The second image where the first row is x-1 y-4.5. The points go further towards the bottom from left to right, unlike the others that point up.
Answer:
270 miles
Step-by-step explanation:
We know the formula for distance
d = rt where r is the rate and t is the time
d = 90 mph * 3 hours
d = 270 miles
<span>d=20,009 + 0.15n
</span>$22,100 = 20,009 + 0.15n
$2091 = 0.15n
n = 2091/.15 = 13940
B. Using no definite pattern.
Answer: 95040
Step-by-step explanation:
It is important to note that selection and arrangement are two different things in permutation and combination study. In the scenario above, we have 12 books, out of which 5 is to be arranged on a shelf. The answer prescribed by 12C5 which gives 792, only solves the selection process of choosing 5 books from a total of 12. Every 5 books picked will also have to be arranged on the shelf which is solved as n!(number of ways of arranging n different objects)
Hence, to arrange 5 books from a total of 12 books on a book shelf is
nCr * r!
12C5 * 5!
792 * 120
= 95040
