The steps below are presented in order to arrive to the value of k of the given equation.
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,
(k + 12/ k)(k) = 8(k)
Then, we simplify,
k + 12 = 8k
We then, subtract 8k to both sides of the equation,
k - 8k + 12 = 8k - 8k
Simplifying,
-7k + 12 = 0
Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,
k = 12/7
Answer: a. 1/6. b. 2/3. c. 5/6
Step-by-step explanation:
Number of adults randomly selected= 6
a. Finding the probability of adults that have cheated on an examination before is exactly 4.
The numbers are 1, 2, 3, 4, 5 and 6.
Probability of chosen exactly 4 will be 1/6 since 4 can only occur once.
b. More than 2means 3,4, 5 and 6.
Probability that the number of adults that have cheated on a test or exam is more than 2 will be:
4/6 = 2/3
c. At most 5 means 1,2,3,4 or 5
This will give 5/6
The answer is c. we add 4x^4+x^4. then cancel the -x^2+x^2 and also the -x and x . so, we are left with the -1. that's why the answer is c
You have 4 walls, 2 with length 12 feet, 2 with length 15 feet and each of them has a height of 12 feet
so you sum all the lengths and then multiply it by the height to get the total area
total length=2*(12+15)
=2*(27)
=54
total area=total length*ceiling height
=54*12
=648 feet^2 to cover all walls with wallpaper
