A football stadium contain 80% of its full capacity of spectators for a grand final match. At the end of the game, spectators le
nekit [7.7K]

Answer:

A. 30000

B. 12000

Step-by-step explanation:

Find out how much spectators leave in 1 minute.

1 second = 5

1 minute = 5 x 60 = 300 (60 seconds)

20 minutes = 300 x 20 = 6000

Since there were only 80% of the full capacity of spectators and after minutes it became 60%...

80% - 60% = 20%

20% = 6000

1% = 6000 ÷ 20 = 300

100% = 300 x 100 = 30000

1 minute = 300 spectators leaving

1 hour = 300 x 60 = 18000 (60 minutes)

30000 - 18000 = 12000

What are the characteristics of the graph of the inequality x ≥ -2? The ray will move to the left. The ray will move to the righ
Alenkasestr [34]

Answer:

Step-by-step explanation:

The inequality x ≥ -2 is graphed on a number line.  -2 is the smallest possible value.  All subsequent values are larger and therefore lie to the right of -2.

Thus, the following are true:

1.  The ray will move to the right (because x begins at -2 and increases, which means moving to the right on the number line).

2.  It will use a closed circle (because x = -2 is part of the solution set).

Does the residual plot show that the line of best fit is
Iteru [2.4K]

Answer:

e_1 = 3.5-4.06= -0.56

e_2 = 2.3-2.09= 0.21

e_3 = 1.1-0.12= 0.98

e_4 = -2.2-(-1.85)= -0.35

e_5 = -4.1-(-3.82)= -0.28

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.

Step-by-step explanation:

The correct formula for the residuals is given by:

e_i =y_i -\hat y_i

Who represent the observed value minus the predicted. We can find the individual residuals and we got:

e_1 = 3.5-4.06= -0.56

e_2 = 2.3-2.09= 0.21

e_3 = 1.1-0.12= 0.98

e_4 = -2.2-(-1.85)= -0.35

e_5 = -4.1-(-3.82)= -0.28

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.
