The **standard **error **mean **if σ = 64 and n = 64 is 8.

The standard error **mean **is given by the formula σ/√N. In the question provided, we need to note that the standard error mean is designated by σM.

Now applying the formula, we will have this:

σM = 64 ÷√64

The root of 64 = 8.

Therefore, the **standard **error mean is equal to 64 divided by 8 which is 8.

So, we can arrive at the conclusion that given the standard error mean of σ = 64 and n = 64, the standard error mean will be 8.

A straight road named Planet Drive will connect the diner and the community garden.What is the equation of the line that represents Planet Drive? Show your work

As the line intersected the y-axis at x = 4, the equation of the line which represents **planet Drive** to the **community **garden is x = 4.

The shortest distance that separates two points is represented by a line. A line can be horizontal, slanted, or straight. A equation of a line in **slope-intecept form** has been expressed as:

y = mx + b

where,

m is called the slope

b is the y-intercept

From the graph shown, you recognize that the planet drive line is a horizontal as well as the general equation of the a horizontal line is represented as x = a where;

'a' is indeed the **x-intercept **of a line, which is the point at which the line intersects the y-axis.

No because it says purple to green buttons and the student put green to purple so the answer would be 4:3 not 3:4

In a factory, the production hours t and output y are having linear relationship. When the

factory operates for 5 hours per day, it may have the number of outputs of 2000 units and 3500

units for 8 hours of operation.

(a) Model an equation that gives the outputs, y, in terms of operation hours, t, per day.

(b) If the factory wants to have 4500 units of production per day, how long it should operate?

(c) Draw the graph in excel of the production against operation hours t up to first 20 hours.

Considering the **linear relationship **between the variables, we have that:

**a) **The **function **is: y = 500t - 500.

**b) **The factory should **operate **for 10 hours to have a production of 4500 units.

**c) **The **graph **for the first 20 hours of the function is given at the end of the answer.

A linear function, in **slope-intercept** format, is modeled according to the following rule:

y = mx + b

In which:

The coefficientFor the given linear relationship, we have **two points,** as follows:

(5,2000) and (8,3500).

The **slope **is given by change in y divided by change in x, hence:

m = 1500/3 = 500.

Then:

y = 500t + b.

When t = 5, y = 2000, hence we solve for the **intercept **as follows:

2000 = 500(5) + b

b = -500.

Then the **function **is:

y = 500t - 500.

For **4500 units,** the **time **is found as follows:

4500 = 500t - 500

500t = 5000.

t = 5000/500

t = 10 hours.

The table represents a quadratic function. Write an equation of the function in

standard form.

X- -3,-2,-1,0

An **equation** of the** function** in standard form for the given table of values is equal to -2x² - 7x - 6 = 0.

In Mathematics, the standard form of a **quadratic equation** is given by;

y = f(x) = ax² + bx + c = 0

In order to write an **equation** of the** quadratic function** in standard form, we would formulate a system of **equations** from the data provided in the table above as follows:

-6 = a(-3)² + b(-3) + c ⇒ -6 = 9a - 3b + c .......equation 1.

0 = a(-2)² + b(-2) + c ⇒ 0 = 4a - 2b + c .......equation 2.

-2 = a(-1)² + b(-1) + c ⇒ -2 = a - b + c .......**equation** 3.

From equation. 2, we derive:

c = -4a + 2b .....equation 4.

Substituting **equation** 4 into equation 1 and 3, we derive the following **equations**:

-2 = a - b - 4a + 2b ⇒ -2 = -3a + b

-6 = 9a - 3b - 4a + 2b ⇒ -6 = 5a - b

By using the elimination method, the value of a is given by:

[-2 + (-6) = (-3a + 5a) + (b + (-b)]

-2 - 6 = -3a + 5a + b - b

-8 = 2a

a = -4

Next, we would determine the value of b as follows:

-2 = -3a + b

b = -2 + 3a

b = -2 + 3(-4)

b = -2 - 12

b = -14

For the value of c, we have:

c = -4a + 2b

c = -4(-4) + 2(-14)

c = 16 - 28

c = -12.

Substituting the respective values of a, b and c into the standard form of a **quadratic equation**:

ax² + bx + c = 0

-4x² - 14x - 12 = 0

Dividing all through by 2, we have the following **quadratic function**:

-2x² - 7x - 6 = 0

Round each to the nearest dollar and add.

1) Using **order **of **operations**, the solution to the given expression is; 12

2) The estimated cost of groceries if the prices are estimated to the nearest dollar is; $42

How to use order of operations?In mathematics , the acronym for the right **order of operations** is **PEMDAS** which denotes;

3) From the given statement, we are to add 6 to 12, then divide the sum by 4. Thereafter, we divide the quotient by negative nine and then multiply by twenty-four. This is expressed as;

[(6 + 12)/4] = 18/4 = 9/2

Then divide by -9 to get;

(9/2) ÷ 9 = 1/2

Then we multiply by 24 to get;

1/2 * 24 = 12

4) Let us first estimate **each cost **to the **nearest dollar **to get;

$6.47 ≈ $6

$14.72 ≈ $15

Two cars start moving from the same point. One travels south at 16 mi/h and the other travels west at 12 mi/h. At what rate (in mi/h) is the distance between the cars increasing three hours later?

**Answer:**

20 mi/h

**Step-by-step explanation:**

You want the **speed of separation** after **3 hours** between **two cars** that started from the same point. One is moving at **16 mi/h south**, the other is moving at **12 mi/h west**.

Since both cars started from the same point, the speed of separation is the magnitude of the difference between the respective velocity vectors. A graphical representation of the velocity vectors shows them to be the legs of a right triangle. Their difference is the length of the hypotenuse, which can be found using the Pythagorean theorem.

s = √(16² +12²) = √(256 +144) = √400

s = 20

**The speed of separation is a constant 20 mi/h**.

__

*Additional comment*

If the cars did not start at the same point, then the speed of separation would be changing with time. It could be found using the derivative of the distance between the cars, or by considering the car speeds in the direction each car is from the other at the time of interest.

We note that the problem here makes use of a 3-4-5 right triangle, with a multiplier of 4 mph.

When Sam launched a potato from their potato cannon the potato traveled a horizontal distance of 150 feet and, at its highest, reached 90 feet.Part A. Create a graph to represent the scenario. The graph should include at least the x- and y-intercepts and the vertex. (A complete graph consists of axis labels and appropriate scales, ordered pairs for each identified point, the function, and appropriate domain/range.)Part B. Write a function to model the scenario.Part C. Create a table of values to represent the scenario. Be sure to include at least fivevalues. Values should include at least the x- and y-intercepts and the vertex.Part D. Identify how you see the x- and y-intercepts and vertex in the table, graph, and equation.(PLEASE HELP)
