Answer:
<h2>C) 12x + 9</h2>
Step-by-step explanation:
The distributive property: <em>a(b + c) = ab + ac</em>.
The account decreased by
7,400×0.265=1,961
The account at the end of the year
7,400−1,961=5,439
Arjun should have divided both sides of the equation by 7 instead of multiplying.
We have the following data:
Margin of Error = E = 2.7 % = 0.027
Sample size = n = 900
Proportion of adults in favor = p = 60% = 0.6
We need to find the confidence level. For this first we need to find the z value.
The margin of error for a population proportion is given as:
Using the values, we get:
As, seen from the z table, z=1.65 corresponds to the confidence level 90%. So, the answer to this question is option B
1. Ten
2. Hundred
