A)12

B)16

c)20

d)24

Answer:
answer:

B

the equation:

3x-7=9+2x

step 1: subtract 2x from both sides

x-7=9

step 2: add 7 to both sides

x=16

B

the equation:

3x-7=9+2x

step 1: subtract 2x from both sides

x-7=9

step 2: add 7 to both sides

x=16

Answer:

**Answer:**

Option B

**Answer: a = b*r/n**

**Step-by-step explanation: Hope this helps :^)**

**Answer:**

5)** **35 / 100 = X / 74 X = 2590 / 100 = 25.9

or .35 * 74 = 25.9

6) 78 / 95 = X * 100

X = 7800 / 95 = 82.1 %

or X = 78/95 * 100 = 82.1 %

7) 60/100 * X = 28

X = 2800 / 60 = 46.7

Or .6 * X = 28

X = .28 / .6 = 46.7

The interval level of measurement is a number scale that classifies both order and the value change between each number. For example, a ruler has intervals 1, 2, and 3 inches. The distance between 1 to 2 inches is the same as the distance between 3 to 4 inches.

y-intercept, b0 = 4.7.17

Slope, b1 = 1.46

What is the forecast for year 10? 19.283

Round your interim computations and final answer to two decimal places.

**Answer:**

**a) find the attached graph**

**b) find the attachment no 4 and 5**

**c)**

**Step-by-step explanation:**

a) A trend pattern exist if the time series plot gradually shifts to higher or lower values over a long period of time

**find the attached graph**

b) Liner Trend Equation

Where is the linear trend forecast in period t , is the intercept of the linear trend time, is the slope of the linear trend line, t is the time period

now computing the slope and intercept

**formula is attached ( 3 no attachment)**

is the value of the time series in period t, n is the number of time periods

Y(bar) is the average value and t(bar) is the average value of t

**due to unavailability of equation in math-script i attached the calculation part of this question( 4th and 5th no attachment)**

thus the linear trend equation is ** (1)**

To find the **Mean Squared Error **(MSE), you can calculate the difference between the actual and predicted values, square these differences, and find their average. To forecast for a specific year, you can insert the year as the 'x' value into the simple linear regression equation.

The question is asking for the Mean Squared Error (MSE) for a simple linear regression model based on the enrollment data of Jefferson Community College. This involves using the y-intercept (**b0**) and slope (**b1**) values provided, and the given data points. You can calculate the MSE by taking the difference between the actual and predicted values (errors), squaring these differences, and then finding the average of these squared differences for the entire dataset.

Then, to forecast for year 10, you use the simple linear regression model equation, y = b0 + b1*x, where y represents the predicted enrollment. So, for year 10, you would insert 10 as your 'x' value into the equation, which results in the **forecast value **provided which is 19.283.

The **factored expression **of the expression x^3 + 4x^2 +5x + 20 is (x^2 + 5)(x + 4)

The **expression **is given as:

x^3 + 4x^2 +5x + 20

Group the **expression **into two

(x^3 + 4x^2) + (5x + 20)

**Factorize **each group

x^2(x + 4) + 5(x + 4)

Factor out x + 4

(x^2 + 5)(x + 4)

Hence, the **factored expression **of the expression x^3 + 4x^2 +5x + 20 is (x^2 + 5)(x + 4)
