Answer: 25 computers will be selected
Step-by-step explanation:
Where: Z -value at 95% confidence = 1.96; SD = Standard deviation = 10 minutes; N = Sample size; Margin error = 4 minutesSubstituting;4 = 1.96*10/Sqrt (N)Sqrt (N) = (1.96*10)/4 = 4.9N = 4.9^2 = 24.01 ≈ 25
The answer is [4,6) because a square bracket (closed) denotes that the lower bound is inclusive, and the parenthesis (open) denotes that the upper bound is exclusive.
As you can see on the number line, there is a closed dot on 4 and an open dot on 6.

Answer:
x=11
Step-by-step explanation:
6x-3(x+8)=9
Using the distributive property, we can turn 6x-3(x+8)=9 into 6x-3x-24=9, which simplifies to 3x-24=9 by combining like terms. Now, if we add 24 to both sides, we get 3x=33. By dividing both sides by 3, we get x=11.
Check:
66-3*19=9
66-57 does in fact equal 9.
