Answer:the steps you used to solve the equation and find the amount of Carrie's allowance. Linear equation: 14a + 13a = 23; 27 a = 14; a = 14/28
Step-by-step explanation:
1. change the fraction using the lowest common dominator
2. combine the like terms of the variable
3. use the subtraction property of equality
4. Check all the occurred
The answer is 76/98 because 22+76 is 98
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
