There are 120 ways in which 5 riders and 5 horses can be arranged.
We have,
5 riders and 5 horses,
Now,
We know that,
Now,
Using the arrangement formula of Permutation,
i.e.
The total number of ways 
,
So,
For n = 5,
And,
r = 5
As we have,
n = r,
So,
Now,
Using the above-mentioned formula of arrangement,
i.e.
The total number of ways ,
Now,
Substituting values,
We get,
We get,
The total number of ways of arrangement = 5! = 5 × 4 × 3 × 2 × 1 = 120,
So,
There are 120 ways to arrange horses for riders.
Hence we can say that there are 120 ways in which 5 riders and 5 horses can be arranged.

Your answer is 6 gallons of gas.
Since the car can travel 32 miles per gallon(mpg), you would need to do 192 divided by 32 to get your answer. To verify it you can do 6(answer) times 32. Your answer would be 192, meaning you're right.
Answer:
The answer is B I just took the test:)
Step-by-step explanation:
<span>One nonzero function that satisfies f′(x)=4f(x) can be found by using the constant 'e' and its derivative rules. If we define f(x) = e^(4x), the first derivative f'(x) can be found via the chain rule to be 4*e^(4x) or the 4*f(x) as desired.</span>
Divide the number of defective by the number checked:
26/190 = 0.1368
Multiply that by 1000:
0.1368 x 1000 = 136.8
Round up to 137
Out of 1000 cd’s 137 would be defective
