Step-by-step explanation:
let Remus' money be = y
Aaron's = 5/7 y
3/5 * 5/7 y = 3/7 y
balance= 2/7 y
y - 2/7y = 2820
5/7 y= 2820
y = 2820*7/5= 564*7 = 3948
Answer:
37 degrees
Step-by-step explanation:
Tan x = 4.8/6.3
Tan x = 0.76
Tan^-1 (0.76) = 37 degrees
Answer:
D. -cos(nw0t)
Step-by-step explanation:
Subtracting 90° from the argument of the sine function shifts its graph 90° to the right, putting the negative peak on the y-axis. That corresponds to the negative cosine function, choice D.
Step-by-step explanation:
I am not sure i understand the text you put there.
what I think is clear is to find the expected number of the appearances of the number 3 when spinning the spinner 100 times.
to do this we start by checking the given information.
and we see that the given table based on the result of in total 50 spins (7+8+9+7+11+8).
when spinning the spinner additional times, we can expect the same structure of distribution of the individual possible results as before. we just scale everything to the new size of the overall sample.
before, with 50 spins, we saw the number 3 9 times.
so, with 100 spins, which is 2×50, we expect to see the number 3 then 2×9 = 18 times.
Answer:
Filling the table;
left-hand side from top to bottom, empty spaces are;
500 pesos
20 pesos
60 pesos
On right hand side;
the only space is 24 dollars
Step-by-step explanation:
Here, we want to complete the given table
The key to complete the table is knowing the exchange rate
Since 250 dollars have 5,000 pesos
what this mean is that 1 dollars is 5000/250 = 20 pesos
And 1 pesos = 250/5000 = 0.05 dollars
25 dollars in pesos will be;
25 * 20 = 500 pesos
1 dollars in pesos is 20 pesos
3 dollars in pesos will be 3 * 20 = 60 pesos
480 pesos in dollars will be 480 * 0.05 = 24 dollars
