D. is the answer (sorry for not writing it out, i don’t have the symbol)
Answer:
80
Step-by-step explanation:
No of types of car model = 8
No of color = 10
we can solve this problem by using fundamental principle of counting.
It states that if there are "m" ways to do a thing and there are "n" ways to do other thing then there are "m*n* ways of doing two things together.
For example if there are 3 shirts and 4 pants then there are 3 * 4 different ways to wear combination of shirts and pants.
Similarly in this problem there 8 different car model and 10 different colors hence there are 8 * 10 = 80 different ways to select combination of car model and colors.
Thus there are 80 number of cars Nick could design
Answer:
The answer is 5 times
Step-by-step explanation:
First, we need to read the change in price in 2000 and 2007, from the graph.
So, the change in price in 2000 was $0.14 and in 2007 it was $0.71.
Now, we do the same thing we always do when comparing two values - we divide them. So:
0.71 / 0.14 = 5.07
Of course, we could multiply these values with 100, in order to avoid decimal numbers. Then we would get:
71 / 14 = 5.07
We could also divide this in the form of fractions:
71/100 / 14/100 = 5.07
There are several ways we could divide rational numbers, but the result will always be the same.
Change in price in 2007 was around 5 times greater than the change in 2000.
I hope this helps!!;-)
