raising both sides of the equation to a certain power in order to eliminate radicals may result in the creation of extraneous roots
Step-by-step explanation:
-x - 9

You want to get x by itself.
First subtract 9 from both sides of the equation.

+9 +9
-x

Then divide -1 on both sides.
-x/-1

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.
x
Answer:

Step-by-step explanation:
-This is a binomial probability problem.
-Given the probability of catching a cold is 0.03, n=6
#The probability of exactly 3 people catching a cold is calculated as:

Hence, the probability of exactly 3 in 6 people catching a cold is 0.0004928
