Answer:
C
Step-by-step explanation:
This is actually a combination problem as we are trying to select groups of 5 from the 15 qualified trainees.
To do this, we use the combinatorial approach. This is done by using the formula 15C3 = 15!/(15-3)!3!
This gives a value of 455
You can easily tell if Keisha will finish reading the book by this equation:
y = 325 - 25x
where y is the number of pages left, and x is the number of days. A point slope for has a standard form of y - y1 = m(x - x1). Thus, we arrange it in this manner:
y = 25(13 - x)
Then, substitute x = 10:
y = 25(13 - 10)
y = 75
So, Keisha will not be able to finish the book in 10 days. There are still 75 pages left to read.
Answer:
It is < (less than sign)
Step-by-step explanation:
Negative numbers when they keep going up, (-11,-12,-13) they actually become less, not greater. Also heres a tip: If you see the arrows in a number line compared to these signs, try to remember them as good help cause sometimes I get confused then remember. (>,<)
