Some studies of the relationship between car color and frequency of accidents have found that red cars are more likely to be in

accidents than black cars, despite how visible they are. Some experts warn that we should not conclude red cars are less safe than black cars because of possible confounding. Which of the following best describes what confounding means in this situation?
a. lt can be hard to determine whether red cars or black cars are more visible on modern
b. Much of the data on car color and accidents is contradictory, thus making it hard to draw
c. Much of the data on car color and accidents is subject to bias, thus making it hard to draw

What you need to know in order to answer this:

       In math, the symbol " ! " is used to indicate "factorial".
       "Factorial" means the product of the integers from 1
       up to the number.

Examples:

       
2 !  =  "two factorial"  =  1 * 2  =  2

        4 !  =  "four factorial"  =  1 * 2 * 3 * 4  =  24

For this question:

  10 !  =  "ten factorial"  =  1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10

                                       =  3,628,800 .

If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.

And by the way, the points aren't 'free'.  I had to
give you some information in order to earn them.

In a paint factory, an old conveyer line has filled 10 barrels of paint, and is filling more at a rate of 2 barrels per minute.
Leviafan [203]

Answer:

see below

Step-by-step explanation:

First line:

y = mx+b  where m is the slope and b is the y intercept

y = 2x + 10

Second line

y = mx+b

y = 3x+0  since there are no barrels filled on this line when they flip the switch

Setting the two equations equal

2x+10 = 3x

Subtract 2x from each side

2x+10-2x= 3x-2x

10 = x

Each line will have filled 10 barrels when they numbers are equal.
