The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legi

Romashka [77]

Answer:

We can not solve for a unique cost for each soldier.

Step-by-step explanation:

Let x be the daily cost for legionaries and y be the daily cost for archers.

Upon using our given information we will get a system of linear equations as:

$3x+3y=10...(1)$

$x+y=3...(2)$

Now we will solve for x from our 2nd equation,

$x = 3-y$

Now we will substitute this value in our 1st equation.

$3(3-y)+3y=10$

$9-3y+3y=10$

We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.

First, let’s break this down. What exactly are we looking at here? Well, Daisy measured the heights of 20 plants (in cm). The table, under Frequency, shows the # of plants that fit within a certain height range, shown on the left under Height of Plants (h).

Now, it says to take the midpoints of each group to figure out an estimate of the mean height. To find the mean, you add up all the totals and divide it by the # of items. So, let’s go through each row.

Midpoint of 0-10 is 5, and Frequency is 1, so that gives us 5.
Midpoint of 10-20 is 15, Frequency is 4, and 15x4=60.
We continue this with the other rows by finding the midpoint & multiplying the midpoint by the frequency (if the frequency is greater than 1). This gives us the numbers:

175 (25x7)
70 (35x2)
135 (45x3)
165 (55x3)

Now, we add these all together.
5+60+175+70+135+165=610

Finally, we divide 610 by the # of items (remember, there are 20 plants so we divide by 20) and 610/20 is 30.5.

FINAL ANSWER:

Thus, if I calculated correctly (which I hope I did lol), our estimate for the mean height of a plant is 30.5 cm!

Someone help find the value of these music notes !!!

Elodia [21]

Answer:

See below

Step-by-step explanation:

1) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

2) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

3) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with a dot)

4) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

5) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 note (eighth note with dot)

6) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

7) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

8) 2/16 + 2/16 = 4/16 = 1/4 note

9) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

10) 1/16 + 1/16 = 2/16 = 1/8 note

11) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with a dot)

12) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

13) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 note (eighth note with dot)

14) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

15) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

16) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

17) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

18) 1/16 + 1/16 = 2/16 = 1/8 note

19) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

20) 2/16 + 2/16 = 4/16 = 1/4 note

21) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

22) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

23) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

24) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

25) 1/16 + 1/16 = 2/16 = 1/8 note

26) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

27) 2/16 + 2/16 = 4/16 = 1/4 note

28) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with dot)

29) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

30) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 (eighth note with dot)

Bonus Question:

1/4 + 1/8 + 1/8 + 1/4 + 1/16 + 2/8 + 1/16 + 1/4 + 1/16 + (2/16+1/8) = 4/16 + 2/16 + 2/16 + 4/16 + 4/16 + 1/16 + 4/16 + 1/16 + 2/16 + 2/16 = 26/16 = 13/8 (whole note with dot tied with eighth note with 2 dots)
