Answer: The margin of error = 
Step-by-step explanation:
Given
Sample size (n) = 1000
Population proportion = 0.4
= 1 - confidence level
= 1 - 0.95
= 0.05
= 0.03
The margin of error change to 
to
We have the following number:
23.5
This number can be written as:
23 + 0.5
Or:
23 + 1/2
So, the new expression gives us two new numbers. In this way, we can say that:
23 = Twenty three
1/2 = a half
In conclusion, the number 23.5 can be written as follows:
<em>23.5 = Twenty three and a half</em>
Answer:
.
Step-by-step explanation:
Answer:
x = 23
Step-by-step explanation:
The marked angles are "corresponding," hence congruent:
8x -27 = 7x -4
x = 23 . . . . . . . . . add 27-7x to both sides
Answer:
45
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
2x - 12 + 2x + 17 + 9x - 7 = 180 add like terms
13x - 2 = 180 add 2 to both sides
13x = 182 divide both side by 13
x = 14
m<X = 2x + 17 replace x with 14
2*14 + 17 = 45
