Answer:

a) find the attached graph

b) find the attachment no 4 and 5

c)T_(10)= 4.72+1.46(10) = 19.28

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

T_(1) =b_(0) +b_(1)t

Where T_(1) is the linear trend forecast in period t , b_(0) is the intercept of the linear trend time, b_(1) 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)

Y_(t)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 T_(t)= 4.72+1.46t                         (1)

T_(10)= 4.72+1.46(10) = 19.28

Final answer:

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.

Explanation:

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.

Quadrilateral MBPV is similar to quadrilateral GKDF. BP = 78 mm, KD = 30 mm , and FD = 45 mm. What is VP? Enter your answer in the box □mm.

Answers

Answer:

  VP = 117 mm

Step-by-step explanation:

Corresponding sides of similar quadrilaterals are proportional.

  VP/FD = BP/KD

  VP = FD·BP/KD = (45 mm)·(78/30) . . . . multiply by FD; fill in the givens

  VP = 117 mm

An automobile traveled 106 miles in 2 hours. What was average speed? Use the formula d = rt .104 mph
0.02 mph
53 mph
108 mph
212 mph

Answers

The average speed of the automobile is 53mph.

Description of average speed

Average speed is the total distance travelled by the automobile (106 miles) divided by the total hours travelled by the automobile (2 hours). It is the rate of the movement of the automobile.

Determining the average speed

Average speed = total distance travelled / total time travelled

106 / 2 = 53 mph

1. Line L passes through point (-1, 2) and (-3,-2) on a coordinate plane. LineM passes through the points (1.1) and (-1, W). For what value of W will make
line L and line M parallel.

Answers

Answer:

Slope of a line passing through (x_(1),y_(1)) and (x_(2) , y_(2)) is given by:

(y_(2)-y_(1) )/(x_(2)-x_(1))

Now,

Slope of line L, (m) = (-3-(-1))/(-2-2) = 0.5

Slope of line M, (n) = (-1-1)/(W-1) = (-2)/(W-1)

If the lines L and M are parallel to each other,

m = n

or, 0.5 = (-2)/(W-1)

or, 0.5 (W - 1) = -2

or, W - 1 = -4

or, W = -3

Therefore the required value of W is -3.

For this case, what we should do is use the given equation.
 A = P (1 + r) ^ t
 Substituting values we have:
 3900 = 1100 * (1 + 0.04) ^ t
 Clearing t we have:
 (1.04) ^ t = (3900) / (1100)
 log1.04 ((1.04) ^ t) = log1.04 ((3900) / (1100))
 t = log1.04 ((3900) / (1100))
 t = 32.3 years
 Answer:
 the time will be:
 t = 32.3 years
