<h3>
Answer: B) The time to complete a specific task.</h3>
For any two different time values, it is possible to find the midpoint or average of them. For instance, if it takes 10 minutes to do the task on Monday, and then 11 minutes to do the task on Tuesday, then it takes (10+11)/2 = 21/2 = 11.5 minutes to do the task on average. Because we are able to find a midpoint like this, and a decimal midpoint makes sense, this means time is a continuous variable.
In contrast, the number of new hires must be a whole number. If we had 10 hires on Monday and 11 hires on Tuesday, then it doesn't make sense to say we hired 11.5 people. So choice A is ruled out. Similar situations play out with choices C and D, which is why we can rule those out too. Choices A, C and D are discrete variables.
Answer:
5, 7, 9, 11
Step-by-step explanation:
Solve the inequality
w - 4 < 8 ( add 4 to both sides )
w < 12
w ∈ { 5, 7, 9, 11 }
Part A you would just distribute your 3 to your X and your 5. After doing that you would get 3x+15+x=4x. Next you would combine like terms, meaning combine your x's together that is on the same side of your equal sign. So you would add 3x and x. When finished with that you would get, 4x+15=4x. You would then subtract your 4x on both sides of your equal sign. You then would get 15=0 which is no solution.
Part B you would distribute your 4 to your 1 and -x. After doing this your equation should then look like 4-4x=5x+8. Next you would try to get your like terms together. You would add 4x on both sides of your equal sign. Your equation should then look like 4=9x+8. Next you would subtract your 8 on both sides of the equal sign because your getting your terms together. Your equation should then look like, -4=9x. This answer would be one solution.
Part C you would combine your like terms, meaning add your 2x and x together to get your equation looking like, 3x+5=5+3x. You can tell just by looking at this equation it's going to be a infinite number of solutions.
Hope this helps! (:
