Answer:
The correct answer is "(18, 30) minutes".
Step-by-step explanation:
Mean,
= 24
Standard deviation,
= 2
The range of minutes where 99.7% of individuals completed the quiz will be:
= 
On substituting the values, we get
= 
= 
now,
= 
=

= 
= 
i.e., 18 to 30 minutes
First you need to find the surface area of the wall that was painted, and then add the additional area in the hallway that was painted.
The wall that was painted was 9 feet by 10 feet, or 90 square feet. 90 square feet plus the additional 46 square feet in the hallway is 136 square feet, which is the total area that the paint covered.
Therefore the solution is 136 square feet.
Answer:
f= 0.7
Step-by-step explanation:
Multiply by reciprocal on both sides: 4/3 * 3/4(5f-3) = 3/8 * 4/3 f
Then, you are left with: 5f-3 = 1/2
Then you subtract by three on both sides to get: 5f=3.5
Finally, divide by 5 on both sides to get: f=.07
