Answer:
95% Confidence interval: (0.361,0.539)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 120
Number of farmers who reusable cloth bags, x = 54
95% Confidence interval:
Putting the values, we get:
is the required 95% confidence interval for the proportion of adults who have purchased reusable cloth bags.
6/12 and 4/8 are equal fractions, as, when simplified, they share a simplified fraction.
Note that what you do to the denominator, you do to the numerator. Find common denominators for both fractions:
(4/8)/(2/2) = 2/4
(6/12)/(3/3) = 2/4
As you can tell, when they share a common denominator (4), the numerators are the same as well (3).

Answer:
10^2 . . . . see below for additional information or versions of the answer(s)
Step-by-step explanation:
You seem to want 10^<em>exponent</em>, where <em>exponent</em> is an even single digit, not zero.
We choose <em>exponent</em> = 2, so your expression is ...
10^2
__
There are several versions of expanded form. One uses exponents. In that form, the expression above <em>is the expanded form</em>.
Another uses multipliers of 1, 10, 100, 1000, and so on. In that form, the expression expands as ...
10^2 = 1×100
Another expanded form uses individual digits of the expanded form with others set to zero
10^2 = 100
The standard form is ...
10^2 = 100.
_____
We suppose your exponential expression might have another multiplier, such as 2.98:
- exponential expression: 2.98×10^2
- standard form: 298
- expanded form 1: 2×10^2 + 9×10^1 +8×10^0
- expanded form 2: 2×100 +9×10 +8×1
- expanded form 3: 200 + 90 + 8
