cosine of one of its angles.

1). Using the sine rule:

19/sin85 = 13/sunQ

Q = sin⁻¹[(13 × sin85)/19] {cross multiplication}

Q = 43

m∠P = 180° - (85 + 43) = 52°

QR = sin⁻¹[(19 × sin52)/sin85]

QR = 15.

2). m∠C = 180 + (19 + 139) = 22°

Using the sine rule:

BC = (12 × sin139)/sin22

BC = 21.

DC = (12 × sin19)/sin22

DC = 10.4

3). m∠V = 180 - (41 + 100) = 39°

Using the sine rule:

VX = (16 × sin41)/sin100

VX = 10.7

WX = (16 × sin39)/sin100

WX = 10.2

4). Using the cosine rule:

HF² = 7² + 13² - 2(7)(13)cos136°

HF = √338.8491

HF = 18.4

applying sine rule;

F = sin⁻¹[(7 × sin136)/18.4]

F = 15.3

m∠H = 180 - (15.3 + 136) = 28.7

Therefore, the measures of angles and sides using the sine and cosine rules are:

1). QR = 15, m∠P = 52°, m∠Q = 43°

2). BC = 21, DC = 10.4, m∠C = 22°

3). VX = 10.7, WX = 10.2, m∠V = 39°

4). HF = 18.4, m∠H = 28.7, m∠F = 15.3

When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.

The probability that you exit the row from the front rather than the back is 1/2.

The probability is calculated by dividing the total number of outcomes by the number of possible ways the event could occur. Probability and odds are two separate ideas. Odds are the possibility of something happening divided by the likelihood that it won't happen.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. In addition to being expressed as percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.

The equation of the line in slope intercept form based on the location of two points is (2x + 3).

To find the equation of line in slope intercept form, we need to calculate the slope first. The formula is -

Slope = (\( y_{2}\) - \( y_{1}\))/(\( x_{2}\) - \( x_{1}\))

Keep the values in formula

Slope = (9-1)/(3-(-1))

Add the values in numerator and denominator

Slope = 8/4

Divide the values

Slope = 2

The equation of line in slope intercept form is -

y - \( y_{1}\) = m(x - \( x_{1}[/tex)

Again keeping values

y - 1 = 2(x - (-1))

Multiply the values on RHS

y - 1 = 2(x + 1)

y - 1 = 2x + 2

Simplify the equation

y = 2x + 3

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Answer:

Point B is reflected over the y-axis to create B’. Use an ordered pair to name the location of B’, and determine the distance between point B and B'.

Step 1: Negate the x-coordinate: Multiply the x-coordinate of point B by -1. -> B' = (-x, y)

Step 2: Now, you have the coordinates of point B' as (-x, y). You can name the location of B' using this ordered pair.

> B' = (-x, y)

Step 3: To determine the distance between point B and B', you can use the distance formula. The distance formula calculates the distance between two points (x1, y1) and (x2, y2) as follows:

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates of point B are (x, y), and the coordinates of point B' are (-x, y).

Distance = sqrt(((-x) - x)^2 + (y - y)^2)

=> sqrt((-2x)^2 + 0)

=> sqrt(4x^2)

=> 2x

1 is the answer

Step-by-step explanation:

Number of possible outcomes = 10

Total number of outcome = 10

Probability = \( \frac{Number \: of \: possible \: outcomes}{Total \: number \: of \: outcome}\)

\( = > \frac{10}{10}\)

\( = > 1\)

Hence, the probability of finding number less than or equal to 10 is \(1\)

The given information mentions the sample mean and sample standard deviation of San Francisco student scores on the most recent Scholastic Aptitude Test (SAT) examination in mathematics.

To fully interpret the given information, we would need the numerical values of the sample mean and sample standard deviation. The sample mean represents the average score of the students on the SAT math examination, while the sample standard deviation measures the variability or spread of the scores around the mean.

These statistics provide valuable insights into the performance of San Francisco students on the SAT math examination. The sample mean gives an indication of the typical score achieved by the students, while the sample standard deviation helps assess the dispersion or diversity of scores. A higher standard deviation suggests a wider range of scores, indicating greater variability among the students' performance. Conversely, a lower standard deviation suggests more consistency in scores.

Without the specific values of the sample mean and sample standard deviation, we cannot provide further analysis or interpretation of the data.

The total exposure provided by the drug between t=0 and t=4 is approximately 112.18 ng/ml-hours.

Here, we have,

To find the total exposure provided by the drug between t=0 and t=4,

we need to calculate the definite integral of the concentration function

C = 15t\(e^{-0.2t}\) with respect to t over the interval [0, 4].

The formula for the total exposure is given by:

Exposure = ∫[0, 4] (C(t) dt)

Substituting the given concentration function into the integral, we have:

Exposure = ∫[0, 4] (15t\(e^{-0.2t}\)  dt)

To evaluate this integral, we can use integration by parts. Let's differentiate 15t and integrate \(e^{-0.2t}\) :

∫(15tt\(e^{-0.2t}\)  dt) = -75\(e^{-0.2t}\)  + 15 ∫\(e^{-0.2t}\)  dt)

Now, let's integrate \(e^{-0.2t}\) :

∫\(e^{-0.2t}\)  dt) = (-1/0.2)\(e^{-0.2t}\) = -5\(e^{-0.2t}\)

Plugging this back into the previous equation, we have:

∫(15t\(e^{-0.2t}\)  dt) = -75\(e^{-0.2t}\)  - 75\(e^{-0.2t}\)

Now, we can evaluate the definite integral:

Exposure = [-75\(e^{-0.2t}\)  - 75\(e^{-0.2t}\) ] evaluated from t=0 to t=4

Exposure = [-75\(e^{-0.24}\) - 75\(e^{-0.24}\)] - [-75\(e^{-0.20}\)- 75\(e^{-0.20}\)]

Exposure = [-75\(e^{-0.8}\) - 75\(e^{-0.8}\)] - [-75 - 75]

Exposure = -75\(e^{-0.8}\) + 150

Now, let's calculate the numerical value of the total exposure by substituting the value of \(e^{-0.8}\) ≈ 0.449:

Exposure = -75 * 0.449 + 150

Exposure ≈ 112.18 ng/ml-hours

Therefore, the total exposure provided by the drug between t=0 and t=4 is approximately 112.18 ng/ml-hours.

The statement that is NOT true in a Chi-Square test is "Small values of the chi squared test statistic would lead to a decision to reject the null hypothesis."

This is because if the test statistic is small, it means that the observed values are close to the expected values, and there is no significant difference between the populations. Therefore, a small test statistic would lead to a failure to reject the null hypothesis. In a Chi-Square test, we compare the proportions of specified characteristics in different populations, and we wish to determine whether they are the same or not. If the test statistic is large, it means that the observed values are significantly different from the expected values, and we have evidence to reject the null hypothesis. Finally, the P-value will be small if the test statistic is large, indicating strong evidence against the null hypothesis.
