Step-by-step explanation:
Let's call the floor which Moses started at x. Going down decreases the floor number and going up increases the floor number. We then form the equation which is the same as

Answer:
x = 6
Step-by-step explanation:
We want to solve:
First, isolate the variable by moving all the terms with x to one side and all the constants to the other side:
Combining the fraction on the left, we get:
6/3 = 2, so:
2x = 12
Dividing both sides by 2 yields:
x = 6
Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion = 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
(From the z tables)
The margin of error is calculated by using the formula:
M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%
