Answer:

19 ms

Step-by-step explanation:

We need to find the time it takes for the sound from the 6th row gets to the conductor.

Since there are 6 rows and each row is 3 feet apart, since the orchestra is arranged in a semi-circular manner around the conductor, the distance from the 6 th row to the 1st row is (6 - 1) × 3 = 5 × 3 = 15 feet.

Now, since the conductor is 6 feet from the first row, his distance from the 6th row is 15 feet + 6 feet = 21 feet.

So, time approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note, t = distance between 6th row and conductor/speed of sound.

Speed of sound = 343 m/s

distance between 6th row and conductor = 21 feet. In meters, it is 21 × 0.3048 m = 6.4008 m

t = 6.4008 m ÷ 343 m/s

= 0.019 s

= 19 ms

Answer:not enough information

Step-by-step explanation:

Using definition of range = greatest - lowest , we found that given statement is false.

Range of a data is the difference between the highest and lowest quantity in the given  data.

For example : Given data is 2,5,9,5,1

Range of this data = Highest - Lowest = 9-1 =8

Given the data of the number of appearances made by 7models

Median = 5

Range = 5

If the fewest magazine appearances is 3

We know that Range = Greatest number of appearances - fewest appearances

⇒ 5 =  Greatest number of appearances - 3

⇒ 5 +3 = Greatest number of appearances

∴Greatest number of appearances = 5+3 = 8

But given is that the Greatest number of appearances will be 9 in the given statement.

∴ The given statement is false.

Since the graph is nonlinear, you can rule out answers that say or suggest 'constant change.'

Answer:

(1) x-y-2z=-6 , (2)  3x+2y=-25 , (3) -4x+y-z=12  

Step-by-step explanation:

Multiply (3) by 2,

-8x + 2y - 2z = 24

subtract above equation from (1)

9x - 3y = -30 --> 3x - y = - 10

subtract above equation from (2)

3y = -15 --> y = -5

Put y value back into (2)

3x + 2(-5) = -25 --> 3x - 10 = -25 --> 3x = -15 --> x = -5

Put x and y values into (3)

-4(-5) + (-5) - z = 12 --> 20 - 5 - z = 12 --> 15 - z = 12 --> z = 3

Step-by-step explanation:

Given that the price of the ticket at the beginning of the season is $49.64 and the ticket price decrease by $0.41 for every loss

a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:

Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71

b) The cost of a ticket for the next game given they have 31 losses is:

Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93

The first set:

" {(0, 1), (1, 2), (2, 3), (3, 3)}"

Represents a function.

A function is a relationship that maps elements from a set (inputs) into elements from another set (output). Such that each input can be mapped into only one output.

Then, for example, the second set:

{(0, 1), (1, 2), (1, 3), (2, 5)}

Is not a function, because the input x = 1 is being mapped into y = 2 and y = 3.

The only case where the inputs are not repeated is on the first set:

" {(0, 1), (1, 2), (2, 3), (3, 3)}"

Where no input is repeated, so this is a function.
